Some more nuggets about handling VIB files

· ·

After I posted my article yesterday Jason Boche posted a comment about the reboot that was required according to the screenshot. I looked in to it and quickly realized that if I would alter my “descriptor.xml” I would not get this message. In other words, it depends on the package that is installed if a reboot is required or not, in my case I made the following simple changes to install the package without the need to reboot:

<live-install-allowed>true</live-install-allowed>
<live-remove-allowed>true</live-remove-allowed>

In other words, I am allowed to install it without a reboot and remove it without a reboot. Simple huh? Of course I tested it and this is the result:

~ # esxcli software vib install -v /test.vib
Installation Result
   Message: Operation finished successfully.
   Reboot Required: false
   VIBs Installed: Duncan_bootbank_firewallrule_1.0
   VIBs Removed:
   VIBs Skipped:
~ #

After clicking refresh in the vCenter client the firewall rule I created pops up as expected.

Now if you would like to know before installing what the package contains and what the requirements are you can simply figure that out by doing the following:

~ # esxcli software sources vib get -v file:/test.vib
Duncan_bootbank_firewallrule_1.0
   Name: firewallrule
   Version: 1.0
   Type: bootbank
   Vendor: Duncan
   Acceptance Level: CommunitySupported
   Summary: Firewall rule
   Description: Firewall rule
   Release Date: 2011-06-01
   Depends:
   Conflicts:
   Replaces:
   Provides:
   Maintenance Mode Required: False
   Hardware Platforms Required:
   Live Install Allowed: True
   Live Remove Allowed: True
   Stateless Ready: False
   Overlay: False
   Tags: driver, module
   Payloads: test
~ #

As you can see in this case, “live install allowed” is set to true. The vendor is “Duncan” and the Acceptance Level is “CommunitySupported”, these are important details in my opinion! Another one to keep an eye on is if the package is “Stateless Ready” or not. In my case I defined it as “false”.

Of course you can also remove a VIB file after installing it. This is pretty straight forward, first of all list all the installed VIBs:

~ # esxcli software vib list
Name                  Version                             Vendor  Acceptance Level  Install Date
--------------------  ----------------------------------  ------  ----------------  ------------
ata-pata-amd          0.3.10-3vmw.500.0.0.456551          VMware  VMwareCertified   2011-06-06
ata-pata-atiixp       0.4.6-3vmw.500.0.0.456551           VMware  VMwareCertified   2011-06-06
ata-pata-cmd64x       0.2.5-3vmw.500.0.0.456551           VMware  VMwareCertified   2011-06-06

After listing all installed VIBs you can easily remove them by using the following command:

~ # esxcli software vib remove -n ata-pata-amd

This would remove the VIB named “ata-pata-amd”. You could even do a “dry-run” to see what the result would be:

~ # esxcli software vib remove -n ata-pata-amd --dry-run
Removal Result
   Message: Dryrun only, host not changed. The following installers 
   will be applied: [BootBankInstaller]
   Reboot Required: true
   VIBs Installed:
   VIBs Removed: VMware_bootbank_ata-pata-amd_0.3.10-3vmw.500.0.0.456551
   VIBs Skipped:
~ #

I hope this provides some more details around how to handle VIB files. Don’t hesitate to leave a comment if you have any questions at all.
