vmware sanal makine diskini, virtualbox sanal makine diskine çevirmek

Bu gün firemon programını test edeyim dedim.
Gelin görünkü demo yu vmware sanal makinesi olarak yapmışlar..
Eeeee şimdi vmware mi kuracam dedim ve vmware makinesini nasıl vbox çevrilir araştırayım dedim.
Gördüm ki çok basitmiş...

1. qemu-img convert firemon-5.2.1.53.vmdk -O raw firemon-5.2.1.53.bin

2. vboxmanage convertfromraw firemon-5.2.1.53.bin firemon-5.2.1.53.vdi
Converting from raw image file="firemon-5.2.1.53.bin" to file="firemon-5.2.1.53.vdi"...
Creating dynamic image with size 64424509440 bytes (61440MB)...

Hepsi bu kadar. Artık virtualboxta bir sanal sunucu oluşturup, diski tanıttım ve demo başladı...
