ModEdit; related ticket: #18753: Linux Host: VMs on Virtualbox 6.0.x are running abnormaly slow on modern AMD Processors
Hi,
I'm experiencing an issue with my computer and virtualbox, suddenly I've discovered that my VMs run incredibly slow, both CPU and Graphically.
VMs boot slowly and take forever to do anything, in particular a debian 9 vm took me more than 1h to update via APT.
Previously the same VM on the same host computer was so fast I could even edit video using KDENLive inside the VM, however now it struggles even to move a window over the Mate desktop.
I've tried with Vitualbox 5.2.x and 6.0.x, all vga modes I've tried the test build VirtualBox-6.0.9-131597-Linux_amd64.run, always the same result, VMs are sluggish including a Windows XP one that alwas was super fast now it is so sluggish even the boot animation is slow.
I think this might have started after upgrading to kernel 5.0/5.1, this machine used to run VMs like a champ in Vbox before, thing is I have an intel computer running the same 5.1.15 kernel where virtualbox 6.0.8 performs great, so issue might be AMD specific.
This is /proc/cpuinfo:

Nothing else is slow on this computer, and it is rock solid stable (after disabling CPU C6 state that is).
Any help is welcomed.
