Re: Can't take live snapshot, not supported with this QEMU binary
Under libvirt 1.1.1 snapshot support is incomplete.
Source: http://wiki.libvirt.org/page/I_created_an_external_snapshot,_but_libvirt_won't_let_me_delete_or_revert_to_it
In regard to snapshotting (features and stability), I have selected these versions of libvirt and qemu:
Libvirt >= 1.2.9 (currently 1.2.12)
Qemu = 2.1.0
On Qemu 2.3 and 2.4, I have experienced a regression bug regarding

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: 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,

Re: Virsh snapshots
Thanks for your answer,
I am trying to make a snapshot of whole virtual machine (disk, CPU
state, memory). But I need to make this snapshot in matter of seconds.
I have already try to create snapshot of disk, which is not problem. I
use qcow2 format, and create new disk image using original disk image as
backing file. But still I am not able to assign state of vm with new disk.

Help with external snapshots as backups
Hi,
I have a win10 guest on a fedora32 system and have some questions as I
explore using external snapshots as a form of backup in case of a
Windows failure (as in, it won't boot or is completely irrecoverable) as
well as revision control (to be able to rollback changes after a failed
app install, etc).
The first hit on Google for external snapshots involves a RHEL7 document

SIGTERM signal to qemu-kvm process
Hi
I am using QEMU 0.12.1 as the hypervisor in my RHEL installation of 6.5.
I wanted to know if there are any side-effects with respect to VM image
corruption when i use SIGTERM signal to kill a qemu-kvm process which
effectively stops my VM running on the host.
Appreciate if you can provide me some valuable information in this regard.
Thanks

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
