I have CentOS 6.4 on which i am running virtual box. Inside virtualBox i have CentOS based VM which works perfectly fine. The NAT and HostOnly interface have assinged IP Addresses through DHCP and they work just fine.
However i create some internal network interfaces and add custom IP Addresses. It works fine but later after sometime suddenly those IP Addresses are removed automatically. I have no idea why this happens, and because of this my communication stops. I simply statically assign the IP address again and it starts working again which later after sometime, (appox 25 seconds) the configurations are disappeared and interface is left without any ip address.
What could be the problem? your help would be much appreciated.
