|Subject:||[Qemu-discuss] Latency degradation on VM due to several QEMU processes on the host.|
|Date:||Sun, 19 Jun 2016 11:38:59 +0000|
Can you please comment on the overhead QEMU brings in terms of latency and CPU utilization?
I am running a highly latency sensitive application on my VMs and I see some degradation in performance when running 2 QEMU processes on a single core, or even when I run 1 QEMU process on a single core without a dedicated affinity and RT priority to the QEMU process.
Can I make the QEMU lighter to be able to run 2,3 or more QEMUs on a single core? Is it matter of XML configuration / affinity / priority or anything else?
