[Swan-dev] Workaround for: can't apply global Broadwell-noTSX-x86_64-cpu.spec-ctrl=on when testing

[Andrew Cagney]

It seems that there's a problem with testing on fedora (with current
packages) where an attempt to create a domain can die with:

  ERROR    internal error: process exited while connecting to monitor:
2018-02-14T17:48:28.610786Z qemu-system-x86_64: can't apply global
Broadwell-noTSX-x86_64-cpu.spec-ctrl=on: Property '.spec-ctrl' not
found

see https://bugzilla.redhat.com/show_bug.cgi?id=1545360

The workaround is to add:

  VIRT_INSTALL = sudo virt-install --connect $(KVM_CONNECTION) --cpu
host-passthrough

to Makefile.inc.local.
