Hi Michal,

Can you advise why the following warning is logged for this command:
domain_qemu_agent_command($res,
'{"execute":"guest-network-get-interfaces"}', 10, 0)
;

warning : qemuDomainObjTaintMsg:6464 : Domain id=1 name='HA'
uuid=ffbc955e-9a51-f1d1-2501-b4cbdac5dd4c is tainted: custom-ga-command

Regards
