I guess it is because the virtual nic (vnet25 ?) for public interface of s-10-VM is on you can go to the Zone-> Physical network, and update the traffic label of Public traffic to "cloudbr1" and retry |

It is strange that ssvm works but cpvm does not. I recalled an issue with CKS which is caused by sysctl settings for arp #9186 You can also check the sysctl settings on kvm host and in the system vms

@weizhouapache Thanks for helping me to resolve the issue . I have disconnected and reconnected the portgroup in vm level is able to solve this gateway ping issue. I can able to ping both gateways. The only issue i 'm facing right now is console proxy vm is not able to find the nfs storage, even i can able to ping the IP. SSvm looks good. routing table is same for both root@v-22-VM:~# /usr/local/cloud/systemvm/ssvm-check.shFirst DNS server is 66.173.144.10
