You can us the 'lspci' command to list existing PCI devices.

The type of mediated device to use.
cloud-init: Sets DNS server IP address for a container. Create will automatically use the setting from the host if neither searchdomain nor nameserver are set.

Network Card Model. The 'virtio' model provides the best performance with very low CPU overhead. If your guest does not support this driver, it is usually best to use 'e1000'.

Number of packet queues to be used on the device.
Allow reboot. If set to '0' the VM exit on reboot.

+
+The file on the host to gather entropy from. In most cases /dev/urandom should be preferred over /dev/random to avoid entropy-starvation issues on the host. Using urandom does *not* decrease security in any meaningful way, as it's still seeded from real entropy, and the bytes provided will most likely be mixed with real entropy on the guest as well. /dev/hwrng can be used to pass through a hardware RNG from the host.
