I upgraded my system from FC3 to the -devel branch. Have the following Xen rpms installed: kernel-xen0-2.6.10-1.1155_FC4 kernel-xenU-2.6.10-1.1155_FC4 xen-2-20050222 I can boot the main (domain-0) kernel. All seems well. When I try to start domain-1 (which has it's own root and swap partitions) it starts up and then just reboots. The last few lines of dmesg are: ... Initializing IPsec netlink socket NET: Registered protocol family 1 NET: Registered protocol family 17 md: Autodetecting RAID arrays. md: autorun ... md: ... autorun DONE. kjournald starting. Commit interval 5 seconds EXT3-fs: mounted filesystem with ordered data mode. VFS: Mounted root (ext3 filesystem) readonly. Freeing unused kernel memory: 128k freed Warning: unable to open an initial console. SELinux: Disabled at runtime. SELinux: Unregistering netfilter hooks Restarting system. xm list (from another window) shows that the domain is shutting down: node-dom1 4 64 0 ---s- 1.6 9604 Anyone have any clues or should I ask on a more Xen specific list?
