Cannot export OVAs

olivierlambert

That's our official doc: https://xen-orchestra.com/docs/xoa.html#via-a-bash-script

Maybe it's not updated somewhere else?

@olivierlambert Curl is from my old notes, so my mistake... It's also still in the older blog posts:

Thanks, fixed in both links

@Andrew @sluflyer06 I am exporting VM since yesterday without problems

Did you make a yarn or npm install after updating code ? we rollbacked a dependency

Andrew

@florent I still see the problem.

I did a cache clean:

yarn cache clean
npm cache clean --force

and then did a XO source code update and rebuild. OVA export starts downloading at 2MBytes/sec and then fails.

I also see the problem on XOA (standard deploy):

- node: 18.12.1
- npm: 8.19.2
- xen-orchestra-upload-ova: 0.1.4
- xo-server: 5.111.1
- xo-server-telemetry: 0.5.0
- xo-server-xoa: 0.19.0
- xo-web-free: 5.114.0
- xoa-cli: 0.35.0
- xoa-updater: 0.45.1

Download starts at 10MBytes/second and runs for a while before it fails.

@Andrew if this is in a XOA, could you open a support tunnel and allow me to try to download the same ova ?

Andrew

@florent Open.

So, I did not see the failure on a 60G VM, but I do see it on the 120G VM. Both use up memory but it does not hit critical on the smaller VM.

florent

@Andrew thanks you for the tunnel I found something

@sluflyer06 can you tests this branch ?
https://github.com/vatesfr/xen-orchestra/pull/6800

fbeauchamp opened this pull request in vatesfr/xen-orchestra

closed fix(xo-vmdk-to-vhd): wait for OVA stream to be written before reading more data #6800

Andrew

@florent That works much better for me! I was able to quickly OVA export VMs that failed before. Memory usage on XO was normal and did not grow. Download speed was good most of the time at 30-35MBytes/sec. It would pause occasionally but toward the end it picked up to 50-60MBytes/sec.

@Andrew Exporting all my large VM's worked on that branch.

Andrew

@sluflyer06 Today, XO source master has been updated with that fix.

sluflyer06

@Andrew Awesome.
