similar to: libvirt does not show same CPU Model as /proc/cpuinfo for CPU Model info.

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 , thanks for comments . I tried now with force options for CPU flag which were not supported . Now the command with non fully supported CPU model gets executed , But i am surprised to see that still Guest cpu model is not changed and still same as host cpu model(SAndy Bridge) Why don't i see the model as HAswell now , could you please comment. Command used : virt-install

Hi, today I tried to configure a guest using Virt-Manager and used the "copy host cpu configuration" option which resultet in a "Sandy Bridge" model. What I noticed is that for example the "aes" extension is not available in the guest even though it is available on the host cpu. This is what the host cpu looks like: model name : Intel(R) Xeon(R) CPU E5-2650 v3 @

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

hi, yes we are talking about same host here. You could've just used -cpu host-model-only >> I dont want to host model ( it is working with host model) . AS KVM seems to allow support Haswell with native commands . Does this mean in my case KVM is allowing software emulated cpu model. Can libvirt allow software-emulated for non host model ? if yes how . thanks On Tue, Jan 24,

Hi, According to virsh capabilities I only have the following cpu features: <cpu> <arch>x86_64</arch> <model>IvyBridge-IBRS</model> <vendor>Intel</vendor> <microcode version='32'/> <topology sockets='1' cores='4' threads='1'/> <feature name='ds'/>

Kashyap: I have not tried integrating your guest xml but I will look over it today when I get a chance. Thank you. Martin: Below is the output from /proc/cpuinfo. Let me know if there is anything else that would be helpful in debugging this. Thank you, Michael Giardino processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 60 model name : Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz stepping

hi , I am creating Guest by Libvirt tool " virt-install" with cpu model as host. After Guest creation i see Guest Missing quite no of flags which Host was having . What could be the reason for this ? I am expecting all flags of Host to e present in Guest as well when choosing cpu model as host . Guest : processor : 19 vendor_id : GenuineIntel cpu family : 6 model

I have been tied up with other work and Holidays. Now back to some server work that is long overdue. I lost an old server yesterday so it is crunch time. I believe my new platform is suppose to be an x86_64. The order form says 64 bit. I booted Centos 6.3 i386 liveCD to check the system out before an install. uname -i reports i386 dmidecode -t processor reports Characteristics of 64

Hello everyone I want to know how can I use libvirt to detect what cpu features a virtual machine will see. I guess I could do it in following way: 1. if cpu mode is 'custom', use 'virsh cpu-baseline --features' on the cpu model to get model features. 2. if cpu mode is 'host-passthrough' or 'host-model', do a 'virsh capabilities' to list cpu features of
