Mitaka ha ping test failing to ping vm

[Ben Nemec]

This appears to be a different bug from the one breaking the nonha job. This one successfully uploads the image and boots the vm but fails to ping it. Looking through the logs I don't see anything obviously wrong, but I do notice that when we try to show the console log of the booted vm we get no output. I don't see any errors that would suggest it didn't boot correctly, so I'm not sure what's going on there.

Reproduced this behavior locally and it looks like the vm is hanging at an ipxe boot screen.

It appears to have something to do with the newer seabios-bin package that came in since this job was working. The current failing version is seabios-bin-1.9.1-5.el7.noarch. If I download the older seabios-1.7.5-11.el7.x86_64.rpm from http://buildlogs.centos.org/centos/7/virt/x86_64/kvm-common/ then booting the vm works as expected and it pings correctly. This is also the version of seabios-bin that was in the last passing mitaka job I can find.

I also tried going back to 1.9.1 to verify it wasn't the vm reboot alone that fixed the problem. It hung again on the newer package.

seabios-bin-1.9.1-5.el7 is CentOS 7.3 base, so this needs to be raised as RHEL bz

I believe using the rdo-qemu-ev repo in the mitaka jobs will work around this problem. I'm not sure whether we should be using that repo with that release, but it's working for me locally. I pushed https://review.openstack.org/#/c/418510/ to test it.

I will also followup on the fact that using the qemu in base centos doesn't seem to be working.

Opened https://bugs.centos.org/view.php?id=12632 for this issue.

A workaround for this is in the gate, so I'm going to drop the alert tag so it stops spamming the channel.

[Ben Nemec (bnemec)]

This appears to have been fixed. https://review.openstack.org/#/c/425753/ will remove the workaround.
