Hi, Jeff Could you help to point out the difference between this bug and bug 1067576? Is the script in comment 1 is the scenario we need to test and verify for this bug? Thanks, Qunfang (In reply to Qunfang Zhang from comment #3) > Hi, Jeff > > Could you help to point out the difference between this bug and bug 1067576? > Is the script in comment 1 is the scenario we need to test and verify for > this bug? > > > Thanks, > Qunfang Hi Qunfang, This bug is for RHEL6.6, while the other bug is a z-stream candidate for RHEL6.5. But RHEL6.6 will need a patch as well.

But RHEL6.6 will need a patch as well. Hi, Jeff Thanks for the reply. But I'm still confused. Usually we will have a bug for rhel6.6, and then after it's approved by PM, it will be cloned to a new bug for rhel6.5-z. Currently the sequence is just opposite and both the bugs have "rhel6.6.0?" flags. Could you help check and confirm? Also help fix me if it's wrong. Thanks! Qunfang |
Created attachment 868778 [details] Script to reproduce relative pathname bug with just qemu-kvm and qemu-img Script to reproduce relative pathname bug with just qemu-kvm and qemu-img Attached is a script to reproduce this bug with just qemu-kvm, and qemu-img. This can be seen via either live snapshots, or image creation with qemu-img. This script will do the following: 1) create test directory 2) create a qcow2 base image 3) launch qemu-kvm with qmp over localhost tcp 4) attempt to create 80 live snapshots with a relative pathname, to parent directory and then back into the test directory 5) run qemu-img, create a different set of 80 snapshots off the same base image. 6) kill the process started in step #3 All you should need to edit in the script is the executable path for qemu and qemu-img. The test directory is left after the script runs, with the created snapshots and an output log, for later examination. Expected outcome: -355: All snapshot created successfully (live and via qemu-img) -415: First ~24 snapshots succeed, those after that fail Any fix should restore it back to -355 parity. If you edit the script to create 150 snapshots instead of 80, you will see -355 fail as well.
