Hi Ron, Your configuration seems to be applied correctly on the hypervisor. Could you ping your DNS from SSVM and check the packets on ens192 on the KVM host?

My issue is that after creating the Zone in the web UI, the Agent State for the secondarystoragevm and consoleproxy is greyed out. The agent state is Running for both. Following the troubleshooting guide, it appears that the system VMs are not able to connect to the local network through the hosts bridged interface. The hypervisor host is RHEL 8.7 with KVM. Details: Have 3 VMs: One running the management server and mysql database, the second is the primary and secondary NFS server, and the third is the RHEL 8.7 KVM hypervisor host. Followed the installation instructions at http://docs.cloudstack.apache.org/en/latest/installguide/hypervisor/kvm.html to set up the KVM hypervisor host. Hypervisor host has 2 NICs: first one configured for cloudbr0 and the management interface, second one configured for cloudbr1 and the guest and public interfaces. Firewalls on all 3 VMs have been disabled for testing. All 3 VMs are on the same subnet. When adding the Zone, I selected Core zone, Advanced core zone type, added 2 physical networks with VLAN isolation method (first one configured with management traffic over cloudbr0, second one with guest and public both on cloudbr1). For the public traffic, the gateway is 10.120.120.1, netmask 255.255.252.0, start IP 10.120.123.159, end IP 10.120.123.163, and VLAN left blank (The local network doesn't require VLANs). For the pod, the reserved gateway is 10.120.120.1, netmask 255.255.252.0, reserved system start IP 10.120.123.164, reserved system end IP 10.120.123.168. When I connect into the SSVM and run /usr/local/cloud/systemvm/ssvm-check.sh, I get: root@s-2-VM:~# /usr/local/cloud/systemvm/ssvm-check.sh ================================================ First DNS server is 172.18.5.71 PING 172.18.5.71 (172.18.5.71): 56 data bytes --- 172.18.5.71 ping statistics --- 2 packets transmitted, 0 packets received, 100% packet loss WARNING: cannot ping DNS server route follows Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.120.120.1 0.0.0.0 UG 0 0 0 eth2 10.120.120.0 0.0.0.0 255.255.252.0 U 0 0 0 eth1 10.120.120.0 0.0.0.0 255.255.252.0 U 0 0 0 eth2 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 172.18.5.71 10.120.120.1 255.255.255.255 UGH 0 0 0 eth1 ================================================ ERROR: DNS not resolving cloudstack.apache.org resolv.conf follows nameserver 172.18.5.71 nameserver 172.18.5.71 nameserver 172.18.5.72 root@s-2-VM:~# ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 0e:00:a9:fe:a2:f8 brd ff:ff:ff:ff:ff:ff altname enp0s3 altname ens3 inet 169.254.162.248/16 brd 169.254.255.255 scope global eth0 valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 1e:00:9d:00:00:03 brd ff:ff:ff:ff:ff:ff altname enp0s4 altname ens4 inet 10.120.123.166/22 brd 10.120.123.255 scope global eth1 valid_lft forever preferred_lft forever 4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 1e:00:8f:00:00:07 brd ff:ff:ff:ff:ff:ff altname enp0s5 altname ens5 inet 10.120.123.160/22 brd 10.120.123.255 scope global eth2 valid_lft forever preferred_lft forever On the KVM hypervisor host on which the SSVM is running: $ brctl show bridge name bridge id STP enabled interfaces cloud0 8000.fe00a9fe4377 no vnet0 vnet3 cloudbr0 8000.00505688729b yes ens192 vnet1 vnet4 cloudbr1 8000.0050568829ca yes ens224 vnet2 vnet5 The management server log doesn't log any errors when deploying the system VMs. The hypervisor host agent log shows the following: 2023-05-01 09:24:31,974 WARN [kvm.resource.LibvirtKvmAgentHook] (agentRequest-Handler-3:null) (logid:8bbb4904) Groovy script '/etc/cloudstack/agent/hooks/libvirt-vm-state-change.groovy' is not available.
