If I have correctly understood CloudStack architecture GSon is generated by the manager running in the tomcat server. So virtual scripts for the VPC are ok. was (Author: aurryon): The IP is always assigned to the last ethX device > Extra acquired public ip is assigned to wrong eth device > -------------------------------------------------------- > > Key: CLOUDSTACK-8699 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8699 > Project: CloudStack > Issue Type: Bug > Security Level: Public(Anyone can view this level - this is the > default.) > Components: Virtual Router > Affects Versions: 4.4.4 > Environment: KVM on CentOS > Reporter: Remi Bergsma > > When the public network of a zone is untagged, an extra public ip address is > bound to the wrong interface (eth2 instead of eth1). > Example: > root@r-44137-VM:~# ip a > 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN > link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 > inet 127.0.0.1/8 scope host lo > 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP > qlen 1000 > link/ether 0e:00:a9:fe:01:eb brd ff:ff:ff:ff:ff:ff > inet 169.254.1.235/16 brd 169.254.255.255 scope global eth0 > 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP > qlen 1000 > link/ether 06:46:32:00:00:8d brd ff:ff:ff:ff:ff:ff > inet xx.22.37.143/25 brd 85.222.237.255 scope global eth1 > 4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP > qlen 1000 > link/ether 02:00:51:27:00:02 brd ff:ff:ff:ff:ff:ff > inet 10.0.0.1/24 brd 10.0.0.255 scope global eth2 > inet xx.22.37.145/25 brd 85.222.237.255 scope global eth2 > Obviously, this does not work. > # MGT server > 2015-07-31 13:08:12,330 DEBUG [agent.manager.ClusteredAgentAttache] > (API-Job-Executor-98:ctx-cbf1e352 job-799791 ctx-58cb236f) Seq > 437-2425751349292433542: Forwarding Seq 437-2425751349292433542: { Cmd , > MgmtId: 345052433506, via: > 437(mccxpod01-hv03.mccxpod01.mccx-shared-2.mccx.mcinfra.net), Ver: v1, Flags: > 100001, > [{"com.cloud.agent.api.routing.SetPortForwardingRulesVpcCommand":{"rules":[{"dstIp":"10.0.0.61","dstPortRange":[22,22],"id":54859,"srcIp":"xx.22.37.145","protocol":"tcp","srcPortRange":[22,22],"revoked":false,"alreadyAdded":false,"purpose":"PortForwarding","defaultEgressPolicy":false}],"accessDetails":{"zone.network.type":"Advanced","router.name":"r-44137-VM","router.ip":"169.254.1.235","router.guest.ip":"10.0.0.1"},"wait":0}}] > } to 345052433504 > 2015-07-31 13:08:12,457 DEBUG [agent.transport.Request] > (AgentManager-Handler-58:null) Seq 437-2425751349292433542: Processing: { > Ans: , MgmtId: 345052433506, via: 437, Ver: v1, Flags: 0, > [{"com.cloud.agent.api.Answer":{"result":true,"details":"","wait":0}}] } > 2015-07-31 13:08:12,457 DEBUG [agent.transport.Request] > (API-Job-Executor-98:ctx-cbf1e352 job-799791 ctx-58cb236f) Seq > 437-2425751349292433542: Received: { Ans: , MgmtId: 345052433506, via: 437, > Ver: v1, Flags: 0, { Answer } } > # AGENT > 2015-07-31 13:08:12,203 DEBUG [cloud.agent.Agent] > (agentRequest-Handler-4:null) Request:Seq 437-2425751349292433541: { Cmd , > MgmtId: 345052433506, via: 437, Ver: v1, Flags: 100001, > [{"com.cloud.agent.api.rout > ing.IpAssocVpcCommand":{"ipAddresses":[{"accountId":625,"publicIp":"xx.22.37.145","sourceNat":false,"add":true,"oneToOneNat":false,"firstIP":false,"broadcastUri":"vlan://untagged","vlanGateway":"xx.22.37.1 > 29","vlanNetmask":"255.255.255.128","vifMacAddress":"06:46:32:00:00:8d","networkRate":-1,"trafficType":"Public","networkName":"pubbr0","newNic":false}],"accessDetails":{"router.guest.ip":"xx.22.37.143","zone > .network.type":"Advanced","router.ip":"169.254.1.235","router.name":"r-44137-VM"},"wait":0}}] > } > 2015-07-31 13:08:12,204 DEBUG [cloud.agent.Agent] > (agentRequest-Handler-4:null) Processing command: > com.cloud.agent.api.routing.IpAssocVpcCommand > 2015-07-31 13:08:12,206 DEBUG [kvm.resource.LibvirtComputingResource] > (agentRequest-Handler-4:null) Executing: > /usr/share/cloudstack-common/scripts/network/domr/router_proxy.sh > vpc_ipassoc.sh 169.254.1.235 -A > -l xx.22.37.145 -c eth2 -g xx.22.37.129 -m 25 -n xx.22.37.128 > As you see, the vpc_assoc.sh script is instructed to use the wrong eth > interface. > See also: > core/src/com/cloud/agent/resource/virtualnetwork/VirtualRoutingResource.java > api/src/com/cloud/agent/api/to/IpAddressTO.java -- This message was sent by Atlassian JIRA (v6.3.15#6346)
