In the wee small hours i decided to give #GnomeBoxes another chance as a possible alternative. Chose to install via #flatpak, coz my Host is 
#ArchLinux #KDEPlasma & i did not wish to risk possible gnome vs plasma file conflicts.
It did a fine job of installing an #ArchLinux VM [which i completed using the latest #ArchInstall v3.0.3], so then in an act of gross stupidity i ridiculously chose to see if it could handle a win10 VM via a 3-yr old ISO i have lying around. As i abandoned windoze "for real" in 2014, i had forgotten the many hours of time-wasting bullshit involved, at the end of which instead of getting something decent, you just get... windoze, ugh.
Anyway, so far it seems that GnomeBoxes is going ok, which makes a nice change as all prior tests of older versions failed to work properly. Doubt though atm that it'll persuade me to give up on #qemu / #kvm / #libvirt / #VirtManager. GB has no facility to Suspend VMs, so they need to be fully shutdown, which is a drag. Also, the FP version does not support USB transfer, which is a bugger, & so far i've not made #SharedFolders work [but think i know why].
