Hi,
My environment is as below:
Hardware: Dell R210
NICs: Broadcom NetXtreme II BCN5709/5716 (w/o FLR)
Xen: xen 4.1.2
Kernel: 3.6.32.57 (final version of xen community)
Distribution: Centos 6.2 (upgraded to above kernel)
When I added iommu=soft to domU kernel boot line, the PCI passthru-ed NICs can
be UP and RUNNING. Otherwise, omit iommu=soft option would make the passthru-ed
NICs only UP but not RUNNING. Anybody can explain why and how can I use hardware
iommu instead?
Thanks,
HUAXIANG FAN
