SYSTEM REQUIREMENTS

Hardware
  • Minimum 1.66 GHz x86 (32-bit) or x64 (64-bit) CPU.
    • NOTE:To run 64-bit guest operating systems, you need a processor that supports the Intel VT-x or AMD-V hardware virtualization technology. To assign PCI Express (PCIe) devices directly to your virtual machines, you need a processor that supports the Intel VT-d or AMD-Vi technology.
  • At least 2 GB of RAM (4 GB recommended to run Windows 7)
    • NOTE:The host computer must have enough memory to use the host operating system and its programs plus the memory required for each additional operating system (and its programs) that you want to use simultaneously.
  • At least 350 MB of space available on the boot volume for Parallels Workstation installation.
  • 15 GB of available disk space for each virtual machine.
  • DVD-ROM drive.
  • Ethernet network adapter.
  • If you want to use a directly connected PCIe video card in your virtual machines, Parallels Workstation 6 Extreme officially supports the NVIDIA Quadro®FX 1800, 3800, 4800, 5800, Q4000, Q5000 video cards for virtual machines. For these video cards, use the latest drivers available on the manufacturer's website and NVIDIA Video BIOS version of 62.00.62.00.01 or later. If you have a supported video card which does not have this BIOS level, please contact your OEM supplier.

KNOWN ISSUES

  • After you installed Parallels Workstation Extreme on the Windows 7 (64-bit) host computer, you are unable to connect any USB device to the virtual machine. Reboot the host computer to resolve the issue.
  • The Mouse Synchronization, Dynamic Resolution, and Coherence tools are not available in the Windows 8 Developer Preview guest operating system after Parallels Tools are installed.
  • Sometimes sound recording may experience some lagging.
  • The Ubuntu 11.04 (64-bit) operating system may fail to start after it was migrated to a virtual machine using Parallels Transporter.
  • Sometimes the RHEL 6.1 (64-bit) operating system installed on the HP z800 host computer may hang while the Parallels problem report is being generated. Reboot the virtual machine to resolve the issue.
