Hi:
When I try to map my PCI NICs to DomU, I encounter this
error in domU:
Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v1.8.5b
(Feb 9, 2009)
PCI: Enabling device 0000:00:00.0 (0000 -> 0002)
PCI: Setting latency timer of device 0000:00:00.0 to 64
bnx2 0000:00:00.0: Cannot map register space, aborting.
bnx2: probe of 0000:00:00.0 failed with error -12
I use the same kernel between Dom0 and DomU, and the same
driver can works well in Dom0.
Tested in Xen-3.2.0, if I add the product id ‘14e4:1639’
into /etc/xen/xend-pci-permissive.sxp and rebuild initrd.img with “--preload
pciback”, the BCM NIC can works well in DomU.
But when I make the same configuration in Xen-3.3.1, it
doesn’t work.
Does somebody meet the same problem?
All feedback is welcome.
