Maxing only Single core on instance with multiple vcpus
Hi all,
Just recently deployed Openstack Queens onto an Ubuntu 18.04 LTS Server. Followed the guide doc(s) on the Openstack website.
Note that this is an all-in-one build.
After running htop to see the systems overall usage, I can see that there is really only one core of my 4-Core ( 8 Threads ) processor is completely maxed at 100% while running instance(s) with all other cores remaining underutilized.
I tested this with running instances with 2, and then 4 vCPUs - Which shows a similar result in CPU usage.
I tried increasing the property cpu_allocation_ratio
in nova.conf
, but nothing changed.
Any ideas on what the issue might be? Could this be an openstack issue or something else that I need to rectify.
Thanks in advance.
