[Xen-users] Re: [Freedos-user] [Xen-devel] Unable to boot FreeDOS 1.0

["Geraldo Netto" <geraldonetto@xxxxxxxxx>]

Hi Guys!
How are you all doing?

Bernd, actually, i don't know because, it is Miguel's host
Miguel, can you provide details of your hardware?
Do you know if your pc supports any virtualization instruction?
ie: on intels vt instruction or on amds svm instruction?
if you use linux you can try:

'cat /proc/cpuinfo | grep vt' on intels
or
'cat /proc/cpuinfo | grep svm' on amds

and archives is here:
http://lists.xensource.com/archives/html/xen-users/

but i was not able to find out a solution

Kind Regards and Best Wishes,

Geraldo
