Comment 1 Yaacov Zamir 2020-08-04 06:07:05 UTC

The Jira issue, for book keeping: https://issues.redhat.com/browse/CNV-5823

Comment 2 Filip Krepinsky 2020-08-10 17:06:27 UTC

it seems the support for this should be in master of vm-import-operator already.

@Yaacov It seems the target release of the vm-import-operator fix is CNV 2.5? What version of CNV is going to be released with openshift 4.6? Could we implement this RFE now?

Comment 3 Yaacov Zamir 2020-08-10 17:24:28 UTC

I am planned to reinstall our server today, got stuck on some BZs :-) will upgrade soon.

Comment 4 Yaacov Zamir 2020-08-10 17:27:17 UTC

cnv 2.5 will be released with openshift 4.6,
so if back end will have the feature in 2.5 we can support it in 4.6 UI

Comment 5 Filip Krepinsky 2020-08-10 17:34:51 UTC

cool, if there would be a version mismatch, then any import would fail on unknown fields

Comment 8 Maayan Hadasi 2020-09-30 10:20:16 UTC

I managed to import RHV to CNV fedora32 VM using ceph-RBD storage class, VolumeMode: Block
CNV 2.5.0 / OCP 4.6.0-fc.8

I tested it with same source VM configured as follow:
1. placement_policy is set to <affinity>migratable</affinity> --> Disk Access Mode in CNV side: RWX
2. placement_policy is set to <affinity>user_migratable</affinity> --> RWO
3. placement_policy is set to <affinity>pinned</affinity> (non_migratable) --> RWO

In all cases import was ended successfully.

@Alex 
Based on what you mentioned here: https://bugzilla.redhat.com/show_bug.cgi?id=1864577#c4 I expected that VM import using block/RWO will fail
Was it changed and we can import using ceph-rbd block, either RWO/RWX?

Comment 9 Alexander Wels 2020-09-30 11:16:55 UTC

Hi,

So for ceph-rbd the following 3 combinations will work:
1. RWO FileSystem
2. RWO Block
3. RWX Block
The 4th combination doesn't work.

So your outcome is expected.

Comment 10 Maayan Hadasi 2020-09-30 11:42:35 UTC

Verified as fixed.

Versions:
OCP 4.6.0-fc.8
CNV 2.5.0

I Was able to import RHV VM using ceph-rbd, Block, RWO/RWX
