Ack to the report.
While I had some systems (lpar) which worked I was trivially able to confirm that it doesn't work on KVM guests based on cloud images.

I see this on install of kdump-tools (default answers to debconf)
Setting up kdump-tools (1:1.6.4-2) ...
Using config file '/etc/zipl.conf'
Building bootmap in '/boot'
Adding IPL section 'ubuntu' (default)
Preparing boot device: vda (0000).
Done.

Creating config file /etc/default/kdump-tools with new version

But that leaves /etc/zipl.conf unmodified.
Frank already copied the snippet in the report.
This line isn't working:

$ sed -i "/parameters/{s|\"$| crashkernel=${DEF_PRESET}\"|}" /etc/zipl.conf

At least in my guest and my LPARs the following seemed better, so for your consideration:

$ sed -i "s/^parameters\s*=/& crashkernel=${DEF_PRESET} /" /etc/zipl.conf

Note: at this point it already checked there is no crashkernel statement yet, so we can unconditionally insert it here.
