HTTP error code 417 is related to the Expect header. The error
indicates that the server or a proxy in between doesn't handle the
Expect header. I assume that the ESXi sever itself is not the problem,
because it works for me here. Maybe there is a HTTP proxy between your
computer and the ESXi server that returns this 417 error code.

This problem is probably related to libvirt sending a dummy Expect
header instead of sending no Expect at all.

If you're building libvirt from source you can try this patch that I
just send to the mailing list for review

https://www.redhat.com/archives/libvir-list/2012-February/msg00860.html

It fixes the Expect header problem and might fix your connection problem.
