This bug was fixed in the package qemu - 1:2.11+dfsg-1ubuntu6
---------------
qemu (1:2.11+dfsg-1ubuntu6) bionic; urgency=medium
* Remove LP: 1752026 changes to d/p/ubuntu/define-ubuntu-machine-types.patch.
The Kernel fixes are preferred and already committed to the kernel.
Therefore remove the default disabling of the HTM feature (LP: #1761175)
* d/p/ubuntu/lp1739665-SSE-AVX-AVX512-cpu-features.patch: Enable new
SSE/AVX/AVX512 cpu features (LP: #1739665)
* d/p/ubuntu/lp1740219-continuous-space-commpage.patch: make Arm
space+commpage continuous which avoids long startup times on
qemu-user-static (LP: #1740219)
* d/p/ubuntu/lp-1761372-*: provide pseries-bionic-2.11-sxxm type as
convenience with all meltdown/spectre workarounds enabled by default.
This is not the default type following upstream and x86 on that.
(LP: #1761372).
* d/p/ubuntu/lp-1704312-1-* provide means to manually handle filesystem-dax
with pmem by backporting align and unarmed options (LP: #1704312).
* d/p/ubuntu/lp-1762315-slirp-Add-domainname.patch: slirp: Add domainname
option to slirp's DHCP server (LP: #1762315)
