Does KVM need 64 bit for good performance?
I am looking at setting up a couple of KVM (Kernel Virtual Machine) based virtual servers. They will have dual quad core Xeon processors and about 16GB of ram. I am partial to Slackware but am wondering if this is not a good fit for Slack. I know I can access the large memory with kernel options on a 32 bit system, but would I see a substantial improvement in performance by going to a 64 bit system?
Just to clarify, the systems I intend to virtualize would all be 32 bit based and not need more than 3GB of ram.
