The Snapshot Manager in VMware Workstation 6

VMware Workstation is a virtual machine software suite for x86 and x86-64 computers from VMware, a division of EMC Corporation. This software suite allows users to set up multiple x86 and x86-64 virtual computers and to use one or more of these virtual machines simultaneously with the hosting operating system. Each virtual machine instance can execute its own guest operating system, such as Windows, Linux, BSD variants, or others. In simple terms, VMware Workstation allows one physical machine to run multiple operating systems simultaneously. Other VMware products help manage or migrate VMware virtual machines across multiple host machines. Besides bridging to existing host network adapters, CD-ROM devices, hard disk drives, and USB devices, VMware Workstation also provides the ability to simulate some hardware. For example, it can mount an ISO file as a CD-ROM, and .vmdk files as hard disks; and can configure its network adapter driver to use network address translation (NAT) through the host machine rather than bridging through it (which would require an IP address for each guest machine on the host network). VMware Workstation also allows the testing of live CDs without first burning them onto physical discs or rebooting the computer. One can also take multiple successive snapshots of an operating system running under VMware Workstation. Each snapshot allows you to roll back the virtual machine to the saved status at any time. The ability to use multiple snapshots makes VMware Workstation useful as a tool for salespersons demonstrating complex software products, and for developers setting up virtual development or test environments. VMware Workstation includes the ability to designate multiple virtual machines as a team which administrators can then power on and off, suspend, and resume as a single object — making it particularly useful for testing client-server environments.

[edit] Known issues

Known limitations of VMware Workstation, as of June, 2008^[update], include the following:

[edit] Hardware support

VMware virtual machines do not directly support FireWire.^[11]
VMware Workstation cannot use more than 2 CPUs (or cores) per virtual machine. This means that a single virtual machine cannot use the full power of the underlying hardware on machines with the total number of cores greater than 2 (Quad Core 2, or 2 x Core 2). This is true also for the last version 6.5.
VMware virtual machines provide only experimental support for 3D hardware acceleration, via Microsoft's Direct3D 8 API.^[12]^[13] A video has appeared on YouTube that demonstrates several 3D-accelerated games running under VMware Fusion and Mac OS X. The release notes for Fusion beta 2 include a list of 3D-accelerated computer games that can run within Windows XP-based virtual machines. In version 6.5, Direct3D 9.0 API support (up to Shader Model 2.0) is provided on Windows XP guests and on any host OS.
Five-button mouse is supported in version 6.5.
Additionally, when using VMware Workstation in an environment using Media Access Control (MAC) addresses as unique identifiers (UID), one should (and often must) manually configure the MAC address for each virtual machine in order to ensure uniqueness (for example, in an environment in which network switches implement MAC security; or in an environment in which Altiris products use the MAC address as the UID). In such a situation, disabling all networks/adapters other than "bridged" and editing each virtual machine's .vmx file to change "ethernet0.address" to a unique MAC and "ethernet0.addresstype" to "static" will help.

[edit] OS support

64-bit Solaris 10 1/06 (Update 1) and Solaris 10 6/06 (Update 2) fail with a triple fault on Core 2 generation processors (this includes processors codenamed Merom, Woodcrest, and Conroe). A Sun Microsystems blog has published a workaround for this issue.

[edit] Network protocols

VMware Workstation can swallow CPU interrupts, making maintenance of accurate time difficult.^[14] Network Time Protocol (NTP) servers should not be run under VMware.

[edit] Path traversal vulnerability

In February 2008, CoreSecurity.com discovered a vulnerability in the Shared Folders function within several VMware products, including Workstation. A user logged onto a guest VM running in VMware Workstation could gain read/write access to the host system by specifying a pathname with the ".." substring.^[15]^[16] However, the host is only vulnerable if the shared folders are turned on and at least one host folder is set for sharing. This vulnerability was fixed in VMware Workstation versions 5.5.6 and 6.0.3.
