I'm not sure I fully understand what happened here.

If it detects that /dev/kvm is missing, it should do a repair action which corrects the problem with a cold reboot (ec reset). Does this provision check not do the repair that way?

Who's working on this? CQ and Release bugs need an owner.

I'm not sure what the problem here is. I can find a bunch of provision errors by searching stainless and see a bunch of these since I made this change. However, if I then SSH into the device.../dev/kvm is present..and if I lock it and run verify() on the host it completes fine as well.

I don't understand if provision is different than repair/verify to know what to look at to investigate this more. I'll be OOO all next week as well.

I'm going to need some help figuring this out as I'm not that familiar with how the lab runs.
