> But it will work on F15 if you have a recent kernel update. > > Michael Young The Xen manual says that I need something similar to this in grub.conf (I have legacy grub): title Xen 3.0 / XenLinux 2.6 kernel /boot/xen-3.0.gz dom0_mem=262144 module /boot/vmlinuz-2.6-xen0 root=/dev/sda4 ro console=tty0 What is not clear if I need a special kernel set as "module", or my original vmlinuz-2.6.41.1-1.fc15.x86_64 would suffice? My working setup is title Fedora (2.6.41.1-1.fc15.x86_64) root (hd0,0) kernel /boot/vmlinuz-2.6.41.1-1.fc15.x86_64 ro root=UUID=fbb9744f-0226-4665-b377-74522399f301 rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us nomodeset rhgb quiet nouveau.modeset=0 rdblacklist=nouveau initrd /boot/initramfs-2.6.41.1-1.fc15.x86_64.img I rewrote it to title Fedora (XEN) root (hd0,0) kernel /boot/xen.gz dom0_mem=262144 module /boot/vmlinuz-2.6.41.1-1.fc15.x86_64 ro root=UUID=fbb9744f-0226-4665-b377-74522399f301 rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us nomodeset rhgb quiet initrd /boot/initramfs-2.6.41.1-1.fc15.x86_64.img But then Grub said that a linux kernel should be loaded before initrd. Yes I feel that this is more a Grub than a Fedora Xen question but I hope somebody can answer here. - Gergely -- xen mailing list xen@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/xen
