Hi list !
I''ve one server running debian etch with Xen 3.2-1 and 3 w2k hvm vms.
Looking at xm top I see strange values for cpu(%) column:
xentop - 15:00:20 Xen 3.2-1
4 domains: 4 running, 0 blocked, 0 paused, 0 crashed, 0 dying, 0 shutdown
Mem: 16772032k total, 3446036k used, 13325996k free CPUs: 8 @ 2826MHz

Is normal the cpu usage goes above 100% or Am I misunderstanding something ?

Hi,> Looking at xm top I see strange values for cpu(%) column: > Is normal the cpu usage goes above 100% or Am I misunderstanding something ?100% is _one_ CPU with maximum load. Guess you have a multicore machine and assigned more than one processor to your VMs. Thomas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, it seems to be a sum or a calculation between the CAP and the weight of a domain by the credit sheduler. regards yves Alexandre Biancalana a écrit :> On 9/24/08, Dot Yet <dot.yet@gmail.com> wrote: > >> >> On Wed, Sep 24, 2008 at 4:45 PM, Thomas Karcher <thkarcher@gmx.de> wrote: >> >>> Hi, >>> >>> >>> >>>> Looking at xm top I see strange values for cpu(%) column: >>>> >>>> Is normal the cpu usage goes above 100% or Am I misunderstanding >>>> >> something ? >> >>> 100% is _one_ CPU with maximum load.
