Hi Everyone, Given the "arms length" seperation between Dom0 and DomU, how is SolusVM able to provide stats on disk usage and RAM usage? Does SolusVM run some daemon on each DomU to collect these stats? Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi, I am not sure how SolusVM gets its statistics - however it is possible to get data from within domUs via VM introspection. Take a look at the xen-access library etc. This is the only solution I can suggest that doesn''t require a cooperative guest. Joseph.

libxenstat provides acces to basic domU statistics from dom0. The Host sFlow agent uses libxenstat to collect and export VM statistics using the sFlow protocol. http://host-sflow.sourceforge.net/ Peter On Wed, May 25, 2011 at 5:06 AM, Joseph Glanville <joseph.glanville@orionvm.com.au> wrote:> Hi, > > I am not sure how SolusVM gets its statistics - however it is possible > to get data from within domUs via VM introspection. > Take a look at the xen-access library etc. > This is the only solution I can suggest that doesn''t require a > cooperative guest. > > Joseph. > > On 25 May 2011 20:44, Jonathan Tripathy <jonnyt@abpni.co.uk> wrote: >> Hi Everyone, >> >> Given the "arms length" seperation between Dom0 and DomU, how is SolusVM >> able to provide stats on disk usage and RAM usage?

Hi Everyone, I have a dual core machine. In xentop, on a fully loaded machine, should the total cpu usage equal 200? Also, I upgraded on of my Windows VMs to 2 vCPU, however windows still reports just 1. Is this because I need to install the GPLPV drivers? Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Do you use Win XP? What do you see in your Windows VM when you look in device manager (don''t know exactly where)? ACPI uni processor or multi processor? If it is uni processor you have to change the files hal.dll, ntoskrnl.exe and ntkrnlpa.exe against the multi processor versions from a multi processor machine.

I have quad cores and seen in xentop values of 100+ % so, I think it is 100% per core.> Also, I upgraded on of my Windows VMs to 2 vCPU, however windows still > reports just 1.

I haven''t installed any GPLPV drivers (Should I?) I checked in device manager on the DomU and it indeed shows the 2 CPU cores: "Intel Xeon CPU" "Intel Xeon CPU" (I''ve ommited the model and speed just to keep it simple) However the task manager only shows one graph Any Ideas?

I remember seeing a distinct raise in performance for the disks after installing the drivers. I install them anyway, just for the Shutdown Monitor. Doesn''t hurt, though some get problems after. If you really want to be sure, there are commercial drivers available as well by for instance Novell.

Have you checked that you''ve got the ACPI Multiprocessor driver in use in Windows? In Device Manager, under the Computer node you should have ''ACPI Multiprocessor PC''. If instead you''re seeing ''Uniprocessor PC'' or similar, just update the driver and select the multiprocessor one instead. GPLPV is not needed for this, but I''d really recommend installing them for anywhere decent I/O performance.
