Public bug reported:
Binary package hint: kvm
$ lsb_release -rd
Description: Ubuntu 8.04
Release: 8.04
$ uname -a
Linux mblakele-lt 2.6.24-16-generic #1 SMP Thu Apr 10 12:47:45 UTC 2008 x86_64
GNU/Linux
$ apt-show-versions kubuntu-desktop
kubuntu-desktop/hardy uptodate 1.75
$ apt-show-versions kvm
kvm/hardy uptodate 1:62+dfsg-0ubuntu6
I started kvm using:
$ kvm -hda ReactOS.qcow2 -net nic,model=ne2k_pci -net user
While mousing around, the kvm window froze on my KDE desktop. The mouse
was captured, and ctrl-alt did not release it. I was able to switch to
VT01 with ctrl-alt-f1, and found that there was a single kvm process,
listed as defunct. As might be expected, it did not respond to kill or
kill -9, even via sudo.
$ ps waux | grep kvm
mblakele 2396 1.5 0.0 0 0 ? Zl 11:50 0:30 [kvm] <defunct>
The dmesg output showed a stack trace, starting with "Unable to handle
kernel paging request" and mentioning
kvm:kvm_mmu_slot_remove_write_access+0x55/0x70 and
:kvm:kvm_vm_ioctl_get_dirty_log+0x82/0xc0 (attached).
I used ctrl-alt-backspace to kill X, and was able to log in to file this
bug. I haven't tried another kvm session yet, as I suspect it'll freeze
the machine. I'll try that after filing this report, and add the results
as a comment.
