Subject [jira] [Commented] (CLOUDSTACK-2328) Linux native VXLAN support on KVM hypervisor
Date Thu, 26 Sep 2013 18:04:04 GMT


ASF subversion and git services commented on CLOUDSTACK-2328:

Commit a45ee749ace84a88e8f0b4c50ade59f71d45e89e in branch refs/heads/ui-restyle from ynojima
[;h=a45ee74 ]

CLOUDSTACK-2328: Linux native VXLAN support on KVM hypervisor

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 script that handle bridge/vxlan interface manipulation script
-- Usage is exactly same to
- BridgeVifDriver will call instead of when VXLAN is used for

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!
