Re: LibVirt query CPU Model support and restore operation
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

libvirt does not show same CPU Model as /proc/cpuinfo for CPU Model info.
Hi ,
Created new thread .
Environment:
Bare Metal server + CentOs with qemu/KVM +libvirt for virtualization
Guest Instantiated with virt-install with forced CPU model like below
virt-install --virt-type kvm --name compute-0 --cpu
Haswell,+fma,+movbe,+fsgsbase,+bmi1,+hle,+avx2,+smep,+bmi2,+erms,+invpcid,+rtm

CPU model and missing AES-NI extension
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 @

Re: LibVirt query CPU Model support and restore operation
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

Fwd: Haswell 4770 misidentified as Sandy Bridge
Hi,
I'm running libvert on a Debian 7 system. I have upgraded libvert and qemu

guest OS is also a Debian 7 system running a non-SMP kernel. The error
message from virt-manager is

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,

Hello ,
It was working good working with kvm management tools using libvirt .

But then i got annoyed when management tool did not allow me to change the

Way to detect virtual machine cpu features
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

CentOS 6 / Intel CPU support
https://access.redhat.com/support/policy/intel
shows mainly Xeon CPUs. What about
Intel Core i7-6700 Quad-Core Skylake
has the current EL6 variant support for it?
Any experience? Feedback would be greatly appreciated.

How to best I/O performance for Window2008 and MSSQL guest VM
Hi There,
I've moved some Windows2012 with MSSQL VMs from an hold ESXi 5.5 machine
to a more recent and powerful machine running Fedora 24 x86_64 and related libvirt + KVM
virtualization. I've moved the VMs filesystem to LVM slices and installed the VirtIO drivers
in to all Windows VMs. I've also set both Disk and Network interface to work using VirtIO.
So far so good everything works

Increasing video memory available to Windows
Hi,
I have a fedora25 system with a Windows10 host and would like to use
it for photoshop. However, it complains the video memory is too low.
I'm using the QXL driver and it appears to be limited to 256MB? I've
installed the Red Hat QXL driver in Windows.
I have 4GB of memory allocated overall, and could allocate more if necessary.
How do I increase the available video memory? Photoshop
