Returns a Pangea::Host object

There’s no direct mapping to xen-api

# File lib/pangea/objects.rb, line 198
    def self.connect(url, username, password)
      @link = Link.new(url, username, password)
      @link.connect
      @ref = @link.client.call('host.get_all', @link.sid)['Value'][0]
      Host.new(@link, @ref)
    end

        puts e.message
        return false
      end
      true
    end

Returns an Array of Pangea::HostCpu objects

xen-api: host.get_host_cpus

# File lib/pangea/objects.rb, line 120
    def cpus
      list = []
      ref_call(:get_host_CPUs).each do |hcpu|
        list << HostCpu.new(@link, hcpu)

# File lib/pangea/objects.rb, line 175
    def networks
      nets = [] 
      p = @link.client.proxy( 'network' )
      p.get_all(@link.sid)['Value'].each do |ref|
        nets << Network.new(@link, ref)
      end
      nets
    end

      @link.connect
      @ref = @link.client.call('host.get_all', @link.sid)['Value'][0]
    end

resident_vms() click to toggle source

Get the list of resident virtual machines controlled by the hypervisor.

Returns an Array of Pangea::VM objects

xen-api: host.get_resident_VMs

# File lib/pangea/objects.rb, line 104
    def resident_vms
      vms = []
      ref_call(:get_resident_VMs).each do |vm|

      end
      vms
    end
