Has anyone had luck getting decent GUI performance (macOS host, Linux guest)? I don't need 3D, just sane 2D performance.<p>The last time I tried this, it was so bad that I had to drastically decrease the window size to get reasonable performance. As in, it would basically lock up above a certain window size, and no reasonable amount of waiting would get it to respond. (And yes, I fiddled with all of the obvious knobs for CPU/memory/graphics/etc.) I figure in this day and age of AWS and the like, we should have very, very good open source virtualization software, but no amount of fiddling seems to get it to work well for me.
