[Xen-users] CONFIG_XEN_PHYSDEV_ACCESS in domainU

Hi,

We have been using Xen for several months now and it works real great (we 
have it running on Intel SR1300, Intel SR2300 and PowerEdge 1850).

Now we need one unpriviledged host to be able to access directly 2 PCI cards 
(RocketPort and modem on PowerEdge 1850):
As soon as I set CONFIG_XEN_PHYSDEV_ACCESS=y for a domainU, I can no longer 
start the virtual host, there is nothing on the console but I get the 
following from the xend log:

How can I get more clues to what''s going on ? Anybody able to get a
similar
configuration to work ?

Thanks for any help.

Patrice

Same here, tried with several different combinations of kernel-configs.. Ive
also asked (about 4 month ago) if anybody has a working kernel-config with
CONFIG_XEN_PHYSDEV_ACCESS enabled, but no response :-(

Re: [Xen-users] CONFIG_XEN_PHYSDEV_ACCESS in domainU

I think I ran into a similar problem. I had to also enable the domain
0 config option to get the kernel to work at all. I''m not sure if
that''s expected or if this is a bug as I''m relatively new to
Xen.

Once I did that however, my PCI cards worked great in a domU.
