Re: Debian 10, xen 4.11 reliability

[JP P <jpp@xxxxxxxxxxxxxxxxxx>]

Hello,

I have exactly the same problem with XEN 4.11 and Buster, Xen does not start 
(it even does not recognize the boot fidk !) and
never detects the RAID 1 disks.
I cannot boot with Xen, the same Kernel boots perfectly OK without XEN and all 
RAID disks are OK.
I don't find any clue on Internet and can no more use Xen (I used it since 2009 
with no problems ...).

Regards

JP P

Kernel messages and all the kernel versions you've tried since Debian 7 please?

We're trying to track down some other issues with debian guests; maybe they are 
the same root cause.
