@deadbeefdotmonster Last time [not recently, maybe a year'ish ago] that i tried enabling 3D Accel [is that what you mean by "hardware accel"?] it seemed to work well, but it broke the ability for me to Suspend [aka Save] my VMs each time, ie, i had to fully SD them, then cold SU them next time. That was a bigger PITA for me than the hitherto lack of accel, so i disabled it again ever since. Ofc #QEMU / #KVM / #libvirt / #VirtManager have had many updates since then. Maybe it's better now?
