Hi Christian, Bit of an update, there seems to be two different but linked problems.... I have downloaded qemu-system-86 ubuntu source and patched support back in for zesty, all snapshots now work. However I still cannot edit snapshots using virsh , get same error.
I then downloaded libvirt-clients ubuntu source and edited libvirt-4.6.0/src/conf/domain_conf.c Removing machine check , i.e. commenting out the 'goto error' failure in this if; if (STRNEQ_NULLABLE(src->os.machine, dst->os.machine)) { I can now edit the snapshots ok (e.g. change machine to cosmic) so they work with original or patched qemu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1802944 Title: error: unsupported configuration: Target domain machine type To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1802944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
