virtdc : virtual machine management CLI

virtdc A high-level Python CLI for virtual machine placement and scaling which provides a way to create, manage and monitor virtual machines effectively.

Pre-requisite

libvirt api is a required pre requisite for this package Use yum or apt-get:

$ sudo yum install libvirt

Setup

Use easy_install or pip:

$ sudo mkdir /var/lib/virtdc
$ sudo pip install -t /var/lib/virtdc virtdc
$ sudo cp /var/lib/virtdc/usr_bin/virtdc.py /usr/bin/virtdc

Commands

The following are the core functionalities of the virtdc api

create - creates new domain from the base image:

$virtdc create -h
usage: virtdc create [-h] vmid cpu memory maxmemory io

positional arguments:
  vmid        get the vmid
  cpu         get the cpu
  memory      get memory in KiB
  maxmemory   get maximum memory in KiB
  io          get the io in KiB

terminate-terminates the running domain:

$virtdc terminate -h
usage: virtdc terminate [-h] vmid

positional arguments:
  vmid        get the vmid

list-lists running domain in all hosts:

$virtdc list -h
usage: virtdc list [-h]

dominfo gives the domain information:

$virtdc dominfo -h
usage: virtdc dominfo [-h] vmid

positional arguments:
  vmid        get the domain id

hostinfo gives the host information:

$virtdc hostinfo -h
usage: virtdc hostinfo [-h] hostname

positional arguments:
  hostname    get the host

force-migrate migrates domain from source host to dest host:

$virtdc force-migrate -h
usage: virtdc force-migrate [-h] vmid sourcehost desthost

positional arguments:
  vmid        get the domain
  sourcehost  get the source host
  desthost    get the dest host

removehost-removes the host from the cluster:

$virtdc removehost -h
usage: virtdc removehost [-h] hostname

positional arguments:
  hostname    get the host

addhost-adds new host to the cluster:

$virtdc addhost  -h
usage: virtdc addhost [-h] hostname cpu memory io

positional arguments:
  hostname    get the host
  cpu         get the cpu
  memory      get memory in KiB
  io          get the io in KiB

getip-gets domain ip:

$virtdc getip  -h
usage: virtdc getip [-h] vmid

positional arguments:
  vmid        get the domain id

monitorgraph-monitors cpu, memory, io usage:

$virtdc monitorgraph  -h
usage: virtdc monitorgraph [-h]
