how do I run a local widows of a program in a VM?

[ToddAndMargo]

Hi All,

Fedora 29
Xfce 4.13

I have a qemu-kvm virtual machine (VM) of Ubuntu.  I have
two programs that won't run in Fedora installed in it.

I know about "ssh -X11" and occasionally use it in other
situations.  But X11 is slow and clunky.

Is there a better way to run a local windows of a program
in a VM?

Many thanks,
