Hi all, I was wondering if anyone has run Xen on top of Xen in the following scenarios and did it work: 1) Xen-Paravirtualized on top of Xen Intel-VT (I hope this would work out of the box) 2) Xen Intel-VT on top of Xen-Paravirtualized (I don''t think this would work out of the box) Thanks, -Rick _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Even if you could run the hypervisor inside an hvm guest to get 1) to work, I would suspect the performance would be abysmal. I tried loading WIndows Virtual PC 2007 inside my Xen WIndows XP guest. The configuration steps worked fine, but as soon as I tried to run the Virtual PC guest, my Xen Windows guest became unresponsive. (Maybe Xen/qemu-dm was trying to emulate every instruction of the Virtual PC guest? :-) Some people on this list report being able to run Xen under Vmware. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Xen can''t emulate the presense of VT if it''s not already there, so your option 2 won''t work, sorry.> Even if you could run the hypervisor inside an > hvm guest to get 1) to work, I would suspect the performance would be > abysmal.

Not great but actually pretty good. The fact that it''s doing paravirtualisation rather than two nested layers of full virtualisation probably makes a lot of difference here! I actually use Xen-on-Xen to do development, with my unstable development Xens running in HVM domains on top of a nice reliable host Xen :-) Cheers, Mark -- Push Me Pull You - Distributed SCM tool (http://www.cl.cam.ac.uk/~maw48/pmpu/) _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
