Re: [Xen-users] Did anyone succeeded in installing xen 4.0.0 on Debian Lenny?

[Mark Adams <mark@xxxxxxxxxxxxxxxxxx>]

As Pasi says it does work, I am using it to passthrough a nic. Out of your 
options only the xen-pciback.hide on the kernel command line was required for 
me, plus of course the config in the vm.cfg file.

In your xm dmesg does it show that the device was successfully hidden? What do 
you get from xm list-pci-assignable-devices? (sorry that may not be 100% 
accurate command it's something like that)

I did have issues with 1 quad port Gb pci-e card. It would hide correctly but 
the domU would not load it as an interface (I think now maybe because the domU 
was Lenny not tested that theory though). 

Can give you some more detailed config tomorrow if required.
 
Regards,
Mark
