Hi Philip Viktor's advice really sums it up.
Since this is a network operator's list, I'll dig a little bit more into the network part: You probably want to invest some time to separate the network, implement QoS, configure firewalls and design for redundancy (also first hop redundancy such as HSRP), especially if you use IP based storage on a shared network, depending on how reliable and secure you want your network to be. Also if you grant control of the network interface to your clients (be it virtual or not) you probably want to take a look at private VLANs, ARP inspection, IP source guard and DHCP snooping or similar techniques to secure your network and prevent IP address waste. Bear in mind that you may loose some functionality with such virtualization technologies like IPSec VPNs inside virtual containers ... Oh and don't forget IPv6 :) Regards - Mathias On 4 May 2011, at 11:03, Philip Iezzi wrote: > Hi > > As a small web hosting provider we are planning to switch from physical-only > servers to virtualization.
