+100% Host CPU usage while guest idling
+
+Hi,
+
+We have an appliance that runs a FreeBSD guest on a Yocto-based host via qemu-system-x86_64.
+Everything functions fine however the host uses n00% of the CPU (where n = #smp) and RAM allocated to it whilst the 1 guest is sat nearing idle.
+
+Host:
+PID     USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

+
+I have logged this with the appliance vendor and received the response:
+"This is expected behaviour and you will see the same in any case where a Guest OS runs over a Host OS.
+Host here has 5 CPUs and it has assigned all of them to Guest. 
+Since the Host is not being shared by any Guest OS; you will always see the 500% (or the 5 CPUs) given to qemu-system-x86.
+I do see the same in lab and is very much expected"
+
+This feels fundamentally wrong to me.
+I'm somewhat limited by what can be tested due to the nature of this being an appliance rather than a mainstream distro.
+
+I'm looking for feedback that I can use to push the vendor into investigating this issue.
+
+Versions below.
+
+Many thanks,
+Gareth
