Hello Wei. Thank you for your suggestion. I moved the second KVM nic to a
different subnet and reprovisioned the Zone with new public and guest IPs.
However, the system VMs still cannot access the network.
Is there any sysctl settings that could be blocking this? The KVM installation
guide and CloudStack guide don’t mention any changes to sysctl settings.

Hi,
In ssvm, the eth1 has ip
10.120.123.166/22<http://10.120.123.166/22>, eth2 has ip
10.120.123.160/22<http://10.120.123.160/22>
They are in same subnet, but.. it seems eth1 is on cloudbr0 and eth2 is on
cloudbr1.
I think they should use ips in different subnet, or on same bridge (network
traffic label)
