I've attached my .config.

I start the vm using:

./vm sandbox --rng --balloon -k /usr/src/linux/arch/x86/boot/bzImage -d run -d /dev/shm/swap --no-dhcp -m 3072 -c 6 -p
"init=/virt/init zcache ftrace_dump_on_oops debugpat kvm.mmu_audit=1 memblock=debug slub_debug=FZPU" -- /runtrin.sh

Where /runtrin.sh inside the vm simply mounts some stuff like sysfs and proc,
creates the swap space and runs trinity.


Thanks,
Sasha
