[libvirt-users] qemu-img snapshots configuration
Hello.
What it the difference in external snapshot configuration with and
without <domainsnapshot> ?
What is the difference between vda, vdb and vdc in the following example?
(From https://libvirt.org/formatsnapshot.html)
<domainsnapshot>
...
<memory snapshot='no'/>
<disks>
<disk name='vda' snapshot='external'>
<driver type='qcow2'/>
<source file='/path/vda-delta.qcow2'/>
</disk>
<disk name='vdb' snapshot='no'/>
<disk name='vdc' snapshot='no'/>
</disks>
<domain>
...
<devices>
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/path/vda-img.qcow2'/>
<target dev='vda' bus='virtio'/>
</disk>
<disk type='file' device='disk' snapshot='external'>
<driver name='qemu' type='raw'/>
<source file='/path/vdb-img.qcow2'/>
<target dev='vdb' bus='virtio'/>
</disk>
<disk type='file' device='disk' snapshot='external'>
<driver name='qemu' type='raw'/>
<source file='/path/vdc-img.qcow2'/>
<backingStore type='file'>
<format type='qcow2'/>
<source file='/path/vdc-delta.qcow2'/>
</backingStore>
<target dev='vdc' bus='virtio'/>
</disk>
...
</devices>
</domain>
