Xen and CentOS7.2 (PV)

I always set up my CentOS VMs as PV mode (yes, I know PVHVM/etc) under FC23 host but this time it’s not working. It is BROKEN.

[ OK ] Started Show Plymouth Boot Screen.

Reverting to CentOS 7.1 PXEBOOT images seemed to work fine.

Looks like there might be 2 articles that cover this:
* https://lkml.org/lkml/2015/12/7/862
* https://access.redhat.com/solutions/2044313
In short, CentOS/RH 7.2 is broken.

Update: 13/01/15
* FC23 on latest 4.5 Xen and the issue has progressed to the ‘setup’ menu, but Probing hard drive hangs when selecting drive.

  1. To further this – I have tried HVM install – it appears to work fine but converting this back to PV caused the VM to die horribly (requiring rebuild)

  2. Looks like this only happens on the Xen that comes on Fedora. Working off XenServer it appears to work fine to boot.
