Contributing

• Fork the project

• Start a feature/bugfix branch

• Commit and push until you are happy with your contribution

• Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.

• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.

Examples

Connectivity Options

uri = "qemu:///system"              # libvirt running locally
uri = "qemu:/fqdn//system"          # used for QEMU+TLS connection
uri = "qemu+ssh:/user@fqdn//system" # used for SSH connection
uri = "qemu+tcp:/fqdn//system"      # used for non secured tcp connection

Establish the connection

conn = Virt.connect(uri)

get the hypervisor

host = conn.host

get the list of running guests

host.running_guests

get the list of stopped guests

host.defined_guests

or a simple hash of both

host.guests

create a new guest

guest=Virt::Guest.new({:name => "test123"})
guest.vcpu = 2
guest.volume.size = 10 # in GB

guest.save
guest.start

puts guest.mac

guest.shutdown     # initiate a shutdown
guest.poweroff     # forces a shutdown

Many more options exists, make sure checkout the api/tests

list of host bridges

host.interfaces # physical interfaces
host.networks   # virtual / NAT interfaces

Storage

host.storage_pools

host.volumes
