screenshot showing taking snapshot of the VM
This screenshot is about the RHV Manager complaining about the missing agent on the RHEL 8 guests and shows warning that the snapshot may be inconsistent
This is not just for RHEL 8 guests. My customer is running RHEL 7.5 guests and we're seeing this exact same issue. We have a 3 node RHHI (RHV 4.2 based) deployment in a completely disconnected lab environment. We're seeing the same issue when we try to create a template from a running VM. "Failed preparing template <name> for sealing (VM:<UNKNOWN>)" When we create a template with the virtual machine off, it works fine. We've tried creating (with the machine on) with RAW vs. QCOW2, with and without the memory state and it always fails. Note that this customer is not able to provide logs, SOS output or screen shots. Mark, this is expected behavior, which is documented in the administration guide. See https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/html/virtual_machine_management_guide/Creating_a_template_from_an_existing_virtual_machine Specifically, the note that the VM must be powered off or down Regarding oVirt 4.3.4.3-1.el7 - the bug still seems to be there, cannot create a sealed template. Platform was closed NOTABUG. The best we'll be able to do here is try to ensure that sysprepping happens on EL8 hosts in mixed clusters on CCL 4.3 Bugzilla does not let me add a KCS today, so here it is: https://access.redhat.com/solutions/3914591 And docs bug: https://bugzilla.redhat.com/show_bug.cgi?id=1739583 sync2jira sync2jira I believe this should be a dup of this doc bug on RHV: bz#1739583. If you believe this should be somewhere in RHHI-V specific documentation, please reopen and suggest where exactly. Otherwise, this will be addressed once we switch to RHEL8 based hypervisors. *** This bug has been marked as a duplicate of bug 1739583 *** |
Description of problem: ------------------------ RHEL 8 guest was successfully created with RHHI-V 1.5 environment. While trying to make the template of this RHEL 8 guest with 'Seal Template' option, error was observed with 'Failed to seal the template' from RHV Manager UI Version-Release number of selected component (if applicable): -------------------------------------------------------------- RHHI 1.5 - RHV 4.2.7 - RHGS 3.4.1 How reproducible: ------------------ Always Steps to Reproduce: -------------------- 1. Create a RHEL 8 guest 2. Poweroff the VM 3. Make a template of this guest with 'Seal Template' Actual results: --------------- Failed to seal the template Expected results: ----------------- Successful sealing of template Additional info: ----------------- RHV Manager UI Events: Nov 13, 2018, 1:05:38 PM Failed to seal Template RHEL8_Template (VM: appvm02). --- Additional comment from SATHEESARAN on 2018-11-13 07:57:02 UTC --- Snip from engine.log <snip> 2018-11-13 13:05:35,079+05 INFO [org.ovirt.engine.core.bll.VirtJobCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-71) [78ed563b-9f16-46a7-9ba9-7fcf77864bbc] Command SealVmTem plate id: 'b356d40a-806d-4816-a95f-3d87ee8837a3': job 'fae09b9a-eb4d-4249-b189-b7be2a8ed92c' execution was completed with VDSM job status 'failed' 2018-11-13 13:05:35,083+05 INFO [org.ovirt.engine.core.bll.VirtJobCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-71) [78ed563b-9f16-46a7-9ba9-7fcf77864bbc] Command SealVmTem plate id: 'b356d40a-806d-4816-a95f-3d87ee8837a3': execution was completed, the command status is 'FAILED' 2018-11-13 13:05:36,085+05 ERROR [org.ovirt.engine.core.bll.SealVmTemplateCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-56) [78ed563b-9f16-46a7-9ba9-7fcf77864bbc] Ending comm and 'org.ovirt.engine.core.bll.SealVmTemplateCommand' with failure. 2018-11-13 13:05:37,112+05 INFO [org.ovirt.engine.core.bll.SerialChildCommandsExecutionCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-22) [78ed563b-9f16-46a7-9ba9-7fcf77864b bc] Command 'AddVmTemplate' id: '8c4c86c9-628d-4f58-abff-199f934b922a' child commands '[067114b0-ec4c-4202-8a5e-b1662b1e5c3e, b356d40a-806d-4816-a95f-3d87ee8837a3]' executions were comp leted, status 'FAILED' 2018-11-13 13:05:38,174+05 ERROR [org.ovirt.engine.core.bll.AddVmTemplateCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-29) [78ed563b-9f16-46a7-9ba9-7fcf77864bbc] Ending comma nd 'org.ovirt.engine.core.bll.AddVmTemplateCommand' with failure. 2018-11-13 13:05:38,182+05 INFO [org.ovirt.engine.core.vdsbroker.SetVmStatusVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-29) [78ed563b-9f16-46a7-9ba9-7fcf77864bbc] START , SetVmStatusVDSCommand( SetVmStatusVDSCommandParameters:{vmId='80d9f34e-5615-4ec5-8aeb-4a82b6a70e4a', status='Down', exitStatus='Normal'}), log id: 657e9ea6 2018-11-13 13:05:38,184+05 INFO [org.ovirt.engine.core.vdsbroker.SetVmStatusVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-29) [78ed563b-9f16-46a7-9ba9-7fcf77864bbc] FINIS H, SetVmStatusVDSCommand, log id: 657e9ea6 2018-11-13 13:05:38,193+05 INFO [org.ovirt.engine.core.bll.AddVmTemplateCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-29) [78ed563b-9f16-46a7-9ba9-7fcf77864bbc] Lock freed t o object 'EngineLock:{exclusiveLocks='[654ca84c-62a6-4715-830e-bb7a18667ebb=DISK, RHEL8_Template=TEMPLATE_NAME, 7903571a-5093-4019-9fa5-a3322f76fd9c=TEMPLATE]', sharedLocks='[80d9f34e-5 615-4ec5-8aeb-4a82b6a70e4a=VM]'}' 2018-11-13 13:05:38,210+05 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-29) [78ed563b-9f16-46a7-9ba9-7fcf 77864bbc] EVENT_ID: USER_ADD_VM_TEMPLATE_SEAL_FAILURE(1,324), Failed to seal Template RHEL8_Template (VM: appvm02). </snip> --- Additional comment from Sahina Bose on 2018-11-19 05:00:13 UTC --- Can you clone this bug to RHV?
