#18753 fixed Linux Host: VMs on Virtualbox 6.0.x are running abnormaly slow on modern AMD Processors JPFSanders
Description

For some reason VirtualBox 6.0.x has suddenly become very, very slow running on modern AMD hardware and Linux.

Any VM Guest being it Linux or Windows has become completely inpracticable.

In my case I run on a "AMD Ryzen 7 1800X Eight-Core Processor" and VirtualBox struggles to run anything.

I'm not sure when this might have started as in the same computer I remember VirtualBox 5.2 being blazingly fast.

KVM in the same hardware flies in comparison.

I've tried to disable Audio, 3D acceleration, change VGA, remove USB, etc, nothing makes a big difference.

I've tried VMs running Windows XP, Windows 8.1, CentOS 7.x, Debian 9, Ubuntu 16.04, 18.04... They are all unusable.

Attached the vmlog for my Debian 9 test vm

Also below there are the links to forum entries where I have done more troubleshooting, and another forum entry where someone details having performance problems too with an AMD Threadripper CPU.

Please, let me know if I can provide with any more information.

#18745 fixed Vbox 6.0.8 keeps keyboard grab even after mouse is out -> fixed in openSUSE Luiz Angelo Daros de Luca
Description

Hello,

I use OpenSUSE Tumbleweed with frequent updates (Linux kernel 5.1.15-1-default). Since last two releases, vbox mouse integration is not working as expected.

When I have mouse integration enabled, I expected that VM looses keyboard grab as soon as mouse cursor is out. However, vbox captures it back.

Steps to reproduce:

  1. Start a VM (tested with win7 or win10). Additions are installed but it happens even during boot.
  2. Opened an editor in my host machine (OpenSUSE Tumbleweed)
  3. Put VM and editor window side by side
  4. Click inside the VM to let it grab keyboard
  5. Click inside the editor to leave VM. At this point, I can type one or two characters before vbox grab keyboard back.

The only way to make vbox leave keyboard alone is using "host key" (in my case, left super (win)).

I'm using vbox RDP as a workaround while this is happening.

Machine is also eventually crashing, freezing VM window without any entry in Vbox.log.
