Hello. I try to use UML. My guest kernel is sys-kernel/usermode-sources. I read both howto - on gentoo-wiki(http://gentoo-wiki.com/HOWTO_User_Mode_Linux) and gentoo docs(http://www.gentoo.org/doc/en/uml.xml). But when i run my uml i have this error:

After some googling i found that i need reverse x86-64 support patch. But if i reverse this patch, i think that i could not run UML on AMD64. Somebody can give me a solution?

Kernel (?) called init with invalid arguments.
You seem to have a lot of interesting command line arguments. Perhaps starting with only two basic arguments ubd0 and ubd1 could help and add others once you booted your UML successfully.
Also, I'd try to re-create the root_fs as instructed in Gentoo UML guide. |
