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 minutes

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.
Thanks

Hi all,
I'm reading about UML , in that process i've just built the UML and
tried to run the UML binary 'linux'.
I got the following error message.
Couldn't stat "root_fs" : err = 2
Failed to initialize ubd device 0 :Couldn't determine size of device's file
VFS: Cannot open root device "98:0" or unknown-block(98,0)
Please append a correct "root=" boot option; here are the available
partitions:
