Re: [Xen-devel] Q on netfront/netback driver

[ravi kerur <rkerur@xxxxxxxxx>]

Hi Konrad,

I thought Citrix Xenserver is based on Xen kernel and it inherited all of Xen mgmt cli and other tools. 

I have downloaded source code from http://www.citrix.com/lang/English/lp/lp_1688623.asp
and have looked into product cd 1(in which I found netfront and netback source code), product cd 4(probably tools). Unfortunately don't find anything related to /xen/tools/hotplug... Any inputs?

Thanks
-RK

You definitly will need to modify the udev rules and potentially a bunch
of shell scripts in: xen/tools/hotplug/Linux

If you mean the source code of the kernel, look in
drivers/xen/netback/* files.

Ah, I was incorrect. It is CONFIG_XEN_NETDEV_BACKEND.
