I am using a PC (AMD Ryzen) with Linux (Ubuntu 18.04, Kernel 5.5.19).
I want to activate the hypervisor "jailhouse" on this PC and start
another Linux on a CPU core without using KVM / QEMU.
I built and installed "jailhouse" from the GIT repository (as of
08/13/2020).
With "sudo jailhouse config create configs/x86/sysconfig.c" I created a
system configuration.
When "make" was called again, the "configs/x86/sysconfig.cell" file was
created.
The kernel module was loaded with "sudo insmod
/lib/modules/5.5.19-050519-generic/extra/driver/jailhouse.ko".
Unfortunately, when I call "sudo jailhouse enable
$HOME/Projects/Jailhouse/jailhouse.git/configs/x86/sysconfig.cell" I
only get the message "JAILHOUSE_ENABLE: Invalid argument".
What could be the cause?
No output on the UART console? Nothing in the kernel logs (dmesg)?
You can increase the verbosity of Jailhouse by setting
#define CONFIG_TRACE_ERROR 1
in include/jailhouse/config.h, see also
Documentation/hypervisor-configuration.md.
