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...

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...

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...

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...

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...

Dude, with amd64 all programs use the larger general purpose register file. The compiler automatically generates code for that. Same for SSE2 - that's the way amd64 implements FP math. No x87 there....

Mike, on Linux you really want to use 64-bit kernel even physical RAM of 1GB (or larger, of course). Due to the way Linux partitions the virtual memory space, there's only 960MB in the...

In 64-bit mode the processor has twice the number of registers. So more data can be kept there. Also, the calling convention uses more registers to pass values - no need to put them on the stack for...

What is the state of SPICE these days? The official site is pretty stale. About a year ago I tried to virtualize my desktop with KVM/SPICE but I found the performance pretty bad. And the clients...

Sorry for being off-topic but do you know how can I discover the Xresources used by a particular program, say xterm? Is there some command that lists them?

I think the answer is right there.

Yeah, really interesting. But does it support SCSI adapters? I've been unable to find reliable information about whether and which SCSI adapters Haiku supports. I've tried browsing the source too but...

I don't have a problem with using an INI file. My understanding is that it will be manipulated by software but of course the settings have to be kept somewhere. My problem is with the rather...
