This feature allows CloudStack administrators to create layer 2 networks on CloudStack. As these networks are purely layer 2, they don't require IP addresses or Virtual Router, only VLAN is necessary (provided by administrator or assigned by CloudStack). Also, network services should be handled externally, e.g. DNS, DHCP, as they are not provided by L2 networks.
As a consequence, a new Guest Network type is created within CloudStack: L2
Description:
Network offerings and networks support new guest type: L2.
L2 Network offering creation allows administrator to select Specify VLAN or let CloudStack assign it dynamically.
L2 Network creation allows administrator to specify VLAN tag (if network offerings allows it) or simply create network.
VM deployments on L2 networks:
VMs should not IP addresses or any network service
No Virtual Router deployed on network
If Specify VLAN = true for network offering, network gets implemented using a dynamically assigned VLAN
UI changes
A new button is added on Networks tab, available for admins, to allow L2 networks creation
Added ability to specify mac in deployVirtualMachine and
addNicToVirtualMachine api endpoints.
Validates mac address to be in the form of:
aa:bb:cc:dd:ee:ff , aa-bb-cc-dd-ee-ff , or aa.bb.cc.dd.ee.ff.
Ensures that mac address is a Unicast mac.
Ensures that the mac address is not already allocated for the
specified network.
There are some VM deployment failures happening when multiple VMs are deployed at a time, failures mainly due to NetworkModel code that iterates over all the vlans in the pod. This causes each deployVM thread to hold the global lock on Network longer and cause delays. This delay in turn causes more threads to choose same host and fail since capacity is not available on that host.
Following are some changes required to be done to reduce delays during VM deployments which in turn causes some vm deployment failures when multiple VMs are launched at a time.
In Planner, remove the clusters that do not contain a host with matching service offering tag. This will save some iterations over clusters that dont have matching tagged host
In NetworkModel, do not query the vlans for the pod within the loop. Also optimized the logic to query the ip/ipv6
In DeploymentPlanningManagerImpl, do not process the affinity group if the plan has hostId provided.

even the normal build is broken as reported by @koushik-das on dev list

Changed methodnames according to Nic.java refactor.
Fixed NicVO.java due to regression from Nic.java refactor.
Fixed VmWareGuru.java after Nic.java refactor.
See issue CLOUDSTACK-8736 for ongoing effort to clean up network code.
This is a plugin that puts in ovm3 support ranging from 3.3.1 to 3.3.2. Basic
functionality is in here, advanced networking etc..
Snapshots only work when a VM is stopped now due to the semantics of OVM's raw
image implementation (so snapshots should work on a storage level underneath the
hypervisor shrug)
This closes#113

This reverts commit 709bf074de9f8f22e6a71362551c4867be884e4b.
Network GC is broken with out-of-band VM movements due to the original commit, so reverting.
restart, firewall rules dropped from iptables post restart
on VR restart, not all public IP's associated with the network are sent
with IpAssocCmd to VR. This fix will ensure all the ip's associated with
the network irrespective of the account are sent as part of
IpAssocCommand
Conflicts:

1. Egress default policy rules is send to the firewall provider. It is up to the
provider to configure the rules.
2. The default policy rules are send for both allow and deny default policy.
3. On network shutdown rules for delete are send.
4. For VR and SRX, by default deny the traffic. So no default rule to deny traffic is required.
