[Info-vax] VMware

A point of interest, Charon I believe claim VMware certification

Not sure if that includes an OpenVMS cluster or individual OpenVMS nodes migrating, I suspect the latter

For those wanting to read a light article on what VMware basically does during a migration, read the following link

We and others often see issues around stun times. In fact we have a current issue that has gone to VMware/Dell to be addressed which almost certainly will result in a patch being released. Migrations are complex beasts

I think OpenVMS might need a bit of work fitting into a virtualized world especially where migrations are happening. The complexity in handling a node member of an OpenVMS cluster member might be very interesting indeed. 

A single standalone node is one thing, migrating a cluster member might be a very different matter. You might have to come up with a formula not to migrate more than x members of an OpenVMS cluster at once etc. I don't know, I just know that when you start to deal with HA clusters things get exponentially complex very quickly

It's very good news that OpenVMS is looking to be supported in VMware, very good news indeed
