##### ISSUE TYPE <!-- Pick one below and delete the rest --> * Bug Report * Other ##### COMPONENT NAME ~~~ VR and instances ~~~ ##### CLOUDSTACK VERSION ~~~ 4.19.0.1 ~~~ ##### CONFIGURATION ~~~ management server ip address : 10.0.1.10 gateway : 10.0.1.1 host machine 1 ip : 10.0.1.18 host machine 2 ip : 10.0.1.12 guest network ip range : 10.1.1.0/24 virtual router public ip address : 10.0.1.32 virtual machine on host machine 1(10.0.1.18) : 10.1.1.96 virtual machine on host machine 2(10.0.1.12) : 10.1.1.158 hypervisor type : KVM ~~~   ##### OS / ENVIRONMENT ~~~ kvm setup on ubuntu 22.04 ~~~ ##### SUMMARY <!-- Explain the problem/feature briefly --> ~~~ We setup new cloudstack on ubuntu 22.04 with advanced networking. Added two hosts in the same zone, same pod and same cluster successfully. later created isolated network and using ubuntu iso template created two virtual machines one on each hosts. later we are trying to ping from one vm to another, it says network unreachable. ~~~  <!-- You can also paste gist.github.com links for larger files --> ##### EXPECTED RESULTS <!-- What did you expect to happen when running the steps above? --> ~~~ ubuntu-dev-vm-1 should be able to ping the virtual machine >>>>> ubuntu-dev-vm-2 ~~~ ##### ACTUAL RESULTS <!-- What actually happened? --> ~~~ PING 10.1.1.158 (10.1.1.158) 56(84) bytes of data. >From 10.1.1.96 icmp_seq=1 Destination Host Unreachable ~~~ ### Screenshots virtual router is running on the host 1 machine. when we run diagnostics to ping from virtual router to the VM(10.1.1.158) the says network unreachable.  On one host machine I have created the vm and that also have virtual router, for this case the router is able to ping the same VM(10.1.1.96).
