testutil: Add HyperVSupported check

[dcantah]

Will probably be a growing amount of hyper-v tests, and they'll all need this preamble to check if virt/nested virt is turned on.

[AkihiroSuda]

Is this still a draft?

[dcantah]

Sorry for delay @AkihiroSuda, I think this is okay to un-draft. Will keep an eye on CI result, I'll need to look into the CI failure

[dcantah]

Figured out why this is failing -_-, there's a process isolated test that checks that the output of container inspect --mode native doesn't contain the string hyperv. However, the output of container inspect --mode native includes the environment variables for the oci hooks (although these don't do anything on windows) which seems to inherit the env vars of the host. Cirrus sets a bunch of environment variables with the commit and pr messages, where I've used, you guessed it, the string hyperv in my commit message.

"CIRRUS_COMMIT_MESSAGE=testutil: Add HyperVSupported check\n\nWill probably be a growing amount of hyperv tests, and they'll all need this preamble to check if virt/nested virt is turned on.\r\n\r\nDraft for now until I can run the suite on my windows box also. Been meaning to do this anyways",

The sooner this lands, the better for me. Thanks.

Been trying to find time, do you want to try and find a good testcase for the test(s) described above that check for the "hyperv" string? This should work after that, frankly this should work right now as is if I removed hyperv from my commit message 😭

[dcantah]

Perhaps we can check this in and I'll make an issue for us to fix the hyperv string check. CI should pass now that I changed hyperv to hyper-v

[dcantah]

Failures in the CI for 22.04 should be irrelevant

[dcantah]

I've made #2126 to track fixing the process isolated test

[dardelean]

Can this be merged? Would help me in #2145. Thanks.

[AkihiroSuda]

CI can't be restarted, could you rebase and push again?

[dcantah]

@AkihiroSuda Done

[AkihiroSuda]

Thanks
