*** This bug is a duplicate of bug 1346917 *** https://bugs.launchpad.net/bugs/1346917
I upgraded to the new kernel. At this point it does appear that the fix in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1346917 has addressed the issue; I've been running now for ~38 hrs on that kernel with no issues. Marking the bug as a dup of 1346917. If something changes (note: the problem has always manifested itself faster than this before) - I'll note that. ** This bug has been marked a duplicate of bug 1346917 Using KSM on NUMA capable machines can cause KVM guest performance and stability issues -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1332409 Title: [Supermicro X9DR3-F] Virtual machines hang in kernel 3.13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1332409/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
