Re: [Xen-users] DomU Direct Hardware access

["William Man" <billybahlah@xxxxxxxxxxx>]

Note, you may/will need to recompile the xen kernel and modules to support your hardware.  As the domU kernal and modules will not have the support.  Alternatively, you can try and use the dom0 kernel and modules.

 

I use xen 2.x , can anyone say if this is still possible in xen 3.x?

 

Thanks
