After HV reboot and VM failover, the VM experiences random packet loss and network latency.
OnApp 3.x, 4.x
1. Check the alerts page for zombie virtual servers. This can cause traffic to be routed to an instance of the VM where the networking is not set up properly. Shutting down zombie instances can correct routing issues
2. Check iptables and arptables FORWARD chains on all hypervisors to ensure that rules only exist for the IP address on the hypervisor where the VM is running. If there are rules for the IP on other hypervisor they will need to be removed to ensure traffic is only routed to the host HV. To search for rules use the following examples
# iptables -L --line-numbers -n | grep x.x.x.x
# arptables -L --line-numbers -n | grep x.x.x.x
