Re: [H] Building a Virtualization box
Yes, Ben understood what I meant. It would make more sense and wouldn't seem innovative in any fashion if you had dealt with multi-displays before. I have two soundcards, onboard audio + pci soundcard w/ optical out. My htpc apps are assigned to direct audio output to the addon card. This machine isn't meant for 24/7 dual tuner PVR use or anything. I just use it to play my digital audio archives and encoded videos on an onkyo receiver and 42" lcd tv. I can control my media stuff with an IR remote. I'm testing out Linux but am mainly running this rig under Windows XP MCE 2K5. I have a dedicated htpc in my home but it is a low power system that streams video and audio off a server over a gigabit network (not necessary). I bought a pulled Core Duo mobile processor off of ebay for $30 and installed it on a mini-itx motherboard. H264 encodes play great with CoreAVC codec because it can utilize multiple processors. -Tharin O. Ben Ruset <[EMAIL PROTECTED]> wrote: There's no VM in what he was talking about.

Re: [H] X38 DD2 mobo's was Re: gigabyte MB's ?
Not bad. The last two weeks here have been crazed.. last Tuesday, we had an ice storm rip through KC, knocked power out to where the shop is for a few days.. which sucked balls, put everything behind.. and then at the end of it, an electrical whammo near my house burned our house down (literally!) so we've been doing all the hotel living and at the same time I'm working almost 24/7 getting all this s*(& done for people for Christmas. Tonight we sent out a set of boxes, a little later then I wanted, but they were trickier to get together; we didn't get 780i boards until 12/14, so it was really "to the wire" but I'm actually more impressed with TriSLI then Anand, and I'm actually really impressed with how well it works for people who do CUDA. Thought I'd throw up a pic: http://www.kctechheads.com/conroe/780i2.jpg I'll try to throw up some of the Solid State Drive setup we're sending out, but I'm not going to get that one to them by Christmas... I can't tell you how bad that sucks (but then again, no way to really do anything when you have no power; we sat for about 2.5 days just walking around and answering phones.. and yes, for next year, I'll get a generator) Nice to see Crysis detect highest settings across the board ;) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of j maccraw Sent: Wednesday, December 19, 2007 3:30 AM To: hardware@hardwaregroup.com Subject: [H] X38 DD2 mobo's was Re: gigabyte MB's ?

Re: [H] Grounding problems in Computer room
If simply turning a light on or touching a PC with your finger can trigger sound out the speakers, neither of those actions has anything to do with software. could be a ground loop problem. make sure the speakers and the computer are on the same 110 circuit, and you could try one of these between the soundcard, and the speaker http://www.radioshack.com/product/index.jsp?productId=2062214&cp=&sr=1&origkw=Ground+loop+isolator&kw=ground+loop+isolator&parentPage=search

Re: [H] Building a Virtualization box
Hmmm. So maybe then what I will do is run the WinXP gaming install as the host OS. Then I can run a WinXP or Ubuntu work VM on top. If and when video works I can then maybe have a HTPC VM running. The HTPC only serves up xvid and DVD playback, I don't do recording or HD with it. Possibly HD-DVD or Bluray in the future but I'm so pissed off at the format ways I'm trying to boycott it for now.

Re: [H] Grounding problems in Computer room
Sounds like a ground loop. Basically, the ground the computer is on is floating and not really grounded and allowing stray current. First thing I would do is check the outlet. You can buy an outlet tester for cheap at Home Depot or any such store and it will tell you right away if your outlet is wired properly. Might want to check all the outlets just to make sure they were wired correctly. The problem could be with the house ground. I would head back to your main breaker box and take a look. All of the wires coming in should have their copper grounds terminated at one of the ground plates along the sides of the box. Those ground plates should then be tied to a ground. In my case, the water pipes coming into the house. Sometimes they are attached to a metal stake that is driven into the ground. Check the cable on the computer and make sure the ground wire isn't loose or frayed at either plug. Check the power strip same way. I guess it could always be a bad power supply, maybe swap that out and see if it goes away. On 12/21/07, Anthony Q.

I heard about that through the speakers of my main PC (Logitech Z550 5.1 speaker system). What's the best way to rid myself of this problem? I admit to the very old and sloppy cabling down yonder. Hate to get into that mess! :)
[H] USB question?
Took and suggestion here and now have a Koutech Systems IO-P222 USB 2.0 I/O card. It is PCI. Choice was driven because this card has the pair of "m/b-like" pins so I can enable 2 of the 4 case mounted USB ports. Yes, this card also has 2 type-A USB ports pointing out the back also. The m/b has 2 type-A USB ports also, but has zero extra m/b USB pins. The m/b is really OLD! Question: Does a separate USB controller card require an IRQ for each of its' ports? It seems to grab an IRQ on each of the 4 PIRQ lines of the m/b no matter which PCI slot I place it in! So, I assume this is normal. If this is true, I'll keep playing card shuffle.. :) trying to keep the USB controller from sharing an IRQ with the Video card and NIC card. So far, it looks like a no-go with 3 cards, 4 PIRQ lines, and, 5 PCI slots. Have not found a pleasant segregation yet. Plus, the explanation in the m/b's user manual (abit bx6r2.0-440BX) makes little sense. Best, Duncan

There is a new VMWare on the way that does support video acceleration. There was a demo video on Youtube awhile back, and it looked really good.

Re: [H] Building a Virtualization box
On VMWare: 1.. You can bounce a guest without affecting either guests or the underlying OS. 2.. VMWare Workstation, Server both use the already installed OS and are simply applications hosting VM's - ESX is their proprietary OS (Linux Kernel) with the VM support functionality built in - obviously a much smaller OS footprint than Win2k3 or XP, but it really is a dedicated VM server at that point since you're not going to be using it for anything else. 3..For Server and Workstation I think you can really only tell it how many CPU's you want to dedicate and how much memory when you set up the guest. ESX allows much finer grained control and implements thresholds on resource usage. 4..Haven't thought about VM's for gaming sessions I would think there would be a pretty big performance hit. One gfx card is all I've ever had to work with on vm installs and have had 12 to 16 per box in server environments, though you're really only hitting the gui for maint and app installs. Workstation and probably to a lesser extent server should support the the functionality of the vid card since normally if the base OS can see it, the guest inside it can see it with ESX there's always issues with it being able to detect hadware.

Ben Ruset wrote: There's no concept of assigning physical hardware (beyond a nic) such as a video card to a VM (at least in the x86 world. You can in Solaris Logical Domains.) Each VM gets a virtual console, which you connect to with an app, or in the case of VMWare Server 2.0 beta, a web applet. Actually, to build on this, you can assign a raw storage device, such as a partition, to a VM and it will access it as local disk, as opposed to accessing storage emulated by the hypervisor in the form of a disk image file. Currently the limit is 2TB of raw space per VM.

Re: [H] NAS storage
I have a VMWare Farm at work - 15 boxes all running VMWare Server 1.0.3 under CentOS 4.4. They all talk to a Dell PowerEdge 2900 with 8 x 7200 RPM 500GB SATA drives, backed by a Dell Perc5/i hardware RAID controller. I have the RAID configured as RAID5 with a single hot spare, so I have 7 spindles for data. I'm exporting my data box with NFS. I have dual bonded GigE nics on the storage box, and each of my VMWare Server boxes talk to the storage box over a dedicated storage VLAN. (Each of the VMWare Server nics has a single Broadcom PCI-e nic dedicated to just storage traffic.) Performance on the box is abysmal. Any Windows 2003 64 bit VM that runs off NFS will bluescreen on while under any sort of i/o bound load. I moved some test images on over to our Netapp, and they run perfectly. I haven't been able to get into it too deeply, but this experience has sort of soured me on do-it-yourself NAS devices. Certainly they're probably okay for home use, but DIY storage needs to come a long way to match the i/o throughput available from dedicated storage boxes.
