Fwd: (no subject)
Thank you so much for your informative response. The man page of virsh did
not include "snapshot=no" sub-option under the --diskspec option, but it is
very intuitive. Thanks developers for their excellent work!

virsh create snapshot not honoring diskspec?
Hi,
I'm trying to create a snapshot on a specific disk by using diskspec
option. However, libvirt/virsh seems to ignore it and takes a snapshot of
all disks. Am I using this option incorrectly?
In below examples, I'm trying to snapshot only vdb. However even vda is
getting snapshotted regardless of diskspec. Is this a known issue?
I'm on CentOS 7.1, libvirtd (libvirt) 1.2.8, virsh

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

I’ll try and keep the lines short. I don’t see any obvious setting to change the wrap.

Re: Clone VM with saved state
Hi Kashyap,
Thanks for your answer!
Unfortunately my use case requires cloning the exact memory state, so I
won't be able to use virt-sysprep.
But the snapshot command looks like something I could use.
Could you suggest how to proceed and create/start a new vm from that
snapshot?
Thanks,
Michael

Clone VM with saved state
Hi,
My use case involves creating duplicates of saved virtual machines.
Tried with virt-manager and with virsh but so far it seems like this case
is not supported by these tools.
Does anyone know how I could achieve the above?
Thanks,
Michael

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:

CentOS 5 grub boot problem
I never thought I'd say this, but I think it's easier to do this with
GRUB 2. Anyway I did an installation to raid1's in CentOS 6's
installer, which still uses GRUB legacy. I tested removing each of the
two devices and it still boots. These are the commands in its log:
: Running... ['/sbin/grub-install', '--just-copy']

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)
