Rob, z/VM is an extremely stable product. We use it to run around 40 or so Linux guests. A Linux system in an LPAR can and does have problems that a Linux guest running under z/VM will not have. z/VM handles it in such a way that the Linux guest does not see it.
Any time I have to apply any maintenance or patches to these three LPARs, I boot them under z/VM to apply the fixes, shut them down and IPL them from the HMC. Earlier this year, I took one of our LPAR systems down, and booted it in z/VM. I applied some fixes to it. Then booted it in an LPAR. The system got down to a certain point in the boot sequence and went into a loop. (The problem had to do with Linux not being able to sense a PAV properly.) I ended up having to do a cio_ignore to effectively disable PAV for that device. However, when we are involved in an Early Support Program and it is early enough in the early support program where IBM has not even announced the level of code we are running, then z/VM is not so stable.
