Hello All,

I have just started studying the libvirt and I am trying to connect to ESX Server (version 4) using virsh (version 0.7.5) using the following command:

libvirt/virsh 0.7.5 is quite old, if possible you should use a more recent release. But this is just a recommendation, libvirt 0.7.5 will work with ESX.

virsh -c esx+ssh://root@<fully qualified hostname)>

It inquires the root password and as soon as I inform the password it throws the error:

error: cannot recv data: Connection reset by peer error: failed to connect to the hypervisor

As stated here http://libvirt.org/drvesx.html#uri the ESX driver does not utilize the normal libvirt transport mechanism such as SSH. Therefore esx+ssh:// doesn't work. The ESX driver uses the HTTP(S) based vSphere API of the ESX server. The correct virsh call looks like this virsh -c esx://root@<fully qualified hostname> If you did not replace the default self-signed SSL certificate on the ESX server with you own certificate then this call will fail with a certificate verification error. You can tell the ESX driver to not verify the SSL certificate using virsh -c esx://root@<fully qualified hostname>/?no_verify=1

I can access my server using ssh. I am running it from Ubuntu 10.04 and the libvirt version 0.7.5. Can someone help me?

Do you used the Ubuntu provided libvirt package? That won't work, because Ubuntu/Debian ship libvirt packages without ESX support. In that case you'll need to build libvirt from source to get ESX support. -- Matthias Bolte http://photron.blogspot.com
