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.

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?

The first hit on Google for external snapshots involves a RHEL7 document that talks

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 Jatin

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
