Hi, Some time ago i asked a question about the Pacifica/VT features. I''ve been thinking about it some more now. What i would want is to run the host system using a x86_64 (ie. AMD64) platform and then run native 32-bit platforms as guests (windows). AFAIK this should be possible as AMD64 is just an extension to the x86 features of a CPU. Does anyone has comments about this?

Are you meaning a x86 XenU on a x86_64 host system?

>Are you meaning a x86 XenU on a x86_64 host system?An _unmodified_ x86 domU on an x86_64 host. 64 bit Xen doesn''t support the 32-bit Xen interface, so explicitly Xen-native 32-bit guests can''t run on it even though fully-virtualised unmodified guests can. i.e.: 32-bit host: 32-bit Xen-native guests 32-bit host w/VT or w/Pacifica: 32-bit Xen-native guests, 32-bit unmodified guests 64-bit host: 64-bit Xen-native guests 64-bit host w/VT or w/Pacifica: 64-bit Xen-native guests, 64 or 32 bit unmodified guests Cheers, Mark> >Regards, > >Matthijs ter Woord > > > > >----- Original Message ----- >From: "Anthony Liguori" <aliguori@us.ibm.com> >To: "Matthijs ter Woord" <matthijsterwoord@gmail.com> >Cc: <xen-users@lists.xensource.com> >Sent: Monday, November 21, 2005 3:46 PM >Subject: Re: [Xen-users] Pacifica/VT again > > >> Matthijs ter Woord wrote: >> >> > Hi, >> > >> > Some time ago i asked a question about the Pacifica/VT features.
