[libvirt-users] virsh snapshot-create --print-xml seems to ignore most arguments

Hi,

I am wondering if the --print-xml option is working correctly. The
output for two snapshot-create commands are the same, even though the
first one includes additional options (no-metadata and atomic).

I want to use the generated XML to create a snapshot via a perl script,
and Sys::Virt only seems to support snapshots using a XML description
of the arguments.


timos at cerberus:~$ sudo virsh snapshot-create-as --domain web guest-
state1 --diskspec hda,file=overlay1.qcow2 --disk-only --atomic --no-
metadata --print-xml
<domainsnapshot>
  <name>guest-state1</name>
  <disks>
    <disk name='hda'>
      <source file='overlay1.qcow2'/>
    </disk>
  </disks>
</domainsnapshot>

state1 --diskspec hda,file=overlay1.qcow2 --disk-only  --print-xml

  <disks>
    <disk name='hda'>
      <source file='overlay1.qcow2'/>
    </disk>
  </disks>
</domainsnapshot>

My libvirt version is:

Compiled against library: libvirt 5.6.0
Using library: libvirt 5.6.0
Using API: QEMU 5.6.0
Running hypervisor: QEMU 4.1.0
