Snapshot is "Locked" - Can't do anything with the VM
by Ivo Rütsche 18 May '16

18 May '16

Hi oVirt List We have the problem, that two of our VM's have "Locked" snapshots and we can't go forward. From 10 VM's which we move from one store to another, we have problems with 5 of them to delete the snapshots. But with a lot of luck, the snapshot was always on the dedicated Swap-Disk, so we just have to remove the whole disk and create it again as new. Because we replace all the filers, we have to move the VM's arround. The move itself runns fine, but deleting the snapshots doesn't work sometimes. I found a lot about our problem, but I can't find any solution, which works an our environment. Our setup: - 3 Solaris filer with NFS exports for the hosts for the vm-images - 8 hosts (oVirt 3.6 / Centos 7.2.1511) - The engine host is located outside of the DC, connected via VPN At the moment, one of the "problem-VM" is productive, the other should become productive in the next days, so we focus us to the 2nd VM, because we can play arround with them. The other one is startet up, but i have no idea, what happens, when i shut them down... This is the status today of VM, which is not productive at the moment: - VM Status: Down - Snapshots OK: 2 - Snapshots Locked: 1 - In the snapshot tab, everything is grayed out (Create, Preview, Commit, Undo etc.) - No active tasks are displayed Error message when i try to start the VM: "Cannot run VM. The VM is performing an operation on a Snapshot. Please wait for the operation to finish, and try again." Something about the history of this VM: 1. We start the disk move from filer1 to filer3, totaly 4 drives, everything was fine 2. Deleting snapshots, i think one or two runns fine 3. Deleting the 2nd or 3rd snapshot runs two days without an end 4. Rebooting the Engine 5. No task anymore in the Tasks list 6. The status of the snapshot is "Locked", die Disk of this snapshot becoms "Illegal" and red 7. Shutdown the VM - no luck, i can't start it again --> "Cannot run VM. The VM is performing an operation on a Snapshot. Please wait for the operation to finish, and try again." 8. We move the disk back from filer3 to the filer1 9. The status of the snapshot is "Locked", die Disk of this snapshot becoms "OK" and green ...but i can't delete the snapshot or starting the VM :( Today, i copy the image files to a dedicated KVM host, which is not involved in the oVirt environment and i merge the image manualy together: qemu-img convert -p -f qcow2 804ffcc3-446f-4c56-ba99-ab90c7951a6f -O raw Merged1 I mount the image and everything fine, all the changes from the last two days are now in a base image. I try to remove the whole disk in oVirt, but i still got the error message, that i have to wait. So for me, the next step is to create a new VM and migrate everything manualy, this will work, but can't be the solution for the other VM, which is productive and it have the same problem.

AAA LDAP timeout
by Dominique Taffin 18 May '16

18 May '16

Hello! We do have a rather large LDAP which does take some time to answer. Using oVirt and AAA LDAP extension, I do run into timeouts. running "ovirt-engine-extensions-tool --log-level=FINEST --log- file=tool.log aaa login-user --profile=abc --user-name=xxx" fails with: [...] LDAPSearchException(resultCode=85 (timeout), numEntries=0, numReferences=0, errorMessage='A client-side timeout was encountered while waiting 60000ms for a response to search request with message ID 3, base DN [...] ldapsearch itself takes approx 2 minutes. Can the timeout of 60000ms be configured somewhere? I could not find anything in the documentation... thank you and best, Dominique

RemoveDiskSnapshots error's on engine log
by Ivo Rütsche 18 May '16

18 May '16

Hi List At the moment, we replace a filer and we have to move the VM's to another filer. We have a lot of problems with it. Sometime we have to restart the engine, sometime we have to move the image arround and sometimes we don't have a chance to remove the snapshots. When the VM is running, most of the time the snapshot remove never starts.

How to migrate un-migratable VMs?
by Nicolas Ecarnot 18 May '16

18 May '16

Hi, Some VMs are doing high guest-memory writes (mainly files and mail servers, but not only), so migrations are reproductively failing. I found some info here : https://bugzilla.redhat.com/show_bug.cgi?id=919201 that confirm what I was fearing. This BZ is aging from dinosaurs times, so I was wondering now we're in the 3.6.x age and 4.x coming, are there advices one may give to migrate those verbose VMs? I guess increasing the allowed page memory is not a correct answer as it will fill as before. Any thoughts? -- Nicolas ECARNOT

Do you use ovirt-engine-reports?
by Yedidyah Bar David 18 May '16

18 May '16

Hi all, We are considering dropping ovirt-engine-reports in 4.0. Some of its functionality will be added in a new feature called "Dashboards", see [1]. Do you use Reports? How important it is to your setup? [1] https://bugzilla.redhat.com/1324860 Best regards, -- Didi
