This is bad because libvirt reported that the device was successfully destroyed, but it didn't actually go away. There are really two bugs here. One is the failure to destroy the vHBA, which is a dup of 593995. The destroy operation goes to look up the parent, finds "computer", realizes that it can't issue a destroy operation to it, and fails. I have already submitted a patch upstream to fix this problem. The other bug is that nodeDeviceDestroy does not set its return value correctly on failure. I have a patch which I will be submitting upstream today. The upstream patch was ack'd and I pushed it earlier today, commit d3e43bad98e3f95408203859bb4165f3b9b10d5b This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. libvirt-0_8_1-10_el6 has been built in RHEL-6-candidate with the fix.

Thanks... Manas This event sent from IssueTracker by jkachuck issue 1068533 Thanks for the verification; this fix should be in snap 7. Red Hat Enterprise Linux 6.0 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you. |
