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

<br>
Or would there be a preferable solution?<br>
<br>
Thanks<br>
