I tried restarting network - systemctl restart network.service then connection was restored again for few minutes Finally I could restore connection by restarting iptables - systemctl restart iptables.service But then again guest VMs lost connection after few minutes of normal operation. The time of normal operation can be 5 minutes, but sometimes up to 40 minutes. Please help me to track the root cause and fix it Host OS - Centos 7.5 virtualisation - KVM --000000000000e90bf405716972fa--
