ova export not functional

Gheppy

I have the same thing with OVA of windows VM, on linux VM all is ok.
Import is done on VirtualBox 7

florent

it reminds another bug with bigger VM

@gasky @Gheppy Do you have any VM with less than 8Gb data ? can you try exporting it in ova and loading it in virtual box ?

Gheppy

Linux, yes. Windows has by default 15Gb+, maybe core one has less

EDIT:
Windows 2022 Core, it works
Size on VHD,

Rocky Linux 9, it works
Size on VHD

gasky

Sorry, I don't have any VMs that small. But if I understand correctly from @Gheppy it seems the issue is related to the VMs size?

olivierlambert

It might be this. @florent is the opportunity to make them test your branch

florent

@olivierlambert yes, as soon as my branch is working as intended

For now I can generate a valid tar (with pax header) , but virtual box don't like it

florent

@gasky @Gheppy

could you try this branch : fix_re_re_ova_export (PR is https://github.com/vatesfr/xen-orchestra/pull/7183/files ) ?

don't forget to do a yarn install before relaunching xo, since we updated a dependency

fbeauchamp opened this pull request in vatesfr/xen-orchestra

closed fix(xo-vmdk-to-vhd): improve compatibilty of ova with disk bigger than 8.2GB #7183

Gheppy

Windows 22h2 ova is exported fine. The import goes to the end only if:

it is not set to EFI boot by default
the type of Operating System is on Other and the version is Other/Unknown
video is under 16Mb

Linux ova export is fine. The import goes to the end with the same missconfiguration.

After the settings are done everything works fine.
Size of ova

florent

@Gheppy yes

at least if fixes import \o/

I am creatig card in the backlog to improve the import. Could you extract the ovf file of the windows ova ( rename it to tar and extract it) , and send it to me or post in in the forum ( it should not contains any confidential information )

Gheppy

this is the metadata.ovf

@Gheppy could you get us an ovf file generated by vmware ?
it would help us find the right fields to use

Gheppy

I don't use VMWare but if you give me some time ( one day ) I will install a server with ESXI and I will do an export.

florent

@Gheppy said in ova export not functional:

I don't use VMWare but if you give me some time ( one day ) I will install a server with ESXI and I will do an export.

no worries I 've got one in my lab, I will just have to create the VM

florent

@Gheppy
found it , it's the keys for UEFI

      <vmw:Config ovf:required="false" vmw:key="firmware" vmw:value="efi"/>
      <vmw:Config ovf:required="false" vmw:key="powerOpInfo.standbyAction" vmw:value="checkpoint"/>

and there is for the video card

      <Item ovf:required="false">
                <rasd:AutomaticAllocation>false</rasd:AutomaticAllocation>
                <rasd:ElementName>VirtualVideoCard</rasd:ElementName>
                <rasd:InstanceID>8</rasd:InstanceID>
                <rasd:ResourceType>24</rasd:ResourceType>
                <vmw:Config ovf:required="false" vmw:key="useAutoDetect" vmw:value="true"/>
                <vmw:Config ovf:required="false" vmw:key="videoRamSizeInKB" vmw:value="16384"/>
                <vmw:Config ovf:required="false" vmw:key="enable3DSupport" vmw:value="false"/>
                <vmw:Config ovf:required="false" vmw:key="use3dRenderer" vmw:value="automatic"/>
                <vmw:Config ovf:required="false" vmw:key="graphicsMemorySizeInKB" vmw:value="262144"/>
                <vmw:CoresPerSocket ovf:required="false">1</vmw:CoresPerSocket>
              </Item>

we should be able to parse them ( from a virtual box/ esxi export) and add them in XO export

Gheppy

I am glad for this.
Is it published in git?
I will want to test it .

gasky

I'm sorry this is a bit over my head but I'm glad to see that you have found the issue. I assume that it will become available in a Xen Orchestra update in the near future? I'm keen to try it out when it does. Thanks

florent

@Gheppy I only identfied the data , I didn't write any code for now

florent

@gasky thank you for signaling this and helping us identifying the cause

gasky

Thank you for responding and helping. Please let me know when there is a solution to test out as I will be eager to try it. Thanks

gasky

@florent I was recently able to test the .ova export again and I was pleased to find that it worked without the errors we had been experiencing. I'm not sure if this is something that I should be putting in a new topic but the only thing now stopping me is that for some reason I cannot get the network drivers to work on a brand new Win10 VM. I exported a working Win10 VM from my local VMware workstation. I then imported it into XCP-ng using the latest version of Xen Orchestra and it worked as expected. I then tried exporting as .ova from Xen orchestra without installing Citrix drivers (and then tried a test with the Cirtrix drivers installed), but after importing back into VMware I couldn't get any network options to work except a 3rd party USB to Ethernet adaptor.

Thanks in advance if you have any advice.
