Open Stack

 Hi,

 I'm testing PCI passthrough features on Havana (single node installation).
I've installed OpenStack on CentOS 6.4 using EPEL.
The pci_passthrough_filter doesn't seem to be able to get the object 'host_state.pci_stats'. 
Is it a bug?

 Thanks,
 David

 Here is the information of the test environment:

1. /etc/nova.conf

pci_alias={"name":"test", "product_id":"7190", "vendor_id":"8086"}
pci_passthrough_whitelist=[{"vendor_id":"8086","product_id":"7190"}]


scheduler_available_filters=nova.scheduler.filters.all_filters
scheduler_available_filters=nova.scheduler.filters.pci_passthrough_filter.PciPassthroughFilter

scheduler_default_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,CoreFilter,PciPassthroughFilter
