Hello all, We have observed recurring issue that has been observed recently in the CloudStack environment we use for hosting virtual machines.
Specifically, we have identified that certain Virtual Routers lose internet connectivity, which causes disruptions to services such as VPNs and other network-dependent functions. This issue was first noticed with the infrastructure of the customer1 vpc. For the customer2 vpc case, we resolved the issue by recreating the VPC along with the associated guest networks. 1. Connectivity Issues: Check IP Ranges and Netmasks: Connectivity Checks: We use ping, arping, and traceroute within the virtual router to test connectivity to other VMs and external networks. Virtual Router Diagnostics: we did run "Run Diagnostics" and "Get Diagnostics" features as well but not getting any result. 2. Virtual Router Issues: Force Stop and Restart: We have tried but no luck. Destroy and Recreate: We have tried but no luck. DHCP Problems: There is no issue with dhcp. 3. Network Configuration: Network connection also ok. Any help would be really appreciated. Thank you! Regars, SK
