Hey, Anyone tried before, is it successful? Also, Is it possible to use the CPU VT inside Xen if it is running inside VirtualBox? I want to setup such env. for testing purpose. Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You can do xen PV inside a xen HVM though so who knows?

I''ve tryed it, but it resulted in my whole system rebooting itself when I reboot the VM. Really crazy. First, xen boot freezes somewhere. Then I reboot the VM and after I try to boot it again the whole system reboots.

Re: [Xen-users] Install Xen on VirtualBox?
For tests... Xen works on top of VMWare! ;-) 2009/7/12 Giorgenes Gelatti <giorgenes@gmail.com>> I''ve tryed it, but it resulted in my whole system rebooting itself when I > reboot the VM.

I have done this as well, but it is somewhat limited as I don''t believe you can pass Intel VTx/VTd cpu instructions through to a second virtual layer. Just a heads up. Please correct me if I''m wrong, but I was not able to run HVM guests in a hypervisor-within-hypervisor scenario. /mark Date: Sun, 12 Jul 2009 20:28:02 -0300> From: Thiago Camargo Martins Cordeiro <thiagocmartinsc@gmail.com> > > For tests...

I have been able to run this: Xen Host -> HVM Guest running Xen -> PV Guest But not HVM inside HVM. I''d guess, and this is only a guess, that there''s a lot more than not being able to pass CPU instructions through multiple hypervisors, but that is certainly a big deal. I''ve run inside of VMWare guests as well, but only to one layer: VMWare Host -> VMWare Guest -> Xen Also, even when I could get this to work and actually boot, the performance was so bad that all systems involved were pretty much useless... -- Milton Berle - "If opportunity doesn''t knock, build a door." - http://www.brainyquote.com/quotes/authors/m/milton_berle.html _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I used it to compile and test various Xen and kernel versions. If you have time you might want to try that. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
