Just FYI: I just had to change it to pc-i440fx-2.11.
I'm on Sid and some libvirt/qemu upgrade seems to have removed 
pc-i440fx-2.0.

This will probably hit you when you upgrade to Trixie.
Unfortunately this time XP wanted a re-activation...

Unless someone can tell me otherwise, my understanding is that VNC as packaged 
in Linux does not support audio.

Hence I have always used Spice for both video and audio.

When I first heard from this thread that Spice was depreciated, I thought it 
was a mistake, but it appears that RedHat is no longer supporting Spice. This 
is bad news if Red Hat does not have a way forward for USB redirection, video 
and audio.

I hope this issue (mainly H.264 codecs ?) is resolved soon. Spice seemed to be 
the way of the future.

Below are a few links which talk about this change:

https://access.redhat.com/solutions/5414901
Spice protocol is being deprecated in RHEL 8.3 
Spice remote display protocol is being deprecated in RHEL8.3 and will be 
removed in RHEL9.

https://forums.rockylinux.org/t/spice-support-was-dropped-in-rhel-9/6753
Why no SPICE:

Due to some license restrictions around H.264 codecs we are not able to 
provide a Streaming solution which is needed for modern workloads (as all 
drivers are using 3D today). Also vGPU support is not possible without this.
There are quite some 3rd party solutions that already have a proper 
implementation (licensed software due to H.264 restrictions unfortunately).
For console access and local acceleration VNC is capable of doing the job - 
and VNC is also used for OpenStack and KubeVirt and they are both not 
interested in using SPICE instead.

Mainly due to (1) and (3) we decided to deprecate our work on SPICE.


https://www.reddit.com/r/kvm/comments/wa9lxm/rhel_9_spice_alternative/
The reason is some licencing issues. I hope Fedora won't follow, as my 
workstation is all VM. 
...
would it be faster to install Xrdp or similar in the guest and use that? That 
seems to be the solution RedHat is suggesting.

I still use spice (remote-viewer from virt-viewer) for Linux guests on

have seen notices that it is deprecated though.

Thanks everyone. The exact solution was provided by Detlef - change the 
machine type to pc-i440fx-2.0. However, that is easier said than done as 
Timothy's advice about editing the XML from within virt-manager didn't 
work. For some reason it complained about the machine type when I tried. 
I had to remote into the server to use virsh edit  to actually 
make the change. Along the way, I found another issue on one of the 
machines - spice was no longer supported either - that shows how long 
it's been since I last used them.

When dealing with legacy OS like WinXP I prefer to be on a safe side and 
choose older module, which emulates a chipset from Pentium I era.

So guest OS won't freak out and will install drivers automatically.
It also matters if OS was previously installed on that specific 
virtualized hardware, otherwise it will boot into BSoD.

Older OS can't handle properly these, basically, "motherboard swaps".

What are the capabilities of the KVM Host?  I use an Intel i7. 

Can your Host support a SandyBridge CPU, if you create a new VM (e.g. try 
creating a SandyBridge CPU configure VM and install Debain Bookworm)?

I expect that you may have other issues in Windows XP itself,  if you do get to 
run Windows XP on different architecture that it was originally installed to 
(which is why my VM uses QEMU to emulate a Sandybrige CPU).

Other than researching links on the topic, like the two below, I am hoping that 
the Virt-Manager VM XML I posted below may give you some ideas.

I believe qemu is important to emulate the older CPU.

You can edit VM (domain) configuration described in xml directly using 
virt-manager.
To make it happen you need to enable this function in Preferences menu ( 
Edit >> Preferences >> Enable XML Editing ).


Now, if you open hardware details of your VM, there will be an extra tab 
called "XML".

Select "Overview" from the hardware list and click on "XML" tab.

Look for a string that looks like this:
hvm

And change it to:
hvm

I fired up an XP VM on a recent windows machine using VirtualBox.

There is VirtualBox for Debian but not in the current release, though it

You then may have the problem of changing the VM format so VirtualBox

Hi,

I have a project that I'd like to work on in a virtual machine hosted on 
my Bookworm system. In the old days (5-10 years ago) I used VirtualBox, 
just from inertia. I haven't really virtualized since then.


What's the current recommendation for someone who just wants to create a 
one-off VM to run Debian under Debian? As this is not my job or even 
main hobby, ideally it should have setup at least as easy as VirtualBox 
was back in the day.


System is an ASUS ExpertCenter PN52 (Ryzen 7 6800, 32 GB of RAM, 2 
terabyte SSD).


I can advice virt-manager, it is like Virtualbox was, but the modules 
are allready in the kernel so don't have to be compiled like with 
Virtualbox. And virt-manager is in Debian, Virtualbox is not in Debian 
so far I know.


Some advices:
You have to add yourself to the group libvirt, something like:
adduser carl libvirt

And it's important to start the virtual network by default:
virsh net-autostart default

To start a virtual machine in one click so without starting virt-manager 
first I make a script like this:


#!/bin/bash
sudo /usr/bin/virsh start win11
virt-manager --connect qemu:///system --show-domain-console "win11"


It seems to be faster when you use another driver for your virtual disk. 
There are many manuals for setting it up. It's not really difficult.

Paul

For sure you can't miss qemu + kvm,they are the most powerful tools for
virtualization. With qemu and kvm you can pass through to the guest OS even
your gpu. With virtualbox or vmware you can't.

They're referring to the machine's hardware BIOS/UEFI configuration.
The very first thing you can access when powering up the machine.
Usually it offers: press some key to access some configuration menu.
Where there's often a facility to enable/disable the CPU virtualisation
feature.

Virtualization anomalies

[paulf]

Folks:

I'm running an Intel Core i3, model 10100. According to Intel's spec
sheet on their site, this CPU has VT-x (virtualization) support. From
what I've read, this shows up in "lscpu" as the "vmx" flag. When I run
lscpu on this chip, that flag doesn't show up. As a result, I can't run
any of the virtualization options (virt-manager, etc.).

(As a point of reference, an older CPU I had in a different machine
(6th gen i5) *did* show this flag when I ran lscpu.)

I'd like to upgrade the CPU to a model which does support
virtualization. But I'm afraid I'll just end up with another chip which
Intel says works with virtualization, and lscpu says doesn't.

Can anyone explain this discrepancy, or provide insights?

QEMU. Your first and last choice for this. If something cannot be
launched in QEMU - it's not worth your time anyway.
Don't go with Virtualbox, it's an Oracle software. Not many people can
stomach *that* unless paid to do it.

It's the same thing. KVM is a variant of QEMU which uses CPU
acceleration for emulated processor instructions.

I suggest installing virt-manager, which is a GUI frontend to libvirt,
which can launch QEMU. While being RedHat and GNOME software at the same
time, it does pretty good job of hiding all those pesky implementation
details.

VirtualBox (mixed FOSS/ proprietary license) works well for my SOHO 
environment:


https://wiki.debian.org/VirtualBox


The GUI makes it easy to create, configure, and operate VM's.  I also 
run VM's headless via the CLI.  I think you can access a VM remote 
desktop with VNC (?).



Debian 9.5 Xfce on VirtualBox is responsive enough for typical office 
productivity and terminal work, but would not be a good choice 
multimedia or gaming.

KVM virtualization with VMM/virt-manager and mouse lag and stutter

[J Mo]

This is one of those I-fixed-it-myself posts where I'm just sharing my 
solution for others, should they google it in the future.


I recently started learning about KVM virtualization. Naturally I 
stumbled across the VMM/virt-manager GTK tool, since that's pretty much 
the only good tool available at the moment (aqemu is promising but not 
good), so I started loading up some Linux live ISO images.


Immediately I had the problem where my mouse was lagging all over the 
place and the experience was horrible!


When I started my VMs manually from the command line with qemu, I 
noticed the mouse lag problem completely went away. Also, later, I 
noticed that the Fedora live ISO images did not have this problem.


VMM forces you to use Spice, even if you are running on the hypervisor 
itself. You have to use either VNC or Spice. You can't start a native 
qemu window like you can do by starting a qemu command manually.


The reason the Fedora Live images worked was because they have the 
spice-vdagent package already installed. The spice-vdagent creates a 
communications channel between the client/viewer host and the 
guest/client host so that mouse movement is smooth, copy-paste/clipboard 
functionality works, and a few other things.


Unfortunately, other than Fedora, none of the other Linux live images I 
tested have this package installed by default: Not Ubuntu, not Mint, not 
Debian, not KDE Neon. OpenSUSE installs it by default, but it's not 
really a live CD. These distros should all fix this if they want people 
to have a good experience when testing under KVM.


And, because these are Live CD images, it's not like I can easily 
install the package and logout/restart, since I have not configured a 
hard drive/permanent storage.


Fortunately, I found a hacky solution in VMM:  Add Hardware --> Input 
--> EvTouch USB Graphics Tablet


Adding a tablet device fixes many of the problems which I experienced 
with VMM, without installing the spice-vdagent on the guest OS.


After finding this solution myself, I also googled and found this post, 
which gives a similar solution to a slightly different problem:


https://serverfault.com/questions/457603/any-way-to-release-focus-on-a-kvm-guest-in-virt-manager-without-having-to-click

So if you use virt-manager and your mouse movement is horribly laggy, 
stuttery, and otherwise intolerable, install spice-vdagent or configure 
VMM to add a non-existent tablet device to the guest.

I would say so. I'm running several kvm machines, and have never had
any problems with stability. As a simple (but quite sufficient)
interface I'd recommend virt-manager to create, clone and operate
virtual machines, I find it just as usable as VMware or Virtualbox.
There are other interfaces that simplify common tasks, but virt-manager
takes care of most of what I need to do.

Also, if there are bugs, I'd expect them to be fixed quickly, as a lot
of (big) organizations depend on kvm. Support for kvm/qemu is also
quite good, there are a lot of people with lots of experience with it
out there.

> say professional virtualization products from VMware or Oracle?

Do you mean "professional" or do you really mean "commercial"? I'd say
kvm meets professional standards.

You could just try it out with a few VM's, and see what you think. It
wouldn't cost you anything, except your time.

My VPS provider (DigitalOcean) relies on kvm for their day-to-day
business, as does many other big names in the industry, so you
shouldn't need to worry about it being inferior to VMware just because
it doesn't come with a pricy licence.

qemu with KVM support compared to "professional" virtualization products from VMware or Oracle

[Martin T]

Hi,

I need to virtualize few dozen virtual-machines for production
environment under Debian host-machine. I like the KISS principle
provided by qemu with KVM support where each utility has its own
specific purpose. For example I set up the virtual switch with
ip/brctl utility or use single qemu executable to crate
virtual-machines. However, is qemu with KVM support as
suitable(stability, reliability) for production environment as so to
say professional virtualization products from VMware or Oracle?


thanks,
Martin

More reasons to use backuppc:

There's a handy web interface.
If the machine to be backed up isn't reachable, it tries again later (1
hour by default).
You can configure blackout periods, so no backups will take place during
certain hours.
You can override the blackout periods based on how old the latest backup
is.
There is an active email support list (backuppc-us...@lists.sourceforge.net).

Don't replicate the VMs. Have separate VMs built using the same configuration.
Use a configuration management solution (e.g. puppet) to define the
configuration of your VMs. Replicate *data* instead.

First, backups are nightly compressed and same files are hardlinked,
so keeping a looong history is not a problem at all (AFA you have
enough free inodes; I's recommend XFS as the reception FS); 2nd,
you can trigger another backup (or restore) whenever you want,
3rd if you have users, they can also trigger a backup/restore when
needed from the http(s) backuppc interface, 4th as backups are
presented as a tree which goes down to the file level, you can
just B/R one file at a time if needed.

@B please ignore my first message i forgot to add the list.

Thanks for the input i really appreciate that. but i have a confusion to
clear. if i use direct rsync and rsync with Backuppc what is the difference?

actually i am asking because i and the software both use same utility then
what is that software can do that i can not. please throw some light on
this issue.

need suggestion on Virtualization backup/DR site.

[Muhammad Yousuf Khan]

Dear All,

we are planning to rent a new server with RAID1 in the cloud and the
purpose of this server will be Qemu KVM virtualization. everything is fine
but the show stopper is Disaster recovery Site.

i think of 4 options and all of them are not upto my requirement and limits.

1st, Option was DRBD but splitbrain on 5Mb link will be a killer.

however, the thing come in my mind to sync only updates/Snapshots to DR
site the way ZFS and BTRFS does. so our second option become ZFS.

2nd option is ZFS and that is a very high in cost as Lots of RAM,SSDs are
involve for ARC1 and 2 so we drop that one.

3rd. option is Btrfs. as it is now Stable but still on back group level or
storage level lots of works still needs to be done. so it fails to gain my
confidence

4th, was Rsync. it can do the trick , it can also send only
updates/snapshots instead of big VMs but it corrupts the VM.

now my mind is empty and nothing is coming inside my mind. can you guys
please suggest anything that can be done to replicate the VMs b/w two
nodes. when both nodes are in different countries.

Thanks
Myk

That's not true. From the virt-install man page:

*format* Image format to be used if creating managed storage. For file
volumes, this can be 'raw', 'qcow2', 'vmdk', etc. See format types in <
http://libvirt.org/storage.html> for possible values. This is often mapped
to the *driver_type* value as well. With libvirt 0.8.3 and later, this
option should be specified if reusing and existing disk image, since
libvirt does not autodetect storage format as it is a potential security
issue. For example, if reusing an existing qcow2 image, you will want to
specify format=qcow2, otherwise the hypervisor may not be able to read your
disk image.
Example vm creation on my local station:
igorc@silverstone:~$ virt-install --connect qemu:///system -n ubuntu08 -r

just learn from some where, that "creating disk with virt-install can only

I think it's mostly six of one and half a dozen of the other. If you are
not using sparse volumes, disk creation can take quite a lot of time, so
it might be logistically easier to batch the creation of a lot of
volumes before you start installing VMs, especially if you need to
re-run the install process a few times as you tweak parameters.

confusion on KVM virtualization (debian admin handbook)

[Muhammad Yousuf Khan]

i have been going through Administration handbook and got confused in KVM
virtualization section.

Book teaches us to create volume first then assign it to vm with
Virt-install command however, we can also create image on runtime with
virt-install command. we do not need volume to be set before creating a VM.
so my question is what is the difference b/w the two methods.
if i create Volume first then assign or if i create image directly from
virt-installl command what are the pros and cons.

Thanks,

Nginx/Apache on OpenBSD runs in chroot. I think it is wise to see how

Run your application as a normal user and the shell's that they will keep 
getting until your developers patch your
application won't matter at all other pissing off the rest of the world with 
their spam/flood/whatever.

That's it for Debian in this thread. The rest is for some php coding list.

The initial attack isn't. Post exploit is. Again, I'd think there are
legal issues with auditing your clients' software making all of this
moot (besides my recommendation for a layer 7 firewall).

For most use cases, see hashcat - not jtr. Also default hash on debian
is ssha per the $6$ in shadow - not md5. See:
http://en.wikipedia.org/wiki/Crypt_%28C%29
It should also be noted - don't use md5 - ever. If you're dealing with
web apps, use bcrypt or scrypt.

Web server and system security is a big subject.
Regardless of the use case a systematic approach is the best, easiest,
and only practically implementable approach. Starting with the Debian
security guide. I've included a link at the bottom of this post.

>>

> 
> As for passwords,

The OP has stated that the server was cracked, not the users application
(though that is likely to have happened). That's consistent with web
shell attack.

It's an injection type attack that runs OS commands[*1]. The web shell
is able to execute a command/commands either as:-
; a result of insecure application or system (php) settings allowing an
uploaded script to be executed directly (file upload)
; unsanitized data - executed php code appended to a link or to file
upload URI

None of those methods are dependent on password access.

The attack can gain elevated permission due to insecure file permissions
or poor passwords. Password insecurity is not the means of ingress (it
is important though - but don't rely on it).

Password security for the server (as distinct from user web
applications) *should* be part of any webserver security. Debian
provides dnsiff and john the ripper which are used in industry best
practice password auditing.
By default Debian implements md5 and shadow which are the 'basis' of
best practice password security (auditing are other practices add to
those things).



As Brad has pointed out, in business we employ specialized personnel to
deal with security (or aspects of it). Please note my point about
security requiring a systemic approach. Paint by numbers and/or ad hoc
"security" is not security.

I'm not sure how your customers may feel about you scanning their apps.
What do you do if you find something they don't want to fix? It will
probably even cause legal issues.

If you do want to do scans, might want to start with someone like nikto
(it's free) and see what you find. Idk how well Nessus does web scans
either - idk that's their core business (I think that would be AD and
compliance). Burp is the tool most use for this. Though, give a baby your
car keys and if you're lucky nothing will happen - if you're not...

A better solution for sites you host and don't own might be a WAF.
Something free like mod_security (some used to sell a rule subscription -
can't remember who). Or a PaloAlto box.

As for passwords, among other things, the company I work for is kinda known
for password auditing so, take it off list if you want a contact for that
type of thing. If you don't own the data though...

The main difference between the jail/container technology and "real" VMs is

It sounds like perhaps you should investigate a web application test suite.
Whether this was running on a physical machine, a VM, or a container, it
would not have changed the result of your php app getting hacked.

Has that problem been rectified?
If not then virtualization won't solve the problems, at best it'll just
restrict the types of problems - you can still find the content hijacked
and traffic redirected.

If user applications can access to OS then you have a permissions
problem - the php application flaw was just the vector.

Your preference *is* how "the big hosters" do things.

The "simplest" way to do things is to install a very basic Debian stable
the use the Virtualmin script to install the rest of the Debian packages
needed for the server. Setup accounts for each user, their applications
will then run in $user/public_html.

It's a trivial attack[*1]) and bad php alone usually is not the cause.

Check php.ini and ensure you haven't accidentally enabled dangerous
configurations e.g. shell_exec, passthru, system etc.  If you *do* have
a compelling reason for enabling those functions consider whitelisting
and input filters. But don't rely on those alone - bad php is often the
cause (don't trust unknown php e.g. user submitted extensions and
plugins for CMS - even when you trust the intentions of the writer
that's no reason to trust the code). Make sure data is sanitized and if
you have a compelling reason to enable OS commands with php consider
wrapping them in java.

If you have allow_url_fopen enabled make sure you have a compelling
reason for it. I've never found one, by my experience far from covers
all use cases.

Ensure that open_basedir is enabled in php.ini

*Double and triple check your webuser permissions*

Test your security:-
As the web user (change /var/www to suit your situation e.g.
$user/public_html)
$
Search_Dir="/var/www";Problems="passthru|shell_exec|system|phpinfo|base64_decode|popen|exec|proc_open|pcntl_exec|python_eval|fopen|fclose|readfile";
grep -RPl --include=*.{php,txt} "($Problems)" $Search_dir

Install and run ClamAV and don't forget that perl may be where the
malware is based.

When you are certain that you system is clean and secure, backup the
static files to a remote location and md5 or pgp them so you can check
them against you web server at a later point to *prove* your system
hasn't been breached.
Then install an IDS.


[*1]can be as simple as weak file permissions or a dodgy cms allowing an
attacker to upload the following


Hope that helps - it's a big question, and so is the answer.
Web applications is a nebulous description, like the information about
your server - so a detailed response is beyond the limits of a post (and
my available time).
I'm glad you asked though instead of making the mistake of looking for a
"silver bullet" solution on a random web page. It's not just irritating
for you when you server gets cracked - it affects all of us.


Kind regards

P.S. Don't forget to check Google Webmaster in case your site/s have
been reported so that you can request the necessary changes.

Re: Security question concerning jail or virtualization

Well Linux has LXC which is supposed to be equivalent to jails (also see
docker). But use whatever suits you.

Idk what's current for breaking out of VMs is. It might be good to pay
attention to who is using the most entropy and make sure you don't run out.
Most VMs use processor VT to isolate things (I don't think any 'jail' does
this).

I think most providers use OpenStack (a suite of technologies). YMMV

I have recently experienced a server being "hacked" due to a security
problem with a PHP application that made it possible for the "hacker" to
gain a web shell.

Due to this experience I would like to know what the best way to limit such
problems is, especially when hosting web servers for users who may or may
not installed unsecure applications on the web server.

What does the big hosters do? What do they use?

The solution can't be too complecated to maintain and I would prefer each
user being completely seperated from the main OS and from other users.

I have been thinking about running Debian inside FreeBSD Jails or "The
Warden". I have also been thinking about using Xen and installing several
Debians on Debian.

What is the best (and if possible simplest) way to deal with this?

Kind regards

You can setup KVM VM through virt-manager and libvirt.

+1 Install it and use it, no reading is needed. OTOH hardware such as
e.g. USB can become an issue. I experienced timing issues with USB, even
with some Oracle special extensions.

VirtualBox is usually a good option. Easy to get, easy to install and 
easy to use.

PS. Sorry for return receipt asking. I am on computer, which I haven't
used in a long time so some Icedove settings are weird.

kvm will work without virtualization, either automatically or using instead 
the qemu executable.  If your hardware supports virtualization, I recommend 
enabling it: without it, kvm will use more CPU time, lower both host and 
guest performance (as I understand it).

I wonder if kvm will work without enabling virtualization option in the BIOS. 
Guest OS performance isn't a priority for me (while host OS is), so I don't 
care about hardware acceleration.

I'm running VBox on Arch with XP SP2 as guest, to be able to use iTunes

Wheezy: Virtualization package recommendations

[T Elcor]

Hi,

I'm looking into running Windows XP as guest on a Debian Wheezy box. The 
hardware is fairly recent (should support virtualization) and Windows XP will 
be used only occasionally, not a production environment, so the goal is to have 
an easy virtualization setup that minimally impacts the host OS (Debian). 

Any ideas? Thanks

Would you mind if they were copied to the official Debian wiki - if I
translated the ones that are only in German you could then copy them
back (if that sounds like a fair trade).

“As long as one person lives in darkness then it seems to be a 
responsibility to tell other people.”

~ Bill Hicks
This how-to collection is dedicated to a variety of topics related to the free 
operating system Debian GNU / Linux. Since I use Debian, both for my own 
projects, as well as for customers, including a variety of servers, I decided 
to discuss a selection of frequently recurring themes and issues, and to 
publish in the form of how-tos and tutorials.

As Debian GNU / Linux does an excellent job on both servers and desktops, I 
have divided this collection of how-tos accordingly.

All tutorials are designed for easy setup, and to provide the required 
knowledge that the system administrator should have in order to understand the 
processes involved. Even if all the howtos have been repeatedly validated, 
there may be some confusing information or mistakes. This is to be expected 
with such a complex collection of howtos and tutorials, so please add comments 
on the relevant pages ;-)

As noted by others (and yourself), many of the works are not in English...

I appreciate that you'd like credit your your work, and possibly create
more visibility for your site - I'd like the howtos in English, and as
much Debian documentation as possible on the Debian site.

Would you mind if they were copied to the official Debian wiki - if I
translated the ones that are only in German you could then copy them
back (if that sounds like a fair trade).

Cheers

more if it were available under something.debian.org
btw where would be the appropriate place for such howtos in the debian

Looks promising, Christoph.  But it appears to be all in German,
even when I click on the UK flag.  After all, this is the English
list (debian-user).  And I don't like advertising on Debian sites,
even unofficial ones.  After all, Debian is a non-profit organization.
(That's why its URL ends in ".org" instead of ".com").

Data consistency is a problem that has to be solved at the application level,
but what I need is a filesystem consistency. Snapshotting filesystem from host
mounted in the guest will leave it a mess. I need to do what lvm in the host
does, which is to tell the filesystem to get synced a frozen into a clean
state and then it probably is possible to make an lvm snapshot from the host
and get a consistent filesystem. I can synchronize database before the fs
freeze.

I know that the kernel can do that but I don't know how to force it from
userspace. lvm snapshot does it automaticaly.

Of course there might be other problems I'm unaware of. I think that online
backups is something that has to work for example in HA environment. You can
hardly provide HA but keep shutting down clusters for consistent backups. What
would otherwise be the point?

I am not aware of any software for doing this (ie backingup VM online with 
appplication level consistency).

In order to minimize the downtime, you may try to save the state of the VM, do 
your LVM snapshot and restore the state. Have a look at virsh man page for 
more details.
But I *don't* think is method will  guarantee application/DB consistency!

well my question was about how to do it without guest shutdown. when I shut
them down it's just a matter of doing an lvm snapshot and rsync the difference
from it to a remote machine.

This is a smilar problem for backups used for a disaster recovery procedure.



I use the following policy:

- Apply defined backup policies to every virtual hosts as they were 
*physical* *hosts*. Id est: incremental backup from monday to friday and full 
backup on weekends.

- The same policy is  applied to the physical host containing 
virtualhosts, but the FS containing virtualhost images are excluded.

- Every month(or very term), the FS containing virtual machine' images 
is 
backed up. Of course, the virtual machines are shutdown during the this 
backup!.To shudown virtual hosts from a prebackup script, you can use 
virsh 
or using directly kvm monitor. Have look at 
http://kerneltrap.org/mailarchive/linux-kvm/2010/1/26/6257297/thread. I've 
posted my shutdown script are there is also a simple script for shutting down 
VM using directly KVM/Qemu's socket.

Of course, you can you use FS snaphosts or KVM snapshosts, but I think 
this is very diffcult to validate FS consitency. 


And do not forget to *validate* your backups during your tests!

HTH,

The problem isn't where to backup but how. the problem is to get consistent
filesystem, consisten data in the filesystem and who know what other problems.
what I was surprised about is that there is really no documentation or usable
howto besides how to backup your desktop or small bussiness server. 

What I need is to backup several virtual hosts with 20 or so guests with as
little downtime as possible. Simplest way so far is to shutdown the guest,
make a snapshot and start it again and then backup data from that snapshot. 

I would like to find out if there is something more usable than that. If linux
gets used in enterprise environments it has to be able to backup itself
without turning off the guest but I see several problems with that and I can't
find any answers to them.

kvm virtualization, consistent guest backup

[Martin Kraus]

Hello. I have kvm guests running from lvm partitions on the host. Is there a
way to make consistent backups of the guest without shutting them down? 
The major problem I see is that there's no way to freeze a filesystem inside a
guest to make an lvm snapshot from the host. 

Does anyone have any (positive) experience with this setup?

thanks

Re: LVM snapshots are not backups (was: Re: Virtualization - what do You recommend?)

[Andrew Malcolmson]

I believe the point of the LVM Snapshot is to make an unchanging
version of your LV that can be backed up without risk of changes
occurring to the volume during the backup process.  You still have to
do the actual backup as usual.

Agreed.

Yes, it is a convenient way to "quiesce" the file system so that you get a 
consistent view of it throughout the whole of the backup process.

You backups should be protection against at least: (a) user error, (b) normal 
hardware failure, and (c) disaster.

user error: "I deleted something important, can you get it back"
normal hardware failure: "Disk #7 needed to be replaced soon, er, now.  SMART 
just failed it."
disaster: "The building the server was in burned down / flooded"

Snapshots really only cover (a).  Normal RAID really only covers (b).  
Layering the two still doesn't address (c).
