From what Jeff and Antonie said, I realized that I need to have UML kernel running to use mconsole and uml_swap and root_fs should be in the same dir in the host fs. So here is what i did -
1. Created uml_swap in the host fs in the same dir as root_fs (actually root_fs is in /opt/ and I have a symlink to it in /root/uml/ and so uml_swap is in /rrot/uml). And then I tried - (a) ./linux ubd0=root_fs ubd1=uml_swap mem=128M con0=fd:0,fd:1 con=xterm eth0=tuntap,tap0,FE:F0:00:00:00:01,192.168.0.254 umid=vm001 Boot log - ubda: unknown partition table ubdb: unknown partition table [EMAIL PROTECTED] ~]# cat /proc/meminfo | grep Swap SwapCached: 0 kB SwapTotal: 0 kB SwapFree: 0 kB [EMAIL PROTECTED] ~]# (b) ./linux ubda=root_fs ubdb=uml_swap mem=128M con0=fd:0,fd:1 con=xterm eth0=tuntap,tap0,FE:F0:00:00:00:01,192.168.0.254 umid=vm001 Boot log- ubda: unknown partition table ubdb: unknown partition table [EMAIL PROTECTED] ~]# cat /proc/meminfo | grep Swap SwapCached: 0 kB SwapTotal: 0 kB SwapFree: 0 kB [EMAIL PROTECTED] ~]# Note that I created uml_swap by doing - dd if=/dev/zero of=uml_swap bs=1024 seek=$[ 1024 * 1024 ] count=1 Then when UML is booted in a new host console I did a - [EMAIL PROTECTED] linux-2.6.21]# uml_mconsole vm001 config ubd1=uml_swap ERR Device is already configured If swap is configured, then why do I see the unknown partition table message and why cat /proc/meminfo | grep Swap shows 0 swap space ? I promise that I'll read more upon ubd(which I think is causing the problem), but can anyone please tell me why I don't see swap space in UML? Or what I'm doing wrong.
