Virtualization vendors may be promoting the potential of putting 20, 50, or even 100 virtual machines on a single physical server, but IT managers and industry experts say these ratios are dangerous in a production environment, causing performance problems or worse disruption issues. In the test and development environment, companies can put 50 virtual machines in a single physical host, said Andimann, vice president for research at Colorado State Boulder's Business Management Association (EMA). However, when it comes to important tasks and resource-intensive applications, the virtual machine ...
