<![CDATA[ova export not functional]]>Hi, I have been evaluating XCP-ng and Xen Orchestra (Community Edition) for a couple of weeks and I'm really enjoying it. I have one issue that I can't seem to find a way to solve, however. I can import VMs that I have previously created using VMware with no problems and I can create new VMs in Xen Orchestra. But when I try and export using OVA (because there are times when I still need to use a VM I have created locally on my laptop to interface with devices that I can't connect to a server) the file downloads without any issues but I cannot get it to work with VMware or VirtualBox. VMware just fails to import with an unknown fault. VirtualBox gives me an error

Error reading OVA
(VERR_TAR_BAD_CHKSUM_FIELD)
2a0bc2d2-6ea6-449e-a847-e7ec69776889-image.png

I've tried extracting the OVA to OVF format and it also failed.

I have also tried exporting just the vdi file in vmdk format and recreating the VM locally using VMware workstation and that also failed.

I'm really eager to use this product more but I can't really proceed unless I have a reliable way to also use the VMs on a local machine. Any help would be greatly appreciated.

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.

found it , it's the keys for UEFI

and there is for the video card

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

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

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 )

  • 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.

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

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

I am downloading the image right now and will look for a solution

So I have also tried using the OVA with a Ubuntu machine and had the same error (I have uploaded that OVA file to the drive folder).

I did what you suggested with the XVA file and yes it successfully exported (with compression disabled - the only one I tried) and then imported back into another instance of XCP-ng. I have included the XVA file in the drive folder also.

I hope this helps to get to the root cause of the error.
