Title sounds confusing and It might be wrong terminology, sorry about that.
I have POP OS and windows in VM (virtualbox) for few apps that are not available on linux. Im trying to install one app that requires diferent activation method because it recognized Im running virtual machine. Is there any way to hide that so I can activate the app the way I usually do on non-VM windows?
With vbox I don't think you can do that, nor with any other hypervisor delivering full virtualization. You could try with a paravirtualization, like Xen, and see if you can trick the OS
Note that I don't know if windows is supported as a paravirtualized guest.
Was about to post this. Running qemu command line can do this, unfortunately I don't have my old scripts to do it. It's pretty common when doing GPU passthrough, so maybe look there?
It might be possible to trick the app's activation function. But before you can do that, you'd have to understand how it is checking for virtualization, so that you know what aspect of the VM's behavior to tweak.
Someone on Lemmy might be able to help you with that, if they knew what app you were trying to use...
