Xen vs. KVM on Debian squeeze
Hi, I'd like to set up virtualization on a home server with a Debian GNU/Linux squeeze amd64 host and squeeze and wheezy amd64 guests. I'm trying to decide between Xen 4.0 (with paravirtualized guests and probably the xend/xm toolstack) and qemu-kvm 0.12 or 1.1 (with the libvirt tools). My experience in this area is currently limited; I've only used qemu-kvm 0.12, and only through Virtual Machine Manager. So I'm looking for some advice and answers to help me decide how to set this up. The server has two 3.0-GHz CPU cores (an AMD CPU with the AMD-V/SVM virtualization extensions) and 2.0 GiB of RAM (which I'm planning to either double or triple). I'd like to run at least five guest systems to build software, manage mailing lists, serve files, manage a RAID 5 array using md, etc. So I need a virtualization infrastructure that offers efficient CPU and I/O virtualization and allows guest systems to gain or forfeit virtual memory as their loads require (pooling my limited RAM as efficiently as possible). (Ease of understanding and maintenance are nice as well, though I'm happy to read documentation.) I see that KVM supports a rather simple method of overcommitting memory [1], relying on Linux's lazy page allocation and swapping [2][3]. [1]: http://www.linux-kvm.org/page/FAQ#Is_dynamic_memory_management_for_guests_supported.3F [2]: http://www.linux-kvm.org/page/Memory [3]: https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Administration_Guide/sect-Virtualization-Tips_and_tricks-Overcommitting_with_KVM.html I'm not sure I like the idea of "freeing" memory by swapping, but at least it's a simple design and easy to set up. Is there a newer method in KVM (in Debian squeeze or squeeze-backports) of automatically growing and shrinking guest systems' virtual memory space in RAM, preferably without using swap? Xen used to have a userspace self-ballooning daemon called "xenballoond" [4], but it's no longer maintained [5] and it supposedly only supports Red Hat–family systems [6]. [4]: http://blog.xen.org/index.php/2008/08/27/xen-33-feature-memory-overcommit/ [5]: http://old-list-archives.xen.org/archives/html/xen-devel/2011-02/msg01333.html [6]: http://xenbits.xen.org/hg/xen-unstable.hg/file/91232efdcfdc/tools/xenballoon/xenballoond.README Now Xen supports "Transcendent Memory" or "tmem" (self-ballooning and frontswap self-shrinking) [7][8] instead. [7]: https://lwn.net/Articles/454795/ [8]: drivers/xen/xen-selfballoon.c in Linux 3.1 or later The tmem code is in the version of Linux in squeeze-backports, and the XEN_BALLOON option is enabled. But, as far as I can tell, CLEANCACHE, XEN_SELFBALLOONING, and FRONTSWAP are disabled. I'd rather not have to rebuild the Linux packages to install in my squeeze and wheezy domUs for this. All things considered, I'm leaning slightly toward qemu-kvm, because it looks like it'll do what I need in a simple and familiar way; but I'm concerned about the performance of the CPU and I/O virtualization and the page swapping. Can anyone show me that I've overlooked something about Xen in Debian or convince me that qemu-kvm will perform fine for my needs? Thanks, -- P. J.

how to tell webalizer where webalizer.conf is?
if i might impose on the list one more time, this has to do with still tweaking the migration i did once upon a time, and is webalizer-specific, but i'm betting someone here is going to see what i missed doing in about five seconds. it came to my attention that the web site stats generated by webalizer for this system simply *stop* at sept 20. all these stats were being generated in the directory /var/www//logs and, sure enough, if i pop into that directory, i can see all the usage files, and they clearly stop at that date. so, obviously, as i was doing the migration, i failed to re-tweak the output directory for webalizer. i checked the default(?) /etc/webalizer/webalizer.conf file and, sure enough, rather than pointing to that long-time output directory, it was pointing at /var/www/webalizer, and when i ran the cron webalizer script manually, it dumped its current output in that latter directory. ok, easy enough, i just have to correct the entries in /etc/webalizer/webalizer.conf. but i looked closer in that logs directory and i can see a webalizer.conf file *there* as well. with the *correct* values for those variables. so it looks like the person who set this up chose to keep the .conf file with the log files, and not in what i thought was the standard location. is that a reasonable thing to do? because it would certainly break the webalizer cron script, which looks in the /etc location by default. is there a webalizer-approved way to have it start off with a different location for its .conf file with manually hacking the script itself? i'd like to avoid that if i could. rday p.s. i could also just make the changes to the standard file /etc/webalizer/webalizer.conf, but if the previous admin chose to keep that conf file in the logs directory, i might as well stay consistent. ==== Robert P.

how to downgrade and pin package (durep)?
as a followup to an earlier post of mine, i can see now that the current durep package (0.9-1) works *very* differently from the earlier one, so rather than fight with the new one, i'm happy to use the older version. how exactly does one downgrade a package to a particular version, then make sure it stays there over upgrades? thanks, i've been awake for a day and a half and i'm just too tired to go looking for the answer. sorry. rday -- ======== Robert P.

fixed "durep" utility??
i just now ran into this: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482061 is there a fixed version of that? "aptitude update" shows nothing, and that seems like a fairly major error, given that it prevents the program from working at all. or i could just patch it as above and carry on. rday p.s. i've got sources.list configured to use only lenny, so it's possible that there's a fixed version in testing. -- ======== Robert P.

(even if it makes some people wince. :-) rday p.s. curiously, on the new system waiting for all that migrating data, /var/lib/mysql has three entries that don't exist on the current system: ibdata1 ib_logfile0 ib_logfile1 not sure what those are, but they're sizable. maybe i *will* do the dump/restore thing, just to play it safe after all. -- Robert P.

how to renew a security certificate?
i'm hoping this is an easy one, even though i'm going thru the docs as we speak. on a functioning debian system, for the last many weeks, the clients who have fired up their thunderbird clients have been told: "mail.XXX.com is a site that uses a security certificate to encrypt data during transmission, but its certificate expired on 7/7/2009 2:06PM" mail is still being delivered, though, but it would be nice to make that diagnostic go away. i have a screen cap of the dialog box, which makes it clear it's related to dovecot. is there a simple recipe for renewing that cert (something i've never had occasion to do)? just pointing me at the appropriate web page would be fine. and is that enough info to know how to solve the problem? an expert mail admin i'm not. rday p.s. i'm assuming the certs are kept under /etc/ssl/certs. is there a cert examination command to display things like expiration dates, that would let me poke at some of those .pem files and go, "aha, that's the one with that expiration date." -- ======== Robert P.

lenny migration, part 4,862: samba
still playing it safe and appreciating the feedback just so i don't do anything dumb, i'm now copying over the data/config related to the samba setup from the old server to the new server (in preparation for the eventual switch) and, as i read it, i just have to synchronize the following: /etc/cron.daily/samba /etc/logrotate.d/samba /etc/pam.d/samba /etc/dhcp3/dhclient-enter-hooks.d/samba /etc/samba/* that last entry meaning, of course, all the relevant files under /etc/samba. am i missing anything (other than the directories themselves to be shared, but that's going to be part of another massive copy operation). are there any other *config* files that i need to sync up to make the samba setup identical? thanks. rday p.s. i just noticed that the new server has /etc/samba/dhcp.conf, but the old one doesn't. i conclude that i made that selection when i installed samba but, since it's not on the old server, i just figure i'll delete it so everything matches exactly. -- ======== Robert P.

[OT?] "5.7.1 relay access denied, please check the message recipient and try again."
ok, if i can impose on the list yet again (for something that doesn't appear to be something *i* did for a change), a fully-updated lenny mail server suddenly started to generate the above error when its corporate users try to send email from home through that mail server. i've been assured that that was working for a long, long time and only went south just over a week ago. and since i've also been assured that it affected everyone simultaneously, i'm concluding that it's a server issue. the system is using postfix and, to the best of my knowledge, *i* wasn't messing with the mail system when it broke so i'm guessing someone else was doing some configuration. i've found a number of web pages referring to that error and i'm perusing them right now, but if anyone has any hints, i'm listening. a couple more things. i have a backup copy of the entire /etc directory from before the breakage so i can quickly diff any relevant files (/etc/postfix/main.cf appears to be unchanged). also, any attempts to try to email from outside the internal network *appears* to coincide with the following messages in /var/log/mail.warn: Sep 15 23:12:38 main postfix/smtpd[20633]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory Sep 15 23:12:38 main postfix/smtpd[20633]: warning: SASL authentication failure: Password verification failed Sep 15 23:12:38 main postfix/smtpd[20633]: warning: unknown[24.114.232.37]: SASL PLAIN authentication failed: generic failure but i've verified that saslauthd is running. so ... is there something trivially obvious that would have changed on the server side that could cause this? i'll take everyone's word here that they haven't messed with their t-bird settings, so i'm looking at what on the server might have been tweaked. thanks. rday -- ======== Robert P.

where are these boundaries defined? i'm familiar with such values
being defined in places like /etc/default/{login,useradd, ???). from
looking at /etc/passwd and from what you're written above,
* UIDs of < 100 and 65534 (nobody) are fixed and immutable
* UIDs of [100-999] represent packages/daemons that are given
out as necessary as packages are installed so they don't have
to match and i should leave them as is
* UIDs of 1000 and up are for manually-created accounts, and i
*should* reproduce them exactly from the old system to the
new system
seems pretty straightforward, much like i've seen on other linux
systems.

right, see my previous post. i already have the new running system,
so i don't want to overwrite install or log information with content
from the *old* system. (is it just me, or does anyone else think that
/var has gotten a bit chaotic in that respect?)

that's sort of the idea i had in mind, but not quite that
brute-force. after some reflection, i'm willing to spend a little
more time migrating stuff over subsystem by subsystem, just to give me
the chance to see how those things fit together.
for example, obviously i'm going to (mindlessly) copy over all of
/home, but for that to make sense, i'll need to reproduce the
/etc/{passwd,group,shadow} files, plus perhaps /etc/profile and
related files, and anything that was added to the PAM subsystem
regarding user settings. it's a bit more work, but it would be more
educational. so, in that specific case, i'd be interested in all of
the files that contain any information related to users and groups.
regarding /var, i wouldn't want to copy over all of it since i have
no interest in all the log files, which wouldn't be relevant to the
new system. so i'd have to be more selective. but i *would* want to
copy over anything under /var that *would* reflect any configuration
or data.
a question about mysql. i want to reproduce all the mysql databases
on the new system. is it sufficient to copy all of /var/lib/mysql?
is that where the databases are physically stored? as opposed to
doing mysql dumps and restores?
anyway, that's what i'm thinking -- one subsystem or component at a
time, so i can appreciate the distinctions between all the parts. ftp
server. mail server. web server and configuration.
good idea? too much work? thoughts?

"dd" would not be a good choice as i already *have* the fundamental system set up in terms of software. all that's left is to copy over the additional *configuration* and *data* represented by the old system, for which dd would be a very bad choice, indeed. "cpio" is a better choice, but the decisions to be made there would be *which* files and directories to copy to reproduce the old system in its entirety as a mail server, web server, ftp server and so on. rday p.s. i don't want to sound a bit short, but there seems to be an annoying pattern on this mailing list that people don't actually *read* the question i'm asking before attempting to answer it. to recap, the new (64-bit) server has been installed with lenny (5.0.3, in fact). it's bootable, grub is fine, it's been set up with LVM. in short, it's a perfectly respectable and running 64-bit system. what i'm after are any potential tools that assist me in migrating the config and data info from an existing (32-bit) server. and since pretty much all the software is installed, the difference in bit size shouldn't make a big difference in what's left to be migrated, given that what's left is primarily data. -- Robert P.

why can't i use grub with an ext3 /boot partition?
possibly related to an earlier post that discussed grub but, when installing lenny, if i choose to create a separate, primary partition for /boot (a long-time habit), if i select ext3 for that partition, i am not offered the chance to use grub as a bootloader. as best i can tell, that /boot partition must be both: 1) set as bootable, and 2) ext2 format otherwise, i'm stuck with lilo. is this true? is there a reason the debian install can't handle grub and a bootable ext3 partition? i've tested this a number of times and it seems that ext3 is the deciding factor. rday -- ======== Robert P.

saving package info for a fresh reinstall
hi, i want to save all my package info off to the side and do a re-install of lenny so i can restructure my logical volumes. (i realize i can do that manually with the various lvm commands but given how much i want to move things around, and that this install is still on a new server which isn't being used yet so i have no data to save, it's just easier to reinstall). i can see the idea of using dpkg with --get-selections and --set-selections, and googling showed me this: http://sunoano.name/ws/public_xhtml/debian_notes_cheat_sheets.html#get_and_or_set_list%20_of_installed_packages but as i read that, i saw references to the two commands: debconf-get-selections debconf-set-selections yet i see only the first of those two on this system (the set variation). that seems odd -- i can't find the first one. am i missing something obvious? in any event, if i have little configuration information to preserve, what's the simplest recipe to save my pkg info, then restore it after a really basic fresh install? thanks. rday -- ==== Robert P.

apparently, lenny, apache 1.3 and php5 is a bad combination
i was hoping to continue running apache 1.3 on my new lenny system, just until i could make sure i had a clean upgrade path, then make the switch to apache2. but it seems like i won't have that option since i'm running some apps (eg., horde) which now fails to make a mysql DB connection, and that's because the php4-mysql package was removed to make way for php5-mysql, but apache 1.3 currently has only php4 support. i did notice that there's a "libapache-mod-php5" package that is supposed to add php5 support to apache1, but trying to install that tells me that that package is "BROKEN", and that libapache-mod-php4 would be removed. which doesn't do me much good. is there a way to just add php5 support to apache 1.3 so i can get horde up and running again, or should i just bite the bullet and do what it takes to switch to apache2?

"deborphan" is a wonderful utility
much thanks to whoever suggested "deborphan" recently to help me clean out unused libraries. i've been fairly conservative with it, getting rid of libs a bit at a time and making sure things still run. someone else locally suggested to just throw caution to the winds and run: # aptitude purge $(deborphan) in fact, run it until it stopped making a difference. is there any way that can cause problems? theoretically, i can see that it shouldn't cause any breakage. but i was curious when i noticed that "libhal1" on this etch system is listed as an orphan. coming from a fedora universe, i always thought of the HAL layer as fairly fundamental, but i guess i've stripped this server down far enough that even the HAL library isn't being used anymore. so is removing orphaned libs in bulk a safe thing to do? it would *seem* to be but i just want to be sure. thanks. a couple more questions coming shortly. rday p.s. starting with a server that had just over 600 packages, i'm now down to 460, with no loss in functionality. hopefully, this will make that final upgrade as safe as possible. p.p.s. i'm starting to like this debian thing more and more. :-) -- ======== Robert P.

a pseudo-"clone" facility for migrating to new hardware?
into the final stages of my debian upgrade adventure, and here's the final phase. at the moment, i have a couple more upgrade steps to get the existing server (old dell P4 system) up to a fully-upgraded lenny system, and make sure all the software still works properly (web server, mail server, etc.). and this is on a system where there is a single root filesystem (/dev/sda1), so it's a very simple partitioning layout. once that upgrade is done, i want to pick up the entire install, and move it to a new dual-drive poweredge server, obviously keeping everything in place. but i want to format the new system with LVM and multiple filesystems for robustness. so what's the best way to do that? the obvious solution is to take the running server offline, reboot to a rescue CD, and copy the entire rootfs verbatim to a backup device, connect that backup device to the new server, and restore with a directory-oriented restoration which will honour the new LVM layout. but that suggests that the new server already has a debian install on it, so that restoration will obviously end up writing over top of an existing install. is that safe? i find it hard to believe that would work cleanly as the old log files (dpkg, aptitude and so on) would overwrite the ones on the new server, and i'm betting i'd end up with all sorts of inconsistencies. the only way i can think of avoiding that kind of grief would be for me to do the barest install on the new server, where the packages i installed there would be an absolute subset of the ones on the old server. or, better yet, just arrange for empty filesystems to be sitting there, waiting to be filled. is there, perhaps, a utility for this sort of thing? after all, this has to be a fairly common occurrence -- moving a working debian system from an aging, old system to a newer one. thoughts? rday -- ======== Robert P.

should a "normal* system have multiple library versions?
as a followup to something i asked earlier, i was curious about whether it was safe to clean older versions of packages off of a system i'm currently upgrading. (i inherited this system, so i don't have a full history of how it got to be how it is.) more specifically about those packages with multiple versions, most of them are, in fact, library packages. working from memory, there were quite a few lib packages that had two versions installed, a small number with three or more. is that normal? for comparison purposes, i'm looking at a fully-updated lenny system right now, and i see not a single example of a lib package for which multiple versions are installed, which is what i would expect. so i guess the question is, under *normal* circumstances, if one sticks with nothing but the stable packages, and does nothing but normal upgrades, is there *any* reason for a system to end up with multiple versions of packages? particularly library packages? i would have thought that, under normal processing, lib packages and their reverse dependencies would stay in sync as one kept upgrading. are there curcumstances under which that would *not* be the case? because my plan is to, for all of those older lib packages, use "apt-cache rdepends" to see who cares about it and, if no one, purge it. i see no reason to hang onto useless packages, if they are in fact useless. rday -- ======== Robert P.

(how many package management commands and alternatives *are* there in debian? :-) so the question now becomes, if i run that command on both gcc-4.2-base and gcc-4.3-base, it looks like (not surprisingly) the 4.2 package has lots of 4.2-related reverse dependencies, and likewise for gcc-4.3-base. so do i really need the 4.2 stuff? if anyone has a fully-updated *lenny* system and they're willing to run the same commands, is there anything about the output from the 4.2 version that would suggest that it needs to be retained, given that 4.3 is on the system? and on the system i'm upgrading, there are a number of packages that are installed with more than one version. i'd just like to clean that system by purging anything that has no value. rday -- Robert P.

safe to purge older versions of installed software?
this should be an easy one: on my current (etch) system, there are a number of packages that have more than one version installed. for example (and from memory), there are at least three versions of gcc installed. am i safe to remove/purge the older ones? perhaps a better question is, what is the command to list the packages that depend on a certain package? in fedora, i'm used to running: $ rpm -q --whatrequires so i can always ask whether anything depends on one of those older versions first. in particular, i noticed that most of those older versions of installed packages were "lib" packages, so it should be easy(?) to ask whether there's anything installed that needs an older version. if not, i should be ok to get rid of it, no? rday -- ==== Robert P.

"Mounting /root/dev on /dev/.static/dev failed: No such file or directory."
long story short (at least for now): * upgraded sarge to etch, retained 2.4.27 kernel * verified that upgraded system works fine * followed docs to upgrade kernel alone to 2.6.18 (based on etch release notes) * kernel upgrade process seemed to install all the bits and pieces in the right places (/boot, /lib/modules) * boot to new kernel produces: ... lots snipped ... then very similar to what you read here: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/26391 i've googled the daylights out of that, so i'm trying a number of different things, but here's my first question: given that the boot messages fly by so that i have only the final screen of boot output left, are those messages archived anywhere so i can go back and look at them after i get dumped into the initramfs busybox? i'm fairly new to debian, but have lots of background in fedora (for what that's worth). i've been taking notes so i definitely have more questions but for now, i just want a way to see the *entire* boot sequence, since there might be something there that just gives away what the problem is, except that it's already scrolled off the screen. thanks. rday -- ======== Robert P.
