[Bug 1847806] Re: eoan: ppc64el install on pseries-eoan VM fails to install

[Mathieu Trudel-Lapierre]

I'm not sure what to think about this failure; what's clear is it's not
'ubiquity', because we're dealing with debian-installer, but I'm not
sure what component. In fact, it looks more subtle than this, some sort
of more obscure failure:

There are various instances of 'Illegal instructions' in syslog and
errors we really shouldn't be seeing.

What type of CPU configured to virtualize ppc64el? The exact -cpu option
in use might be the culprit here.
