[Xen-users] PCI-Passthrough

[Ian Murray <murrayie@xxxxxxxxxxx>]

Hi,

I am trying to get a PCI network card working through PCI pass-through.

When I start the relevant domain, I get the following message. Using 3.4.2 from 
GitCo repository on Centos 5.4. Dom0 and DomU's kernels report they are 
2.6.18-164.11.1.el5xen. This is the std Xen kernel from CentOS.

When I try to start the related DomU domain, I get this.

Error: pci: 0000:01:06.0: non-page-aligned MMIO BAR found.

A bit of googling says I should put something in my kernel of Dom0's boot line, 
e.g. 

module /vmlinuz-2.6.18-164.11.1.el5xen ro root=/dev/VG1/LV0 pci=nomsi 
cpufreq=xen pciback.permissive pciback.hide=(01:06.0) reassign_resources 
reassigndev=00:01:06.0


But this hasn't help. Any suggestions would be welcome.

Thanks,

Ian.
