OK, all you xen bashers from last week -- have at it!

Xen has its place -- virtualizing many instances of a supported OS

Linux.  It works really well in that case.

Where Xen falls down is in virtualizing other OSes.  Windows under
Xen works, but the performance is crap unless closed-source
paravirtual drivers for network and disk are installed.  FreeBSD is
apparently not very well tested under Xen, or at least is having
trouble keeping up with Xen's rapid development cycle.

Spoken like a true Cascade of Attention Deficit Teenagers(tm) apologist.

I call bullsh*t.

The issue is that lack of regression testing is considered acceptable.

It is perfectly possible to add features, change architecture, adjust API's, etc. without breaking the old stuff. But you have to have a test for it.

And Xen doesn't.  That's it in a nutshell.

It's why I'll probably settle on OpenSolaris in spite of its issues. At least Sun will eventually move xVM into their testing infrastructure.

At which point we'll actually have a stable, open-source virtualization product.
