Hi,
we can't import some OVA VMs into oVirt, that was previously exported in oVirt.
Further investigations and testing showed, that in some vm.ovf files the last closing tag is missing ( </ovf:Envelope instead of </ovf:Envelope> ).
Intense testing showed the following occurrence:
on test DC (4.4.10.7-1):
- about half of the VMs have that problem (about 9 VMs)
- VMs where the export is working properly are ok, no matter how often i do export
- VMs who's vm.ovf is wrong stay that way, no matter how often i do export
on production DC (4.4.10.7-1):
- all VMs have that problem (49 VMs)
- an imported "good" VM formerly exported on test DC, now have a wrong vm.ovf too after re-exporting on production DC
- vm.ovf of all VMs stay incorrect, no matter how often i do export
on develop DC (4.5.4-1):
- the only VM have that problem (1 VM)
- vm.ovf of VMs stay incorrect, no matter how often i do export
Environment:
all DC have independent hardware and are built exactly the same way with the same components
oVirt is with hosted-engine
test and production:
oVirt: 4.4.10.7-1
engine OS: Cent OS Stream 8
host OS: RHEL 8.7
develop:
oVirt: 4.5.4-1
engine OS: Cent OS Stream 8 (latest updates till September 1st)
host OS: RHEL 8.8 (latest updates till September 1st)
Is that a known problem?
Nope
Is there a way to fix this?
We use the same components that we use for OVAs also for writing OVFs of snapshots and for writing domain XMLs so I doubt the problem is on the ovirt-engine side (as we would have seen more severe issues)
We store the OVF in the OVA with a Python script that runs on the host so I'd suggest to look for a message that starts with "writing ovf:" in its log [1] to see whether the script was provided with the complete XML from ovirt-engine
If the complete XML was provided, you can change the pack_ova.py script on the ovirt-engine side to debug why it's not stored properly in the tar (OVA) file
regards, Lars
