Does Squeeze's linux-image-2.6.32-5-amd64 already includes Xen PV
support? I believed it was included since v3.0.
I'm quite sure it's the same stock kernel image, I has the same MD5
hash as a regular Debian 6.0 64-bit installation I have around.

Upstream Linux has had Xen domU support since 2.6.24.
So yes, Linux 2.6.32 default kernel has pvops Xen PV support.
I feel like need to go back to school... Have always been using
*-xen kernels, even in DomU's.

-xen kernels is still better.

All vanilla kernels<  3.0 can't raise memory over initial value
(even static max>  dynamic max), and time is screwed after
migration, and MemTotal is not equal to mem_kb for domain... It can
works, but we still using suse's -xen forward-ported kernels,
because they more polished, than upstream.

kernel-xen in Squeeze is *not* Suse's forward-ported kernel.
It's pvops, with some additional patches for pvops dom0 support.
Squeeze kernel is really bad, so we using suse 3.1-xen for debian and ubuntu.
