Evidently I should be using http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Host_Configuration_and_Guest_Installation_Guide/chap-Virtualization_Host_Configuration_and_Guest_Installation_Guide-PCI_Assignment.html Which I had looked for but google apparently does not report. I had to search the RedHat web site using their search interface to locate it. The other site purports to be a rhel6 essentials book. Nonetheless, while the inconsistencies of the previous documents are resolved in this new reference the example edit of the virtual guest configuration still fails to provide a context for the insertion: # virsh edit guest1-rhel6-64 <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x000' bus='0x03' slot='0x00' function='0x0'/> </source> </hostdev> Where does this go inside the rest of the guest configuration? <domain type='kvm'> <name>inet08.harte-lyne.ca</name> <uuid>6409d721-cfcf-2169-f65e-8f583b685f58</uuid> <description>Inet08 [216.185.71.28] virtual hosts: none</description> <memory>4194304</memory> <currentMemory>4194304</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64' machine='rhel6.2.0'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none' io='native'/> <source dev='/dev/vg_vhost01/lv_vm_inet08.harte-lyne.ca_00'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </disk> <disk type='block' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='hdc' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' unit='0'/> </disk> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <interface type='bridge'> <mac address='52:54:00:bf:e9:ac'/> <source bridge='br0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <target port='0'/> </serial> <serial type='dev'> <source path='/dev/ttyS0'/> <target port='1'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <input type='tablet' bus='usb'/> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes'/> <sound model='ich6'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </memballoon> </devices> </domain> I have tried placing the <hostdev> tags after the <devices> tag but the changes simply disappear. -- *** E-Mail is NOT a SECURE channel *** James B.
