Actually I have just realized that the vkbd feature couldn't possibly have been backported to xen 4.1.1. In fact I didn't even add any vkbd devices for HVM guests in XL in xen-unstable yet. Of course this was to avoid situations like this one. So my guess is that when you use "vfb" in an HVM guest config file you cause xend to create a vkbd device that is without backend. A PV on HVM guest would try to connect to it but it wouldn't get any response back so it would timeout. The solution to this problem is to avoid using vfb in the config file. I strongly hope that the config file you showed us before is not generated by libvirt somehow. If it is we need to file a bug against libvirt. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
