You need spice-vdagent

You need spice-vdagent

Debian or Kali Linux installed to as KVM (libvirtd) guests do not automatically have qemu-guest-agent or spice-vdagent installed. This will prevent seamless movement of the mouse cursor between the guest and host desktop in Virtual Machine Manager (requiring the use of a Ctrl-Alt to release the cursor from the guest window).

To cure this, install both qemu-guest-agent and spice-vdagent on each guest and reboot (the guests).

$ sudo apt install qemu-guest-agent
$ sudo apt install spice-vdagent

Fix Ubuntu and other Linux slow/hanging file copying via USB.

If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes

I suggest you edit your /etc/rc.local file to make this change persistant across reboots.

sudo nano /etc/rc.local

CPU isolation bash script for KVM QEMU VFIO gpu passthrough for virtual machine performance optimizations using libvirt-hooks and cgroups
#!/bin/bash
# Cores reserved for the host machine
# Must include QEMU IO/Emulation cores if configured
# Ex: 1st Core -> reserved=0
# Ex: 1st & 2nt Cores -> reserved=0,1
# Ex: 1st Physical Core (16 Virtual Cores) -> reserved=0,8
reserved=0,8
# Host core range numbered from 0 to core count - 1

True Colour (16 million colours) support in various terminal applications and terminals

Terminal Colors

There exists common confusion about terminal colors. This is what we have right now:

  • Plain ASCII
  • ANSI escape codes: 16 color codes with bold/italic and background
  • 256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
  • 24-bit true color: "888" colors (aka 16 milion)
