Description Eduard Benes 2011-07-28 10:16:28 UTC
After running one of audit-tests for testing PCI Passthrough (iommu -> pci_passthrough sanity_detach_1) there are following AVC recorded in the final report. I guess it could be either allowed it or dontaudited it? The test fails to detach a network device. This is not always reproducible and also the tested functionality does not seems be affected either.
