betty-release has been failing multiple tests for a little while here.

(These are informational tests, so failures hopefully don't cause any issues -- they shouldn't turn the stage red, for instance.)

Stephen and/or Jeff, is it expected that Crostini tests are running on betty (a board that's only run within a VM)? I was surprised to notice this earlier today. The DUT is reporting that it reports the vm_host feature:

2018/10/03 17:12:35 Software features supported by DUT: android autotest-capability:usb_camera chrome chrome_login cups selinux vm_host

That means that the kvm_host USE flag is set for betty. Is that intentional or accidental?

I haven't looked at the security.GPUSandboxed and ui.SupervisedUserCrashARC failures yet.

kvm_host was turned on for betty in crrev.com/i/675094

+lepton should this get turned off again?

Comment 3 by lepton@chromium.org, Oct 4 

I think actually it's possible to test crostini inside betty if host enabled nested kvm. Let me check if I can "fix" this by skipping tests when kvm is actually not working on betty.

Comment 4 by derat@chromium.org, Oct 4 

Please don't make the test report success if it doesn't actually run -- that's confusing when looking at results.

What specifically controls whether nested KVM is enabled? Do you plan to enable it for all of the builders?

Comment 5 by lepton@chromium.org, Oct 4 

Re #4, I will just skip them. won't report success. If all of our builders is intel. then it can be enabled by this:

echo options kvm_intel nested=1 | sudo tee -a /etc/modprobe.d/kvm.conf
#reboot

Skip VM tests on VM boards before we enable nested KVM on builders.
