Re: [uml-user] UML console not coming

[Vijay T. <vi...@in...>]

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
