[Pkg-virtualbox-devel] Bug#689271: virtualbox: hang when starting vm w/ lxc running

[Edward J. Shornock]

Package: virtualbox
Version: 4.1.18-dfsg-1
Severity: normal

I have found that starting a guest VM in Virtualbox will hang the host
computer while I have an active LXC container. The mouse and keyboard
will not respond, requiring power to be cycled or the reset button to be
pressed. "Back in the day" I experienced similiar problems with the KVM
module loaded. Unloading kvm with "modprobe -r kvm_amd kvm" does not
prevent the lock-ups this time.

The LXC container is using libvirt but only to communicate across the
network.  Stopping libvirt before running the the VM in Virtualbox does
not stop the lock-up from happening.

The host system will not lock-up if the lxc container is stopped before
the Virtualbox guest is started.

I don't see anything related in any of the logs.
