Freshly Brewed Virtualsquare

Dynamically create a disk image to test the latest developments of Debian sid and virtualsquare

The script brew_v2 downloads the latest version of SID/unstable from the Debian Official Cloud Images and customizes it to be used as a Tutorial environment for the Virtualsquare projects.

Requirements

brew_v2 should need the following packages:

$ apt-get install qemu-kvm qemu-utils parted libguestfs-tools

Usage

Simply run brew_v2:

$ ./brew_v2

At the end the script creates a disk image file like:

debian-sid-v2-amd64-daily-20200526-275.qcow2

(20200526 is the date and 275 is the version number of the latest version so it will be updated consistently)

This image can be used to start a kvm virtual machine. e.g.:

$ kvm -smp 8 -drive file=debian-sid-v2-amd64-daily-20200526-275.qcow2 -m 1G \
    -monitor stdio -netdev type=user,id=net,hostfwd=tcp::2222-:22 \
    -device virtio-net-pci,netdev=net

When the VM has booted log in as root (password virtualsquare) and run the following command:

# ./get_v2all

This command installs all the packets needed by the virtualsquare projects and then downloads, builds and installs all the altest versions of the projects directly from the development repositories.

Log in and try your experiments

Virtualsquare tools do not generally require root access. So an unprivileged user named user (password virtualsquare) has been added for the tests.

It is possible to log-in on the console or by ssh (a tunnel is provided as localhost at port 2222):

$ ssh -p2222 -X user@localhost

This example provides also a X-window forwarding service.

In case you update the disk image (e.g. using brew_v2 again) ssh can complain that the host key has changed. In case delete the previous key:

$  ssh-keygen -R "[localhost]:2222"
