They either hang or time out with an error that they can't connect to a vbd backend device. This happens after the GRUB menu, so the bootloader is in fact accessed. The strangest thing is, that by starting xend and creating the same domain with xm create works 100%, but after stopping xend afterwards I cannot create any more domains with xl, because udev gets messed up between xm and xl. Obviously I shouldn't, and don't want to mix the two. Another strange thing is that xl create on this same domain works fine on kernel 3.5... But I can't use kernel >=3.5, as the PCI USB passthrough is broken. So I am sitting with a catch-22: use kernel 3.5/3.6 and have xl work for all domains, but can't use my HVM Windows machine that needs PCI passthrough for VGA and USB, or use only kernel 3.3.4, but can't start PV domains unless I use xend. Any suggestions would be appreciated! If I need to send configs or logs, please let me know. Kind regards, Andi
