Thank you Jan for pointing out the old NUC will work.
For my application, newest processor might not necessary.
This might be good enough for me (if the NUC is still easily available.)

Are there any officially tested x86-64 based SBC or mini PC?

Hi,
I am working to get jailhouse work with my R-Pi4.
I have been using a 64bit Debian buster rootfs with
a custom compiled 5.9 preempt-rt kernel.
I have successful reserved >736M for jailhouse and inserted the
jailhouse.ko, but when I do jailhouse enable I got the following error on
uart.
Hi,
I want to ask a silly question.
Is there any restrictions on the cell configs source files, including those
hand crafted and these generated by jailhouse command line tool ?
For a hand crafted configs, may I distributed them with the licenses as I
wish?
On the other hand for generated

Hi,
I am upgrading from v9.1 to most recent version of Jailhouse recently.
As the ivshmem version has changed, the old drivers and way of doing no
longer works.
I am curious should I cherry-pick the commits on the jailhouse-linux git to
my kernel source?

I also noticed this.
I am working on a Broadwell machine with 2.2Ghz of core frequency.
Jailhouse get set the cpu_khz in comm region with the frequency probed by
Linux during boot.
I got somthing like ~2.1997Ghz in that field.
The difference is so small that I don't have a good way to evaluate

I measured using an oscillate scope and function generator.
I am using MMIO GPIOs. The application calls a system call and waits for an

I will summarize first, the fault seems like to be in the wip/ivshmem2.

Let me describe my setup first.

I do think there are contentions related to memory, either TLB or

I will check if they fit.

Alright, I have test the latency from HW IRQ to application response.
I found out that there aren't any additional VM-Exit or IRQ, nor RTOS
scheduling and house-keeping.
It feels like the processor is generally slower as everything takes longer
to run.
The IRQ epilogue takes ~7.8us and iretq

Hello,
I am looking for some help.
I am using ivshmem-v2 with virtio.
I am planning to implement a virtual serial driver on top of it.
I ripped off the ivshmem-net driver, and obtain a queue which I should able to
communicate with other cells from host.
The problem is that during root cell's

Hi,
I had previously posted question on the power management(PM) on x86.
I would like to share some of my discoveries and discuss this strange
phenomenon.
In the previous discussion, I was acknowledge that newly created cells are
running in full power. They have to manage the power themselves.

I regenerated the config and cross checked with the working one.
Nothing vicious was found.

I am working on ivshmem-net to achieve communication between host and cell.
Therefore, I applied the ivshmem2 patch both on the jailhouse and root-cell

address without problem. The non-root

I am using jailhouse to run a RTOS(nuttx) on a Xeon E5-2630 v4 machine.
I am currently trying to implement interrupt driven seril output. Therefore, I
tried to remap the IRQ4, which is the ttyS0's IRQ, to the RTOS.
I try to mimic IOAPIC demo's procedure of reampping ACPI IRQ to remap
