This morning I needed perform several OVF uploads using ovftool and provide that information to engineering to investigate some performance issues. I tend to error on the side of providing more information than requested. The ovftool provides some really useful debugging options that are really handy in these situations but are un-documented. I can never seem to remember the exact syntax and hence I am documenting them here. I will also file a documentation bug to ensure these get added 🙂
UPDATE (08/19/13) - Thanks to one of the OVF engineers, it turns out you can see all the debug options and their definitions by running ovftool --help debug
The two options that I am referring to are:
The first option allows you to log the entire ovftool session to a file which you can then send off to someone and the second option allows you to control the verbosity of the logs which I normally set to use verbose.
Here is an example of how you would use these ovftool options:
/Applications/VMware\ OVF\ Tool/ovftool --X:logFile=upload.log --X:logLevel=verbose -ds=mini-local-datastore-2 '--net:Network 1=VM Network' VMware-vCenter-Server-Appliance-126.96.36.19900-1235310_OVF10.ova vi://[email protected]
Once the ovftool has completed its operation, you can take a look at the log and you will see quite a bit of information including some additional ovftool options that can be specified on the command-line which start with /X:
--> /X:httpTimeout = "0"
--> /X:imageReadSize = "262144"
--> /X:logFile = "upload.log"
--> /X:logLevel = "verbose"
--> /X:maxNumberOfTermSignals = "5"
--> /X:maxRedirects = "256"
--> /X:maximalDeltaConfSize = "8"
--> /X:maximalDeltaTreeSize = "6"
--> /X:progressSmoothing = "60"
--> /X:useMacNaming = "true"
--> /X:vCloudEnableGuestCustomization = "false"
--> /X:vCloudKeepTemplate = "true"
--> /X:vCloudTimeout = "3600"
--> /X:vimSessionTimeout = "600"
Note: I would not recommend tweaking the other options as the defaults should be sufficient, but logging to a file or upping the verbosity can be useful for troubleshooting
