Hi list, I'm building my first usermode linux system, using a howto from the Gentoo site. (http://www.gentoo.org/doc/en/uml.xml)
When I booted linux, it hung(*) because it couldn't find any modules, so I went back and built and installed modules target, mounted the rootfs as loopdevice and copied all of the fresh /lib/modules/x.y.z to /mnt/loop/lib/ modules. Nothing is mentioned about modules in the howto so I just had to second-guess it... (*) I assumed it hung because on the host system I saw many many shells spawned by the usermode system So now the modules are there, but the real problem, the endless spawning of shells, still persists. This is what I see on the host system: [host system] ps ax <snip the usual processes> 4890 pts/0 T+ 0:00 linux [/sbin/init] 4896 pts/0 T+ 0:00 linux [/bin/bash] 4904 pts/0 T+ 0:00 linux [/bin/bash] 4914 pts/0 T+ 0:00 linux [/bin/bash] 4926 pts/0 T+ 0:00 linux [/bin/bash] 4932 pts/0 T+ 0:00 linux [/bin/bash] <snip couple of thousand of identical lines...> 25661 pts/0 T+ 0:00 linux [/bin/bash] 25665 pts/0 T+ 0:00 linux [/bin/bash] 25669 pts/0 T+ 0:00 linux [/sbin/init] 25671 pts/0 T+ 0:00 linux [/sbin/init] 25673 pts/0 S+ 0:00 linux [/sbin/agetty] 25676 pts/0 T+ 0:00 linux [/sbin/init] 25678 pts/0 S+ 0:00 linux [/sbin/agetty] After a long wait, the xterms appear and I can login fine, and networking works fine, too. But the uml guest load is steadily above 1, the system is dead slow and the host shows between 1000 and 4000 'linux ......." processes equal to the above list. The host system isn't starved for resources, it's a dual xeon machine with 1GB ram. Are all those shells normal ? I kind of doubt it... Am I nearly there, or is there something really wrong here ? Google didn't find anything useful, nor did the faqs et al.
