Hi Andrija, We use KVM heavy in production. We don’t encounter such a problem.
What we saw was the following. 1. If you use the maintenance mode and very often it’s not possible to mount a iso on the destination host. We don’t why this problem but normally that should not a problem. The main problem is that in maintenance mode virtual machines will be powered off if they can’t migrate. This is very ugly. 2. Normal migration should not power off virtual machines. I don’t understand why iso can not be mounted on dest host at the moment. This is not an nfs problem but we think a bug in CS. We don’t know where it comes. We don’t encounter other failures at the moment. Which work PR you are talking about?
