Re: [ovirt-users] oVirt hook to manage physical CPU pool, and automatically pin CPUs without overlap on the host

Hi All Thanks for the help that people have recently provided on this list. I'm running into another edge case that, as far as I can see, does not have a native solution within oVirt. I have a use case where every VM must have 4 pinned vCPUs, and these must map 1:1 to physical CPUs so that there are never two VMs contending for the same physical cores. I already have code in place that ensures a VM will not be created or started if n/4 VMs are already running on the target host, where n is the number of physical cores. What I need now is to ensure that pinning is managed so that each physical core maps 1:1 to vCPUs. Would it be possible to manage the pool of physical cores in a local DB, and implement a VDSM hook similar to the example on this page? http://www.ovirt.org/VDSM-Hooks Or would there be a preferable solution?
