Ok, now that I knew what to look for I guess I found it. #1 Workaround (other than installing cockpit) for now can be a commandline call like: $ virsh pool-create-as --name home --type dir --target /home
#2 testing without virt-manager $ virsh pool-define-as --name home --type dir --target /home --print-xml > home.xml $ virsh pool-define home.xml $ virsh pool-build home error: Failed to build pool home error: unable to control COW flag on '/home', not btrfs: Function not implemented $ virsh pool-start home This is upstream issue: https://bugzilla.redhat.com/show_bug.cgi?id=1866157 Which has a fix at: https://gitlab.com/libvirt/libvirt/-/commit/2edd63a0dbd445112db23596ee0128521e8f1ff5 This is fixed in libvirt >=6.7 I'll need Ubuntu 21.04 be "fully open" for development first, then fix it in 21.04 (libvirt changed to meson, that can be a bit of work). Once fixed in 21.04 we can consider an SRU of the change for 20.10 (Groovy).
