RHEV is excellent due to cost, performance and security.
What is most valuable?
RHEV costs are very low compared to other Virtualization products. RHEV hypervisor supports up to 160 cores and up to 2 TB of RAM on a host machine. Performance and security are key advantages of RHEV. One of the new features are transparent huge pages, where kernel dynamically creates large memory pages for virtual machines, which improves performance for most workloads by reducing the number of times that memory is accessed. It is open source, which means that it is available for use by every one. There is a “Power user portal” feature that helps developer and IT staff with a self-service interface that allows them to provision virtual machines, define templates, and be an administrator to their own environment.
What needs improvement?
You need to buy support from red hat and you need to renew support every year in order to keep getting support from red hat. Some features are unavailable compared to leading visualization products. RHEV hyper-visor came later into the market than other leading visualization product.
What other advice do I have?
RHEV hyper visor is a cost effective solution for virtualization. Its work on kernel base virtualization systems. Its usage keep growing in the market.
