Hi On a range of Dell servers containing Intel 64bit processors, 'virsh capabilities' reports the cpu differently on Debian Wheezy-amd64 and Wheezy-i386. The results given by the Wheezy-i386 version seem very wrong (since n270 is an Atom processor). Apart from architecture, the package versions of libvirt-bin are identical: 1.2.1-1~bpo70+1. /usr/share/libvirt/cpu_map.xml files are

Hello all, I was recently trying out NUMA placement for my guests on both x86_64 and ppc64 machines. When booting a guest on the x86_64 machine, the following specs were valid (obviously, just notable excepts from the xml): <memory unit='KiB'>8388608</memory> <currentMemory unit='KiB'>8388608</currentMemory> <vcpu

Hi everyone, After much waiting, Opus 1.1.1 is finally here. The main changes are: - x86 SSE, SSE2 and SSE4.1 optimizations contributed by Cisco, - MIPS optimizations contributed by Imagination Technologies, - ARM Neon optimizations contributed by Linaro and ARM, - many architecture-independent optimizations, - memory footprint reductions, and - several minor bug fixes. The quality of the

This is tangentially related to: https://bugzilla.redhat.com/show_bug.cgi?id=1372668 The problem in that bug is that we didn't pass the source CPU model (Sandybridge in that case) through to the target RHV hypervisor. So when the Windows guest booted on the target it gives an error about CPU hardware being disconnected (although it otherwise boots and works fine). This patch series

v1 -> v2: - Support for passing topology through -o glance. - Support for passing topology through -o rhv. - Use bool for acpi/apic/pae struct fields in virt-p2v. - Write the xpath expression in error messages instead of file/line. - Fix more memory leaks in virt-p2v cpuid.c. - Passes make check & check-valgrind. There may be some other minor changes. I believe that everything

I''ve been trying for several days to get a xen dom0 booting as described on Boris Derzhavets blog. I have been able to boot Jeremy Fitzhardinge''s pv_ops kernel under xen, but my X server wouldn''t start so I''ve been trying to get Andrew Lyon''s rebased opensuse patches to work. I have asked for help in the freenode ##xen channel but they

i try another xen experiance on a AMD-Opteron 165 processor, but this happens: VmError: HVM guest support is unavailable: is VT/AMD-V supported by your CPU and enabled in your BIOS? cat /proc/cpuinfo: processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 35 model name : Dual Core AMD Opteron(tm) Processor 165 stepping : 2 cpu MHz : 1000.000

Quick question. In my host, I've got two processors with each 6 cores and each core has two threads. I use iometer to do some testings on hard drive performance. I get the idea that using more cores give me better results in iometer. (if it will improve the speed of my guest is an other question...) For a Windows 2012 R2 server guest, can I just give the guest 24 cores? Just to make

Hi, I'm running libvert on a Debian 7 system. I have upgraded libvert and qemu from source (v1.06 and 1.5.0 respectively) and the problem persists. The guest OS is also a Debian 7 system running a non-SMP kernel. The error message from virt-manager is Error starting domain: unsupported configuration: guest and host CPU are not compatible: Host CPU does not provide required features: rtm,

Hello, Is there a way to configure the domain cpu in such a way that the info reported to the guest OS system will remain constant ? For example in older versions of of libvirt/qemu the cpu was reported as "QEMU Virtual CPU version (cpu64_rhel6)" but moving the vm on a qemu2.2.0 is is reported as "QEMU Virtual CPU version 2.2.0". Thanks.
