Comment 14 for bug 1746455

Hi David,

I am on-site giving a workshop to a customer this week, but I will put this
into my schedule for next week or the week after when I have spare cycles.

It should be quite easy to replicate in our lab, I just need to setup the
DHCP server and install a test cluster with vSphere.

I'll message you on IRC when I start to work on this again.

Cheers,

- Calvin
