Hi, i use Virtual Box and want to try XEN in it. All is possible but i cannot not install a self made OS. "HVM" Problem. Normally Virtual Box use VT-technologie but i don''t now XEN can use them still at time? Virtual in Virtual ist this possible with VB or something els VirtualMachine-Software? Great day and fell fine hackinchen _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I think the real problem is not how, is why ? Virtual Box ---> desktop and workstation Xen --> server regards yves hakinchen a écrit :> Hi, > > i use Virtual Box and want to try XEN in it. > All is possible but i cannot not install a self made OS. > "HVM" Problem. > > Normally Virtual Box use VT-technologie but i don''t now XEN can use > them still at time? > Virtual in Virtual ist this possible with VB or something els > VirtualMachine-Software? > > > Great day and fell fine > > hackinchen > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users >-- Yves-Gaël Chény Directeur technique 44 Boulevard des Pas Enchantés 44230 St Sébastien sur Loire Tel : 02 40 97 62 67 - 08 73 77 24 91 GSM : 06 98 58 41 55 http://www.tranquilitsystems.com/ yves-gael.cheny@tranquil-it-systems.fr Tranquil IT Systems .

Ok, i think that xen couldn''t run into a virtualbox or only very partially .. ;) regards yves -- Yves-Gaël Chény Directeur technique 44 Boulevard des Pas Enchantés 44230 St Sébastien sur Loire Tel : 02 40 97 62 67 - 08 73 77 24 91 GSM : 06 98 58 41 55 http://www.tranquilitsystems.com/ yves-gael.cheny@tranquil-it-systems.fr Tranquil IT Systems .

Most virtualization technologies do not pass thru the VT or SVM capabilities of the processor to the guest OS (in your case, your Xen installation). So as far as Xen knows, it is running on a machine that does not support VT or SVM. You can check this by doing `cat /proc/cpuinfo` and looking for vmx in the flags area. You should be able to install PV guests though. If you are wanting to just experiment with Xen, doing it in VirtualBox is alright. But I would not recommend it for a regular Xen installation. Hope that answers your question. Mike Lovell _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

These sort of things doesn''t really yield any values. Two days before, I had a test running xen dom0 as a vmware guest and running domu in that dom0. Paravirtualized guest can start successfully. The end result was that, performance was worst than sluggish that I could ever imagine, random crashes, random hangup and etc... None of the virtualization technology is designed for nesting, so no one can get any value out of it. --Sadique>> >> >> Great day and fell fine >> >> hackinchen > Xen will probably work inside of VirtualBox but I doubt that you will > be able to get a HVM guest to work.

As far as I know, Xen hypervisor needs direct access to the real hardware, so you won''t be able to run it inside a virtual machine. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I see, thanks. Ok, now i''m moving xen to another PC. One last question, It is possible to run a domU with a 2.2kernel? Or it can be done only with 2.6-xen kernel? Because i need to run an old machine with 2.2 kernel. Witch has some old modules that i can''t make them work in a new kernel. thanks On Mon, Aug 9, 2010 at 9:30 PM, Edson Marquezani Filho < edsonmarquezani@gmail.com> wrote:> As far as I know, Xen hypervisor needs direct access to the real > hardware, so you won''t be able to run it inside a virtual machine. >-- *-----* *Juan Pablo Lopez Bergero* *Web: www.lopb.com.ar* *Cell: 15-3957-3455* * * _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

So, you can''t expect a very good performance, as you would have in PVM mode (paravirtualized), which is the point where Xen becomes more interesting and competitive, by the way. Obs: I''m not aware of a xen modified kernel of 2.2 or 2.4 generation. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Well, i thinks this will not work. Because i need pci pass through. And it does not work in full virtualizated mode.
