Next, using the same rootfs, I checkout 2.6.26-rc7 and generated a UML guest for it. Looking at the uml/include/config/kernel.release indicated the version of the UML guest as: 2.6.26-rc4-00103-g1beee8d It bootup no problem as well. Next I checkout the 2.6.26 branch (current master), and generated a UML guest for it. Now the guest have the same version as the host - 2.6.26. But bootup with errors: EXT3-fs: mounted filesystem with ordered data mode. VFS: Mounted root (ext3 filesystem) readonly.
