Another question is related to SELINUX config change for below 2 parameters to recover from error "*internal error Failed to open socket to sanlock daemon: Permission denied*" I saw some where this is fixed but not sure why it appears VDSM should take care of this auto setsebool -P virt_use_sanlock=on setsebool -P virt_use_nfs=on
