Description of problem:
Currently, our DPDK checkup VM as well as our reference DPDK-VM spec does not prescribe setting spec.domain.cpu.isolateEmulatorThread=true.

Running simple testpmd tests with no disk I/O you will not catch emulator threads or IOthreads isolation issues. However, real applications typically have a couple of threads that do regular I/O (e.g. writing logs to disk).

We should enable this attribute.
