I haven't tried that myself - so I can't confirm that. BTW is this
TRUE?, does OpenIndiana contain
xVM/XEN compatible PV Kernel?)
Would except Oracle to keep Xen DomU ( not Dom0) support in solaris 11,
unless all xVM core team left.

I recenty asked same question at Openindiana Wiki / Openindiana Releases / ... / OpenIndiana oi_147 - What's New
and also at Illumos Project forum:
Looks like Oracle will drop xVM from theirs next Solaris release (probably because Oracle bet on own hypervisor - Oracle VM,
if I recall it is linux based XEN - too bad).
And if things goes that way it will be not politically correct (from binary compatibility point of view) to include xVM in OpenIndiana.
It's a shame because as I and also many others discovered that "Crosbow + xVM (XEN) + ZFS (better external ZFS based storage for VMs) is a killer feature combo".
>From what I gather from IRC/mailing lists/blogs it's not an easy taks to maintain xVM dom0 code in kernel (and also throughly test that), not mentioning updating that to XEN 4.0 compatible.
There were also some proposals for creating xVM revital project at Illumos site (specially targeted towards linux XEN devs - after KVM is gaining more attraction on Linux), but it's looks like they didn't get any interest.
Missing dom0 (xVM/XEN) support in OpenIndiana is one thing, but worse is that it can't be run as PV guest in XEN(xVM) = PV domU (as others said - I haven't tried that myself - so I can't confirm that. BTW is this TRUE?, does OpenIndiana contain xVM/XEN compatible PV Kernel?)

People need Xen in order to run various Linux distros and Windowzes (best if they can be PV / pv enabled with i/o + net drivers) on same hardware next to Solaris based hosts. For zones - I'm going to try and use them. I'm rather completely convinced that I'll deploy production servers inside zones (java app servers + db servers and so on), but I'm also planning to put that in separate PV domU system on xVM hypervisor - so I coud easilly move such complete zones enabled (running) VM machine to another physical server (using xVM "live migration" for eg.).
