[Xen-devel] can hypervisor run on multi-core at the same time
Hi,
I found that there is a sharp decline on VM''s performance when a
number of VM runing on the same physical hostile, I think maybe xen hypervisor
is bottleneck, my question is can hypervisor run on multi-core at the same time.
thanks!

How are you measuring performance? The hypervisor can run simultaneously on every core of a multi-core system. It does have internal locking and synchronisation of course, but actually there¹s little contention when different VMs run on different cores. -- Keir On 19/10/08 09:24, "xdongp" <xdongp@gmail.com> wrote:> Hi, > I found that there is a sharp decline on VM''s performance when a number of > VM runing on the same physical hostile, I think maybe xen hypervisor is > bottleneck, my question is can hypervisor run on multi-core at the same time. > thanks! > > 2008-10-19 > > xdongp > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
