Xen users - Jan 2012 - how to determine if the convertion from hvm to pv succeeds?

Hi,all
  I installed ubuntu 11.10,and tried to convert it to PV mode.Now the
PV-bootloader is pygrub and
I have also set the PV-bootloader-args respectively.How do I ensure myself
that this convertion is successful
or not?  I can  log in to the system,is this any evidence at all?thanks

Sincerely yours,
Jeff

Yes.

Otherwise if you need to make a standardized test, use the following conditions:
- xm create -n still works
- pygrub (externally called) can extract vm kernel
- when the vm is created, the xenstore should have some keys that prove it is PV
- inside the vm, you''ll need you disk & network & console
drivers too.

Also it''s worthy to test if the varios hotput features work (adding
vcpu, mem-set).
Each distro comes with it''s own set of bugs in the pv kernel.
