Hi, I just spent some time figuring this out, as I had a similar problem. It looks like you have a pool on /var/mnt/LinuxData/VM. You will want to run the command setfacl -m u:qemu:rx /var/mnt/LinuxData/ The virtualization maintainer HikariKnight used some bar analogy for it, but it just needs extended permissions on the root of the mount. In my case I have my ISO on a mounted external drive, and was giving me this error. I'm sure it's the same issue for yours
