Hi I had Xen 2.x running peacefully on FC4 .. sigh. Yesterday I upgraded to FC5 and also downloaded and installed the new Xen version 3.x from xensource.com .. I installed via the precompiled tarball. My grub entries loook like this: title Xen 3.0 (Fedora/XenLinux 2.6) root (hd0,4) kernel /xen.gz dom0_mem=260000 module /vmlinuz-2.6-xen root=/dev/sda6 ro console=tty0 module /initrd-2.6.15-1.2054_FC5.img boot My /etc/fstab looks like this: /dev/sda6 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 /dev/sda7 swap swap defaults 0 0 ... Fedora is installed on a SATA hard disk, partition /dev/sda6 Xen boots and then soon after reports a kernel panic and after a few seconds reboots .. I was unable to get the messages before the last screen but managed to capture the last messages on screen .. reported below. ...
