define domain just edit the persistent xml. So we should get user and group from persistent xml instead of live xml when domain is living. Sheldon found this bug: when we set kimchi metadata when vm is running, we cannot read corresponding info,

Royce, I made some tests and even with this patch when I updated users/groups in a running VM the changes only take effect in next boot
I found the problem. To fix it we also need to do:
+ xml = dom.XMLDesc(libvirt.VIR_DOMAIN_XML_INACTIVE)
in lookup()
I will adjust that before applying
Sheldon, as you will need to update this patch according to my comments, could you also update lookup()?
