Just to add to my previous question, I am planning to mak= e changes to netfront and netback drivers and hence needed clarification on= that.

In addition, I had another question on interfaces a.k.a &quo= t;vif" created when domU's are installed, I am unable to figure ou= t which part of Xen code is involved in this. Any pointers will be very muc= h appreciated.

Hello all,

I am trying to understand when and how netback and netfro= nt drivers gets instantiated and does netfront exist in domU's?
I do see the drivers available in following directory in dom0 but nothing = in domU...

=A0$ pwd
/lib/modules/2.6.18-128.1.6.el5.xs5.5.0.496.1012xen/kernel/= drivers/xen

$ ls
pciback=A0 scsiback=A0 scsifront=A0 sfc_netback= =A0 sfc_netfront=A0 sfc_netutil=A0 tpmback

However, I do not see the= drivers listed when "lsmod" is executed on dom0 or domU.

Inputs appreciated.

Thanks
-RK
