[opensuse-arm] CPU1: failed to come online
Hello, I am running Leap 42.2 on Raspberry Pi 3 and trying to user qemu-kvm for OBS worker. Currently, I can not run guests with more that single CPU. Both using libvirt and using obsworker, I see 'CPU1: failed to come online'. [ 28s] booting kvm...

Hi Matwey, The QEMU code in 42.2 has a bug on rpi3 which prohibits it from running SMP guests. Can you please try to use the 42.3 kernel and QEMU? The following patch did make SMP work for me: https://github.com/openSUSE/qemu/commit/3227a2bdc7a494194a6a4f7d5653ff178ecb... and that one is in 42.3. Alex On 21.06.17 11:43, Matwey V.

It is, but that's an older version of the patch. There we're missing the iothread lock, so internal state gets corrupted. Also IIRC there were some kernel side fixes for SMP support.

Cool, thank you. I will look into 42.3 soon. -- With best regards, Matwey V. Kornilov http://blog.matwey.name xmpp://0x2207@jabber.ru -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
