Hi Matthias,
Thanks for the response. For connecting to ESXi, I couldn't find any environment setting to make 'curl' point to the client certificates. So, for the time being, I hard-coded the location in libvirt-<version>/src/esx/esx_vi.c.
esx_vi.c: curl_easy_setopt(curl->handle, CURLOPT_SSLCERT, "/etc/pki/libvirt/clientcert.pem");
esx_vi.c: curl_easy_setopt(curl->handle, CURLOPT_SSLKEY, "/etc/pki/libvirt/private/clientkey.pem");
esx_vi.c: curl_easy_setopt(curl->handle, CURLOPT_CAINFO, "/etc/pki/CA/cacert.pem");
This has worked for me. Perhaps there's a cleaner way of doing this? If I find something, I'll share w/ everybody on the list.
regards,
Shiva

What you basically have to do is create your own Certificate Authority
(CA) and then issue a new server certificate with that CA as described
in the guide you mentioned. Then transfer this server certificate to
the ESX server and put it into the correct place. I think you already
have done this correctly
The last thing that's missing (the same as in the mailing list thread
I linked above) is that you need to configure your client properly.
The SSL infrastructure on your client needs to know about your custom
CA. libcurl has to be able to find and use it in order to verify that
the certificate your ESXi server present is valid. How this has to be
done depends on the SSL backend libcurl is using and on your distro.
