I'm running a Windows 7 guest virtualised under QEMU/virt-manager on a Fedora 17 host and video performance seems poor. Mouse movement is laggy and unresponsive.
The guest is using a qxl video adapter and a Spice display. The guest Windows 7 has the latest spice tools installed. Changing spice to VLC in virt-manager doesn't improve things, neither does switching to a different display adapter (vga/cirrus). I've tried upping video memory, also didn't help.
I'm guessing this is video related as connecting to the Windows box directly via RDP is much more responsive.
Any ideas?
I try run qemu with win7 trough:
1. sdl -> fbdev
2. sdl -> nouveaufb(not work for me)
3. sdl -> directfb(not work for me)
4. sdl -> ggi(mouse not work) -> fbdev(or nouveaufb)
5. sdl(with USE="opengl") -> xorg(with nouveau opengl).
It all works same) video is smoothing, no luck)

I bought a Intel NUC Hades Canyon VR NUC8i7HVK PC and added an 8gb Kingston ValueRAM and 120GB Kingston UV500 SSD, running Windows 10, together with an Intel Realsense Depth Camera
I have tried to install the Realsense SDK, Realsense Viewer and Realsense Depth Quality tool aren't working.
They literally don't open without any error messages.
I have reinstalled it numerous times.
I'm intending to use it with the Nuitrack library and Unity for Skeleton tracking and have successfully done so with my regular computer.
However, now nothing seems to work anymore.
I have no idea how to go about it, since I don't know where to look. Any ideas?
Keyboard and mouse works in bios, but when in win7 installation screen, they are failed?
After google, mostly the problem is win7 is lack of the USB 3.0 drivers, and they just tell us to use USB2.0 port, or even use PS/2 port.
Then how can we deal with only with USB3.0 or their suggestions is not suitable for us?

stuck in firstly settiing windows?

If you meet above problem, this link may help you and save time.
I have try to use USB2.0, but most of BIOS settings is not found in my computer. After lots of retry, I found this video that tell us how create a Windows 7* installation image to include USB 3.0 drivers.
this tools required:
Win7 ISO
windows-usb-dvd-download-tool to install ISO into your USB
Windows-7-USB-3-0-Creator-Utility to install USB 3.0 drivers
If link is failed, try to search tools'name.
update 2
After above actions, my compute is stuck in setting compute(set name).
==> I solves it by set BIOS-USB_SETUP's USB Virtual KBC Support Enabled, the refer link is miss.
Finally Done...
I am having some issues with my RPi2. As I said in the title I have Raspbian installed. The system runs smoothly when I navigate files etc. But when I try to use the Internet Browser OR Navit (I am working on a project and I want to use the RPi as a navigator) then the system gets laggy and very very slow. I also notice that in the right top corner the cpu usage goes about 30% (sometimes more).
Raspbian is installed in a 16Gb Class 10 SD Card. I have expand the system via raspi-config and I have about 9 gigabytes of free space. I also have HDMI, keyboard and a wireless mouse connected.
Any ideas/suggestions?
Thanks in advance!
my external monitor stopped working today after restart. I found the computer on during the night. Running win 10 64b on Lenovo U430p.
The monitor worked fine the whole time. I can see windows logo while booting, but then it says no signal. When I uninstalled the video driver it worked (login screen, desktop, res 800*600), until windows installed driver over it. I tried getting newest driver from both Lenovo and Intel, but with no results.
Did anyone experience this issue as well? I read about people having this with new computer but not to happen from the blue and ususally at least disabling the video adapter helped.
Thanks!
Haven't found real solution and it seems to be a problem of Intel graphic cards.
However reverting to most basic driver windows can offer did the trick
Uninstall driver
Rollback driver
Using wushowhide.diagcab utility (https://support.microsoft.com/en-us/kb/3073930) disable updates for all video card drivers
Windows Phone 7 Emulator runs in slow mode... even tho my system supports VT
I just updated my Sony Vaio FW21E's bios update, now VT is enabled, but emulator still runs in same old slow mode.
How can I run the emulator in VT mode.
Please advise.
Make sure your system meets the requirements laid out here.
Setup and System Requirements for Windows Phone Emulator
In particular, verify your gpu is being recognised by the emualtor by checking the frame rate counters are visible.
This will not happen if your display driver is not WDDM1.1 compliant and minimum Directx 10.
I also recommend trying a Win7 install on a spare hard disk if you're running Vista. This consistently produces positive results when problems of this nature are reported on hardware compliant systems.
I had this issue on my Mac running bootcamp. I read in some forum what appeared to be the weirdest solution ever.
If I had Netflix open, streaming a movie, my emulator would work perfectly. When I did not, it would just be the slowest thing.
I read somewhere that could be related to drivers and hardware acceleration. So Windows Phone was not 'hardcore' enough to trigger turning on the acceleration on the video card but when you had the streaming ON it was using it, making it fast.
You might try that out... I know it sounds dumb but it worked for me.
The HD3450 should be ok as its a DirectX 10 card I beleive
As said above the card needs to be WDDM1.1
you can check this by running 'dxdiag' in the run or search box in vista. go to 'Display 1' (or just Dispaly) tab, and on the right there will be DDI Version - should be 10, and Driver Model - should be WDDM 1.1.
If its not compliant with WDDM1.1/DX10, it will work ok but you wont get things like aminmations on page transitions etc.
