Hello Anyone have faced this problem? CS4.02 KVM Advanced Network, VM instance can not access public IP. NAT(Source)
That the VM instance running, but inside the VM instance, it is not possible to access outside. It can ping VMs each other, It can ping google.com in the* Virtual Router VM.* But just can not ping Google.com inside the VM instance. Seems inside the VM instance, It can resolve the Google.com 's IP address. BUT can not do others. Please see the following output. ------------------------ [root@CentOS5-5 ~]# wget www.google.com --2013-05-21 08:30:39-- http://www.google.com/ Resolving www.google.com... 173.194.64.104, 173.194.64.99, 173.194.64.105, ...
