This bug was fixed in the package qemu - 1:2.11+dfsg-1ubuntu2
---------------
qemu (1:2.11+dfsg-1ubuntu2) bionic; urgency=medium
* d/p/ubuntu/qemu-stable-2.11.1.patch: add stable release
- among other fixes this adds code to:
- mitigate the Spectre/Meltdown attacks (LP: #1744882) (CVE-2017-5715)
However, enabling this functionality requires additional configuration
beyond just updating QEMU. Also migrations need special consideration.
Details about that can be found at:
https://www.qemu.org/2018/02/14/qemu-2-11-1-and-spectre-update/
- Power9 allocation of max 8 threads per core (LP: #1750526)
* Drop changes that are part of the upstream stable release
- d/p/ubuntu/linux-headers-update-to-4.15-rc1.patch
- d/p/ubuntu/linux-headers-update-4.15-rc9.patch
- d/p/ubuntu/lp1743560-s390x-kvm-Handle-bpb-feature.patch
- d/p/ubuntu/lp1743560-s390x-kvm-provide-stfle.81.patch
* d/p/ubuntu/define-ubuntu-machine-types.patch: refresh to match stable update
* d/p/ubuntu/pre-bionic-256k-ipxe-efi-roms.patch: unify to only change the
common compat.h header and add some extra info in the patch header.
