does hosts and managementserver have to be in same subnet?
Hello All,
I have a management having ip 172.31.101.202 having a network 172.31.100.0
and subnet of 255.255.252.0. The default gateway is at 172.31.100.1
The private ip range in the zone is 172.31.101.210 - 172.31.101.220 and
guests ip range is 172.31.101.230 - 172.31.101.250
The management server also acts as a host and has a VM running. Through
this VM I can connect to the internet and ping other systems all over the
network
Now I added a host to this zone having ip 172.31.132.131, network
172.31.132.0, gateway 172.31.132.1 and subnet 255.255.252.0. The host added
succesfully to the same cluster as the previous host. Now when I create a
VM on this host it is given a IP from the guest ip range i.e 172.31.101.0
network..But from this VM I cannot access either the internet or any other
machine.
Am I somewhere wrong here? Do I need to create a seperate cluster for the
hosts in the other subnet?
Regards

Hi,
Hosts in a pod or cluster must be in the same subnet. In your case is the guest cidr tagged? If yes you need to configure the tagged vlan as native vlan on the switch ports where the hosts are connected.
Thanks,
Sanjeev

Hi Somesh,
I did a bit of tweakng to understand the issue.
I created a VM on first host and it could successfully access the network.
Now I migrated this VM to another host and the network access got denied.
I would like to draw your attention here to the fact that *both my host though being in different subnets physically I have added them to the same cluster. Is it wrong or right?* The first host where the VM could access the network is in the same subnet as the guest ip addresses. But the second host where the VM cannot access the network is in different subnet than that of the guest ip ranges.

Well, I can tell you this, it is not required that the hypervisor hosts and mgmt. be in the same subnet. If you scale your environment you'll realize that won't actually be possible to have such a configuration. So you got to look at your networking. I can tell you that your gateway/s may not be correctly configured.

Yeah the gateway is working cool...the vm on the first host can access the
network ithout any problems...its the prob on the second vm whose host is
in a different subnet than the gyest ip range that is not able to access
the network...
What more data can i provide for aomeone to help ke through this???

Not really.
Make sure your gateway for the given network is correctly routing the traffic. Since you are using Basic network, CS isn't really controlling how guest traffic is routed.
