I have 2 machines.
One is 64 bit VT and another is non VT 64 bit.
Both are Ubuntu desktops.
I am trying to compile Xen-4.0.1 and each time pull git clone from JF's tree.
In any of the systems things did not worked.I am able to boot without
hypervisor but not with hypervisor.
I.e. pv-ops Dom0 kernel 2.6.32.27 I am able to boot.But if I do with
Xen then things do not work.
I tried adding noreboot option in grub2 as suggested by some one but
it did not helped.
My problem is it is rebooting so frequently that I am not able to even
note down the error message.
I am not clear if I can use with some older version i.e. Xen-3.0 but
then what kernel do I need for that?
I am not sure but what I observe is things keep randomly changing when
it comes to Xen if some thing worked for some one it is not
necessary that your experienced sys admin would be able to use it
though he might be an expert of Linux but he may fail 100% to boot
with Xen.
Looked through wiki/google/books etc etc.

I feel some other solutions  are better when it comes to Xen.I tried
KVM and happily without any problem (on the VT machine in question)
was able to use things absolutely flawless work.But when it comes to
Xen you need to go through wiki docs ,compile kernel and God only help
you.
Rather than getting your business application up and running you will
struggle through it.Given the fact I do not have such constraints and
I am doing it for my understanding.But I really find it bizarre when
it comes to Xen be it wiki or the software itself.I do not have a good
time with Xen.
