Hi,
I am trying to set up fully virtualized guest VMs (Fedora core 6) on Xen -
3.1 on a AMD Opteron SVM enabled system (blade with 2 dual cores). I
followed the instructions in the user manual to create an image of the OS. I
have included the configuration file that I am using and also information
using xm info. I am a newbie to Xen installation and would really appreciate
help and suggestions.
Following is the error message I get when I try the command xm create -c
xmexample.hvm
Using config file "./xmexample.hvm".
Started domain HVM1
Unexpected error: exceptions.OSError
Please report to xen-devel@lists.xensource.com

HI Mats, Thanks a lot for your reply. I have tried without -c and still the VM doesnt work. I sent the error to xen-developers list since the error message said so, but will also post it to the users list.

That''s very strange, because the call-stack indicates that the second from last call was from "do_console", which I believe shouldn''t be called if you don''t do "-c" - I could be wrong, and I don''t have the source accessible where I am at the mo''. But I would have at least expected the call-stack to be different. -- Mats>Nidhi > > >On 7/14/07, Mats Petersson ><<mailto:mats@planetcatfish.com>mats@planetcatfish.com > wrote: >At 02:56 14/07/2007, you wrote: > >Hi, > > > >I am trying to set up fully virtualized guest VMs (Fedora core 6) > >on Xen -3.1 on a AMD Opteron SVM enabled system (blade with 2 dual > >cores).

Thanks, Mats. I was able to get it working using VNC and then setting up the console display in the guest VM.
