xend never finishes starting at boot, in the host os. My pc never finishes booting. If I boot the "kernel-xen" kernel, I get "xend starting" then nothing. If I boot the "kernel-xen0" kernel, I get a bit further: "bridge firewalling registered", and "peth0 setting promiscuous mode" Not sure if it's relevant, but the kernel also tells me on boot that "bug: 8254 timer not connected to IO APIC"
