Running a KVM image within VirtualBox
- Get your kvm virtualmachine zipfile
- Extract the zip, you should get a .qcow2 file
Use qemu to convert this to a vdi file: qemu-img convert -O vdi virtual.qcow2 virtual.vdi
Create a new vm within VirtualBox, and select the converted .vdi file as its harddisk
- Profit
For raw files: VBoxManage convertdd virtual.raw virtual.vdi --format VDI
