Since this is old grenade it'd be Juno code, looks like it just started:

new eventlet today: http://paste.openstack.org/show/157558/

we can backport https://review.openstack.org/#/c/145335/1/nova/virt/libvirt/host.py,cm

[Dr. Jens Harbott (j-harbott)]

There are reviews pending already for backporting this patch:

https://review.openstack.org/#/c/145955/
https://review.openstack.org/#/c/146096/

The new error messages look a bit different though, so I'm not yet certain that this is indeed the same error.

Looks like eventlet was capped on the stable branches:

[Matt Riedemann (mriedem)]

Marking this as fixed since it looks like the caps on the stable branches fixed it:

is it fixed in the nova master branch?

[Adam Gandelman (gandelman-a)]

This is fixed in master. The failure is because its not yet fixed in the juno branch, from which the grenade test is upgrading. This should fix it once it lands: https://review.openstack.org/#/c/147334/
