<group> could be an additional element in the nodedev-create XML:
<device>
<name>my-vgpu</name>
<parent>pci_0000_86_00_0</parent>
<capability type='mdev'>
<type id='11'/>
<uuid>0695d332-7831-493f-9e71-1c85c8911a08</uuid>
<group>group1</group>
</capability>
</device>
(should group also be a UUID?)
Since John brought up the topic of minimal XML, in this case it will be
like this:
<device>
<name>my-vgpu</name>
<parent>pci_0000_86_00_0</parent>
<capability type='mdev'>
<type id='11'/>
</capability>
</device>
The uuid will be autogenerated by libvirt and if there's no <group> (as
is common for VMs with only 1 vGPU) it will be a single-device group.
Thanks,
Paolo
