Re: [atomic-devel] Atomic Host on Xen PV VM

[mabi <mabi protonmail ch>]

Hello,

I am still trying and very interested into managing to run CentOS Atomic Host with Xen using paravirtualization.

What I did for now is to install in a Xen HVM VM using the Atomic Host ISO file and now I am trying to convert this HVM into a PV using pygrub to boot the VM. Unfortunately it does not wanto to boot. Pygrub complains that it can't find the partition with the Linux kernel:

Traceback (most recent call last):
  File "/usr/lib/xen-4.8/bin/pygrub", line 882, in <module>
    raise RuntimeError, "Unable to find partition containing kernel"
RuntimeError: Unable to find partition containing kernel

Anyone has any idea? or is it simply not possible to run Atomic Host on a Xen PV VM?

Regards,
M.
