Good morning ,

Two questions,

1. What Hypervisor are you using? - security groups only work with Xenserver and KVM,  
2. Have you look at using Advanced networking?  , it gives you more functions , separate networks
for traffic, public and private networks (Used if you are wanting a public cloud), DHCP ,
VPC's , VPN gateways

Subject: Guest networking issue

Hi Hope someone can help me on this

 Below is my env

a) CloudStack 4.9 on CentOs 7.2,
b) running on 2 compute nodes and one controller node
c) NFS as shared storage primary and secondary
d) Basic networking
f) Hosts, Guests, system VMs and NFS storage are in same IP range

I can create VMs and from UI I can see Guests are getting IPs assigned

     1. when the instance boots up it has no IP assigned (ip addr show shows no IP). But I
have to do dhclient for the guest to get configured.

     2. Even though instance gets an IP after running dhclient, I am unable to reach no further
than the host that the instance are in. All the routes are in place. I have created Security
Group with allow all to this guest still no luck

please let me know if you need any additional information

Best Regards
