host - Fedora 12 64bit
guests - Windows Server 2008, Ubuntu 9.10, Debian 5.0 and Fedora 12, all 64bit
The virtual machine is working.
Flash drive (USB) can be attached to all guests and are visible on them except Windows Server 2008. On host ping Windows Server 2008 works without problem. Windows Server 2008 ping host also works without problem
Please advise where to check and how to solve the problem. TIA
