2.If i create swap file, will it reside in host kernel?

3.Is it possible to create swap partition(disk partition) for UML?

4.I am trying to mount a file from host kernel to guest kernel.....can any

Swapping on a disk partition vs swapping into a file.

Of course - everything on the system resides in the host kernel.

Sure.

host% uml_mconsole <umid> config ubdb /path/to/host/file

UML# mount /dev/ubdb /mnt

skas3 requires a patch to the host kernel, skas0 does not, and will
run on a stock host.

OTOH, some operations are faster on a skas3 host.
