I want to setup 3D acceleration in kvm. I have asked google but all I could find is that I have to passthru my PCI card what seems to make the grafics unavailable for the host. I do not really get this since than, I would need 2 cards to avoid a black screen on the host? Is that correct? If so I will go straight back to virtual box...
virtio vga supports 3d acceleration, but so far only linux drivers exist, so it depends on what you want to run inside the guest ...
I too have struggled with slow GPUs in the virtio domains. I ended up using lubuntu or xubuntu to get better performance. It is not possible by now as far as I know.
I read recently about the new GPU virtualization for new Kernels here: http://news.softpedia.com/news/linux-kernel-4-10-officially-released-with-virtual-gpu-support-many-features-513077.shtml . It looks it is a work in progress.
I found this article https://medium.com/#calerogers/gpu-virtualization-with-kvm-qemu-63ca98a6a172 just now. You may give it a try and let us know if that worked for you.

When playing certain games or viewing certain websites, my computer will suddenly crash and my monitor will display "HDMI no signal" the computer cannot be restarted without unplugging it from the wall. Upon viewing the crash report I see event 10016 related to permissions I think, but I'm a moron. Any and all solutions are greatly appreciated. Relevant components are as follows:
Graphics Card: RTX 2080
Power supply: EVGA supernova 1000g2
Storage: Sandisk 500Gb
CPU: Ryzen 2700X
Monitor: Both HP EliteDisplay E222 and another HP monitor
Since you are not supplying your q with the crash report, I can only suspect your problem is rooted to either one of these:
Bug in the accompanying display driver and/or directX installation
Proposed solution : try and obtain the latest version of your RTX 2080, do a 2D and 3D test run afterwards to ensure everythings proper
Fan or cooling related issue. Some games might force your hardwares to work harder, especially over continuous use. Check your fan and coolings to ensure they are moving and cooling as fast as they should. Also install a temp monitoring software if you need to be extra sure.
Hope those help m8
I am grad student, and I am considering setting up my dream home workstation/art tool/entertainment device/all-purpose everything. I'm wondering if what I want to do is possible (and practical), and if so, get some suggestions and warnings from people who know more about virtualization and hypervisors than I do:
Aim: Set up a 2-4 headed computing station that is optimized for using different OS'sfor different tasks I do. I want to keep my work/play streams separated, and have control over the resources that each one is allowed. For example, one head would be Windows 10 for audiovisual work, media playing, and maybe some gaming. Another head would use Linux and be used mainly for data science (mostly R and Python), and some hosting for purely local use (such as running an instance of the Galaxy bioinformatics server, which I only plan to access locally).Finally, I want a VM that is purely devoted to web-browsing, probably some lightweight Linux distro.
I want each OS to have it's own keyboard and monitor(s), but ideally I want to copy-paste between OSs. The idea is to just swivel my chair to move between operating systems, or even to have one person using each.
What I think I need:
A hypervisor with PCI, USB, and network controller pass-through.
Two video cards,one each for my Windows and Linux workstations (with the web browsing VM using the on-chip CPU graphics). Obviously, a mobo and CPU that support full virtualization.
A USB card with multiple separate controllers, so that I can use a different controller for each OS. Something similar for network interface cards.
Separate SSDs for each OS and its apps.
Some sort of storage pool (probably ZFS based) to hold the bulk of my files, shared so I can access them from either guest. Ideally, I'd like to to be in a separate enclosure, but I don't trust eSATA cables (they seem to fail frequently) and care about speed of database access, so I'll probably put the drives inside the main case, even though that will make future migration more annoying.
Something like SPICE for KVM, so that I can copy and paste freely between OS's.
Is there anything I am overlooking?
What hypervisor or similar solution is best for what I want to do? I am leaning towards KVM, but am far from committed.I will consider paid solutions if there is a compelling reason to use them.
What are some pitfalls I should be wary of?
kvm will work here ideally, a lot of tutorials and lot of intel based configurations working like a charm
zfs can't share your data, u need nfs or samba share on host machine
Synergy software is for you.
I just bought myself a new laptop(check link for details) and i was wondering how could i know if my laptop is compatible with running DDR5 ram, instead of DDR3. I have 2 slots and i really want to upgrade to DDR5. I have been searching on google for motherboard specs, but i am a little new to this stuff. So, can anyone please tell me if my laptop can run DDR5? Thanks a lot.

There is no DDR5 available, maybe you are confusing with GDDR5 which is embedded on a discrete graphic card ?
The listed laptop is compatible with DDR3L (low voltage)
I tried using "Kinect for Windows" on my Mac. Environment set-up seems to have gone well, but something seems being wrong. When I start some samples such as
OpenNI-Bin-Dev-MacOSX-v1.5.4.0/Samples/Bin/x64-Release/Sample-NiSimpleViewer
or others, the sample application start and seems working quite well at the beginning but after a few seconds (10 to 20 seconds), the move seen in screen of the application halts and never work again. It seems that the application get to be unable to fetch data from Kinect from certain point where some seconds passed.
I don't know whether the libraries or their dependency, or Kinect's hardware itself is going wrong (as for hardware, invisibly broken or something), and I really want to know how to detect which is it.
Could anybody tell me how can I fix the issue please?
My environment is shown below:
Mac OS X v10.7.4 (MacBook Air, core i5 1.6Ghz, 4GB of memory)
Xcode 4.4.1
Kinect for Windows
OpenNI-Bin-Dev-MacOSX-v1.5.4.0
Sensor-Bin-MacOSX-v5.1.2.1
I followed instruction here about libusb: http://openkinect.org/wiki/Getting_Started#Homebrew
and when I try using libfreenect(I know it's separate from OpenNI+SensorKinect), its sample applications say "Number of devices found: 0", which makes no sense to me since I certainly connected my Kinect to MBA...)
Unless you're booting to Windows forget about Kinect for Windows.
Regarding libfreenect and OpenNI in most cases you'll use one or the other, so think of what functionalities you need.
If it's basic RGB+Depth image (and possibly motor and accelerometer ) access libfreenect is your choice.
If you need RGB+Depth image and skeleton tracking and (hand) gestures (but no motor, accelerometer access) use OpenNI. Note that if you use the unstable(dev) versions, you should use Avin's SensorKinect Driver.
Easiest thing to do a nice clean install of OpenNI.
Also, if it helps, you can a creative coding framework like Processing or OpenFrameworks.
For Processing I recommend SimpleOpenNI
For OpenFrameworks you can use ofxKinect which ties to libfreenect or ofxOpenNI. Download the OpenFrameworks packaged on the FutureTheatre Kinect Workshop wiki as it includes both addons and some really nice examples.
When you are connecting the Kinect device to the machine, have you provided external power to it? The device will appear connected to a computer by USB only power but will not be able to tranfer data as it needs the external power supply.
Also what Kinect sensor are you using? If it is a new Kinect device (designed for Windows) they may have a different device signature which may cause the OpenNI drivers to play-up. I'm not a 100% on this one, but I've only ever tried OpenNI with an XBox 360 sensor.
I have a kernel 2.6.31 booting from a USB stick using Intel 915 based KMS to get to graphics mode. It appears to be setting itself to the native resolution and its booting nicely into framebuffer console with a beautiful Tux logo!
Question is, how do I access the inteldrmfb? How do I get it into /dev? Will udev do this for me?
What is the API for programming the framebuffer directly?
Thanks,
FM
Try the directfb library?
edit:
The kernel API is documented in linux/Documentation/fb. See Documentation/fb/framebuffer.txt in the kernel git tree, for starters. Doesn't seem to have changed for a long time. Probably still accurate. Kernel<->user APIs tend to be stable.
http://www.linux-fbdev.org/HOWTO/index.html. May be useful, but it's probably not as useful as the kernel docs.
Probably, as you say, the library source would be the best reference on how to do things.
If you're not seeing /dev/fb0, even though you have the module loaded, then maybe you need to configure udev for it? Or just mknod yourself.
