Hi All,

I am struggling with the resolution of my guest machines, I cannot change it from 800x600. I have read through the forums and tried all the suggestions and am having no luck

I am running Windows 10 on host and Windows XP on Guest. My version of VirualBox is the latest 5.0.0. I have installed the guest additions but I cannot get the resolution to change. Please help! I am struggling to finish my work on a miniature 800x600 window.

Cheers

Please post a VM log file. With the VM fully shut down, right click and "Show Log" in the GUI, save "VBox.log" (ONLY) to a zip, and attach the zip here.

Log file attached.

I appreciate the help

Cheers

VirtualBox VM 4.2.32 r101581 win.amd64 (Jul 9 2015 16:20:11) release log

While you can run an older guest addition then the version of VirtualBox installed, it is not suggested to do the reverse. The new additions will be looking for code that does not exist yet. I would remove the ones you have and install the proper one or update you version of VirtualBox.

I would also increase the graphics RAM - 27MB seems a bit low. I would double that.

I would also increase the guests RAM allocation from 512MB to 2048MB, since the host can easily afford it.

Finally, bear in mind that Win10 is not yet a supported host.
