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? (From https://libvirt.org/formatsnapshot.html) <domainsnapshot> ... <memory snapshot='no'/> <disks> <disk name='vda' snapshot='external'> <driver

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>

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 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, 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 used 'virsh snapshot-create' create an encrypted external snapshot, when I try to use 'qemu-img check' top file, found no entrance to pass backing-file's secret-id 1、Version centos-release-8.2-2.2004.0.1.el8.x86_64 libvirt.x86_64 6.0.0-17.el8 qemu-kvm.x86_64

Thank you! But snapshot-create-as will traverse all disks of the virtual machine and create snapshots for all of them. In my case, I want to create snapshot for root disk. What's more. I understand "--diskspec" is a description of the disk. Do you mean it's used to specify a single disk to snapshot. 在 2013-06-26 09:10:31，"Gao Yongwei" <itxx00@gmail.com> 写道：

Hi, everyone, I have found the API snapshotCreateXML() can create a snapshot for a virtual machine, and the xml configuration file - snapshot.xml as folllows: <domainsnapshot> <name>snapshot01</name> <description>Snapshot of OS install and updates</description> <disks> <disk name='vda' snapshot='external'> <source

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:

Hi There , I have KVM VM with 4 qcow2 disks and 2 raw disks . when I try to take full system snapshot by excluding raw disks . it is give below error . can you help me how to fix this ?. or is it possible to take full system snapshot in this case .?. When I change XMl as internal snapshots for raw disks . It throws a message snapshot are not supported on war disks .

I don’t see any obvious setting to change the wrap. Thanks for being accommodating; this was indeed easier to read (alas, many web mailers these days lack settings for automatic wrap, so I end up whacking the

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

Any idea what 'virt-customize' script I should use to convert from virtio-blk (vda, vdb...) to virtio-scsi (sda, sdb...) ? I've tried naively to convince libvirt to use virtio-scsi and still present it to the guest as 'vd*' - that didn't work ( <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/>
