RHEL5.4 vt-d: Assigning a PCI device using virt-manager/virt-install fails
Last modified: 2009-12-14 16:03:02 EST
+++ This bug was initially created as a clone of Bug #499267 +++
Just tested virt-manager's device assignment with the following steps:
* Run virt-manager, open an existing guest and go to the details tab
* Click "Add hardware", choose "Physical host device" and click "Forward"
* Choose the appropriate device from the drop down list (e.g. "00:19.0 Interface eth0 (82566DM-2 Gigabit Network Connection)")
* Click "Forward" and "Finish"
and it failed with:
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/addhardware.py", line 571, in finish
File "/usr/share/virt-manager/virtManager/addhardware.py", line 607, in add_hostdev

raise RuntimeError(_("Could not detach PCI device: %s" % str(e)))
RuntimeError: Could not detach PCI device: 'PCIDevice' object has no attribute 'dettach'

Just tried with virt-install --host-device and got the same error

Okay, the problem turns out to be that VirtualHostDevice._nodedev is a NodeDevice, not a virNodeDevice yet we do this:
We need a comprehensive fix which doesn't throw away the virNodeDevice in NodeDeviceParser.lookupNodeName(), but I think we should temporarily disable this dettach/reset code for F11 GA and the test day tomorrow

Created an attachment (id=342658)
Call detach/reset on the correct object
Seems to have done the job, since choosing an arbitrary pci entry in 'virsh nodedev-list' and passing to --host-device managed to lock my machine up :)

Looks good to me

Built into python-virtinst-0.400.3-8.fc11.

The patch for this is upstream here:
Fix is very low risk, and without it, PCI device assignment doesn't work via virtinst + virt-manager. Since PCI assignment support in the tools is one of the big features for 5.4, we should probably get this in.
Fixed in python-virtinst-0.400.3-2.el5. Closing as NEXTRELEASE, since this bug (and the affected functionality) has not existed in any released package as it was brought in by the rebase.
