Re: [ovirt-users] ovirt snapshot issue

Hi All, Any idea on the below? I am using oVirt Guest Tools 4.2-1.el7.centos for the VM. The Window 2016 server VM (which it the one with the relatively big disks: 500 GB) it is consistently rendered unresponsive when trying to get a snapshot. I amy provide any other additional logs if needed.
