@smb - after repeating the test a few times, I too ran out of space with
the default 8GB VM disk size, resulting in a paused VM. You'll have to
re-create the VMs a little bit differently (--disk ).
ex:
@L0:
sudo uvt-kvm destroy trusty-vm
sudo uvt-kvm create --memory 2048 --disk 40 trusty-vm relea
I've collected crash dumps, and have stored them on an internal

A few hrs later, those two L0 bare metal host CPUs are still maxed. In
scenarios where L0 is hosting many VMs, such as in a cloud, this bug can
be expected to cause significant performance, consistency and capacity
issues on the host and in the cloud as a whole.

This does not appear to be specific to OpenStack, nor tempest. I've
reproduced with Trusty on Trusty on Trusty, vanilla qemu/kvm.
Simplified reproducer, with an existing MAAS cluster:
@L0 baremetal:
- Create a Trusty bare metal host from daily images.
- sudo apt-get update -y && sudo apt-get -
Also FYI: I was not able to reproduce this issue when using Vivid as
the bare metal L0.
