Reliability and uptime, in our experience with RHEV, are all based on Linux, and the next version of Linux will have that in-memory upgrade capability, so you can literally upgrade the kernel without rebooting. 

For now, it's similar to its competitors – if you're upgrading a machine, you just vMotion everything off of it, upgrade your one node, move them back, clear the next node, and so on. But in the very near future, you won't even have to do that. You'll be able to do the in-memory upgrade.

I haven't seen any major issues with stability. Ten being the best, I would rate Red Hat and VMware both at a nine and Microsoft at an eight.

The product is stable. I have deployed it for five to ten customers. There have been no issues. I rate the stability a six or seven out of ten.

We have found this solution to be stable. However, if issues occur then we have found it quite complex to start the product working again.

It is a stable solution.

Red Hat Enterprise Virtualization is quite a stable solution.

It is a stable solution.

In comparison to VMware, this solution isn't as stable. We're testing it right now, and we're not trusting the stability of the product.

I have found that the stability is related to the upgrade cycle. I find the cycle a little bit annoying.  If the system is constantly upgrading then it is very painful in terms of the operation.

It is a very stable solution.
