[Bug 1047040] Re: kvm crashed on precise - memory corruption
@serge-hallyn Sorry for the late respond. The image file is provided by internal colleague in my company. I am not sure if it is suitable to provide it to others other than the one in our company. However, it seems behaves differently on different hardware configuration. The VM was crashed always on some 1U or 2U server. But it seems work fine in my personal desktop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1047040 Title: kvm crashed on precise - memory corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1047040/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It seems that I have a VM image which could cause this issue definitely in a small round of reboot stress.

Recently I also encounter this issue. I am running reboot stress test with ubuntu desktop. After 2xxx times, the VM shutdown then reboot to have the same memory corruption information in qemu.log. It also causes my libvirt responds wierd. After kill the VM, libvirtd works well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1047040 Title: kvm crashed on precise - memory corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1047040/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1060760] Re: Hot plug and unplug causes system hangs
There was not a problem with the current kernel but with the different chips.

apport-collect 1060760 can't be run on this machine. I will collect some log files if needed. Besides, I have tried installed the kernel v3.6.1 and the Intel C600 driver is v1.1.0. Retry the scenario with a disk unplugged then plugged again.
