From: Alexandru Avadanii Date: Fri, 21 Jul 2017 19:59:33 +0200 Subject: [PATCH] lib.sh: Use host-passthrough when spawning VMs virsh defaults to using "host-model" instead of "host-passthrough", which not only might lead to a small performance hit on x86, it is also causing compatibility issues with libvirt 3.x. Address this by explicitly requesting "host-passthrough" as the CPU model for virt-install.
