    Well, I cannot say anything about the package manager but there's no decent Fedora mirror in my country (I have looked for one several times). Whereas the Ubuntu mirror is 1ms away and I download...

    This doesn't seem to be the case. From the link above:



    I interpret this to mean that there are no changes to host or guest drivers. Sounds too good to be true. But I guess it has performance...

    Does anyone here thinks that even LTS releases see production deployment the next day after release? It will take months if not years. So there should be no big harm in using the latest kernel if it...
  4. I don't think that's the case. From...

    I don't think that's the case. From https://01.org/xen/blogs/srclarkx/2013/graphics-virtualization-xengt



    With VT-d there would be no need to emulate these things. For the pass-through...

    The article clearly states that it's different. Whereas passthrough gives the GPU to a particular VM, XenGT allows for sharing of the GPU between several VMs.

    Thank you Michael for using real "spinning rust" HDD for the tests. The Raptor is not your typical HDD but it should be much more representative for real world scenarios than pure SSD tests.

    Dude, consider upgrading your Ubuntu to 13.04 or...

    Dude, consider upgrading your Ubuntu to 13.04 or even 13.10. 12.04 is from more than a year before the Haswell launch. You can run your server-related stuff in a virtual machine where you can keep...
  8. Game console effect?

    Maybe with the RaspberryPi we will witness the game console effect? When every device is (almost) exactly the same as every other a lot of optimizations can be done for that particular device.
  9. More specifically, I would like to get an...

    More specifically, I would like to get an Supermicro X9SCL-F main board. It has IPMI 2.0 compatible BMC module with its own graphics controller. It doesn't make use of the CPU-integrated GPU. Then...

    1. VNC is insufficient. I want sth with synchronized audio and USB redirection. Something along the lines of SPICE. I want to connect to the VM, not to some server inside it. Because I might need to...
  11. That would be great. I would really like to have...

    That would be great. I would really like to have a setup where I have a server hidden in the closet that runs a virtual machine for my desktop and have full GPU acceleration while being accessed...

    I wonder if that prevents the host kernel from using large pages. I would have though that's particularly good fit for virtualization. I think the current Linux kernel can use large pages...

    What about windows?

    I wonder if the MMIO support is available on Windows. The paged linked in the article says:

    3. The operating system must have a unified buffer cache in order for the memory-mapped I/O extension to...

    However (and I quite from Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families Datasheet):

    The processor supports the following Intel VT Processor Extensions features:
    • Large Intel...

    I have to concede here. On closer inspection VT-d is more common that I though. But the later posts show that it's not so simple. I still maintain that it's very hard to pick a CPU-MB combo and be...
  16. Oh, I think it's quite uncommon. Especially on...

    Oh, I think it's quite uncommon. Especially on Intel processors. You need a Xeon processor and the corresponding mainboard. For AMD also not all chipsets support it. Which is rather strange, because...

    I wonder where the performance penalty comes from. Especially with full disk encryption. A modern processor with AES-NI can encrypt/decrypt several gigabytes per second! Way more than the 100-200MB/s...
  18. VMCS shadow processor support

    I wonder what are the "new intel processors" that support the VMCS-shadow feature. Does anybody know this? Is there any documentation on which processors have it? How does intel market it? Intel used...

    I've read somewhere that Windows is different in that respect but I don't remember the details. It's much clearer for Linux. It's essentially a performance optimization. When userland calls into the...

    I think you are mixing the issues somewhat. The lower 4GB of physical address space are never entirelly mapped to RAM. There are regions there dedicated to I/O. Yes, the discrete graphics cards are...
