I tested this recently, my 6 year old Dell runs Ubuntu 2022 and has 16G RAM and nVidia with 4G VRAM. It runs a 2G VM running Ubuntu 2022 running Apache, Dovecot, postfix, MySQL and Postgres, for multiple domains. The host also runs all of those for local email.
Both the VM and the host runs Docker and containers. The host also runs k3s (Kubernetes single cluster) continuously for me to do various container running comparisons vs plain Docker.
With me logged in watching Netflix in a browser full screen it gets around 1.5 - 1.75 hours.
I guess if I were to just stream full screen without the VM running it'd run somewhat longer.
