Not sure this is a real issue for those that wish to use CentOS 8. But when RedHat brought CentOS in and then IBM bought RedHat I guess one had to see something like this coming.

I had several failed attempts until I supplemented the process with these directions:
https://sysadm.russerver.org/wiki/Install_Xen_Orchestra_on_FreeBSD

BTW it also works on FreeBSD 13.

I cannot perform a file restore from a Delta Backup of a FreeBSD VM.

• The guest tools are installed and in the rc.conf.
• UFS file system on the VMs drive.

Is this a limitation of Xen Orchestra?
