We haven't been using the OVA but converted a RHEL6.7 MA over to be the File Recovery Enabler but I've noticed that browsing any 3.x kernel VMs results in failed browse (couldn't mount volumes, etc.). It doesn't appear to be an XFS thing as the packages are on the FRE machine. Browses of RHEL5.x machines, no problem. Some RHEL6 VMs I can browse, others not. It isn't an ext4 problem or XFS specific. Am I being dense here - does the FRE machine always have to be newer than any backed up VM volumes it needs to mount?
