Yes, If pmd-cpu-mask not specified, the pmd thread defaults to core 0. In case you want to explicitly pin pmd thread to core 3, pass pmd-cpu-mask=4. For more information check ovs-vswitchd.conf.db man pages.

You should be able to run 2 VMs on 4 core CPU. For better performance (core 0 - platform logic/ core 1 - VM1 qemu thread/ core 2 - VM2 qemu thread/ core 3 - pmd thread).
