ABSTRACT
When planning your virtual machine resource requirements you should look at any existing installations on physical systems when possible for benchmarks. The resources needed to support the operating system and applications on a physical server should equate to similar requirements for your
virtual machine. You should have an idea before building your VM as to the following resource requirements to meet your needs:
• Number of virtual processors (choose more than one virtual CPU if your applications support multi-threading)
• Total processing power needed (in MHz) to support OS and application requirements • Total memory needed (in MBytes) to support OS and application requirements • Total number of virtual networking adapters to support networking requirements • Total number of virtual host bus adapters needed (more than one if multi-pathing is needed
for redundancy)
• Total number of virtual hard disks and size required to support file systems and storage requirements
• Total number of virtual CDROM devices needed to support OS and application requirements • Total number of virtual floppy devices needed to support OS and application requirements • Guest OS licensing requirements
You can reconfigure your virtual machine after it has been built and has an OS installed in it, but only virtual disks can be added while the guest OS is running.
