Is an update required for libvirt 0.8.8 in 11.4? Although honestly, without further digging, I'm not sure what the fix is. The patch in #5 is a hack to another package. The patch in Ubuntu bug 578527 is already in libvirt 0.8.8. In RH bug 593577, Jamie claims it's an apparmor issue.
Patrick, does libvirt 0.9.1 solve the issue for you?
Jim, it seems like upgrading to libvirt 0.9.1 solves the problem. And putting my system back to 0.8.8 brings it back. I really didn't expect it to be libvirt, I suspected qemu. My testing is with apparmor disabled(from yast's toplevel checkbox for apparmor, I hope this turns it off!). Thanks for the suggestion. Sorry I could not narrow it down further. If you'd like to see the problem in action, let me know. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
