Comment 52 for bug 1847105

On a system affected by the issue I was upgrading to focal-proposed:

The time on ZFS got down from >20sec to ~<2sec now and in ps I can catch it is back on metadata as intended:

$ ps axlf | grep -e qemu-img | grep -v grep
0 0 48981 11928 20 0 164860 5020 ? Sl ? 0:00 \_ /usr/bin/qemu-img create -f qcow2 -o preallocation=metadata,compat=1.1,lazy_refcounts /var/lib/libvirt/images/ubuntu20.04.qcow2 15728640K
