Description:
At hxp, we LOVE VMs. Hope you too.
lkvm repo: git://git.kernel.org/pub/scm/linux/kernel/git/will/kvmtool.git
head is at 39181fc6429f4e9e71473284940e35857b42772a
Changes in lkvm: See lkvm.diff. One is a hardening and the
other one was a hack to fix an issue with input to the terminal.
Update: If you encounter Fatal: unable to create KVM VCPU thread (e.g. on some bigger AMD CPUs) while hosting the challenge locally, try increasing the PID limit (-lpid) in the Dockerfile.
