Re: [Xen-devel] domU guest for xcp 0.1.1

[Ritu kaur <ritu.kaur.us@xxxxxxxxx>]

Hi Pasi,

I am able to use xen/stable kernel in domU(debian lenny) and lspci lists the device(i am testing pci passthrough). however, when I compile my driver in domU I get 

struct net_device has no member named open
struct net_device has no member named stop
struct net_device has no member named hard_start_xmit
...

I need to compile my driver in domU and load it in order to use the nic from domU. Inputs appreciated.

Thanks

Hello Ritu,

I don't have experience with XCP specifically, but normal compiled pvops-kernels work fine for me with Debian lenny domU's.
