Okay, I just assumed the possibility to change the driver was a suggestion to use qemu:///session (in the bug description it is mentioned as well). I just missed the touch command. It works like a charm. > You can check the commit > > http://dev.opennebula.org/projects/opennebula/repository/revisions/f8252cfe8bc49bc0ecec376476b711e5d2f1c5dd Unfortunately the changeset cannot be easily integrated into OpenNebula 1.2 since one_vmm_kvm.rb seems to be completely rewritten in OpenNebula 1.4. However, I made a small, quick and very dirty workaround for the current OpenNebula implementation of Karmic. Below you can see the patch that needs to be applied to /usr/lib/one/mads/one_vmm_kvm.rb. Yet there is still another problem. AppArmor prevents libvirt to write checkpoints outside of oneadmin's home. Is there an open bug ticket for that or should I file a new one? There was a similar bug report in an earlier Ubuntu release but the fix only gave libvirt the ability to write inside the user's home and not in /var/lib/one/... $ diff -u /usr/lib/one/mads/one_vmm_kvm.ubuntu-orig.rb /usr/lib/one/mads/one_vmm_kvm.rb --- /usr/lib/one/mads/one_vmm_kvm.ubuntu-orig.rb 2010-03-26 19:30:51.434615520 +0100 +++ /usr/lib/one/mads/one_vmm_kvm.rb 2010-03-26 19:58:07.475803935 +0100 @@ -112,6 +112,7 @@ end def action_save(args) + touch_checkpoint_file(args[2], args[4]) std_action("SAVE", "save #{args[3]} #{args[4]}", args) end @@ -179,6 +180,18 @@ res[0].close res end + + def touch_checkpoint_file(host, file) + res=Open3.popen3( + "ssh -n #{host} touch #{file} ;"+ + " echo ExitCode: $? 1>&2") + res[0].close + + stdout=res[1].read + stderr=res[2].read + + write_response("TOUCH", stdout, stderr, file) + end def write_response(action, stdout, stderr, args) exit_code=get_exit_code(stderr) -- Cold migration fails https://bugs.launchpad.net/bugs/322779 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
