Yes, precicely this is what I am trying to do. The URL (deviceUrl) is obtained once the call to ImportVApp is successful, it does not import the disk on root directory but to the new VM directory created after the importvapp call. I remember trying this on ESXi4.1 and it used to work fine, ESXi5 seems to block it. I am logged in with "root" credentials.

OVA disk can be compressed (compression algorithm is identified as one of the fields inside creaimportspec result varible), also as OVA optimizes the disk we need to use this URL to upload the valid content and rest necessary messaging is done by server itself (say deflate the disk, uncompress it etc.).
