When a VM from the older compatibility version is imported, its configuration has to be updated to be compatible with the current cluster compatibility version. This enhancement adds a warning to the audit log that lists the updated parameters.

oVirt gerrit 102652 0 'None' ABANDONED engine: Block importing of VMs of newer Clusters 2020-09-29 14:17:13 UTC

Internal Links: 1829916

Description Germano Veit Michel 2019-08-14 03:29:33 UTC 
Description of problem:

It was previously discussed that the engine can only import/convert VMs that originate from the cluster levels it supports. For example, a 4.3 engine can only convert/import VMs from 4.1, 4.2 and 4.3 even if it and vdsm support the storage domain version (V3, V4, V5..) used to move the VMs.

If this is correct, please add a warning or block importing VMs from incompatible cluster levels, and suggest a stepped migration (going through a lower version first) for the VMs to be properly converted.

The necessary data seems to be on the OVFs:

# xmllint -format 8e709281-aae8-49e1-b5a0-a7f6b7e646ba.ovf | grep ClusterCompatibility
    <ClusterCompatibilityVersion>4.3</ClusterCompatibilityVersion>

Speaking of additional cl 4.4 things...
Comment 2 Michal Skrivanek 2019-08-15 00:56:26 UTC 
For which imports? OVA should already be handled.

Data Domains and Export Domain (if you decided to keep it).
Comment 4 Michal Skrivanek 2019-08-15 10:27:41 UTC 
it's not an additional thing, it's basically just bug 1678007.
Export domains are going away.

This sounds great. So having a VM imported from older version should not be an issue, once this bug is implemented?


Should we close this bug as a duplicate ?

To synchronize, from our discussions Shmuel first needs to verify that updating the version to the cluster's compatibility version works. If so then we can mark this as a duplicate and abandon the patch for this issue.
Comment 7 Ryan Barry 2019-08-21 10:51:05 UTC 
It will still be necessary to warn or block if the conversion/update cannot be assured, but that's part of a complete solution for the other bug
Comment 8 Andrej Krejcir 2019-12-09 14:15:41 UTC 
This RFE will be implemented as part of Bug 1678007.

Verified on RHV 4.4.1-1 and RHEL 8.1 hosts. 

I ran all test cases from the attached Polarion requirement and all the tests passed.
