Moving a Windows 7 VM from VirtualBox to VMware Player
Published on 14th October 2012 Estimated Reading Time: 3 minutesSeeing how well Windows 8 was running in a VMware Player virtual machine and that was without installing VMware Tools in the guest operating system, I was reminded about how sluggish my Windows 7 VirtualBox VM had become. Therefore, I decided to try a migration of the VM from VirtualBox to VMware. My hope was this: it would be as easy as exporting to an OVA file (File > Export Appliance... in VirtualBox) and importing that into VMware (File > Open a VM in Player). However, even selecting OVF compatibility was insufficient for achieving this, and the size of the virtual disks meant that the export took a while to run as well. The solution was to create a new VM in VirtualBox from the OVA file and use the newly created VMDK files with VMware. That worked successfully to give me a speedier, more responsive Windows 7 VM for my pains.
Access to host directories needed reinstatement using a combination of the VMware Shared Folders feature and updating drive mappings in Windows 7 itself to use what appeared to it as network drives in the Shared Folders directory on the \\vmware-host domain. For that to work, VMware Tools needed to be installed in the guest OS (go to Virtual Machine > Install VMware Tools to make available a virtual CD from which the installation can be done) as I discovered when trying the same thing with my Windows 8 VM, where I dare not instate VMware Tools due to their causing trouble when I last attempted it.
Moving virtual machine software brought about its side effects, though. Software like Windows 7 detects that it's on different hardware, so reactivation can be needed. While Windows 7 reactivation was a painless online affair, it wasn't the same for Photoshop CS5. That meant that I needed help from Adobe's technical support people top get past the number of PC's for which the software already had been activated. In hindsight, deactivation should have been done before the move, but that's a lesson that I know well now. Technical support sorted my predicament politely and efficiently while reinforcing the aforementioned learning point. Moving virtual machine platform is very like moving from one PC to the next, and it hadn't clicked with me quite how real those virtual machines can be when it comes to software licensing.
Apart from that and figuring out how to do it, the move went smoothly. An upgrade to the graphics driver on the host system and getting Windows 7 to recheck the capabilities of the virtual machine even gained me a fuller Aero experience than I had before then. Full screen operation is quite reasonable too (the CTRL + ALT + ENTER activates and deactivates it) and photo editing now feels less boxed in too.
