Installing virtual machines with virt-builder
=============================================

Main reference: http://libguestfs.org/virt-builder.1.html. The man page
of `virt-builder` has ton of details.

Fedora
------

Raw
~~~

Prepare a Fedora 28 guest with Raw format:

    $ virt-builder fedora-28

To import the above image into libvirt:

    $ virt-install --name f28vm --ram 2048 \
        --disk path=./fedora-28.img,format=raw \
        --nographics --import --os-variant fedora27

QCOW2
~~~~~

Create a Fedora 21 guest:

    $ virt-builder fedora-28 -o f28vm --format qcow2 --size 10G

    [OR]

Prepare Fedora 21 and update to latest available packages:

    $ virt-builder fedora-28 -o f28vm --format qcow2 \
        --update --selinux-relabel --size 30G

    [OR]

To create a Fedora Rawhide VM, by specifying a root password:

    $ virt-builder fedora-28 -o rawhide.qcow2 \
        --format qcow2 \
        --root-password password:123456 \
        --update --selinux-relabel --size 40G\
        --install "fedora-repos-rawhide yum-utils"
      

Import the any of the above QCOW2 guest to get access to a serial
console:

    $ virt-install --name f28vm --ram 2048 \
        --disk path=/home/kashyap/fedora-28.qcow2,format=qcow2 \
        --nographics --import --os-variant fedora27

[Use libvirt's `virsh` to manipulate your virtual machines.]


Debian
------

By default, Fedora has serial console enabled, to create a Debian guest
and have it a enable virtual console (for debugging later):

    $ virt-builder debian-7 \
      --edit '/etc/inittab: s,^#([1-9].*respawn.*/sbin/getty.*),$1,'
