ubuntu_quota_smoke_test failed with KVM kernel

[Po-Hsu Lin]

According to Kamal's comment:
    CONFIG_QUOTA (and various other quota-related-looking configs) appear to be enabled already in the linux-kvm kernels -- but the required modules just end up in the regular linux-modules package (e.g. linux-modules-x.y.z-a.b-kvm)

However even with the linux-modules-x.y.z-a.b-kvm package installed, this test will still fail with KVM kernel.
