CONFIG_KVM_GUEST is enabled: CONFIG_KVM_GUEST=y Yep, it's an old kernel. It's used as a testbed for throughput performance, that's how we noticed it was broken with the 4.14 host. However, I then discovered that a third-party router VM based on the 4.9 (IIRC) kernel behaved in a similar manner. Thanks, Tim
