Unable to export OVF template

Problem

Unable to export OVF template

Attempting to export an OVF template from ESXi 6.5 to host client, fails with the following message:

From google chrome: Failed - Network error

From IE: The disk-1.vmdk download was interrupted

Before this error, I tried to export the VM from vCenter, and it was even worse, it was stuck. And after a long period, it shows another error message.

Solution

Updated: Check the last section for a workaround.

The solution is quite simple, Use Firefox!

I was insisting over and over again with Google Chrome and IE, and it seems that these two web browsers have problems when downloading large files.

At the moment of writing this, I used Firefox version 58.0.1 (64-bit) and worked like a charm.

[EDIT: 26/04/2019]:

Google Chrome seems to work well now with large files from a while on. Recently I tested under Google Chrome Version 73.0.3683.103 (Official Build) (64-bit) and vSphere 6.7 U2 to download an OVF file over 10GB, and it went well. If you still have some issues, check the options below or the last section for a workaround.

Follow these basic best practices when exporting a VM (OVF format):

  • Remove snapshots from the VM
  • Unplug ISO files attached to the VM
  • Use a direct connection to the ESXi host, vCenter has always been kind of buggy with this.

Still having issues?

Use the VMware OVF tool! If you are still having issues with exporting an OVF template from an ESXi host to your local machine (PC), go to the following blog post for a workaround using the VMware OFV tool. It is easy!

  1. In my case, the UI was just doing nothing. Turned out your last comment helped, the machine still had a CD with an ISO file but that didn’t exist anymore on the datastore, and that was the reason. Changing the CD back to host device, and it would export fine. Thx!

I was switching my storage array, so I migrated the VMs from that old datastore/storage to a new datastore/storage. The old datastore was shared by 3 ESXi hosts, no cluster. After migrating the VMs and unmount/delete the datastore, it was still presented in two of the ESXi hosts and was marked as inaccessible.

WinSCP VCSA

Unable to Access the VCSA 6.7 via WinSCP

One of the many and easiest ways to get the logs from the ESXi hosts and vCenter Server Appliance (VCSA), is accessing directly to the files directory using tools such as WinSCP, which helps to transfer the files between a local and a remote computer ( Ex. VCSA). I never have had issues with the ESXi hosts and WinSCP, however, trying to access the VCSA is a different story.
