Intro¶
This is taggart’s process for generating lightweight debian VM images that use serial console and libvirt to run them.
Setup vmdb2 yaml file:¶
steps:
- mkimg: "{{ output }}"
size: 2G
- mklabel: msdos
device: "{{ output }}"
- mkpart: primary
device: "{{ output }}"
start: 0%
end: 100%
tag: root
- kpartx: "{{ output }}"
- mkfs: ext4
partition: root
- mount: root
- debootstrap: sid
mirror: http://mirror:9999/debian
target: root
- apt: install
packages:
- linux-image-amd64
tag: root
- grub: bios
tag: root
console: serial
- chroot: root
shell: |
echo "root:test" |chpasswd root
Create VM image¶
# vmdb2 test.vmdb --output test.img --verbose
Create VM¶
# virt-install --connect qemu:///system --virt-type kvm --name test --vcpus 2 --memory 1024 --disk size=10,path=/srv/kvm/test.img,format=raw --import --network bridge=br0 --os-type linux --os-variant debiantesting --noautoconsole
Utility commands¶
- connect to console:
# virsh console test
- get rid of VM so you can recreate it:
# virsh destroy test;virsh undefine test
