I just installed Ubuntu Bionic (18.04.1) (Unity desktop) on both Oracle VirtualBox (VB - v5.2.18) and VMware Player (v14). I have Guest Additions on both VMs.
On VB, the %system is always about 20% (using $ sar) and all graphics interactions are super slow. Opening the Dash takes forever (~ 1min) and opening both LibreOffice Write and Calc take several minutes.
The same tasks on VMware Player are “fast” – a sec or two. I can actually see the animation when opening the Dash in Player, but not VB.
I have 3D acceration enabled on both. I’m using 8Gb Ram on both. I assigned 4 “CPUs”. My host is a Dell XPS i7.
Has anyone else been able to get Unity on VB to run ‘acceptably’ like it’s a real machine? It feels like something with the graphics emulation, but I can’t figure out what? (Xubuntnu runs acceptibly on VB, but not Unity.)
