I updated 2 Fedora 28 hosts today, getting new ovirt-master-release.rpm, which exposes new virt-preview repo providing libvirt 4.9 and qemu 3.1. After the update, connecting with engine master (built few week ago) fail with: 2018-11-26 22:07:51,702+02 WARN [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-94) [] Unexpected return value: Status [code=-32603, message=Internal JSON-RPC error: {'reason': "[Errno 2] No such file or directory: '/usr/share/libvirt/cpu_map.xml'"}] Looks like contents of /usr/share/libvirt/ is different now: $ ls -1 /usr/share/libvirt/cpu_map/*.xml | head /usr/share/libvirt/cpu_map/index.xml /usr/share/libvirt/cpu_map/ppc64_POWER6.xml /usr/share/libvirt/cpu_map/ppc64_POWER7.xml /usr/share/libvirt/cpu_map/ppc64_POWER8.xml /usr/share/libvirt/cpu_map/ppc64_POWER9.xml /usr/share/libvirt/cpu_map/ppc64_POWERPC_e5500.xml /usr/share/libvirt/cpu_map/ppc64_POWERPC_e6500.xml /usr/share/libvirt/cpu_map/ppc64_vendors.xml /usr/share/libvirt/cpu_map/x86_486.xml /usr/share/libvirt/cpu_map/x86_athlon.xml Do we have a fix for this?
