After specifying the root_fs it was started booting , but i did not get
the login prompt. The last few boot line messages are as below VFS: Mounted root (ext2 filesystem) readonly. line_ioctl: tty0: ioctl KDSIGACCEPT called INIT: version 2.84 booting EXT2-fs warning: checktime reached, running e2fsck is recommended INIT: Entering runlevel: 5 INIT: Id "c1" respawning too fast: disabled for 5 minutes INIT: no more processes left in this runlevel INIT: Id "c1" respawning too fast: disabled for 5 minutesRegards, Ravikumar Manish Katiyar wrote: Hi, Apart from building the kernel, did you download the filesystem from the UML official page. Once you have downloaded you can run using ./linux ubd0=root_fs mem=512M The second memory parameter is not mandatory, but i find it a good idea to specify otherwise it fails sometimes due to insufficient swap space.
