If you want to upgrade your CentOS 6 VPS to CentOS 6.5 (currently in CR repo), here is a workaround which you need to apply, otherwise the networking of your upgraded VPS will break after you reboot it.
You must do this after you run "yum update" and before you reboot the VPS:
wget https://www.fitvps.com/dl/ifup-eth
mv -f ifup-eth /etc/sysconfig/network-scripts/ifup-eth
chmod 755 /etc/sysconfig/network-scripts/ifup-eth
chattr +i /etc/sysconfig/network-scripts/ifup-eth
If you don't do this before rebooting, after reboot your VPS will not bring up the networking and you will not be able to ssh in.
