[Xen-users] usb pass through + xen 4.0.1 + centos 5.5 + pvm
Hi, Is there any definitive wether USB passthrough works on Xen 4.0.1 and Centos 5.5 on a PVM really works or not? Seems like by the many posts I''ve read, it doesn''t. Any one mind enlightening me. - Brian _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Pasi, So I would need the pvops kernel (2.6.32) on both dom0 and domU just to pass a USB port? Seems like it would be easier to use KVM as passing a USB port seemed alot easier according to a quick google. - Brian On Jan 21, 2011, at 2:59 AM, Pasi Kärkkäinen wrote:> On Thu, Jan 20, 2011 at 11:02:26AM -0800, Brian Krusic wrote: >> Hi, >> >> Is there any definitive wether USB passthrough works on Xen 4.0.1 and >> Centos 5.5 on a PVM really works or not? >> >> Seems like by the many posts I''ve read, it doesn''t. >> >> Any one mind enlightening me. >> >> > > For PV domUs you need to use pvusb. > pvusb requires *drivers* in both the dom0 kernel, and in the domU > kernel! > (in addition to pvusb support in Xen). > > -- Pasi > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
