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 .

[root@localhost oscgpkg-7eee963550ba9e5b]# virsh snapshot-create --domain oscg2 --xmlfile oscgsnapshot.xml

error: unsupported configuration: disk 'vda' must use snapshot mode 'internal'

[root@localhost oscgpkg-7eee963550ba9e5b]#

[root@localhost oscgpkg-7eee963550ba9e5b]# cat oscgsnapshot.xml
