bug 12318: NaaS: Dynamic CIDR for virtual router
This patch in fact use ExternalGuestNetworkGuru to replace GuestNetworkGuru. The
problem is the virtual router would normally use 10.1.1.0/8 as CIDR, but when we
want to upgrade to external firewall e.g. Netscaler, the CIDR would need to be
changed to different value e.g. 10.x.x.0/24 based on VLAN, because the external
firewall can not support one CIDR for multiply VLAN right now. So we have to use
the same policy for virtual router.
This patch also add one field "specified_cidr" to the networks table. If this
field is true, then it means user specify the CIDR of this network, thus we can
not granutee the CIDR after upgrade is valid, so we would like to prohibit the
upgrade of network offering.
This should also fix bug 12318. The reason for bug 12318 is the pre-set gateway
address of domR is overrided by ExternalGuestNetworkGuru. After this patch,
ExternalGuestNetworkGuru would respect the existed value in Nic, rather than
simply wiping it out. It would do calcuation to get the relevant address after
VLAN changed.
More clean up can be done in the future, when we proved that this policy change
doesn't break...
status 12234: resolved fixed
status 12318: resolved fixed
* can be specified for Shared network only
* if not specified for the Shared networks, try to locate it based on the zoneId and tags. If tags is not null, pick up first physicalNetwork from the zone that has matching tags. If tags is null, and there are none/more than 1 physical netwroks in the zone, error out.
- Create Zone changes and changes to data_center table to remove vlan, securityGroup fields
- Physical Network lifecycle APIs
- Physical Network Service Provider APIs
- DB schema changes
Block update only in these cases:
* when DNS capability AllowDnsSuffixModification is false for the network
* when target network has running network elements (dhcps or domRs)

This patch enable redundant virtual routers.
1. To enable this feature, db need to be updated using follow SQL by now(we
would get a UI way later):
UPDATE network_offerings SET redundant_router=1 WHERE guest_type="Virtual" AND
system_only=0;
2. System would try to start up two routers at different hosts. But if there is
only one host in the zone, system would start up two routers on it.
3. The failover part is using keepalived, and connection tracking part is using
conntrackd. There would be one master router and one backup router. The status
of router(master or backup) can be query from the database table domain_router
now. Management server would update the status every 30s by default.
4. The routers for the same zone would use same external NIC(same ip and mac).
The script used for fail-over would ensure only one external NIC present in the
network at any time.
5. Currently management server don't got the ability to stop one of router is
both of them reported as master. The feature is in the todo list.
After two routers start up, disconnect anyone of them, the guest network
shouldn't be affected, and established connection(http, ssh, etc.) should still
works. The fail-over on gateway part should be 3~4 seconds.
Currently the patch works with KVM. Would deal with vmware and XenServer soon.
2) Set traffic Type to be Guest for Direct/Virtual non-system default network offerings. Use this guestIpType during the network creation/implementation

Changes to destroyNetwork process. Here are the steps:
* shutdown network - shutdowns all network elements (domRs/Dhcps)
* delete network - destroy all network elements, cleanup network's resources (vlans, ip ranges), mark network with Destroyed state and set Removed field
