I tried uninstalling both the VPN client and Parallels, then reinstalling and everything worked until I rebooted. So, that wasn’t going to work. After doing a ton of digging around, I found this post that suggested a fix that works!

Bring up a terminal and execute an ifconfig -a:

$ ifconfig -a

Find the interface that starts with “fw”. In my case, mine is called “fw0″. Next, shut off the interface:

$ sudo ifconfig fw0 down

fw0′s flags will now be 8822 and now the Cisco VPN client should work!

But what happens if you reboot? Oops! The fw0 interface comes back on. Disable the interface when the Cisco VPN subsystem is started:

$ sudo pico /System/Library/StartupItems/CiscoVPN/CiscoVPN

Then change the StartService() function to look like this:

StartService ()
{
    #disable fw0
    /sbin/ifconfig fw0 down

    if [ -d $CISCO_VPN_DIR ]; then
        ConsoleMessage "Starting Cisco Systems VPN Driver"
        kextload $CISCO_VPN_DIR
    fi
}

Test with a quick reboot and everything should work!

They claim that 3D graphics are supported now, so you can run your favorite Windows games. I assume that you can run other 3D applications such as Autodesk Inventor or 3D Studio Max. I am curious if 3D acceleration is supported for Linux VMs.

I’ve already pre-ordered my upgrade. If you have a Intel-based Mac, you should seriously consider giving Parallels a try.

I have a Macbook Pro and I use Parallels Desktop for Mac as my VM software. Installing previous Ubuntu releases was a piece of cake, but Ubuntu 7.04 was being a little “feisty” to install.

After trying the DVD, Desktop, and Alternative versions, I still had no luck. It was hard to tell what the problem was on the DVD and Desktop editions since they were live CDs and the screen just went blank. The Alternative version gave me a clue that the installer couldn’t load the CD/DVD drivers.

After doing some digging, I discovered there is a problem with both Parallels CD/DVD driver and the latest Linux kernel that ships with 7.04.

To get around the problem, I changed the OS Type to “Solaris” and OS Version to “Other Solaris” and then tried again to install Ubuntu.

Ubuntu’s installer found the drive without a problem and successfully installed the operating system. After the installation was complete, I shutdown the VM and changed the OS Type back to “Linux” and OS Version to “Other Linux kernel 2.6″. I have no idea if the CD/DVD drive works after changing these back, nor do I know if there are any issues with just leaving the OS Type as Solaris.

My hopes are that either a new kernel and/or Parallels releases an update to fix this problem. Honestly though, I have never used the CD/DVD drive in a Linux VM since everything I install is downloaded.

Has anybody else had this issue or come up with a better workaround?
