Subject: bifrost: Set vCPU model to 'host-passthrough'
X-Git-Tag: 6.0.0~203^2
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=00617d7f8b9b6eeb0271c64b5fa04522ee0ef21b;p=releng-xci.git

bifrost: Set vCPU model to 'host-passthrough'

The default CPU model of QEMU GenuineIntel/QEMU Virtual CPU is not the
best option for vCPU in terms of performance. As such, lets use the
real host CPU. This has also been submitted upstream and the template
should be removed once the upstream patch has been merged and the SHA
for bifrost is bumped.
