Hello mates, Regarding this topic http://www.gossamer-threads.com/lists/xen/users/199969 I was wondering to find signed PV drivers to apply on Windows 2008 R2. I''m trying to execute Windows VMs under Xen 4.x and I did not get successful attempts with XCP pv drivers 1.0, and 0.5. Some people reports that XCP 0.1.1 driver is working on XEN 4.x. Where I can find this drivers right now? It is no longer available on Xen.org. Thanks in advance, Eduardo Kanashiro _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Eduardo, did you ever receive a response to this? The issue I''m running in to is while trying to allocate all Vcpu''s to the Windows 2008 R2 VM. The host processors are Xeon E5630''s, quad core with HT. I can set cores-per-socket=8 and Vcpu''s (at-startup & max) to 16, and see/utilize all Vcpu''s the host has. However when I install Xentool then the VM hangs on boot. I read the posts to the discussion you mentioned but am not sure it applies to XCP 0.5.0? -John From: "Eduardo Kanashiro (eduardo.kanashiro)" <eduardo.kanashiro@alog.com.br<mailto:eduardo.kanashiro@alog.com.br>> Date: Fri, 25 Mar 2011 15:37:36 -0500 To: "xen-users@lists.xensource.com<mailto:xen-users@lists.xensource.com>" <xen-users@lists.xensource.com<mailto:xen-users@lists.xensource.com>> Subject: [Xen-users] XCP WinPV drivers Hello mates, Regarding this topic http://www.gossamer-threads.com/lists/xen/users/199969 I was wondering to find signed PV drivers to apply on Windows 2008 R2.

RES: [Xen-users] XCP WinPV drivers
John, I did not receive any response regarding the question to XCP PV drivers 0.5.0. We have a similar environment running Windows 2008 R2 VM, and our host processor are Xeon E5402 quad core without HT neither turbo core, but I have experienced the same issue after install the latest versions of Xentool. My next step will be apply the same tests using different hardware types and kernel versions. I will post the results soon.

I never had a problem, but I always ask myself if I''m giving just half CPU when I assign 1 vCPU to a VM on a system which has HT enabled.

In that case their cpu doesn''t support HT. If I recall Intel reintroduced that (server side) with the 5500 family. As to your thoughts I''ve pondered the same. My company produces a student information system, and for most of our customers my department manages the servers on which the SIS is hosted. A few who are "self-hosted" have virtualized the web servers and in each case where they''ve had performance issues the common factor seems to be either "over subscribing" the host, or similarly, under-provisioning the individual VM''s. The reason I mention this is I''m currently working with a self-hosted customer running Vmware Vsphere Esxi on 4 HP blades, each with 2 X5570 processors. Our recommendation had been to provision each web server with the equiavalent of 1-2 cores, they allocated 1 Vcpu. The X5570 is hyperthreaded, and now that I find that they''re seeing average cpu utilization (of the VM''s) in the 50-70% range, I go back to our recommendation. While it may be splitting hairs, IMHO by allocating only 1 Vcpu they only allocated the equivalent of 1/2 of one core.
