Hi Everyone,
 
Merry Christmas and Happy New Year!
 
I'm trying to upload disk to ESX 5.0 server using the URL obtained by the server (during VM installation process); I'm using libcurl support in libvirt to upload the disk, but I get this error on file upload:
----------------------
* About to connect() to <ip> port 443 (#1)
*   Trying <ip>... * connected
* found 153 certificates in /etc/ssl/certs/ca-certificates.crt
*        server certificate verification SKIPPED

----------------------

To achieve this operation I've added a routine to support file Upload (for ESX driver as currently it only support buffer upload), I verified its functioning my uploading a file using datastore based URL:
(http(s)//<ip>/file??dcPath=ha-datacenter?dsName=xxx).
 
CURL options provided by me are;
 
-----------
   curl_easy_setopt(curl->handle, CURLOPT_UPLOAD, 1L);
    curl_easy_setopt(curl->handle, CURLOPT_URL, url);
    curl_easy_setopt(curl->handle, CURLOPT_READDATA, <data pointer>);
    curl_easy_setopt(curl->handle, CURLOPT_INFILESIZE_LARGE,
                        (curl_off_t) fileData->size);
    curl_easy_setopt(curl->handle, CURLOPT_READFUNCTION,
                        <read function>);
    curl_easy_setopt(curl->handle, CURLOPT_VERBOSE, 1);
------------------------
 
My understanding is there needs to be some tuning done to ESX server to accept this upload operation, please suggest if anyone has faced this issue before.
 
Thanks!
