No issues were observed. Guest domain 'reboot/destroy'use-cases work properly. Patch series was only build-tested on x86. Please note, build-test passed for the following modes: 1. x86: CONFIG_HVM=y / CONFIG_IOREQ_SERVER=y (default) 2. x86: #CONFIG_HVM is not set / #CONFIG_IOREQ_SERVER is not set 3. Arm64: CONFIG_HVM=y / CONFIG_IOREQ_SERVER=y 4. Arm64: CONFIG_HVM=y / #CONFIG_IOREQ_SERVER is not set (default) 5. Arm32: CONFIG_HVM=y / CONFIG_IOREQ_SERVER=y 6. Arm32: CONFIG_HVM=y / #CONFIG_IOREQ_SERVER is not set (default)I thought I woudl give a try to test the code, but I can't find a way to enable CONFIG_IOREQ_SERVER from the UI.Looking at the Kconfig, it looks like CONFIG_IOREQ_SERVER doesn't have a prompt and is not selected by Arm.Can you provide details how this can be built on Arm?Please apply the attached patch to select IOREQ on Arm. This is roughly what I wrote. I think a user should be able to select IOREQ via the menuconfig without any additional patch on top of your series. Can you include a patch that would enable that?
