The Current Performance Of Virgl3D, Future Plans

Are you talking about Crouton? Because from what I understand, it's more of a chroot type of deal.

No, I think the remark was about Crostini.

Performance-wise, looking at the chart in the article, I'd say 1/3rd of bare-metal sounds about right.

Actually, the 1/3 in the chart is for vtest, which is a test environment that doesn't use Qemu, but renders using the host driver and then it does a readback, pipes the data to the "guest" and does a software blit. This works pretty well for Kabylake, is very good for running the CTS, and completely tanks on Evergreen. The second column contains the relevant results for running in Qemu, there in the linked email the experiments with Evergreen show 1/6th of bare metal for the Unigine benchmarks.
