[libvirt] Problems accessing ESX using libvirt

I was forwarded the following query relating to v2v: === There are no firewalls between the hosts and the ESX firewall is configured to allow all incoming & outgoing connections. The "virsh -c 'esx://elabhost011.xxx/' list --all" command also fails in the same way as the virt-v2v command. When I run the 'virsh list' command it doesn't prompt for a username/password as in the example below. If I run tcpdump on the ESX host, when 'virsh list' is run, I see the packet arrive from the test box and a reply sent back, only these two packets are sent between the hosts: 09:51:20.205524 bwyhs0020p.xxx.56436 > elabhost011.xxx.16514: S 338(0) win 5840 <mss 1460,sackOK,timestamp 1214177495 0,nop,wscale 7> (DF) 09:51:20.205544 elabhost011.xxx.16514 > bwyhs0020p.xxx.56436: R 0:9 win 0 (DF) The problem is there is nothing listening on port 16514 on the ESX host, hence the "Connection refused" message. Should the connection be using the TSL port as opposed to a 'ESX' port? === The user is using libvirt 0.6.3-20.1.el5_4. Unfortunately I'm not intimately familiar with how the libvirt ESX driver magic works. Can anybody shed any light?
