Sample Queries and corresponding outputs

1) To initialize the service.

• Checks for the number of running VMs, populates MAC list and also assigns VLAN ids.
• Is also supposed to send the VLAN information to the server on ASN-GW

  wget http://wm-asngw-02:5012/wimaxvm/initvms
  
  
  vm30 VLANid  7         mac address='52:52:52:52:52:52'/
  vm7 VLANid  2         mac address='52:54:00:1c:00:cb'/
  vm10 VLANid  6         mac address='54:52:00:2c:05:7a'/
  vm55 VLANid  3         mac address='01:23:45:67:89:ab'/
  vm57 VLANid  4         mac address='01:32:54:67:98:ba'/
  vm58 VLANid  5         mac address='01:65:23:67:98:ba'/
  vm5 VLANid  0         mac address='52:54:00:2a:85:b6'/
  vm6 VLANid  1         mac address='52:54:00:34:aa:a3'/
  

2) Start VM

• Start vm, assign vlan tag and send info to server on ASNGW
• Socket part is yet to be integrated

   http://wm-asngw-02:5012/wimaxvm/start/?vmname=vm30
  Domain vm30 started  with vlan tag 9
  

3) Stop VM

• Similar to start VM, but does exactly the opposite

   http://wm-asngw-02:5012/wimaxvm/stop/?vmname=vm8
  Domain vm8 destroyed
  

4) Get statistics about a VM

• Gets all relavent information for a particular VM name

  http://wm-asngw-02:5012/wimaxvm/vmstat/?vmname=vm8
  <domain type='kvm' id='40'>
    <name>vm30</name>

        <source network='default'/>

      <graphics type='vnc' port='5905' autoport='yes' listen='127.0.0.1'/>
    </devices>
  </domain>
  

5) Get VM list

• Useful for an admin and gives a list of all VMs.
• Format is vmname, Vlanid, vm-mac-addr.

   http://wm-asngw-02:5012/wimaxvm/vmlist
  
  vm30 VLANid  7         mac address='52:52:52:52:52:52'/
  vm7 VLANid  2         mac address='52:54:00:1c:00:cb'/
  vm10 VLANid  6         mac address='54:52:00:2c:05:7a'/
  vm55 VLANid  3         mac address='01:23:45:67:89:ab'/
  vm57 VLANid  4         mac address='01:32:54:67:98:ba'/
  vm58 VLANid  5         mac address='01:65:23:67:98:ba'/
  vm5 VLANid  0         mac address='52:54:00:2a:85:b6'/
  vm6 VLANid  1         mac address='52:54:00:34:aa:a3'/
