##### SUMMARY
<!-- Explain the problem/feature briefly -->
I am trying to get NFS storage on the ACS VM. But VM virtual routers don't
have a route or interface to that.
I am running the environment as below:
ACS Portal: 10.10.40.252
NFS server: 10.10.40.250
KVM host: 172.16.0.100 (Have to NIC 1 for local and 1 for public configured
as cloudbr0 for private and cloudbr1 as public.)
ACS Management Range: 172.16.0.10–172.16.0.50 (cloudbr0)
ACS Public Range: 232.28.15.16 - 232.28.15.23 (cloudbr1)
I had trunked KVM Privet NIC to talk to the ACS and NFS subnets. So through
172.16.0.0, I can communicate with the 10.10.40.0 network.
I bring up a VM with isolated network 10.1.1.5 and it creates VR with
10.1.1.1 and 232.28.15.19. I am getting internet, and the rest is fine.
I need to mount NFS server with this VM. While checking the VR route, I can
see the default route to the public NIC. Through that NIC, I won't get the
10.10.40.250 system as it passed out from KVM through cloudbr1.
It is not advised to trunk KVM host cloudbr1 NIC and allow 10.10.40.250
traffic to route through the public network. What will be the best solution for
this in this case?
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
Most of the production environment ACS will be running on a DC, which will
have a NAS or SAN for NFS storage and which will be on some other LAN vlan. I
can see an option like configuring VPC and adding site-site VPN. But in most
cases, all devices have the same DC, which will affect NFS performance when
traffic moves out and in through a VPN. So CloudStack should have some option
to add this storage to VMs and Kubernetes clusters.
