From b8865591d4d5680b4f766c25ca1db110320b4d15 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Fri, 31 Oct 2014 16:38:32 +0000 Subject: pc: kvm: check if KVM has free memory slots to avoid abort() When more memory devices are used than available KVM memory slots, QEMU crashes with: kvm_alloc_slot: no free slot available Aborted (core dumped) Fix this by checking that KVM has a free slot before attempting to map memory in guest address space.
