[ovirt-users] 4.3.5 VM Guest filesystem corruption while deploying from template and root owned files problem.

Just upgraded from 4.2.7 to 4.3.5 with preserving 4.2 compatibility in cluster level. Everything is smooth and keep up and running over two weeks. However when we just want to deploy from existing Centos Linux VM Template, the VM shown "not a correct XFS inode." "file /grub2/i386-pc/normal.mod not found" error. Also tried another RHEL and OEL template, they all have same problem. So I tried to install a new Linux and converting to template to see whether it is existing disk problem, but it appear the same xfs error after template deployment. Have been tried on qcow2 and raw format. no different. The interesting finding is Windows Server Template doesn't suffer this problem. So is it from image tools bug? Secondly, I noticed there are intermittent issue where ovirt node create image objects owned by root user, and that cause VM fail to start. It happens likely when creating VM image snapshot and after restore snapshot. Anyone can point me out where should I looks into. Thank you!
