Setup Fedora virtual machine on VMWare

Table of Contents

Create a new VMWare Player Fedora VM

First we need to download Fedora ISO

Download Fedora netinstall ISO

Get the Fedora Netinstall Image (other resonably recent release should work as well, see Fedora Workstation Download page). This DVD image can be validated using a SHA256 hashing tool, for example on Unixy OSes by entering the following in a terminal:

echo "6554404b66d38b89693232966d9290ed62156e32d1edde4074b1d25c97a7b10e  Fedora-Workstation-netinst-x86_64-29-1.2.iso" | sha256sum -c
# (must return OK)

Replace sha256sum with shasum on OSX.

Create a new VM

In the VMWare Player GUI click "Create a New Virtual Machine" and choose the following parameters in the wizard:

  • Install operating system from ISO image

  • Type: Linux, Debian 9.x (64-bit)

  • Set machine name. We will use following name for this guide: gitianbuild_fedora

  • Maximum disk size: at least 40GB
  • We will store disk as single file in this guide, you can split it too
  • Click "Next"

Configure VM

To configure VM click on Customize Hardware

  • Memory Size: at least 3000MB, anything less and the build might not complete.

  • Increase the number of processors to the number of cores on your machine if you want builds to be faster.

  • Check settings once again and click Finish

Note: Marking checkbox `Automatically power on this virtual machine after creation will start the VM after clicking finish and closing next window:

Installing Fedora

This section will explain how to install Fedora on the newly created VM.

  • Choose the default option. This will start the graphical installer.

  • Pick the language, locale and keyboard settings of your choice. You can just go with the defaults or select your own information.

  • The VM will detect network settings using DHCP, this should all proceed automatically

  • Afterward, the installer will automatically pick an appropriate Installation Source (closest mirror) and starts fetching the package metadata.

  • Then, click the button for Software Selection and choose the Minimal Install from as the base environment and no addons for the selected environment. This will reduce installation time and disk usage.

  • Finally, open the settings for Installation Destination and click Done. The default settings are just fine.

  • The Installation Summary should look like this:

  • Confirm by clicking on Begin Installation.
  • You can leave the root password empty. Otherwise, enter it twice and remember it for later.
  • Also, create a new user. Name the new user gitianuser (the full name doesn't matter, you can leave it empty)
  • Select Make this user administrator to add them to the wheel group.
  • Choose a user password and enter it twice (remember it for later)

  • Complete the installation by clicking Finish configuration. Then wait for it to complete and select Reboot.
  • If the greeter asks you to install fedora, make sure to remove the ISO: In the running VirtualBox instance, select Devices > Optical Drives > Remove disk from virtual drive. Then reboot again.
  • After reboot you will have a working Fedora VM. Congratulations!

You'll be presented with a screen similar to this.

Connecting to the VM

After the VM has booted you can connect to it using SSH, and files can be copied from and to the VM using a SFTP utility.

  1. Find out your IP address: Login to your VM and run ifconfig to find IP address of your vmware network adapter: 
    ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
     inet 172.16.123.143  netmask 255.255.255.0  broadcast 172.16.123.255
     inet6 fe80::20c:29ff:fe7c:a908  prefixlen 64  scopeid 0x20<link>
     ether 00:0c:29:7c:a9:08  txqueuelen 1000  (Ethernet)
     RX packets 62147  bytes 79269431 (79.2 MB)
     RX errors 0  dropped 0  overruns 0  frame 0
     TX packets 17692  bytes 25055408 (25.0 MB)
     TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
  2. On your machine edit or create ~/.ssh/config and add: 
    host gitian-fedora
    HostName 172.16.123.143
    Port 22
    PreferredAuthentications password
    User gitianuser
  3. Connect to gitian-fedora. On Windows you can use putty and WinSCP.

For example, to connect as gitianuser from a Linux command prompt use

  $ ssh gitian
  The authenticity of host '[gitian-fedora]:22 ([127.0.0.1]:22)' can't be established.
  RSA key fingerprint is ae:f5:c8:9f:17:c6:c7:1b:c2:1b:12:31:1d:bb:d0:c7.
  Are you sure you want to continue connecting (yes/no)? yes
  Warning: Permanently added '[gitian-fedora]:22' (RSA) to the list of known hosts.
  gitianuser@gitian's password: (enter gitianuser password configured during install)

Optional - Easier login to the VM with public key

For easier login with public key you'll need to generate an SSH key, e.g. by following the instructions under "Generating a new SSH key".

After that, login to the VM and enter:

mkdir .ssh

On your machine edit or create ~/.ssh/config and add:

host gitian-fedora
    HostName 172.16.123.143
    Port 22
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa
    User gitianuser

Open a new terminal tab and enter:

scp ~/.ssh/id_rsa.pub gitian-fedora:.ssh/authorized_keys

Next time you need to login to the VM, just use: ssh gitian
