Dear Sir,
Did the following and it fixed the problem.
- Downloaded "linux-3.18.20.tar.xz" from kernel.org
- compiled it using:
ARCH=um make mrproper
ARCH=um make SUBARCH=i386 i386_defconfig
ARCH=um make SUBARCH=i386
- Downloaded "Ubuntu-TrustyTahr-i386-root_fs" and
"Fedora21-x86-root_fs"
Ran the following command:
./linux ubda=Ubuntu-TrustyTahr-i386-root_fs rw mem=512m umid=224
Ubuntu rootfs is not working and then tried Fedora_root_fs.
./linux ubda=Fedora21-x86-root_fs rw mem=512m umid=224
- It is working properly. Now I am getting the console without
any error on UML.
Thanks for your suggestion and help.
Thanks & Regards,
Vijay
