Hi All,

I am running xen and 2 para guest OS on top of this.
>From xen documention i read that it has split driver architecture for net, block and tpm driver (and some other driver also).

I want to know that how i can see these backend modules in dom0 and domu ?

When i do ps -aef in dom0 then it gives 
#ps -aef
root      4658    19  0 Mar09 ?        00:00:00 [blkback.6.sda1]
root      5302    19  0 Mar09 ?        00:00:01 [blkback.7.sda1]

indicating 2 instance of blkback modules in dom0 for the two guest domain respectively.

BUt i am not getting such infomation for netback, i think it should be same as blkback ? right???

Now if i talk about frontend guest domain then i dont get any such modules ( not as processes nor as  module from lsmod ).

I am bit confused how these modules are visulized on the system.

I would appreciate any document link  that can help to unerstand this concepts.

Thanks,
Trilok
