SOLVED Cannot export VM in .ova file
-
So i can export VM in .xva format, but not .ova as it gives me an error.
Is it a bug that has been resolved or is it ongoing issue.
Please note, I do not use XOA as this is a sealed network and i have no need for it, so using it is not an option.
Please advice.

Suggest that you supply additional details, such as --
- Version of CH / XCP you are running
- Is your system fully patched?
- Are you using Xencenter / XCP-ng Center to perform the export? If so, what version?
- Provide the exact error message you are receiving
- etc
P.S. I would mention that there are tools to convert between various file formats, but will refrain due to your "sealed network" comment
-
I'm not seeing any connection between using XO and a sealed network
There's people using XO in production in sealed network.Anyway, OVA export via XCP-ng Center is using "transfer VM" mechanism, which is not very reliable.
I would suggest, in your case, to export VM disks in VHD.
Also, it's hard to assist without knowing what do you want to achieve in the end.

Ok, using XCP-ng Center 7.6.1 x64 to perform an export from a system. The .xva is presently stored on USB, thus portable.
Core system is 7.6, fully patched (not sure how i can find out if otherwise).
Error message is simple "Failed to Export".
The reason why I need .ova is because i need to check a few things on that VM, and usually do it via oracle, thus the end conversion is .vdi, however, virtualbox easily converts .ova file, so for me more important how i can format to .ova from .xva, and why the system doesnt do it itself as intended.
***Update:
So just updated the XCP-ng Center to the newest version of 20.03.00, and still get the same error on export of .ova

How can I export VM disks in VHD? This is the first time I'm hearing about that option. Please explain.

You still haven't posted what that error is.
When you export to OVA you need to make sure to configure the network correctly in the export wizard.
If you have multiple vlans on the server you have to select the correct one and so on. -
In XO it's trivial, just clicking on VM disk button called "export". You can also do it with
xeCLI. -
This is the error sting from the log:
2020-03-19 09:20:01,261 ERROR XenAdmin.Actions.AsyncAction [27] - System.Exception: Failed to export. ---> System.Exception: Failed to transfer virtual disk I:\xx\d7e6a6e0-f362-4c26-8df7-de9fea5fc1ca.vhd. ---> System.Exception: Failed to start the Transfer VM. ---> XenAPI.Failure: There was a failure communicating with the plug-in.

Sure, but why cant you guys make it "trivial" in XCP-ng Center? You praise XO so much, but one, it comes with limitations, 2nd its another 3rd party software and 3rd to get full capability it has to be paid, and lastly in order for it to be up to date you need it to have internet access given the license etc.
In short, when you build a closed end system its best to take in what you know or can open and double check. I like XCP-ng and I think you guys have done great job and will hire your system admin in the future but for now certain things have to be achieved and I prefer less systems and those few to work as stated.
Thus, when you mention xe CLI export, it there a tutorial one can view to see the steps?

@dan2462 Don't know what's causing the error but you can export the VHD by ssh:ing to your server or selecting "Local Command shell" on the console and running the following
xe vdi-list xe vdi-export uuid=the-uuid-of-your-VM filename=filename.vhd format=vhdMake sure the location you're saving to has enough space for the file.
If you have curl installed on your VirtualBox machine you can run
curl -u root:your-xcpng-root-password -X GET "server-name-or-IP/export_raw_vdi?vdi=your-vdi-uuid&format=vhd" -o filename.vhdon it.

Thank you. I will be exporting the file remotely from a machine in datacenter to a local machine via network.
In the past, as I used XCP-ng Center, I just plugged a USB and export .xva to USB directly.
Now, what would be the line command for the above but .ova.
I got the xe-list and xe export, but what would be the next line to command. I'm not very good a command line on cent/redhat. Would I need to mount remote storage usb etc. Please advice, meanwhile thank you much for assistance so far.
-
About the error, to you knowledge does the system utilize any ports different from the one it uses for .xva? Could be a networking issue as its quite tight.
Or perhaps, can it be some form of limitation of the memory and power allocated to machine itself.
Would really like to find out if i'm the only one that has the same issue, or to be exact to find the root of it.

I don't think you can do a CLI export to ova.
You couldn't in 2015, at least
https://discussions.citrix.com/topic/361151-how-to-export-to-ovaovf-with-command-line/If you absolutely need ova you have to try and figure out why there's a communication failure.
My guess would be something network related, like a firewall between the XCP-ng server and your XCP-ng Center PC.
Or you're not using the correct setting on the Network page.Someone said "To solve it I simply had to choose an unused static IP on the same subnet as the Network Management Console where the server pool resides."
I don't know what ports the transfer uses and a quick google search didn't show anything either.
-
wait... vhd would work too, doesnt have to be just ova.
I tried running a sniffer on the network and saw no requests on any ports from the system other than whats in use, thus same networking layers are used as for .xva.
So i just drilled ssh access to the machine, so would like to do it via cli, if you can perhaps just share with me the rest of command line to move it to remote storage location such as usb, would greatly appreciate it.
xe vdi-list xe vdi-export uuid=the-uuid-of-your-VM filename=filename.vhd format=vhd ......? -
Hi!
Let me clear some things.

Because XCP-ng Center is not maintained by Vates, it's only community maintained. We discourage usage of it because there's only one person maintaining it on his freetime, @borzel : he's kind to do this, but he's alone. If you want to assist him and improve XCP-ng Center, go ahead.
It's far less 3rd party than XCP-ng Center which is mainly a clone of XenCenter for Citrix.
Also, Xen Orchestra is fully Open Source. So your statement about licensing is just plain wrong 3 times: If you don't want to pay, you can. If you have a paid license, it works offline too. You can also use XOA Free.
In short, when you build a closed end system its best to take in what you know or can open and double check. I like XCP-ng and I think you guys have done great job and will hire your system admin in the future but for now certain things have to be achieved and I prefer less systems and those few to work as stated.
I strongly recommend Xen Orchestra for a lot of reasons: XCP-ng team is working closely with Xen Orchestra, allowing new features to be added both in server and client. We can test it extensively interactions between those two. It's also completely independent from Citrix choices, which is far better.
We have plans for a XO Lite client that will be embed on XCP-ng, so we can remove the last use case for XCP-ng Center.

@dan2462
Plug the USB stick into your XCP-ng server and rundmesg | tail # You should see "sdb: sdb1" or something similar at the bottom of the screen mount /dev/sdb1 /mnt cd /mnt # Make sure you've mounted the correct device and partition : df -h . # You should see that it's the expected USB sizeIf that's the case run the xe commands to save on the USB.
When that's done you runcd /root sync umount /mntThen it's safe to remove the USB

Thank you. Unfortunately, that machine is in datacenter so dont have physical usb access.
Nevertheless, I found a way to do the conversion. Seems as XenConvert 2.3.1 is capable of doing it, however, its only that version that does it, the rest are all different.
Therefore, issue resolved for conversion, but i'm still wondering if im the only one that had that issue or is it quite common given the system version I have to xcp and the center.

Hi Dan2462, I would like you to go for the following steps. In the star just choose the virtual machine and pick the option that says File > Export to OVF. Now add a name for the OVF file and mention a directory in which you need to save it. Here mention if you want to export the virtual machine as an OVF, a folder with individual files, or as an OVA, a single-file archive. At the end press Export to start the procedure of OVF export. This step will take some time and a status bar lets you know about the progress of the export process. Apart from that, https://appuals.com/export-import-vm-oracle/ this website would be really helpful for you in getting to know much more about it. I hope that by following these steps you would be able to resolve this issue.

Sorry for grave digging here, but since this answer ranks pretty high in the Google results, I thought I might add a possible solution:
During the export wizard in XCP-ng Center, you're being asked for the network configuration of the Transfer VM. As for my observations, two things are pretty vital here:
- The network you choose to place the Transfer VM's virtual interface in must be reachable from your computer/XCP-ng center.
- Enter a static IP configuration, DHCP has never worked for me, even though a DHCP server is running in the selected network.
Hope this helps some!
