Argh.. even more forward porting from xensource 2.6.18 tree instead of
porting to pv_ops and getting the pathes integrated upstream to vanilla
kernel

I guess it was faster _now_, but they'll have to live with the forward
porting pain for years more now..

dom0 looks currently out of reach,
what we have is the snapshotting features of 2.6.27 for x86_32.

While this is true, the patches still allow for Debian to ship Lenny
without a feature regression in Xen support.

Hmm.. what do you mean with "out of reach" ? pv_ops dom0 is not yet
ready/working, but those SLES 11 patches have the xensource (2.6.18 forward
port) of dom0 and all the other xen kernel features for 2.6.26..

I think the situation has changed after that..

See: http://wiki.xensource.com/xenwiki/XenParavirtOps

I think x86-64 xen patches are going in for 2.6.27..
