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

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

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?

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

Hi,guys I wanna to get the disk snapshot size, but found nothing libvirt commands related,except qemu-img. I create two disk snapshots, but nothing return its' size [root@cskvm01 qcow2]# qemu-img info /mnt/e6758700-af68-3c06-ade3-53f5f9b93507/e2cf6551-0d2c-4382-a86c-8ba633954ff2 image: /mnt/e6758700-af68-3c06-ade3-53f5f9b93507/e2cf6551-0d2c-4382-a86c-8ba633954ff2 file format: qcow2 virtual

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. I have found

Everyone, I am trying to create external snapshots of a kvm guest machine and have not been able to do so. In accordance with : https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_deployment_and_administration_guide/sect-troubleshooting-workaround_for_creating_external_snapshots_with_libvirt I have used the command line : snapshot-create-as --diskspec

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 that talks

Hello, I am working on my PhD thesis and it would be really helpfull if someone could advise me, whether can Virsh create snapshots of VMs using copy-on-write. Thanks for reply. Juraj

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

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
