VDI+BIOS Image and not linked base VM #3626

Hi

With the last GNS3 2.2 (on a LiveRaizo)

I tried to run a DEV VM of Win11 with QEMU

The win11 works. I don't see any problems.

But, if i disable the "Use as a linked base VM" in the template, the win11 doesn't boot : image

I manually run the node (not linked) and noticed errors like "Could not write to allocated cluster for streamOptimized".

When checking the disk format I also noticed it says streamOptimized. 

qemu-img info /home/gns3/GNS3/images/QEMU/WinDev2212Eval-disk1.vmdk

            cluster size: 65536
            format:

So I guessed the problem comes from the image being VMDK. I converted the base image to qcow2 using qemu-img convert -f vmdk -O qcow2 /home/gns3/GNS3/images/QEMU/WinDev2212Eval-disk1.vmdk /home/gns3/Downloads/WinDev2212Eval-disk1.qcow2 and imported the new image in the node and it booted correctly.

OK. But it's strange: I would have thought that the problem would have appeared with the particular method of starting a VM (snapshots: the linked VM) and not with the traditional method.
