## KVM
|
|
|
|
This tutorial leverages KVM. So you need to have a linux machine on which KVM is installed.
|
|
|
|
You can find how to install KVM on any linux distribution on the Internet.
|
|
|
|
In this tutorial, [openSUSE Tumbleweed](https://en.opensuse.org/Portal:Tumbleweed) will be used, but in most cases, there should be no problem caused by specific distributions or libvirt versions.
|
|
|
|
Currently, I use the following packages:
|
|
|
|
```
|
|
# cat /etc/os-release
|
|
NAME="openSUSE Tumbleweed"
|
|
# VERSION="20190201"
|
|
ID="opensuse-tumbleweed"
|
|
ID_LIKE="opensuse suse"
|
|
VERSION_ID="20190201"
|
|
PRETTY_NAME="openSUSE Tumbleweed"
|
|
ANSI_COLOR="0;32"
|
|
CPE_NAME="cpe:/o:opensuse:tumbleweed:20190201"
|
|

## Running Commands in Parallel with tmux
|
|
|
|
[tmux](https://github.com/tmux/tmux/wiki) can be used to run commands on multiple compute instances at the same time. Labs in this tutorial may require running the same commands across multiple compute instances, in those cases consider using tmux and splitting a window into multiple panes with `synchronize-panes` enabled to speed up the provisioning process.
|
|
|
|
> The use of tmux is optional and not required to complete this tutorial.
|
|
|
|
|
|
|
|
If you want to setup tmux like above, `ctrl+b` -> `"` twice, then `ctrl+b` -> `alt+2`.
|
|
|
|
> Enable `synchronize-panes`: `ctrl+b` then `shift :`. Then type `set synchronize-panes on` at the prompt. To disable synchronization: `set synchronize-panes off`.
