That sounds scary. Ok, so I am coming away with a vCPU is = to a thread. RAM is fixed. I read Proxmox requires 2GB of RAM and I was unable to determine the number of cores for Proxmox. Proxmox says you will need Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag. They suggest SSD disks, and redundant Gbit NICs. I assume along these lines you would want redundant power supplies. Another Question : I have a Cox business connection that allows me to run servers and to be allocated more than 1 static IP. I can see me configuring at least 4 virtual machines for LAMP - PHP testing and development, and a VM for a real website. Not all of these VMs would be active at once. Since I would be running this out of my home office, to be safe, I would need enough RAM to allocate 4GB of RAM of reach _active_ VM and 2 vCPUs, and to be safe maybe 4GB of ram and 2 cores for Proxmox. For 4 simultaneously active VMs I would need 8vCPUs (8 threads) and 4GB of RAM each or 16GB of RAM. Add to that 2 Cores/4 threads and 4GB of RAM for Proxmox and I would need 12 threads or 6 cores and 20GB of RAM. I'm thinking a 500GB SSD would be enough and if I like I could add a redundant NIC and a redundant power supply. Pretty much a consumer grade box? Your thoughts?
