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 ? -- Rolland _______________________________________________ Kernelnewbies mailing list Kernelnewbies at kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
