Undocumented VCB config.js feature

Filed under: Howto, VCB, VMware
One of my customers wanted to use the default VCB framework but did not want to quiesce the VM for several reasons. (Databases, Active Directory etc.) I could not find an option in the config.js file but noticed the following in the file glue.js:
// A fallback to be able to switch to non-quiesced snapshots
if (typeof(NO_QUIESCE) != "undefined") {
cmd +="-Q 0 ";
}
In other words, setting the option “NO_QUIESCE” with no value in config.js results in the VM not being quiesced, default it will quiesce the VM! I added the following line to the config.js file to accomplish this:
NO_QUIESCE="";

I have accomplished this also in the past by showing the hidden devices within the VM, and disabling the Legato sync driver.

That’s also an option indeed… you can also chose not to install the sync driver.

[…] Duncan, a new and undocumented feature in VCB’s config.js file that allows for non-quiesced snapshots of virtual machines. I’d be interested in […]
