Thanks a ton for the reply Matthias. I tried your suggestion but now I got one more message saying:

virsh # connect esx://172.16.73.14/?no_verify=1
Enter username for 172.16.73.14 [root]: root
Enter root's password for 172.16.73.14
error: Failed to connect to the hypervisor
error: internal error: curl_easy_perform() returned an error: Unsupported protocol (1) : Protocol https not supported or disabled in libcurl

Is it because of the curl package? I thought of building curl with https support but there was no such option (--with-https). Can you please tell me why am I getting this. 

Regards,
Varun

See http://libvirt.org/drvesx.html#certificates

By default an ESX server uses self-signed SSL certificates. You either
need to tell libvirt to not verify the certificates (virsh connect
esx://172.16.73.14/?no_verify=1) or replace the SSL certificates with
offically signed ones.
