Initial patch for VXLAN support.
Fully functional, hopefully, for GuestNetwork - AdvancedZone.
Patch Note:
in cloudstack-server
- Add isolation method VXLAN
- Add VxlanGuestNetworkGuru as plugin for VXLAN isolation
- Modify NetworkServiceImpl to handle extended vNet range for VXLAN isolation
- Add VXLAN isolation option in zoneWizard UI
in cloudstack-agent (kvm)
- Add modifyvxlan.sh script that handle bridge/vxlan interface manipulation script
-- Usage is exactly same to modifyvlan.sh
- BridgeVifDriver will call modifyvxlan.sh instead of modifyvlan.sh when VXLAN is used for isolation
Database changes:
- No change in database structure.
- VXLAN isolation uses same tables that VLAN uses to store vNet allocation status.
Known Issue and/or TODO:
- Some resource still says 'VLAN' in log even if VXLAN is used
- in UI, "Network - GuestNetworks" dosen't display VNI
-- VLAN ID field displays "N/A"
- Documentation!
