Error Starting domain: Failed to page size of file
I am trying to connect a KVM-QEMU VM to OVS-DPDK vhostuser port. But, I am encountering a few errors. Since I am very new to libvrt and Linux I am not able to sort them out. Any guidance in this regard would be a great help.

Re: error: internal error: missing backend for pool type 11 (zfs)
@Michal: Thanks for your reply! Indeed I have found a package in the AUR (libvirt-zfs) and only had to change to the current version and add zfs-utils as dependency in the PKGBUILD. Now I don't get the previous error anymore but I still cannot setup a VM because I constantly get errors due to wrong permissions. I have tried to change the permissions in: - /etc/libvirt/qemu.conf -

scsi passthrough differs between guests
Greetings, I have two machines running the same distro, both running qemu 5.1.0, one runs libvirt 6.7.0, the other 6.8.0. I've decided to test the viability of passing through my sata cdrom into a vm, so I went to the libvirt docs, read a bit and added the following to a debian10 uefi vm running on libvirt 6.8.0: <controller type='scsi' index='0'
