by the guest firmware (BIOS/UEFI). If you require multiple disks for booting

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.
