Xianxian, What's the guest dmesg or console log? Is it similar with https://bugzilla.redhat.com/show_bug.cgi?id=1350719#c53? (In reply to Qunfang Zhang from comment #2) > Xianxian, > > What's the guest dmesg or console log? Is it similar with > https://bugzilla.redhat.com/show_bug.cgi?id=1350719#c53? Ignore it, attachment is there already. Looks like another dupe of bug 1350719. *** This bug has been marked as a duplicate of bug 1350719 *** |
