[ovs-discuss] Unable to configure the linux kernel module

[ANAND AKELLA]

Hi Ben,
I'm trying to install the kernel 3.3 package on Utah Emulab  Ubuntu
11.04 node. Is there any specific kernel package we need to install or
else we have to install the complete kernel 3.3. The reason I'm asking
is it takes more than 1 hour to compile the kernel package.

Thanks,
Anand
