As a general rule, libguestfs is only guaranteed to work if the host OS is the same or newer than the guest OS. It might (and often does) work if the host OS is older than the guest, but that's pot luck. The libguestfs appliance use the host kernel to access the filesystems, so if the guest OS kernel was newer, its filesystem may have used features that the host OS kernel doesn't understand. IOW, my assumption is that Fedora 35 xfs is using fetures that RHEL8 xfs doesn't support.
