I did try to run user mode linux for centos3. This is my setting:
Host Distribution: rhel3
Host Kernel: 2.4.21-27.ELsmp
Guest Kernel: 2.4.27-1um SMP
CentOS distr: 3 (
I get my centos 3 rootfs by installing distribution in a Fedora Core 3 UML, i.e., I boot up off a pre-built Fedora Core 3 rootfs, then mount centos file system and install in there. The installation seems OK, though I see a lot of warnings with selinux. And after the installation, I can chroot to new cent os file system.
But when I boot up off the new centos 3 rootfs, it hangs at 'Configuring kernel parameters [OK]'. Does anyone know why?
