stock was rising more than 5% early Tuesday after the virtualization-software seller unveiled VMware Server 2, the next generation version of its virtualization product.
VMware Server 2 enables users to set up new server capacity by partitioning a physical server into multiple virtual machines. The idea is to help businesses make better use of and simplify their information technology assets.
Shares of VMware were up $4.02 at $84.38 in premarket trading.
The company said a beta version of VMware Server 2 for Linux and Windows is available for download from its Web site.
