Ah, I was assuming that some of the suite ran usefully as non-root given that the only point of that sudo was to acquire root. If the whole thing needs to be root then we should instead have a check for root at the top of run_vmtests.sh and just skip the whole thing if we aren't root, but then I'm unclear why it's invoking sudo in the first place.
I can't speak for how others use the suite, but there are a bunch of setup operations in the script itself that require root (e.g. reserving huge pages). Some of the tests will work without root, I'm sure, but I'm not sure its hugely valuable. Personally, I'd vote for just doing a test for root at the top, as you suggest.
The hugetlb tests appear to be checking for root while running... I'm not super fussed either way myself, I don't really use these tests myself except in a general "keeping an eye on CI" kind of way so I'd not object if people wanted to just go for just requiring root for the whole thing.
