[THIN] Re: quick question on virtualization platforms

I wouldn't call oversubscribing the host's memory a plus. It's one of those
things you have to be really careful about.

IMHO:

At this point in time (as things are changing) VMware has two plusses
over the others in the current and immediate future:
1) host memory over-commitment
2) VM portability across hardware (as in all devices are 100% emulated
thus no hardware redetection in the guest OS at all).

I first cut my hypervisor teeth on ESX just prior to Virtual Center
and even the advantage that Virtual Center gave VMware in the past
couple years is quickly disappearing.

The decision is quickly coming down to cost, features, and familiarity.

Do you really need VMotion? or is QuickMigration / Live Migration good
enough?
Do you really need DRS? (many have it, few really _use_ it)
Are you recommending VMWare just becuase you are familiar with it (and
vice-versa)?

Either way, the playing field of features is quickly flattening.
