OpenNebula

Hello, I did som eupdates in aplpine context scripts to support loadbalanacing, email notifications etc.. and I like to see it integrated in OpenNebula.

1. Virtual Router - Add support by adding checkbox for set interface as gateway
   • ETHx_VROUTER_GATEWAY
2. Virtual Router - Add support by adding email notifications fields
   • VROUTER_KEEPALIVED_NOTIFY_EMAIL
   • VROUTER_KEEPALIVED_FROM_EMAIL
3. Virtual Router - Add support for configure sync interface and also not allocate addresses if sync is on other interface, but just VIP
   • ETHx_VROUTER_KEEPALIVED_INF
4. Virtual Router - Add support for define Load Ballancers
   • VROUTER_LBx_ALGO
   • VROUTER_LBx_DELAY_LOOP
   • VROUTER_LBx_DEV
   • VROUTER_LBx_KIND
   • VROUTER_LBx_PORT
   • VROUTER_LBx_PROTOCOL
   • VROUTER_LBx_SERVERy_IP
   • VROUTER_LBx_SERVERy_PORT
   • VROUTER_LBx_SERVERy_WEIGHT
   • VROUTER_LBx_SERVERy_CHECKz_TYPE
   • VROUTER_LBx_SERVERy_CHECKz_PORT
   • VROUTER_LBx_SERVERy_CHECKz_TIMEOUT
5. Services - Add support for virtual routers / load ballancers
   • also add support by some context var to real servers with direct routing LB mode, so can be updated context scripts which add arp filtering and VIP to interface.
6. Virtual Routers - remove keepalived_id - no need this, we can relay on vrouter_id. VRRP communication is based on VIP and ID have effect only if multiple instances are running on same NIC
7. Virtual Routers - keepalived_password should be auto generated
