SYMPTOMS
In Microsoft Virtual Server 2005 R2 Service Pack 1 (SP1), assume that a virtual machine is running a Linux guest operating system. However, the Administration Web site for Virtual Server displays the Guest operating system status as Unknown Linux instead of as Linux  as expected.

Note The  placeholder represents the version number of the Linux kernel.



CAUSE
This problem occurs because Virtual Server does not correctly recognize the version of the Linux kernel.
