Colleagues, could you please advise what a problem could be in XML file in
case of:
virsh backup-begin lubuntu2 ./backup.xml
where backup.xml -
<domainbackup>
<disk name='/var/lib/libvirt/images/lubuntu2.qcow2'
type='file'>
<target file='$PWD/scratch1.img'/>
<driver type='raw'/>
</disk>
<disk name='/var/lib/libvirt/images/lubuntu2-1.qcow2'
type='file'>
<target file='$PWD/scratch2.img'/>
<driver type='raw'/>
</disk>
</domainbackup>
and domain config is-
