Chen Qi (1):
testimage: fix boolean checking for QEMU_USE_KVM

1.9.1

If QEMU_USE_KVM is set to a list of machines, when doing testimage for a machine outside the list, we will get the following error.

Exception: ValueError: Invalid boolean value 'intel-corei7-64 intel-core2-32 qemux86 qemux86-64'

This is because oe.types.boolean raises error if the parameter is not values like 'true', 'false', etc.

Fix the boolean checking to avoid the exception.

Personally, I think we should just drop support for listing the machines in QEMU_USE_KVM and suggest people use overrides instead?

Cheers,
