2.6.35-30-server #54-Ubuntu SMP Tue Jun 7 20:13:05 UTC 2011 x86_64 GNU/Linux ..... Working fine !! Tks ! At least in my case, lucid still have some glitches while xenmotion, but its much better with the latest kernel release. Maverick seems to be working fine using the 35-30 proposed kernel. All 8 xenmotions to different hosts worked, no fail. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/681083 Title: Ubuntu Crashes/Freeze on XenMotion To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/681083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
