Hi Mike,

I added
`dom0_vcpus_pin` to the boot line and `cpus = "all,^0-3"` to the domU configs

That didn't solve it.  One of the first commands that I try to execute in one
domU, which causes activity in the other domU, triggers a reboot.  As if the
change increased the likeliness of the event.

Could it be possible that it's not the activity on the DomU that is triggering the reboot, but rather network activity between two DomUs? If the cause were activity by itself on one DomU (or both DomUs), then it should be possible to trigger the reboot by causing activity on the DomU itself (or on both DomUs), without network activity.

What CPU architecture is your system based on?

Best regards,

Paul
