qemu-img snapshots configuration
Hello.
What it the difference in external snapshot configuration with and
without <domainsnapshot> ?
What is the difference between vda, vdb and vdc in the following example?

Snapshot without volumes temporarily
Hello,
I want to do a snapshot which the VM has volumes.
But I want to skip the volume check when I do the snapshot. (Which means I
want to do a snapshot without detaching the volume)
So I try to write a snapshot XML refer by
http://libvirt.org/formatsnapshot.html as following:
vda is my VM basic disk (qcow2)
vdb is a volume (raw)
================ t1.xml ===============

Excluding RAW disk from snapshot
I have an oVirt engine node that currently runs the system on a qcow2
based virtual disk, and an NFS export volume on RAW. I'd like to take
a snapshot before a somewhat risky upgrade of oVirt and can't with the
raw image attached.
Looking at the documentation for the snapshot XML, I created this XML
file for the snapshot

Any reason you aren't upgrading to newer versions? Although these seem
sufficient for what you are trying.

Live snapshots of a single block device
Hello,
I am working on a script to automatically create live snapshots of running VMs using qemu-kvm 1.4.0 and libvirt 1.0.2. If a VM has multiple disks, I'd like to back them up individually with separate calls to snapshot-create-as, so I can more easily manage the disk images. The code I have now is essentially as follows:
virsh snapshot-create-as --domain "vmname" --name

Re: Detach disk from VM - virsh (working) vs. PHP (not working)
Thank you for your help!
1, i used vda as install disk and vdb as target disk, because i boot from the first. After setup boot order flag i was able change install disk to vdb and target disk to vda. With this configuration when i boot from vdb i can install OS with grub and after it redefine XML without vdb without problem. Thanks a lot.
2, maybe i have something wrong, but still not working:

Changing a given image from virtio-blk to virtio-scsi
Any idea what 'virt-customize' script I should use to convert from
virtio-blk (vda, vdb...) to virtio-scsi (sda, sdb...) ?
I've tried naively to convince libvirt to use virtio-scsi and still present
it to the guest as 'vd*' - that didn't work (
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>

Recover snapshots from qcow images
Hi guys,
I had to move to the new laptop week ago and I screw migration of my virtual
machines. I recovered my virtual machines on the new laptop (virsh define)
using the backed up xml files, but I am missing any file with metadata about
snapshots. The original storage is cleaned so I cannot take these files
anymore.
Using qemu-info I can see my snapshots inside the qcow images, but libvirt

Snapshots
Hello,
I would like to ask what I am doing wrong and what is the best approach to
resolve this situation:
First of all I start virtual machine by virDomainCreateXML. In my
application I use libvncclient library that sends mouse events to this
running domain. I had some troubles with coordinates of mouse cursor but all
problem was solved when I added <input type='tablet'
