Isntall ubuntu 16 or something friendly with GUI on the virtual machine.
Download https://github.com/iridiumdev/iridium-qt-wallet/releases/download/v1.0.0/Iridium-qt
then in the terminal
GUI wallet will be launched and synchronized.
Then you can send your wallet files  created by windows to your ubuntu machine.
And then in the Qt wallet, File -> open wallet. It will show your balance.

Wallet just generates valid address and keys for it. So you can do all that stuff later. Or when windows qt will be ready.
