This bug report has Keywords: Regression or TestBlocker. Since no regressions or test blockers are allowed between releases, it is also being identified as a blocker for this release. Please resolve ASAP. I'm also experiencing this problem on Red Hat Virtualization Manager Version: 4.1.7.2-0.1.el7 This is also relevant for 4.2.0-0.0.master.20171013142622.git15e767c.el7.centos Created attachment 1340563 [details]

(In reply to Mor from comment #3) > This is also relevant for > 4.2.0-0.0.master.20171013142622.git15e767c.el7.centos The fix was merged to master on Oct 17th, so it should be included in nightly build 4.2.0-0.0.master.20171018... For 4.1.7 this fis is included in 4.1.7.4 build I think that BZ 1506092 should be a blocker to this bug. It can't tested properly until fixed. (In reply to Michael Burman from comment #6) > I think that BZ 1506092 should be a blocker to this bug. It can't tested > properly until fixed. BZ 1506092 should be a blocker for this bug on 4.2, as 4.1.7.4 not affected. As BZ 1506092 wasn't affecting 4.1.7, only 4.2, this report can be verified with out any blockers or issues. Verified on - 4.1.7.4-0.1.el7 |
Created attachment 1334377 [details] engine.log Job isn't finished and stuck in the engine db. Them image is locked for ever and can't be released. Preview VM Snapshot is failed and engine aware of it, but the job keep running for ever. NO time out. <jobs> <jobhref="/ovirt-engine/api/jobs/19f3e594-a84c-406e-bd0f-5bf681179fc1"id="19f3e594-a84c-406e-bd0f-5bf681179fc1"> <actions> <linkhref="/ovirt-engine/api/jobs/19f3e594-a84c-406e-bd0f-5bf681179fc1/clear"rel="clear"/> <linkhref="/ovirt-engine/api/jobs/19f3e594-a84c-406e-bd0f-5bf681179fc1/end"rel="end"/> </actions> <description>Preview VM Snapshot snap4 of VM VM6</description> <linkhref="/ovirt-engine/api/jobs/19f3e594-a84c-406e-bd0f-5bf681179fc1/steps"rel="steps"/> <auto_cleared>true</auto_cleared> <external>false</external> <last_updated>2017-09-27T10:52:18.730+03:00</last_updated> <start_time>2017-09-27T10:52:16.205+03:00</start_time> <status>started</status> <ownerhref="/ovirt-engine/api/users/586c19dc-00b9-00fa-0364-00000000012f"id="586c19dc-00b9-00fa-0364-00000000012f"/> </job> - Snapshot-Preview snap4 for VM VM6 was initiated by admin@internal-authz. - No MAC addresses left in the MAC Address Pool. - Some MAC addresses had to be reallocated, but operation failed because of insufficient amount of free MACs. - Failed to complete Snapshot-Preview snap4 for VM VM6. - In case of snapshot preview and we need to allocate new MAC for the VM and we have no MACs left, the operation must failed. It is indeed failing and engine aware of the failure, but the job run for ever and stuck in Finalize state. The most worst thing here is that the image got locked for ever! - Steps to reproduce - 1) Master 4.2 2) 2 VMs in cluster 3) MAC pool range with only one MAC address in cluster 4) Start VM1 with 1 vNIC with MAC 'z' 5) Create snapshot from VM1 6) Unplug the vNIC from VM1 and give MAC 'w'(not from the pool) to VM1 and assign MAC address 'z'(the origin MAC) to VM2 7) Try to preview VM1 from snapshot Expected Result - should fail Actual result - Engine failed operation - - Snapshot-Preview snap4 for VM VM6 was initiated by admin@internal-authz. - No MAC addresses left in the MAC Address Pool. - Some MAC addresses had to be reallocated, but operation failed because of insufficient amount of free MACs. - Failed to complete Snapshot-Preview snap4 for VM VM6. But, the job is stuck and image stay locked!
