How do I install QEMU 3.0 on Ubuntu 18.04?

  • 772

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/
./configure
make

    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
