I add more info about my error. Linux is the host OS, which runs a VM (i.e., QEMU/KVM VM) with a jailhouse image. Below, I represented the sequence of operations and outputs. *Linux: *./start-qemu.sh x86 *QEMU/KVM VM: *Jailhouse enable /etc/jailhouse/qemux96.cell *QEMU/KVM VM: *JAILHOUSE ENABLE: input/output error *Linux:* Initializing Jailhouse hypervisor v0.12 (342-gd6e64f90) on CPU 0 Code location: 0xfffffffff0000050 Using x2APIC.
