Consequences of disabling vtrnd

If this is not the appropriate place, I apologize.

Installing on an instance on vultr.com from booting from the standard image hangs. This is pretty well documented, and the equally well documented workaround is disabling vtrnd.

But are there lingering consequences from setting hint.vtrnd.disabled in the boot menu? The man page says virtio_random supplies the guest with high-quality random bits from the host. With this disabled, is the guest's entropy pool populated from a different high quality source or does the workaround leave the guest with only low entropy sources?

Thanks for any reply,
