Summary
VMware's long standing virtual history has given the ESX product ample time to mature to a very stable, usable product.
The dribbleware nature of the release of virtualization products from Microsoft -- with Hyper-V, the Linux Interface Connector Kit (LinuxIC) and SC-VMM 2008 arriving six months, eight months and 10 months after Windows 2008 Server editions hit the streets — certainly won’t help with the rapid deployment of Hyper-V into environments where it will earn its chops. Microsoft’s development power is obvious, but the devil will be in the technical details as Microsoft plays catch up in the explosive virtualization marketplace.
