Ok I applied patches
http://xenbits.xensource.com/xen-unstable.hg/rev/6eaab8297681
http://xenbits.xensource.com/xen-4.0-testing.hg/raw-rev/065efaec5e71
and again booted with changed grub entries it is Ubuntu 10.04 64 bit
running in vmware
I got many error messages and could not.
So I did update-grub.d
and booted with simply pv-ops dom0 kernel
and I can see output of xm but not xm info (obviously it is not booted)
so what more should I try?
Any guesses?
