Fusion 3.1.4 works with Mac OS x Lion

5.5: web.cyb/mac#lion/fusion ok with upgrade?:
6.11: summary:
. I updated to latest the Fusion 3.1.4
before doing the upgrade to Lion,
and everything turned out great;
the usb camera works fine,
and other usb devices are used only from
the host OS (mac).
. I did not need to uninstall and reinstall Fusion .
. I already had the recommended 4gb ram .
. I did not intend on using mac as a guest OS
( if that idea appeals to you,
then you'll want the upgrade to Fusion 4.0 ).

VMware Fusion 3.1.3 is 10.7 (Lion)-compatible with some limitations.
. designed for OS X 10.5 (Leopard)
and OS X 10.6 (Snow Leopard).
. if you choose to upgrade to Lion,
VMware can provide best-efforts support
but cannot guarantee a resolution for all issues.

. running an older version of VMware Fusion?
upgrade to VMware Fusion 3.1.3
before upgrading to Lion.
For the best experience,
reinstall Fusion after upgrading to Lion.

    Minor visual issues have been reported
    when using Mission Control with Unity mode.
    Mac OS X 10.7 (Lion) Client and Server
cannot be run as guests.

    The minimum RAM requirement for Lion itself
is 2GB of RAM.
VMware recommends upgrading to
at least 4GB of RAM.

USB devices fail after
upgrading to Mac OS X Lion (10.7) (2004687).

These are due to incorrect filesystem permissions on the Mac.
After upgrading to Mac OS X Lion (10.7):
    You cannot use USB devices in the virtual machine
    USB devices do not work in your guest
    The system.log file contains the error:
    Can't create kext cache under / - owner not root.
This issue occurs when, after upgrading
from Snow Leopard (10.6) to Lion (10.7),
the permissions on the root directory of the host (/)
are incorrect.
To verify the current permissions on the root ( /):
    enter this in Terminal.app:
ls -ld /
    The command output should look similar to:
    drwxr-xr-x 53 root wheel 1870 Aug 10 12:43
The date and the other numbers may be different.
The most important parts are the
first string of letters and dashes (drwxr-xr-x),
and names of owner and  group (root wheel).
To correct the permissions:
    Quit Fusion.
    In Terminal, run this command:
    sudo -s
    chown root:wheel /
    chmod 755 /
Restart your Mac.
Fusion can now detect and use USB devices.
vmware is supported by lion,
but some are having problems:

i can't seem to get Fusion 3.1.3 working.
I uninstalled, rebooted, reinstalled, rebooted, no joy.
Then found an article on adding kexts
in that may not have installed correctly.
Still no joy. I would love to hear
what other folks have tried that worked.

Aside from having to re-activate Windows 7/32 bit
- all seems just fine.
Also tried Windows 2003 Server R2 - worked fine as well
  Was on 10.6.8 with VMware Fusion 3.1.3.
Did this early 2011 15" MBP upgrade via App store
and it is fine. Didn't update other macs to Lion yet..

I'm having a problem with latest Fusion on Lion
and VM's with bridged network.
Haven't yet fully troubleshooted but it seems that
after some time the XP VM can no longer access the LAN.
Ping to and from the host (Lion) works fine.
Anyone here seen something simular?

I am running VMware Fusion 3.1.3 on a clean install of Lion
and have not had any issues so far.
Am running Windows XP, Windows 7,
Windows Server 2003/2008/2008 R2 VMs ok
(all created prior to Lion).
Note, I have a multi-monitor setup
and run VMs fullscreen
and always 'shut down' VMs (rather than suspending them)
so my usage may not be typical.

VMware Fusion (for Intel-based Macs)
Download including only VMware Fusion software

how to uninstall Fusion 3.x and earlier:
Note: In Lion,
the Library folder is hidden by default.
. in Finder's Go menu, be holding the Option key;
[ie, with the go menu open,
the option key toggles the library menu item .]
Run the uninstall script
called Uninstall VMware Fusion,
located in:
[Macintosh HD]/Library/Application Support
/Vmware Fusion/ .
Click OK when the uninstaller finishes.
Delete these folders or files:
       [Macintosh HD]/Library/Application Support
/VMware Fusion
        [Macintosh HD]/Users/
        [Macintosh HD]/Users/
/Library/Preferences/VMware Fusion
        [Macintosh HD]/Users/
/Library/Application Support/VMware Fusion
Restart the Mac.
This ensures all Fusion kernel extensions
are unloaded from memory.
This process does not affect
any of the existing virtual machines.
