I used to experiment a bunch with GPU passthrough to VMs and also found that CPU pinning was required to avoid stutters. I always found it unfortunate as pinning works directly against what one tries to achieve with virtualization (i.e. sharing of resources).

I had never considered telecom suffering from the same issue. Do you know if there's been any work to improve scheduling to mitigate this requirement?

There are other issues at play, such as the need for SR-IOV support and sometimes direct mapping of PCI lanes to some workloads. There is only so much virtualization can do when you're letting millions of sessions through.
