400 means bad request. You probably have a character in you password
that needs to be escaped in XML: <, >, &, ', "

libvirt currently doesn't escape the password properly when building
the SOAP request. You can manually workaround this by entering the
password in escaped form. For example when your password is some&word
enter some&word instead.

I posted a patch to fix this:

By default libvirt uses HTTPS to talk to vSphere server. You can
disable TLS by using the transport=http query parameter like this

virsh -c "vpx://root@10.51.4.11/dc1/dc1-cluster-e01/dc1-vsphere-e04/?no_verify=1&transport=http"

But you'll have to configure the vCenter server to accept HTTP
connections if you want use this.
