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 Setting verified ** Tags removed: verification-needed verification-needed-focal ** Tags added: verification-done verification-done-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1847105 Title: very slow disk creation, snapshotting To manage notifications about this bug go to: https://bugs.launchpad.net/virt-manager/+bug/1847105/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
