Dears,

I launched ubuntu/fedora VM Instances, Now i did ssh to one of the VM instance and ping to google.com

root@ubuntu-vm:~# ping google.com

PING google.com (74.125.236.164) 56(84) bytes of data. 64 bytes from maa03s16-in-f4.1e100.net (74.125.236.164): icmp_req=1 ttl=56 time=41.5 ms 64 bytes from maa03s16-in-f4.1e100.net (74.125.236.164): icmp_req=2 ttl=56 time=91.4 ms 64 bytes from maa03s16-in-f4.1e100.net (74.125.236.164): icmp_req=3 ttl=56 time=37.2 ms 64 bytes from maa03s16-in-f4.1e100.net (74.125.236.164): icmp_req=4 ttl=56 time=39.7 ms

--- google.com ping statistics --- 40 packets transmitted, 40 received, 0% packet loss, time 211814ms rtt min/avg/max/mdev = 35.694/86.999/777.840/158.729 ms

I am getting a late response.

What are the things we need to check for troubleshoot. My physical hosts are getting the quick response. Only vm Instances are getting late response. IS it depends on configuration?

Regards,
RHK

Hello,

There are a lot of reason which can cause this. When I tried to ping google from my instance on our XEN-Server (in Germany) he tried to go to "173.194.70.94". It took each request around 6 ms. Quite Okay. But if I try to ping your google server (74.125.236.164) it takes each request 300 to 400 ms.

The simplest solution could be that you just connected to a google server which is very far away or that your network is overloaded. So just try to connect to near hosts (maybe local, then one where you now that it is in the same city/country). You can also try tracepath to see on which hop it takes so long.

Otherwise we need more Information about your Environment you are working in: e.g. which host do you use, how did you setup network, configs etc.
