Convert Citrix XVA file into something I can use in VMWare

Hello,

I have a few XVA files exported from Citrix XEN server that I need to get running on a VMWare infrastructure.

How can I convert these XVA files into something that VMWare can use?  I cannot go back to the XEN environment and re-export or connect a VMWare stand-alone-converter to any of the running VM's, although I would have preferred to pull them in while they were running using the Stand Alone Converter Agent this way.

I have XVA files already on an external disk that I need to get into VMWare.  I'd like not to have to install a XEN server to do this, but I have read that it may be possible to run a XEN server nested inside of a VMWare server.  Is there a more direct way?  I have VSphere at my disposal, lots of storage, the Stand Alone Converter, and I've downloaded XenConverter, but it seems that this wants to pull a running server into XEN, not the other way around.

help is appreciated, thanks!
