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

questions on clock catchup
In http://libvirt.org/formatdomain.html#elementsTime , we could find there are
three attributes of catchup tickpolicy: limit, threshold and slew.
"
The catchup element has three optional attributes, each a positive integer.
The attributes are threshold, slew, and limit.
"
The xml format likes:
<clock offset='utc'>
<timer name='rtc'

libvirt on OpenStack
Hi,
I am running OpenStack Cluster and use libvirt + cgroup to limit vm’s performance
https://wiki.openstack.org/InstanceResourceQuota
What I am confusing is..
1. After running a vm instance with some croup limit applied, I can’t find any related cgroup settings.
2. Can I change limit value after instance is running? like change disk_read_iops_sec from 10 to 20.
One of the xml file like below.

Network speed between two guests on same host.
Hi,
I've got two hosts. Most of my guests are Windows systems. I'm using LANBench to test network performance.
1) From an physical PC to a guest (it doesn't matter on which host), I get almost 1Gb/s. They are connected through a 1Gb/s swich => very good!
2) From a guest on one host to a guest on the other host => plusminus 1Gb/s => Okay!
3) Between two guests on the same

problem with disk virtio driver
I just ran into a problem I can't make heads or tails of, so I'm hoping to

1.2.20
I'm creating a domain with the following config:

Cannot boot libvirt guests with OVMF. Raw qemu-kvm works as expected
Using:
edk2.git-0-20150803.b1141.ga0973dc.x86_64
edk2.git-ovmf-x64-0-20150802.b1139.gb234418.noarch
On Fedora 22.
Provisioning a i440FX system in virt-manager and attempting to boot
results in successful EFI initialization, but the VM exits ungracefully
after the bootloader (with F22 and CentOS 7 installer images). There's
no really useful information in any of the logs.

virtual drive performance
Hi,
I'm investigating a performance issue on a virtualized windows server
host that is run on a ubuntu machine via libvirt/qemu. While the host
can easily read/write on the raid drive with 100Mmb/s as observable with
dd, the virtualized windows server running on that host is barely able
to read/write with at most 8Mb/s and averages around 1.4Mb/s. This has
grown to the extent that the

Adjusting vram for windows/photoshop
Hi,
I have a fedora27 system with a win10 guest trying to use photoshop
2015. I've adjusted the vram parameter for the guest to 512M with QXL,
but photoshop still reports "3D features and some filters require
512MB vRAM and photoshop has detected less than that on your system."
What is the proper way to adjust the vram value to provide at least 512MB vram?

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
