[et-mgmt-tools] Fwd: OCaml bindings - Windows installer
Might interest some people on this list ... --- Begin Message --- This is a Windows installer for the OCaml libvirt bindings and programs: http://libvirt.org/sources/ocaml/ocaml-libvirt-0.4.0.1.exe If someone has a 'virgin' Windows system and could test that the above installer works, particularly for Windows < Vista and for Windows which has not had any GTK/MinGW development tools installed. About 90% of the size of the installer is down to the GTK DLLs and configuration files which need to be carried along to support the GTK graphical program (Virt Control). It's possible that I haven't placed the GTK files in exactly the right place, so instead it is using my own GTK development environment. Screenshots showing the installer in action: http://annexia.org/tmp/wininstaller-1-desktop.png Desktop, nothing installed, showing the installer icon. http://annexia.org/tmp/wininstaller-2-packages.png List of required, recommended and optional subpackages. http://annexia.org/tmp/wininstaller-3-instpath.png Select the installation path. http://annexia.org/tmp/wininstaller-4-installdone.png Install complete. Notice the desktop icons, ... http://annexia.org/tmp/wininstaller-5-menu.png ... and the menu entries and uninstaller program. http://annexia.org/tmp/wininstaller-6-virtctrl.png Running Virt Control. http://annexia.org/tmp/wininstaller-7-uninstall.png After uninstall. Notice that the desktop icons have gone. The installer uses NSIS (the Nullsoft Scriptable Install System, http://nsis.sf.net/) and is reasonably well integrated into the autoconf / make build system. In particular if you are compiling under Windows and NSIS is installed, then a simple './configure --with-nsis; make wininstaller' will build a Windows installer. This is something to look at if libvirt wants/needs a Windows installer.

[et-mgmt-tools] [PATCH 1/2] Virt-viewer: Abstract viewer_start entrypoint
This patch adjusts src/main.c so that there is an entrypoint called
viewer_start which will be used by the plugin.
Note the header file ("viewer.h") and the function is private and
internal to virt-viewer.

[et-mgmt-tools] Virt-p2v 0.9.1 - a physical-to-virtual migration live CD
I'm pleased to announce the latest version of virt-p2v, the open source physical-to-virtual migration live CD. http://et.redhat.com/~rjones/virt-p2v/ This is almost a complete rewrite, although largely based on the code in the old shell script. Amongst the new features are: - writes a configuration file for Xen/QEMU/KVM - auto-detects operating system(s) present on the machine - configurable so you can build customer-specific live CDs - auto-detects CPU & memory - support "ISO attachments" for quick development updates - allowed to specify an SSH username (not just 'root') - progress bar during copy - hopefully fixed the "stops at 4GB" bug reported by another user - lots and lots of bugfixes Documentation: http://et.redhat.com/~rjones/virt-p2v/virt-p2v.1.html Rich. -- Emerging Technologies, Red Hat - http://et.redhat.com/~rjones/ Registered Address: Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SL4 1TE, United Kingdom.

Sorry if contacting you directly is not the correct way to do this, but I could only find you email address in the readme file. It appears that currently it cannot properly handle machines running on linux software raid. The disks appear only as /dev/* partitions, and running virt-p2v on them fails during the snapshot operation, probably because the partitions are type mdraid. However even when the partition is change to 83, it still acts really weird. Looking through virt-p2v it appears that it can only handle regular partitions and lvm. I was just curious if you had thought of adding support for md devices, otherwise I might try to do it myself. Any help is always welcome. Out of interest, which version are you using?

However, this *does *exist in "/usr/lib/xen/bin/qemu-dm" going to test it with this in the config. Works! woo hoo! Ah right, that's actually a bug in the code around here (line 1384 in the current development version): let devices = let emulator = match state.hypervisor with | Some Xen -> [leaf "emulator" "/usr/lib64/xen/bin/qemu-dm"] (* XXX lib64? *) The fix for this is for virt-p2v to connect to the remote hypervisor (using libvirt/libvirtd) and issue a virConnectGetCapabilities call. In the capabilities XML there is the correct emulator path. However I haven't got around to this yet. Interesting minor configuration error. Something to ask what architecture (i386 or x86_64) at the begining of the p2v could fix that based on a user choice, That seemed to fix it! :-D I have a few other machines I can test addendums to virt-p2v. Not everyone uses 64 bit dom0's even though everyone should. :-) Please do!

Lester M. wrote: Quick question, are fedora users able to do paravirt migrations with fedora 8 currently? I noticed that for fedora 8 in particular there is no xenU kernel package or update, so when a system is migrated it is as a full-virt. For paravirt-to-paravirt you can do an ordinary migration, like this: virsh migrate [--live] guest xen://otherhost/ But I'm guessing you mean P2V, and converting the physical machine into a paravirt guest (rather than as at the moment into a fullvirt guest), and the answer to this is _yes_, but not as far as I know in Fedora. For RHEL you can install the PV drivers after doing the P2V. The eventual plan for virt-p2v is to be able to do this automatically during the P2V operation. Hence I added the RHEL PV binaries to virt-p2v in preparation for this: http://hg.et.redhat.com/virt/applications/virt-p2v--devel?cs=bc808b3656fb Fedora policy prevents these drivers from being included in Fedora, because they are not part of the Linus tree. You'd have to compile them yourself and maintain them (or help get them upstream ...) BTW, installing these drivers doesn't make the guest completely paravirtual. The guest will still look like a fullvirt guest, particularly w.r.t. how it handles the CPU & memory. However they do improve the important things -- disk and network -- which means you get almost all of the performance benefit of paravirtualization. Oh, another thing, a cool feature would be to have a select choice of which type of virtualization to use (para or full.). Its a nice feature to have, but with the current "state of xen" I guess the biggest hurdle which may add "bloat" to the iso image would be to include xenU kernels. :-( See above - yes this in the eventual plan for virt-p2v. I remember reading *somewhere* about fedora being behind with xen based kernels and backporting changes, would that impact that idea somewhat? Yes. The latest Linux kernel supported by XenSource is something ancient, and Red Hat devotes some developer resources to forward-porting Xen to newer Linux kernels, but even so we are still a bit behind.

Which version of virt-top is this? Script mode is designed to run forever. If used in conjunction with --csv then you'll get an ever longer CSV file. But you also add either '-n ' or '--end-time '[1] to make it stop early (or just kill it instead). For example: virt-top -c test:///default --script --csv /tmp/test.csv -n 10 will run for 30 seconds, produce a 11 line (10 measurements + title) CSV file, and then exit. If it _doesn't_ do that, then please file a bug. The virt-top manpage explains all the options in some detail. Rich.

(b) If the virtual machine has either Xen paravirt drivers installed or is completely paravirtualized, Xen has its own block device infrastructure and the disks appear as /dev/xvdX. Virt-p2v attempts to rewrite /etc/fstab after migration so that drive names are rewritten correctly. If it doesn't get this right then you may need to boot the virtual machine in single user mode and edit /etc/fstab. (If you have to do this, let me know some details and the contents of /etc/fstab.p2vsaved and /etc/fstab because it's a bug). Situation (3)(a) above is slow.

This is because support for the "ask" method of network configuration wasn't implemented in virt-p2v version 0.5 (but it is in newer versions but they don't support cciss). I'm going to add support for cciss real soon since it's popular / important on HP hardware, but it seems like version 0.5 is working for you at the moment. BTW, with version 0.5 you'll need to write your own configuration file to start up the guest.

The pertinent error is: EXT3-fs: blocksize 1024 too small for device blocksize 4096. The problem is convoluted. In order to avoid modifying the underlying disk, we use a device mapper feature to make a writable snapshot of the partitions that we will change (such as the root partition because we'll change /etc/fstab). The writable snapshot stores changes in a ramdisk so that at next reboot all the changes magically disappear and we haven't modified the original disk. All well and good but the writable snapshot ends up with the same blocksize as the ramdisk (4096 by default). Since your filesystem is from Fedora Core 1, it has a blocksize of 1024, and a limitation of ext3 is that it cannot mount a filesystem with blocksize smaller than the device blocksize. Solution should be the following. When the ramdisk boots, go into grub and add: ramdisk_blocksize=1024 to the kernel command line.

[et-mgmt-tools] GLLUG meeting in London this Saturday - talk about Cobbler
[Forwarded from the Greater London Linux Users Group mailing list] -- There will be a Gllug meeting taking place on the 15th of March, starting at 2pm, in the New Cavendish Street campus of Westminster University. Google map for the location is at http://shorterlink.org/4059 We've got three speakers lined up: Matthew King - A beginner's introduction to Asterisk. An explanation of SIP, IAX, Zap, and how they work in an Asterisk dialplan. He will also be covering common pitfalls in Asterisk installation. Karanbir Singh - Automated systems provisioning with Cobbler and CentOS. A brief intro to cobbler itself and then a live demo on setting up real machines and Xen + VMware virtual machines. Cobbler is a Linux boot server that allows for rapid setup of network installation environments. With a simple series of commands, network installs can be configured for PXE, reinstallations, and virtualized installs using Xen or KVM. Cobbler uses a helper program called 'Koan' (which interacts with Cobbler) for reinstallation and virtualization support. John Hearns - Computing clusters. There may be time at the end of the meeting for a couple of lightning talks.

[et-mgmt-tools] ANNOUNCE: virt-p2v 0.9.7
I'm pleased to announce the release of virt-p2v 0.9.7. This is a substantial rewrite mainly to improve the user interface and internally to lay the groundwork for supporting V2P and partition resizing. Source, ISO image and PXE boot image available from: http://et.redhat.com/~rjones/virt-p2v/ http://et.redhat.com/~rjones/virt-p2v/download.html The major changes: - Interface rewritten to use Newt text mode windowing toolkit instead of the dialog-based approach which was very proving to be quite limiting. - Much better support for setting up the network and SSH connection. - Fetch and parse capabilities from remote server, to improve the quality of the generated configuration file. In particular, 32-vs-64-bit issues which plagued the older versions are fixed. - Now uses libvirt to contact remote server. - Remove docs, locales to reduce image size. - More accurate memory estimates. - Support local repositories. - Internally: The way configuration data is stored has been rewritten to be simpler to customize and to support V2P. Now understands that i386 = i686. Won't attempt to configure network from a non-RHEL/Fedora root. The source isn't really buildable at the moment without some help because it needs a few packages which aren't in Fedora yet, so if you are trying to build from source please contact me. I also have a branch which can do V2P & (some) partition resizing so if anyone wants to try this please contact me off-list.

It's something like 32 MB in the final, compressed ISO, or about 20% of the total image size.

It happens because I rearranged the way that network config happens, so now it happens earlier. Previously: 1. ask the user every question 2. mount root with snapshot 3. set up network Now: i. ask the user just the network question ii. if configuring network from root, then mount root readonly iii. set up nework iv. unmount root, continue with questions ... v. mount root with snapshot The cardinal rule of p2v is that we must absolutely not modify the original machine, which is why root is mounted readonly in step (ii). But in fact what should happen is that step (ii) should mount root with snapshots, and then we leave it mounted and don't ask the user to select the root again in this case.

[Please CC replies to et-mgmt-list] Attached is an example CSV file from the latest version of virt-top so we have something in common to talk about. Load this into a spreadsheet program like OpenOffice Calc. The basic problem with CSV is that it's a 2D file format, and if you have more dimensions than two in your data, as in this case, you have to squeeze them into two somehow. This is what I'm doing here. The data format is: [common columns] [domain columns] time[dom1] [dom2] [dom3] | | V Looking at the spreadsheet, columns A-Q are the common columns. Column R is the first domain column. Note the title "Domain ID". This title always marks the first domain column. Column Y is the last domain column for the first domain. Note that it is the last column that has a title, and this is how you detect it. Column Z is the first domain column for the second domain. It contains the domain ID of the second domain. The second domain goes through columns Z - AG. If there was a third domain it would start at column AH (which would be its domain ID), and so on. You can work out the width of each domain as Y-R (8 columns in this instance, but you have to calculate it because it might be different in future versions of virt-top, or even in current versions of virt-top if you use the --no-csv-* command line flags). BTW, which Python library are you using to parse CSV? You should always use a library. You can't get away with just splitting at comma characters. If you have the ocaml-csv module installed from Fedora then there's a command-line tool called csvtool included which can also do some manipulations of CSV files correctly.

It's pretty robust at the moment. The rule is that the CD does not make any changes to the source system at all. HOWEVER, mistakes are always possible, hence the advice to keep a backup. In reality the worst it is likely to do is to corrupt your /etc/fstab file, and there will be a backup in /etc/fstab.p2vsaved. In the future we'll be doing more modifications during the migration, eg. installing new kernels, kernel drivers, resizing partitions, and at that point the opportunity for failure becomes more drastic. > Does the destination server need to be an active XenServer? > Can/does your implementation create the virtual image on the > destination server? Can the destination server be any server > accessible through ssh that has disk space? No, the destination does not need to be a Xen server. Yes, you can transfer to any staging server reachable by ssh. Currently if you do this you'll get slightly reduced functionality -- you may need to make some edits to the config file by hand because we rely on contacting the Xen server to find out how it is configured (eg. is it 32 or 64 bit -- the configuration file is different under these circumstances). In future if we can contact the final server we will be able to do things like automatically bringing up the virtual server, but we will always have a fallback mode for people like yourself who want to use a staging server. Note that you can also transfer to non-Xen hypervisors like Linux KVM.

[et-mgmt-tools] ANNOUNCE: virt-df ('df' for guests) now supports LVM
I'm happy to say that virt-df, the command-line 'df'-like tool for looking at disk usage of guests, now supports LVM, making it usable for the majority of situations where your guests are running Linux distributions. You can now run 'virt-df' on the host and display the disk space used/available on all filesystems of all your guests. There is no need to run anything inside the guest. Here is an example with two running domains: # virt-df -c qemu:///system -h Filesystem Size Used Available Type rhel51x32kvm:hda1 96.8 MiB 14.6 MiB 82.2 MiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol006.4 GiB3.6 GiB2.8 GiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol01 992.0 MiB Linux swap rhel51x64kvm:hda1 96.8 MiB 22.1 MiB 74.7 MiB Linux ext2/3 rhel51x64kvm:VolGroup00/LogVol006.4 GiB3.2 GiB3.2 GiB Linux ext2/3 rhel51x64kvm:VolGroup00/LogVol01 992.0 MiB Linux swap Home page: http://et.redhat.com/~rjones/virt-df/ Source and binaries from: http://et.redhat.com/~rjones/virt-df/files/ Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-p2v converts physical machines to virtual machines.

XML is fine for people who never learned how to use lex & yacc. Two large anti-patterns in this area are XSLT (a programming language) and Ant (a Makefile-type tool). Compare XSLT to CDuce (XSLT done right) and Ant to plain Makefiles.

It's plainly ridiculous to create a whole new editor just for editing a particular form of file. This editor you're going to write is going to be better than vi & emacs?

Are you planning > to support the funky QCow / VMDK formats too ? Yes, interesting point. Since I always use flat files or straight partitions for my guests I admit I hadn't given this much thought :-) However support for these formats is just a matter of decoding enough of the structure to enable the same mappings to be made in the 'virt-df' library, same as for LVM2 or indeed MBR partitions now. I'll take a look at it.

For MBR & LVM once you've parsed the partition tables / LVM metadata, then the information you need just falls out naturally. For NTFS & DOS FAT (you won't believe it but ...) you need to find the allocation bitmaps/tables in both cases in order to calculate blocks used/free for df anyway. For ext2 it's a little bit more tricky because one needs to additionally parse the group block free bitmaps [this bit doesn't work at the moment, but is in principle very simple to add].

There are a number of reasons why this might not work.
Libvirt over SSH requires passwordless logins (eg. using ssh agent).
It also needs a netcat ("nc") program available on the remote side and
the netcat program has to support UDP sockets -- this isn't true on
Debian for example.
Take a look at the virt-manager log file (in /root/.virt-manager) for
more clues and also tell us what versions and operating systems you're
actually running.

We couldn't get that working on Windows because the Python stuff for Win32 was too complicated. This is a port of virt-ctrl instead (http://et.redhat.com/~rjones/virt-ctrl/) which is a far less powerful virt-manager clone that I wrote in my spare time, just as an experiment. (It's also a rather old version of virt-ctrl. I really must update that package ...) Anyway, you should be able to set up your Xen hosts so that TCP (insecure) connections are possible. Assuming that libvirtd is running, there should be a file /etc/libvirt/libvirtd.conf which you can edit to enable TCP connections: http://libvirt.org/remote.html#Remote_libvirtd_configuration listen_tcp = 1 I believe you also need to edit /etc/sysconfig/libvirtd and uncomment: LIBVIRTD_ARGS="--listen" and of course open firewall port 16509 if necessary. Then you should be able to connect remotely using this URI: xen+tcp://hostname/ TCP connections are totally insecure, so you should only do this on a private network.

[et-mgmt-tools] ANNOUNCE: virt-mem: tools for monitoring virtual machines
I'm pleased to announce this very early pre-alpha release of a further set of tools for monitoring virtual machines. The idea is to provide simple commands which can be run outside the virtual machine to monitor its status. These commands don't require you to log in to the virtual machine, or to install any software, since they work entirely by snooping. So they could be very useful for analyzing guests which are stuck / unresponsive / heavily loaded. Done so far: virt-unamelike uname(1), print guest's system information virt-dmesglike dmesg(1), print guest's kernel messages Coming soon: virt-ps like ps(1), lists processes virt-free like free(1), lists free memory and swap If virt-ps works out, I might do a 'top'-like command, although of course I can't call it virt-top. I'm open to other suggestions too.

The free Xen tools only show you the total memory being used by the guest -- equivalent to the amount of RAM installed in the (virtual) machine. They don't tell you how much memory is being used by processes, in swap or in disk buffers. That is my eventual aim with virt-free (part of the virt-mem toolset).

[et-mgmt-tools] [ANNOUNCE] virt-mem tools version 0.2.8 released
I'm pleased to announce the latest release of the virt-mem tools, version 0.2.8. These are tools for system administrators which let you find things like kernel messages, process lists and network information of your guests. For example: virt-uname 'uname' command, shows OS version, architecture, etc. virt-dmesg 'dmesg' command, shows kernel messages virt-ps 'ps' command, shows process list Nothing needs to be installed in the guest for this to work, and the tools are specifically designed to allow easy scripting and integration with databases and monitoring systems. Source is available from the web page here: http://et.redhat.com/~rjones/virt-mem/ The latest version (0.2.8) reworks the internals substantially so that we have direct access to basically any kernel structure, and this will allow us to quickly add the remaining features that people have asked for (memory usage information, lists of network interfaces and so on). As usual, patches, feedback, suggestions etc. are very welcome! Binaries will be available in Fedora 10 (Rawhide) at some point soon.

No libvirt required for that, _but_ to see any interesting stuff you'd need to capture the entire guest memory which could obviously be quite large. You could do 'virt-mem capture' which captures just the bits of memory that contain interesting data, and that reduces the amount of data you need to capture substantially. Unfortunately I broke 'virt-mem capture' in the latest release by accident, and in any case it requires libvirt to do the capturing. I think the message here is, install libvirt & be happy :-) Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines.

[et-mgmt-tools] [PATCH 5/5] "Launch virt-viewer" (new) browser plugin.
"Launch virt-viewer" (new) browser plugin.
- Based on npshell from xulrunner 1.9.0.
- Includes test page.
The file 'npunix.c' is pretty much identical to what is in xulrunner
1.9.0, except that I made a few const-correctness fixes.
The file 'npshell.c' is only minimally modified from what is in
xulrunner, just changed so that it calls the new plugin entry points.
The interesting stuff happens in 'launcher_plugin.c' and 'test.html'.
The easiest way to test this is:
./autogen.sh --enable-plugin
make
cp plugin/virt-viewer-plugin.so ~/.mozilla/plugins/
firefox `pwd`/plugin/test.html

The configuration format is documented here: http://libvirt.org/formatdomain.html You can also print out the configuration from any existing guest using 'virsh dumpxml ' if you need examples. I'm intrigued by what your Perl management script needed that isn't exposed by libvirt. Libvirt deliberately doesn't expose the full feature set of any one hypervisor which it supports, but instead exposes common features. The reason for this is so that you can switch hypervisor technologies later on. Clearly, we all love KVM, but people have different needs from hypervisors and KVM won't fit all of them. For example, lightweight container-based approaches are better for some virtualization problems (particularly where you really need to run 100s or 1000s of guests on a single machine), and people will still be running Xen and VMWare for many years to come.

Judging by one private reply I got, I don't want this to be misinterpreted. Libvirt DOESN'T expose the minimum subset of all hypervisors (because that would be very small and useless). It exposes general virtualization features, even if those features only apply to one or two hypervisors. For example: migration - only works with Xen & KVM, but could be applicable to other hypervisors in the future when we support them and they support migration scheduler tuning - only for Xen, but generally applicable adding/dropping interfaces from live guests - a general feature supported by many but not all of the backends Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones Read my OCaml programming blog: http://camltastic.blogspot.com/ Fedora now supports 60 OCaml packages (the OPEN alternative to F#) http://cocan.org/getting_started_with_ocaml_on_red_hat_and_fedora ___ et-mgmt-tools mailing list et-mgmt-tools@redhat.com https://www.redhat.com/mailman/listinfo/et-mgmt-tools

You should give /usr/lib64 as the path. As for why it doesn't work, though, I'm really very confused.

[et-mgmt-tools] ANNOUNCE: virt-what 1.0 - a shell script to detect if you are running in a virtual machine
I'm pleased to announce the first release of 'virt-what', which is a simple shell script that detects if you are running inside a virtual machine, and prints some "facts" about that virtual machine. This is a frequently requested feature. Home page:http://et.redhat.com/~rjones/virt-what/ Source and RPMs: http://et.redhat.com/~rjones/virt-what/files/ So far we can detect: - Xen - QEMU and KVM (but not distinguish between them) - VMware - Microsoft VirtualPC I'm hoping that people who run or develop other virtualization technology will be able to contribute snippets to detect those. It's worth saying (before Dan Berrange says it anyway) that although people often think they need this sort of feature, in most cases using this script is the WRONG THING. If you need a specific virtualization feature, then add code to your application to detect that feature. eg. If you need to make Xen hypervisor calls, your application should try to open /proc/xen/privcmd. As Dan once put it: A shell script just printing out 'native', 'dom0' or 'domU' is too simplistic to be broadly useful to management applications. The concepts are also ill-defined, eg 'native' as a concept can be a baremetal kernel, or a fully-virtualized guest, or both. 'DomU' does not distinguish full or paravirt. The distinction of 'dom0' vs 'native' is irrelevant in non-Xen virtualization systems (eg KVM).

[et-mgmt-tools] ANNOUNCE: virt-inspector
Hi, I'm pleased to announce the first 'really working' version of virt-inspector. Source is in the libguestfs source repository: http://git.et.redhat.com/?p=libguestfs.git;a=summary Binaries are in Koji for Fedora 11 / Rawhide: http://koji.fedoraproject.org/koji/buildinfo?buildID=102697 (minimum version 1.0.27 required) This is a tool based around libguestfs which can inspect a virtual machine disk image and tell you some interesting things about what's inside it. Some of the things it can tell you: - What operating system(s) are installed, and what distros and versions. It currently covers RHEL releases, Fedora releases, Debian releases, and has limited support for Windows. - How disk partitions are expected to be mounted (eg. /dev/sda1 -> /boot) - What applications are installed. - What kernel(s) are installed. - What kernel modules are installed. It can produce output in plain text (as a report) or in XML (to feed into other programs). It uses libvirt (if available) to get details of inactive domains, or you can run it directly on disk images. Usage is simple: virt-inspector --xml domain > info.xml # xml report virt-inspector /path/to/disk.img | less # plain text report You can also use it as a wrapper for guestfish, so it mounts the guest disks in the correct places, eg: $ virt-inspector --fish /dev/Guests/CentOS5.img guestfish -a /dev/Guests/CentOS5.img -m /dev/VolGroup00/LogVol00:/ -m /dev/sda1:/boot $ eval `virt-inspector --fish /dev/Guests/CentOS5.img` Welcome to guestfish, the libguestfs filesystem interactive shell for editing virtual machine filesystems.

[et-mgmt-tools] ANNOUNCE: libguestfs 1.0.41 released
[This is the only time I'll send this announcement to qemu-devel] I'm pleased to announce the release of a new stable version of libguestfs, the library for accessing and modifying virtual machine disk images. Based on around qemu and Linux kernel code, this can be used as a library or from scripts to make batch configuration changes to guests, view and edit config files inside guests, and much more. http://et.redhat.com/~rjones/libguestfs/ Source: http://et.redhat.com/~rjones/libguestfs/files/libguestfs-1.0.41.tar.gz Fedora 11+ packages: (Available soon in F11 updates-testing or directly from Koji: http://koji.fedoraproject.org/koji/buildinfo?buildID=104824) RHEL/CentOS 5 packages: (Being uploaded to EPEL now, available soon) Debian packages: http://www.annexia.org/tmp/debian/ Since the last announcement, many bugs have been fixed and features added. The main highlights are: - squashfs and cramfs support - better support for read-only access to drives - many problems with string handling in different language bindings have been fixed - internationalization support - ext4 support improved on RHEL 5 - improved support for running commands in the guest - support for skipping tests - lvresize and ext2/3 resize support - pvremove, vgremove, lvremove commands - sleep command - IRC channel #libguestfs on FreeNode Bugs fixed: 501761 - libguestfs requires qemu, not qemu-system-x86 or qemu-system-ppc 501878 - guestfish built-in commands like 'alloc' and 'help' don't autocomplete 501883 - javadoc messed up in libguestfs java documentation 501885 - Doesn't detect missing Java, --with-java-home=no should not be needed 501892 - OptString parameters not handled properly in bindings 502309 - libguestfs build failure - tests occasionally fail with 'ranlib: './libmlguestfs.a': No such file' 502533 - Polish translation of libguestfs 503133 - "mkdir-p" should not throw errors on preexisting directories 503135 - cramfs and squashfs modules should be available in libguestfs appliances 503169 - libguestfs /dev is too sparse for kernel installation/upgrade Thanks to Charles Duffy for a number of patches and suggestions.

There's a (little) overlap and a possible user in virt-inspector.
In virt-inspector we do things the other way around - we look inside
the guest for files like /etc/redhat-release and /etc/debian_version,
and parse those to determine the OS distro and release (also we parse
the registry to do the same for Windows). The code for Linux is here:
http://git.et.redhat.com/?p=libguestfs.git;a=blob;f=inspector/virt-inspector.pl;h=1d8a84b424eb73ceafee041f0e1d76d371506aa7;hb=HEAD#l410
It would be nice for virt-inspector to output ID strings which are
compatible with osinfo.

[et-mgmt-tools] F12 feature: Host information
I posted this page on the wiki last week, which is a feature we intend to implement for Fedora 12: http://fedoraproject.org/wiki/Features/Hostinfo Any comments? Rich. "Allow a virtual machine to see information and statistics from the host operating system, under narrow and strictly controlled conditions and only at the discretion of the host administrator. Detailed Description Allow a virtual machine to look at host information (such as number of physical, not just virtual CPUs), and statistics like the load on the host. Users have asked for this primarily as a diagnostic tool -- for example, poor performance of a virtual machine might be caused by excessive load on the host. Normally we try to isolate virtual machines from accessing any such details from the host, and there are very good reasons for that too, such as security of the host, commercial confidentiality, and the privacy of other virtual machines running on the host. As a result, at the moment there is no mechanism for accessing host information. We propose to add a feature which allows the host administrator, at their discretion, and only of limited data to limited virtual machines, to export host information and statistics to virtual machines. Administrators will need to: * explicitly enable this feature, * select the virtual machines and/or data they wish to be seen in guests, * select the frequency that guests can ask for data. The mechanism will be a daemon running on the host which collects the statistics (see below for what). The information will be exported to guests over a spare (virtual) serial port or through the qemu/kvm vmchannel feature, whichever is available. Guests will request information by sending a plain text command to the serial port, and will receive information in the form of a simple, plain text message. No special drivers or software are required by the guest. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones New in Fedora 11: Fedora Windows cross-compiler.

Yes this is good. I've actually been playing with manual migration of guests from VMWare recently. This is what I do: (1) Export the guest in OVF format (File -> Export -> Export OVF Template) (2) Convert the *.vmdk file (disk image) into a raw file: qemu-img convert -f vmdk -O raw *.vmdk image.raw (3) Boot the raw image using libvirt. I create a libvirt configuration by hand, but IIRC there is now a tool which does this automatically. Some problems: VMWare tools should be uninstalled from the original guest. Virtio drivers should be installed in the new guest (this is very complex to do for existing guests, which is why we are writing the virt-v2v tool to automate it). The virt-v2v tool will be ready in a few weeks.
