[Openstack] KVM shows several processes for a single VM on the host

Hi Chris,
They appear to be processes when I see it in htop. I have attached the screenshot of a VM named "instance-000001bf" that has 4 virtual cores. In total, I can see 6 processes for the above referred VM.

Can I know is there a way to differentiate between processes and threads?
Best regards,
Krishnaprasad

Are they separate processes or separate threads? Separate threads would be expected, but separate processes would not be.
