Hello, People seem to want to pci-passthrough just a single port from dual-port NICs. It doesn't seem to work anymore, and Xen complains like this: http://lists.xensource.com/archives/html/xen-users/2009-12/msg00267.html "Error: pci: improper device assignment specified: pci: 0000:04:00.0 must be co-assigned to the same guest with 0000:04:00.1, but it is not owned by pciback." With "disable FLR" patch it works OK: http://lists.xensource.com/archives/html/xen-users/2009-12/msg00338.html That user is using the first port of the NIC in dom0, and passing through the second port to domU. Can we have an option in Xen guest cfgfile to disable flr? -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
