An error occurred while opening a virtual disk. Verify that the converter server and the running source machines have a network access to the source and destination ESX/ESXi hosts

Hello, I am trying to P2V server and get this error.

Converting from physical host to vcenter.

I see it successfully creates snapshot and fails right after it.

Thank you in advance.

From the source physical machine try telnet esxi-hostname 902.

What is the standalone converter version that you are using ?

Try not to convert multiple VM's to same ESXi host at a time. If you are using Standalone converter 5.x, you should probably select the destination as vCenter.

Can you upload the converter diagnostic information.

[mummonth]

Telnet works fine, port is open.

[rcporto]

Ok, if possible, attach the diagnostic logs.

v 5.5.2

I am converting only one VM, not multiple.

Yes, I am selecting vCenter as a destination.

You know it's weird ... when I exported logs fist time it went well. I am attaching it to this message.

But now when I try to export logs it gives me an error "the diagnostic package cannot be retrieved from vmware vcenter converter standalone. Error: could not generate vmware vcenter converter standalone server diagnostic file"

And he save only converter-gui files in this log now.

Ouch! Thank you, sir!

That's a not an easy requirement, because they are in different datacenter.

I will work with my networking team on it.

After opening ports described in this document everything worked fine for us:

VMware KB: Required VMware vCenter Converter 4.x/5.x ports

Thank you very much!
