Hi List, i have the Xen-kernel from backports.org running on my debian stable machine. It works quite well but as i reboot a DomU with a physical NIC assigned to it (using the "pci="-option) it won't restart. I did a little googling and came across the following error: http://lists.xensource.com/archives/html/xen-users/2006-05/msg00107.html But this don't seem to be my exact problem since the error message in xend.log is different. Is this a bug in xen or am i missing something. Any hint's or help would be greatly appreciated. Maybe i'm just too dumb to get it right. I've attached my config file and a stacktrace to this mail. Thanks very much in advance Sebastian ------------- config file ------------- kernel = "/boot/vmlinuz-2.6.16-2-xen-686" ramdisk="/boot/initrd.img-2.6.16-2-xen-686" memory = 64 name = "wwwserver" #vif = [ '' ] pci = ['0000:02:05.0'] disk = [
