Subject: [Qemu-devel] scheduling of qemu threads
Date: Thu, 31 Jul 2008 09:50:00 -0600 [thread overview]
Message-ID: <4891DF28.6040908@cisco.com> (raw)
Last week or so Anthony made a comment about qemu basically being single
threaded given its global mutex. What are the impacts to simultaneous
scheduling of qemu threads? As I understand it, qemu has a main thread,
a monitor thread, an IO thread and a thread for each vcpu. Can 2 or more
vcpu threads run concurrently? Can a vcpu thread and an IO thread run
concurrently? Does kvm alter the concurrency?
