I have the following machine with ESXi 6.5
1. Intel NUC, latest BIOS, 2 x 1TB Intel 600p M2 SSD
2. ESXi version: 6.5.0 ESXi build number: 5969303
3. Client version: 1.21.0 Client build number: 5724747
On the host, I built a test VM from scratch
1. VM version 6.5
2. Guest OS Windows 2012 R2
3. 2 x 40GB HDD, thin provisioned
On my Windows 8.1 workstation
1. I opened the host client
2. Open the VM
3. Export OVF
I made a few export OVF attempts without success. The guest machine's OVF, and disk-2.vmdk were downloaded without errors, however, disk-1.vmdk couldn't be downloaded. The disk-1 is about 22GB in size on the host, disk-2 is less than 1GB.
When I did it in Chrome, it showed network interruptions
When I did it in IE 11, the exact message was "The disk-1.vmdk download was interrupted."
I stick to IE, when I received the download error, and before I clicked Cancel the disk-1.vmdk download, I inspected the download file size, and I measured this 3 times, the results as follow:
attempt#1, 03/08/17 06:32 AM 10,942,487,040 disk-1.vmdk.908quoc.partial
attempt#2, 03/08/17 09:31 AM 10,942,487,040 disk-1.vmdk.n3pg05j.partial
attempt#3, 03/08/17 10:13 AM 10,942,487,040 disk-1.vmdk.bb66hln.partial
This led me to think if it was download file size limitation - did not find any reference that IE 11 has download file size limitation (https://blogs.msdn.microsoft.com/ieinternals/2011/03/10/file-upload-and-download-limits/)
Had also excluded the download folder from the anti-virus.
Does it seem something to do with the Host Client that is limiting the download file size?
