Performance of guest
...en I use it, I have a problem. My guest's performance is not very good.
For example, when I use Windows without kvm, the “lol” fps is 160, but my guest is only 135.
why? I only have one guest
what is the reason?
What can we do to promote my performance?
There are my some settings for me.
timer: hypervclock
cpu: 8 socket(intel@ core i7 7700k)
memory: 16G
GPU: 1060
network: virtio
my environment:
libvirt: 4.2
qemu: 2.12
windows: windows 7
host: ubuntu server 1604
If you need my detailed settings, please let me know.

Windows Guest I/O performance issues (already using virtio)
...the best 4k random read/write performance (mail and database workloads), but maybe I’m missing something at this layer too.
Questions:
1. Does my VM config look reasonable for the latest releases of windows? Are there features I should be using that will help performance?
2. Why does the hypervclock timer make so much performance difference in windows VMs?
3. Does my virtualized CPU model make sense? I defined Haswell-noTSX-IBRS and libvirt added the features.
4. Which kernel branch offers the best stability and performance?

getting oriented/networking
I've been using virt-manager and kvm with a disk image (as in the raw bits) from a physical windows 7 machine. Initial performance was dreadful, but improved as I switched to virtio and spice. I've been running linux VM's somewhat longer (much longer if you count kvm without libvirt).
There are lots of choices exposed by virt-manager. How do I find out what the choices mean, and

Re: Audio in Windows 10 VM is distorted. Using ALSA.
Hi,
I found the main reason for sound distortions on my system is guest timer
configuration.
The working one is:
<clock offset="localtime">
<timer name="hypervclock" present="yes"/>
<timer name="hpet" present="no"/>
<timer name="rtc" present="yes" track="guest" tickpolicy="delay"/>
</clock>

Windows 7 guest not starting with HyperV features enabled
Hi,
I have a Windows 7 SP1 Pro 64-bit VM which works fine on libvirt 2.3.0
and Qemu 2.7.0.
If I enable HyperV features
(https://libvirt.org/formatdomain.html#elementsFeatures) like "relaxed",
"spinlocks" etc - VM doesn't boot. "Starting Windows" text appears for
~2 seconds (no flying dots, no logo) and then it just goes to black
screen. If I switch HyperV
