At this point, the RHEL5 guests (I'm working on that distro first) won't boot. Here's what I'm getting: ----- Going to boot Red Hat Enterprise Linux Server (2.6.18-8.el5xen) kernel: /boot/vmlinuz-2.6.18-8.el5xen initrd: /boot/initrd-2.6.18-8.el5xen.img Started domain guru1 rtc: IRQ 8 is not free. rtc: IRQ 8 is not free. i8042.c: No controller found. Red Hat nash version 5.1.19.6 starting mount: could not find filesystem '/dev/root' setuproot: moving /dev failed: No such file or directory setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! ----- BTW, the GRUB config was edited to specify /dev/xvda1 as the root partition on the kernel command line. After modifying the initrd image in the guest to not load some drivers, to load the xenblk.ko driver, add the xenblk.ko driver and change the device ID in the resume mkrootdev command, I get this: ----- Going to boot Red Hat Enterprise Linux Server (2.6.18-8.el5xen) kernel: /boot/vmlinuz-2.6.18-8.el5xen initrd: /boot/initrd-2.6.18-8.el5xen.img Started domain guru1 rtc: IRQ 8 is not free. rtc: IRQ 8 is not free. i8042.c: No controller found.
