After successfully completing the migration from vCenter 6.0 (on Windows) to the vCenter 6.5 Appliance, all I had remaining was to upgrade my ESXi hosts to ESXi 6.5.

In my test environment, I run 2 x HPe Proliant DL360p Gen8 servers. I also have always used the HPe customized ESXi image for installs and upgrades.

It was easy enough to download the customized HPe installation image from VMware’s website, I then loaded it in to VMware Update Manager on the vCenter appliance, created a baseline, and was prepared to upgrade the hosts.

I successfully upgraded one of my hosts without any issues, however after scanning on my second host, it reported the upgrade as incompatible and stated: “The upgrade contains the following set of conflicting VIBs: Mellanox_bootbank_net.XXXXversionnumbersXXXX. Remove the conflicting VIBs or use Image Builder to create a custom ISO.”

I checked the host to see if I was even using the Mellanox drivers, and thankfully I wasn’t and could safely remove them. If you are using the drivers that are causing the conflict, DO NOT REMOVE them as it could disconnect all network interfaces from your host. In my case, since they were not being used, uninstalling them would not effect the system.

I SSH’ed in to the host and ran the following commands:

esxcli software vib list | grep Mell (This shows the VIB package that the Mellanox driver is inside of. In my case, it returned “net-mst”)

esxcli network nic list (this command verifies which drivers you are using on your network interfaces on the host)

esxcli software vib remove -n net-mst (this command removes the VIB that contains the problematic driver)

After doing this, I restarted the host, scanned for upgrades, and successfully applied the new vCenter 6.5 ESXi Customized HPe image.

  1. […] A note on a problem I dealt with during ESXi 6.5 upgrade (conflicting VIBs marking image as incompatible when deploying HPe customized image) can be found here: […]

  2. Just went through this myself, thanks for the post! A few notes:

    The VIBs my esxi hosts complained about were different, but still not used, so I had to change the grep/remove commands to match

    The VIB remove commands take a loooong time on my boxes to execute, like 5+ min, and I thought they were stalled/doing something horrible. Nope, they just take a long ass time.

  3. Thank you! Same problem. Worked like a charm.

  4. Hi All,

    Need your help. I tried to upgrade our host Esxi 6.0.0, 3380124 to ESXi-6.5.0-20170104001-standard but got this error “The upgrade contains the following set of conflicting VIBs:” I am fully aware that I should delete if conflicting VIB but on this one it doesn’t display the conflicting Vib.


  5. Hi JC,

    Is this happening on one, or multiple hosts?

    If it’s one, maybe burn an ISO of the install image and try upgrading that way.

    Have you checked any other logs to see what package is causing the conflict?

    Out of curiosity, are you using a custom image, have you loaded any special VIBs or drivers on your install?


  6. Hi JC,

    My problem is a bit different, I wasn’t upgrading to a higher version of VM Ware vSphere, I was simply installing ESXi 6.5 on my first lab ESXi host as part of my VMware training, and got the following error:

    <CONFLICTING_VIBS_ERROR: Vibs on the host are conflicting with vibs in metadata. Remove conflicting vibs or use Image Builder to create a custom ISO providing newer versions of the conflicting vibs. ['Hewlett-Packard_bootbank_char-hpcrv_5.5.6.6-10EM-550.0.0.1198610'
    'Mellanox_bootbank_net-mst_2.0.0.0-10EM.550.0.0.600000', etc, etc

    Thanks for your help. Jorge

  7. Hi Jorge,

    It sounds like your install image is corrupt, or you’re maybe installing on to a previous install?

    I would recommend zero’ing the drive you are installing to, as well as re-downloading the ESXi installer images.


  8. In my case my error was:

    So i ran this command:
    esxcli software vib remove -n hio

    After confirming it wasnt being used. Thanks for the article.

  9. Hello I found your article very helpful. I had bootbank vib conflicts on HP DL360p G8s.

  10. Ever seen it went there were about 15 conflicting vibs? I am upgrading a different ESXI environment and one of my host has about 15 vibs conflicting.

  11. Hi Joe,

    That’s crazy. I’m curious what the conflicts are?

    Have you tried doing an upgrade using the install media (instead of vSphere Update Manager)?

    If that was me, I may just blow away the host and do a fresh install after trying to two methods above. For that to happen, it sounds like the host is either old, or has had quite a bit of work done to it while it’s been in production!


  12. I had this exact same problem and your solution fixed it. Thanks!
