Adventures & experiences in contemporary technology
Recently, VirtualBox gained fuller support for Windows 11 and I successively set up a new Windows 11 virtual machine that I hope will supplant a Windows 10 counterpart in time. The setup itself was streamlined but I ran into such stability issues that I set the new VM aside until a new version of VirtualBox got released. That has happened with the appearance of version 7.0.2 but Windows 11 remains prone to freezing on my Linux Mint machine. Thankfully, that now is much less frequent but the need for added stability remains outstanding.
While I was thinking about trying our Virtualbox 7.0.0, I remembered a QEMU machine that I had running Windows 11. Though QEMU proved more limited than VirtualBox when it came to having easy availability of functionality like moving data in and out of the virtual machine or support for sound, there was no problem with TPM support or system stability. Since it did contain some useful data, I wondered about converting its virtual hard disk to VirtualBox format and it is easy to do. First, you need to install qemu-img and other utilities as follows:
sudo apt-get install qemu-utils
With that in place, executing a command like the following performs the required conversion. Here, the -O switch specifies the required file type of vdi in this case.
qemu-img convert -O vdi [virtual hard disk].qcow2 [virtual hard disk].vdi
While I have yet to mount it on the new Virtualbox Windows 11 virtual machine, it is good to have the old virtual hard disk available for doing so. The thought of using it as a boot drive in VirtualBox did enter my mind but the required change of drivers and other incompatibilities dissuaded me from doing so.
