RE: [Xen-users] 32bit guest on 64bit host

[Maurício Ramos <Mauricio.Ramos@xxxxxxxxxxxxxxxxxxxx>]

Hello, using a debian 4 live CD we are able to boot. It is maybe something 
mandriva related (tried 2 versions: 2007 and 2009). We will try with others 
like Ubuntu and maybe CentOs.

I do not what is PV or HVM but I am trying to create a full virtualized 
mandriva 2009. In addition, we have other 32 bit VMs running in another server 
(same OS, Xen, etc.) and they are Linux distros much older.

Are you trying to create PV or HVM guest?

Do you have HVM support in your CPU/BIOS?

What does "xm info" say about capabilities? Do you see hvm listed?
