Re: [Xen-users] domU static IP

[Viswanath Durbha <Durbha.Viswanath@xxxxxxxxxxxxx>]

Hi,

The problem seems to have been resolved by following the instructions given in comment#3 of the bugzilla discussion below:

http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=471#c3

Basically, I modified the ifcfg-eth0 file to add a function that reads /proc/cmdline and sets the parameters to eth0 interface. This is fantastic!! Thanks for everyone who responded to my question.

Thanks,
Vishi
