VMware ESX

How to solve the VMware “PCI to PCI bridge detected” install loop

Have you ever P2Ved a server to an ESX cluster or converted a VMware Workstation VM into a VMware ESX 3.5 or vSphere 4.0 VM and come across this horrible Found New Hardware message that won’t go away.  Here’s a screenshot of a Windows 2000 Advanced Server that I had to fix and P2V after a catastrophic disaster (RAID failure) displaying this message:

Yes, it’s annoying and it seems like it will never go away.  You keep click on install and it keeps detecting after sucessfully installing as if it’s in a loop.  But the reality of it is that it’s not in a loop.  As silly as it sounds, you have to install it 32 times and it will finally go away! 🙂

The reason for this is because when you update the VM’s virtual hardware (specifically version 7 VMs from my experience), it comes with 32 separate PCI-to-PCI bridge devices that Windows detects and wants to install.  The only workaround I have found so far is to just sit there and install all 32 manually.  Or you can try editing your VMX and set:

pciBridge.present = False

which should work though I’ve never tried it personally.  Don’t want to potentially break something when it takes all of 2 minutes to install all 32 bridges.  Give it a shot and let me know if that fixes it for you guys. 🙂

    When the found new hardware wizard asks to go on the web, click no, and save your self some time.

    I had the same problem with a Win 98 virtual machine I converted from MS Virtual PC. The 32 click option was the only way to get it work under VMWare.

    Your suggestion of going through all the installs worked on a Win 98SE install I just did (for a lark). Thank you.

    This is what I did with a VM Workstation running Windows XP
    When the first box pops up DO NOT click anything, wait, open a command prompt and do this:
    cd \windows\inf
    del infcache.1

    now go back to hardware window and click no no internet and finish going through process, then reboot. Fix it for me

    Thanks a lot, yes it was worth the few mins rather than breaking a working server trying different options.
