I'm trying to save a crashdump on a DellFC630 with 128G of RAM,
running Ubuntu 14.10, kernel 3.16.0-23-generic; used to host a bunch
of KVM-style VMs.

Since saving the full dump is taking forever & a day, I'm looking to
save a partial dump -- maybe a few addr space regions only from the
kernel VAS.

Is this even possible ? Any other options ? Or am I missing something here ?
