*** This bug is a duplicate of bug 1307473 *** https://bugs.launchpad.net/bugs/1307473 I am not sure whether this bug is really a duplicate of #1307473. I experienced the problems described in this bug report without CPU pinning being used. I might add that I had the impression that Windows guests (Windows Server 2012 R2) were more severly affected than Linux guests. However, Linux guests seemed to be more affected if also running the 3.13 kernel. In my case, I experienced the problem after upgrading a VM host from Precise (using kernel 3.5.0-52) to Trusty (using kernel 3.13.0-30). For now, I downgraded back to Precise which made the problems go away. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1333553 Title: linux-image-3.13.0-29-generic - soft lockup in kvm guests To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1333553/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
