Yes, you are right, load 30 with a 2 CPU VM is nearly impossible. In the past, there where a issue with a defect HD and a failing resync on glusterfs here in the list. - Take a look deeper look on your ovirt-node(s) -- Systemcalls with (seeing kernel und userspace syscalls): # perf top - IO with: # iotop - Processes with: # htop Ansible Script to install the tools: --- # # Install Additional Packages on Centos 7 machines # Possible Repos: base,updates,extras,centosplus # - hosts: - ovirt-nodes gather_facts: False tasks: - name: Install additional Packages yum: enablerepo: base name: - perf - iotop state: present - name: Install additional remote Packages yum: name: - https://kojipkgs.fedoraproject.org/packages/htop/2.2.0/1.el7/x86_64/htop-2.2... state: present ...

I'm wondering how I can best limit the ability of VMs to overrun the load on hosts. I have a fairly stock 4.2 HCI setup with three well spec'ed servers, 10Gbe/SSDs, plenty of ram and CPU with only a hand full of light use VMs. I notice when the occasional demanding job is run on a VM I'm seeing load average on host node shoot up in to the 20-30s, how can a single "medium" vm cause host load to rise so high?
