Xen users - Apr 2012 - pygrub questions from domU viewpoint

I have a virtual server Xen domU rented and want to be able to
change kernels.  The provider, thrustvps.com offers so little support, it is
hard
to make any progress, so I am wondering what you can find out from the domU
perspective
about booting?

So far, any change to kernels in /boot/grub/menu.lst won''t boot. 
That''s a big hassle
because once it won''t boot, they provide no way to restore from my
backup, at least, not
with a generic account.  They have stopped offering Xen PV and offer Xen HVM
instead now.

What''s a good Xen pv provider for low traffic, similar terms as
thrustvps:
512MB RAM, 1GB Burst 1TB Transfer 1 IP located in Dallas  per month $8.

Is amerinoc.com good?  Should I start out with HVM since PV seems more tricky
to get an upgrade to the kernel to work?

thanks,

John Griessen

Not much. The booting process is too much dependent of the boot loader. 
If you can''t interact with it, you can do nothing with confidence.

Is your /boot/grub/menu.lst taken into account at all or it is not (Dom0 
provided kernel)?
What are the changes you have tested?

Maybe they can give you a access to VM console, to monitor/alter the 
boot process? Xen have a standard way to export the console, as VPS 
customer you should expect to be able to get access to it. Once done, 
you may do whatever you wish to Grub with a good confidence.

(don''t CC me, i read the list)
