I am using a Ryzen processor and, as such, I have been told that I need to use QEMU 3.0 for the SMT patch.

The issue is that I cannot seem to find any way to install it on Ubuntu 18.04 LTS at all. It's not in the repositories, obviously; but, there are also no other PPAs or anything similar.

It seems that we need to compile QEMU 3.0.0 manually.

At first we remove version installed from official repository (if any):

sudo apt-get purge "qemu*"
sudo apt-get autoremove

We should start by installing its build-dependencies - at first enable Source Code repositories in Software and Updates (software-properties-gtk) and then:

sudo apt-get build-dep qemu

Then download it, configure and compile:

cd ~/Downloads
wget https://download.qemu.org/qemu-3.0.0.tar.xz
tar -xf qemu-3.0.0.tar.xz
cd qemu-3.0.0/

and then use checkinstall:

sudo apt-get install checkinstall
sudo checkinstall make install
sudo apt-get install ./*.deb

if you want to remove it - remove its packages as usual.

And as the result you will have QEMU 3.0.0 installed

$ qemu-system-x86_64 --version
QEMU emulator version 3.0.0

    I ended up doing this but you should probably mention that on ubuntu you should use checkinstall instead of make install, because that packages it as a .deb and adds it to the package manager Aug 22, 2018 at 20:17

    You are completely right about checkinstall. New contributor badge forced me to lower my knowledge and skills ;)

    In some shells sudo apt-get purge "qemu*" should be used with the quotes, or related packages will not be removed.
