Improve coordination between a Linux guest and its hypervisor.
Provide paravirtualized I/O, time synchronization, clean shutdown, and guest-information reporting appropriate to the platform.
What should be installed?
Platform-specific guest drivers and agents provide paravirtualized I/O and management integration. Install only trusted components required by the hypervisor.
Detailed explanation
Correct. Guest drivers and agents matched to the platform provide the requested integration.
Correct. Guest drivers and agents matched to the platform provide the requested integration.
Incorrect. A different distribution's bootloader does not provide hypervisor integration.

Try it yourself
An example you can run in a temporary verification environment.
systemd-detect-virt; lsmod | grep -E '^(virtio|hv_|vmw_)' | headExpected result
