master.cfg snippet:
{{{
from buildbot.libvirtbuildslave import LibVirtSlave
from buildbot.libvirtbuildslave import Connection
connection = Connection("qemu:///system")
c['slaves'] = []
[...]
slave = LibVirtSlave("arch32", "<password>", connection,
"/data/vms/snapshots/arch32.tmp", base_image="/data/vms/arch32.img",
max_builds=1, missing_timeout=30, build_wait_timeout=30)
c['slaves'].append(slave)
}}}
A builder associated with this slave will cause the (qemu-kvm) virtual
machine to start, from a snapshot overlay disk, just fine. The buildslave
on the VM starts, connects, the build starts, and finishes, or fails..
this is not the issue here..
The problem is that after the build, it doesn't manage to stop/destroy the
VM, leaving it running. Apart from taking up memory, this also de-syncs
the states between libvirt and buildbot, so that you can't start the build
again.
below is a stacktrace from a manually interrupted build (but the last line
is the same regardless of how the build terminates:
