Subject: [PATCH 1/4] kvm tool: Stop init if check_extensions failed
Date: Fri, 10 Feb 2012 17:55:33 +0800	[thread overview]
Message-ID: <1328867736-4394-1-git-send-email-hamo.by@gmail.com> (raw)

If kvm__check_extensions found that some of the required
KVM extention is not supported by OS, we should stop the
init and free all allocated resources.
