Hi, dear friend. My guest has two disks, vda and vdb. both are qcow2 local file. When guest running state. I want to take the vda snapshot of guest(just vda, no include vdb). but I met libvirt do snapshot for all disks of guest. About methods for follow: 1、 ``` bash virsh snapshot-create-as 8x0lbzvS --name sys_disk3 --disk-only --diskspec "vda,snapshot=external" ``` ``` result

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

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 <domainsnapshot> <name>20120802</name>

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 =============== <domainsnapshot>

Hi all, I was trying to take live snapshot of VMs, but I got the following error: [root@localhost ~]# virsh snapshot-create-as 1 test desc --live --memspec file=mem.bak,snapshot=external --diskspec vda,snapshot=external,file=/root/root.bak.qcow2 error: Operation not supported: live disk snapshot not supported with this QEMU binary I upgraded my qemu-kvm 0.12.1 to qemu 1.2, the error still

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

Dear all, Please let me start by indicating that I am not from a technical background, so please be gentle and patient with me. I am trying to get a snapshot from my virtual machines (vm) and the following command works for all of them bar one: # virsh snapshot-create-as --quiesce --no-metadata --domain myvm myvm-state --diskspec vda,file=overlay.qcow2 --disk-only --atomic The only exception is

I scripted the creation of snapshots and it works fine. Now I'd like to run the script as non-root. virsh snapshot-create-as --domain hq-live-v01 \      --name snappy \      --diskspec vda,file=/var/lib/libvirt/images/hq-live-v01.snappy,snapshot=external \      --diskspec vdb,file=/var/lib/libvirt/images/hq-live-storage.snappy,snapshot=external \      --disk-only --quiesce --atomic This

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

Thanks for you reply! Firstly, I'm very sorry I forgot introduce the scenarios in my experiments. Supposing a case, I have a virtual machine with two disks. One is mounted as a root partition and the other is data partition and the second disk is an iscsi lun, that is to say, not a local disk or image. Now the result wanted is that creating a snapshot for the root disk but not for the data

Hi Libvirt, Does libvirt-python currently support the creation of external snapshots? I ran domain.snapshotCreateXML(xml) where xml is <domainsnapshot> <name>snap1</name> <description>Snapshot of OS install and updates</description> <disks> <disk name='vda'> <source

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?

Hello. What it the difference in external snapshot configuration with and without <domainsnapshot> ? What is the difference between vda and vdb in the following example?
