[uml-user] UML console not coming

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

Hi All,
    I am Vijay, working as software engineer in Tejas Networks Bangalore, India.

    I downloaded the following:
    - UML Kernel image v3.18 for i386 32 bit
    - root filesystem for Ubuntu-14 and Fedora21

 My system configuration:
 - Ubuntu-14.04 32 bit
 - Kernel : 3.19

 After downloading ran the following command:
 ./kernel ubda=Ubuntu_root_fs

 After sometime, Got the following error continuously:
 - getmaster : no usable host pty device

 I am unable to get the console.

 I searched in internet about the solution but no luck. Tried with Fedora root_fs also but no success.

 Please help.

Regards,
Vijay
