Well, sources for 2.6.9 include support for UML (but it's outdated), what you have installed is likely a binary kernel. And that is not reusable for UML, which requires a completely different binary (thought it's obtained from the same sources). > I have installed also 2.6.8.1-kernel to my computer because some > programs need it, and they don't work in newer kernels.

The host kernel is the one you select with grub, the guest one is the UML kernel, normally named like "vmlinux-2.6.12", which you run as a normal program to launch UML, like: ./vmlinux-2.6.12 ubd0s=root_fs_image Well, you have 4 option, for obtaining the guest kernel: *) downloading a binary one from somewhere - please an up-to-date version. Or compiling from source, from best to worst: *) using 2.6.12 + -bs11 patches from my homepage: this will give you the a very stable UML version. *) using vanilla 2.6.9 (not 2.6.9-1.667, which contains patches from Fedora which probably don't play well with UML) or it with its latest -bs patch. Vanilla 2.6.9 doesn't work well on 2.6.9/10 hosts, because they have a "bug" for debugging. *) using 2.6.8.1 with patches from UML site (unrecommended - less stability). For compiling: *unpack the kernel and apply patches; *then do make defconfig ARCH=um * then make xconfig ARCH=um or make menuconfig ARCH=um for changing options. * then make ARCH=um and use the resulting "linux" or "vmlinux" binary. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
