Because of the microcode update to Haswell/Broadwell CPUs, existing
domains using these CPUs may fail to start even though they used to run
just fine. To help users solve this issue we try to suggest switching to
-noTSX variant of the CPU model:
virsh # start cd
error: Failed to start domain cd
error: unsupported configuration: guest and host CPU are not
compatible: Host CPU does not provide required features: rtm, hle;
try using 'Haswell-noTSX' CPU model

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
