Re: [Xen-users] PCI Passthrough problems (Cannot access network but e1000 loads fine)

Hi,

I do not get anything strange here. This is from the dmesg on domU

Is there anything special I need to do for /etc/network or
/etc/network-scripts/ifcfg-eth0 apart from what I did to get it
working for vif interface.

I used extra='noirqdebug' in my config file and my domU does not boot after :
[340110.616654] Entered sys_init_module.
[340110.621535] usbcore: registered new driver usbfs
[340110.621572] usbcore: registered new driver hub

I already have extra='xcons=tty' - does that get overidden?

Please help.

Regards,
Asim
