Are you still working on this? I'm trying your patches and it seems I had a simple issue: EJ0 is sent, guest ack's and removes the CPU, but it get's stuck somewhere between the BIOS and Qemu. CPU is successfully removed from the guest, but it still appears on QOM: (qemu) info cpus * CPU #0: pc=3D0xffffffff8104f596 (halted) thread_id=3D22208 CPU #1: pc=3D0xffffffff8104f596 (halted) thread_id=3D22209 CPU #2: pc=3D0xffffffff810429c8 (halted) thread_id=3D22281 (qemu) info qom-tree=20 /machine (pc-i440fx-2.1-machine) /fw_cfg (fw_cfg_io) /fwcfg[0] (qemu:memory-region) =20 [...] =20 /cpu3 (SandyBridge-x86_64-cpu) =20 [...] Do you have any clues? --=20 Eduardo Otubo ProfitBricks GmbH --DocE+STaALJfprDB Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBAgAGBQJXaoDAAAoJEP0M/1sS+L0vLm0H/3c/B5FEDgI1i7aqZeWBBDVZ u8IH/1HcOjDd59+vs1sxJeKZpZHA6pwBiQhzGTee+iC5gGGDNTrgy0vBLenMXoM+ /2Ww6NJlEUePYIoTlHigqXiG++njvhQhwhvr1ZEMkggFBEqSoyCkjndwssxcowA1 uR4vP7ZNHzu1iKyBwJH0yHlOMx2tqSax5nfHfD2h0Qt7voaGZe+p0y3o7l/RPiZB 5NUgeCmb6cnyR7C0nons/vvgtBdv6wmsHasHY1/u4W84lnSRV76AY/fUhSc+mSvg kIZGDK1WYi9XvFkCnr9rpaZ1occDJLq2Vjgfv++JZVB+TNWkLAF+rWPtI7J7kfY= =B61E -----END PGP SIGNATURE----- --DocE+STaALJfprDB--
