As the ESX driver documentation says, you need to use
virConnectOpenAuth (what virsh does by default). You're error message
talks about virConnectOpen so there is your problem. You need to use
virConnectOpenAuth with the Ruby Bindings too.

Until libvirt 0.9.2 the ESX driver declines connection attempts when
virConnectOpen is used. Since 0.9.2 this is reported as the error it
actually is.

When the ESX driver declines the connection attempt libvirt will end
up trying to connect to a non-existing libvirtd on the ESX server in
order to find a driver that accepts the connection attempt. By default
it uses TLS for this and that's why it's looking for TLS certificates.
This is not related to the no_verify option.

So you're probably using libvirt < 0.9.2 and are using virConnectOpen
instead of virConnectOpenAuth.
