libvirt users - Sep 2015 - Error during virt-install, error is not for the guest being instantiated

Hi,

I have two processes spinning up independent sets of guests, letting the guests
run for a while, and tearing them down.

The two processes are generally giving their set of guests a different
"run-period", so the guest spin-up/tear-down will happen during
different cycles/phases.

Call these processes A and B, each is currently managing 32 guests.

I am seeing an issue, where when process A is spinning guests up, and process B
is tearing them down, where on process A, a virt-install will fail, but the
error identifies a recently terminated guest which is managed by process B.  The
guest being instantiated does not get instantiated.

"ERROR    Error: --network default: Domain not found: no domain with
matching uuid 'd39587cb-a2e8-4989-8dce-12a12eb2815e'
(process-B-guest-name)"

This message is logged by my script at 3:29:23PM.

This message is in /var/log/messages;

Sep  1 15:29:21 splat04 systemd-machined: Machine qemu-process-B-guest-name
terminated.

Seems to me that there is some sort of mixup going on, process-B-guest-name is
terminated during the virt-install for process-A-guest-name.

Any thoughts on this?  Like hints on what to look for?  This is on Centos7, the
version of libvirt is 1.2.8, virt-install is 1.1.0

Thanks - Joe

I enabled all logging levels from libvirtd.  I can see at 15:21:31, the domain
from process-b getting undefined (virsh undefine (domain-name)), the
virt-install from process-a is launched at 15:21:30, so it seems like the
undefine of the process-b domain, confuses the virt-install for process-A's
domain/guest, it fails to instantiate the process-A domain/guest.

Could be some issue virt-install hits trying to fetch the XML of another VM
that it wants to ensure the new VM doesn't collide with (storage path, mac
address, etc). The --debug output would probably confirm... but try the latest
version of centos with virt-manager 1.2 at least before filing a bug
