Sandeep, This looks like a network configuration issue to me. Looking at your routing table, the 2 DNS servers having the IPs 10.4.21.4 and 103.15.60.4 have a host specific route using the eth1 device: > 10.4.21.4 10.4.6.1 255.255.255.255 UGH 0 0 0 eth1 > 103.15.60.4 10.4.6.1 255.255.255.255 UGH 0 0 0 eth1 Would you know which physical interface on the hypervisor is bridged to SSVM’s eth1? You can run the “brctl show” command on the hypervisor to get this information. > If I ping from my machine it is working properly, > > root@cloudstack# ping 10.4.21.4 > > PING 10.4.21.4 (10.4.21.4) 56(84) bytes of data. > 64 bytes from 10.4.21.4: icmp_req=1 ttl=127 time=32.3 ms > 64 bytes from 10.4.21.4: icmp_req=2 ttl=127 time=0.824 ms > 64 bytes from 10.4.21.4: icmp_req=3 ttl=127 time=4.08 ms > ^C > > --- 10.4.21.4 ping statistics --- > 3 packets transmitted, 3 received, 0% packet loss, time 2000ms > rtt min/avg/max/mdev = 0.824/12.420/32.350/14.155 ms > > Troublesome to understand now. A Virtual Machine’s networking is very different from the physical hosts networking. A physical bridge has to configured with the right label to assist cloudstack in mapping a VMs interface(s) to the right physical interface. If the mapping is incorrect, then networking will generally fail.
