Proceeding past this point I detach the pci device from the host. I then edit the guest config file as given in the example only to discover that the changes are not saved. it reported that the configuration was edted by opening the configuration in virtsh edit a second time shows that the added <hostdev></hostdev> section was not saved. Perhaps this is because the example provides no context as to where it is nested within the xml file and my placing it directly within the <domain> </domain> tags is invalid. Further, the requirement to set setsebool -P virt_manage_sysfs 1 cannot be met since an SELinux boolean of that name does not exist (apparently it was renamed to virt_use_nfs). The reference I am using is found at: http://www.linuxtopia.org/online_books/rhel6/rhel_6_virtualization/rhel_6_virtualization_chap-Virtualization-PCI_passthrough.html However, I do not think that I can recommend it based on my experience. -- *** E-Mail is NOT a SECURE channel *** James B.
