So a month ago, I had managed to get a working DomU running on Xen 4.4 with a Radeon 6450HD and a 1x PCIe USB card that had a keyboard and mouse hanging off it, to create a virtual desktop workstation. Not content to let sleeping dogs lie, I installed some package updates (holding kernel and dependent packages at the version I had). Something in the updates, possibly udev-related, broke the USB card pass-through... it no longer registered as a USB card in either the Dom0 or the DomU (and no drivers loaded for it). Tonight I decided to try reseating the card. When I booted the machine up again, I found I had no networking. After some digging, I discovered that my motherboard's ethernet was now occupying the PCI ID that had been used by the USB card. I've moved the USB card to a new slot so my network is now back and the USB card shows up as a USB card (at least sometimes ... haven't identified circumstances yet). After some more fiddling around, I discovered that mixing pciback arguments in grub and in the initramfs modules can create a bit of a mess (namely, updating grub lines has no effect). So, question 1 ... is there any reasoning for using initramfs modules vs. grub configs for something like pciback? Question 2 ... any guidance to be had on passing a PCIe USB card? Or should it "just work"? -Robert _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
