The only time I've seen this is when I screwed up the console config (like the Xen kernel thinks it should be using serial rather than vga or vis-a-vis) Look at the console (or on the kernel line, com1=) options in the grub config and compare them to the one that works. If the grub config is about the same, I would hook up a null modem and see if I could boot it off the serial console (which is my preference anyhow) You could try forcing it to use a serial console (my preference anyhow) here's what my grub snippit looks like: title CentOS (2.6.18-53.1.21.el5xen) root (hd0,0) kernel /boot/xen.gz-2.6.18-53.1.21.el5 dom0_mem=512M com1=115200,8n1 module /boot/vmlinuz-2.6.18-53.1.21.el5xen selinux=0 ro root=/dev/md0 console=ttyS0,115200n8 module /boot/initrd-2.6.18-53.1.21.el5xen.img Of course, that might not be it. The grub config is still the first place I'd look- I'd make sure to remove any splash screens or 'quiet' options. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
