Скачать или смотреть Arm and QEMU cpu models - where are we right now? by Cornelia Huck & Sebastian Ott

We previously talked about Arm cpu models at KVM Forum 2023, so now it is a good time to summarize the progress we have made so far, where thought is still needed, and how we can continue.

We will demonstrate examples of what is already working (and what is not) with the code available as of today, where the main gaps and points of contention are, and what could be possible directions: how the QEMU command line should be modeled, how the needs of management software such as libvirt could be met, and which combinations of systems are actually reasonable to focus on.

Join this talk to hear about guests being moved between different machines, fun with debug registers and other hard to virtualize registers, and how we can try to make Arm not completely different from x86.
