Cam, It's another error. Now there is an issue with esxi server name – 'nssesxi04-mgmt'. It must be the same as appears in vcenter. A screenshot of vcenter tree would help. Please note, there is no need to double escape the URL.

The KVM node (RHEL 7.2) has virt-v2v 1.28.1, though I've also tried using Fedora 23 which has 1.32.4. The details are: vCenter server: nssesxi-mgmt Datacenter name: North Sutton Street esxi server which runs the VM: nssesxi-mgmt04 folder name: Systems VM name: wvm2 cluster name: nssesxi I tried via the 'Import' option in the oVirt GUI, and put the details above in, and after thinking about it for a while, it returns a 500 internal server error. As I'm authing against AD, I put my username as cam@ARDA. I have attached the log (gzipped). I've also tried via the command line, and the result is much the same. I did post the below to the libvirt-users mailing list but have not had a response, so I thought I'd see if anyone here might know what is going on. Unfortunately, spaces were put in the name of the datacenter, so I escape them with %20 So the final URI is constructed as: vpx://<DOMAIN\user@<vcenter_server>/<folder>/<datacenter_name>/<esxi_server> <vm_name> The error I get is: # virt-v2v -v -x -ic vpx://ARDA%5ccam@nssesxi-mgmt/Systems/North%20Sutton%20Street/nssesxi04-mgmt?no_verify=1 wvm2 virt-v2v: libguestfs 1.28.1 (x86_64) [ 0.0] Opening the source -i libvirt -ic vpx://ARDA%5ccam@nssesxi-mgmt/Systems/North%20Sutton%20Street/nssesxi04-mgmt?no_verify=1 wvm2 input_libvirt_vcenter_https: source: scheme vpx server nssesxi-mgmt Enter ARDA\cam's password for nssesxi-mgmt: libvirt: ESX Driver error : internal error: Could not find compute resource specified in '/Systems/North Sutton Street/nssesxi04-mgmt' virt-v2v: error: internal error: invalid argument: cannot open libvirt connection 'vpx://ARDA%5ccam@nssesxi-mgmt /Systems/North%20Sutton%20Street/nssesxi04-mgmt?no_verify=1' If reporting bugs, run virt-v2v with debugging enabled and include the complete output: virt-v2v -v -x [...] # # virsh -c 'vpx://ARDA%5ccam@nssesxi-mgmt/Systems/North%20Sutton%20Street/nssesxi04-mgmt?no_verify=1' list --all Enter ARDA\cam's password for nssesxi-mgmt: error: failed to connect to the hypervisor error: internal error: Could not find compute resource specified in '/Systems/North Sutton Street/nssesxi04-mgmt' # I can access via http a list of VMs at the following URL: https://nssesxi-mgmt/folder?dcPath=North%2520Sutton%2520Street&dsName...
