I have installed CentOS 7 x64 on VMware workstation 12.0, I built wordpress website on it and then after my colleague finished his decorative work, I used VMware vCenter Converter Standalone Client 6.0 to move it to an ESXi 5.5 host. Since I moved it, the server is most of the time losing network connectivity. When I ping it, I get request timed out. I have to keep turning the NIC off/on to retain connectivity. When I open the website, I get a white empty page. I am unable to SSH the server as well.
I have many other servers that I installed on ESXi 5.5 since the very first moment, contrary to this server which I built on workstation 12.0 then moved it to ESXi 5.5. The VM machine version is 8.0, if I remember it rightly.
I removed the network card from the machine, deleted NIC file from network-scripts directory, rebooted the machine, added a new NIC, still the same issue. How can I troubleshoot such issues? Any clues on what's going on with this server.
