Well, I've been needing a new server motherboard/processor for a while now.
Something speedy enough but budget. Like no more than $200 including processor, RAM, motherboard, and cpu fan. If you come up with anything good let me know.
Every time I look I read something bad about what I am about to get and am frozen with indecision...

I think it all sucks.
There seems to be less and less of fewer and fewer things.
Certainly there's lots of motheboards, but not as many as there used to be.
Same thing with chips.
Anyway, I copped out and went with a combo package. $60 got me a sempron 3000 with motherboard.
It's got video and ethernet on it, and 2 184 pin slots for memory.
There's 240 pin 200 pin and 184 pin memory now.
No idea what the others are like, but gone are the days of lots of slots.
In soviet america you buy 1 chip with all the memory you want. You want 2 gig, you buy a 2 gig chip.
It's even got a serial port on it.
But it's not fast or modern, but it's cheap and has plugs for my non SATA hard drives.

So out of sheer boredom, I've been playing with the dying machine.
I've noticed 2 more things.
I can boot into the bios and it works just fine.
It will boot to grub and then as soon as it changes video mode to show the ubuntu slash screen it reboots.
Sometimes it reboots quickly and somtimes it waits a few seconds. During that wait, the power button doesn't work, which to me means some part of the motherboard shutdown, but wait long enough and it will reboot.
So it's starting to sound like either the video card (which I don't have a spare to replace with) or heat. I took the heatsink off and put more goop on, and blew air over the fan (oh my the grey dustcloud that came out of doing that) but no change.
Any more thoughts?

I am grasping at straws...

  Is the video card square to the motherboard when everything is installed in the case?  Cheap cases sometimes don't fit quite right.

I definitely sounds like the vid card is the problem.

Thanks guys. The Sempron might be enough for me. I had a Duron 800 and I wanted to go significantly up, I was kind of thinking of going up in processor class because I want to run some bigger things, like maybe Oracle. Not a lot of load but just to run it decently at all takes some power. And the Sempron is basically the successor to the Duron, so not really a step up.
But I dunno, it's years later.. and the processor that comes in that $60 deal actually kicks the ass of my old processor.. more than double processor speed, FSB at least double.. etc etc... And probably a whole bunch more improvements.
So maybe I should just pay the $60 and spend my money stuffing it full of as much memory as it can handle, and maybe buy some new hard disks instead of keeping the old ones...

ahhh, that's the rub it can't handle a lot of memory, like 2gig max or something.

I am really surprised how few motherboards can handle more than 2 gigs of memory.
If you want to run oracle, I wouldn't get the sempron thing, I'm getting it because I only need a minimally functional linux box to run a webserver and mail and stuff like that.

That's a pretty good deal I think. Although what's surprising is that they'll throw in all the big stuff, but no fan/sink.
I never understood that. It's like buying a wheel without a tire, why do the even sell them separately?

Subject: Re: LVM

If you can boot a Xen VM off a raw disk partition, then most likely you can boot it from an LV as well. They're both implemented as block devices.

LVM is great for that sort of thing. I recently finished building a SAN appliance out of a Linux machine with fibre channel target mode drivers, and used LVM to manage the disk slices being exported to the initiator machines.
Performance was *really* good. Now we're thinking about using it in a virtual infrastructure to keep the storage separate from the VM hosts. VMware Server was being considered, but perhaps Xen should be evaluated as well. I take it you need hardware VT if you want to run 'doze as a guest OS?

VMWare Server is obsolete already. Xen or VMware's hypervisor product would be the way to go for virtual infrastructure.

Either of those choices would be more optimal, but if you have a host system without hardware virtualization, your choices are more limited. Xen requires hardware VT in order to run unmodified guests, and VMware's hypervisor requires an expensive and Windows-based management product in order to manage it.

VMware Server runs unmodified guests on an ordinary host operating system.
Low-end, but it gets the job done.

Oh, I assumed you were virtualizing Linux-on-Linux for purposes of consolidation and management flexibility. If you're just running Linux on Xen, there's no reason to want to run an unmodified guest; paravirt is faster.

We are indeed virtualizing for consolidation and management flexibility, but unfortunately a portion of the target machines are running Windows.

I just came across the cutest bug.
using bash, try to autocomplete postfix.
as in /etc/init.d/post<tab><tab>
you get a get_cword: command not found error.
Apparently there's a patch for it, also happens for umount I guess.
But how weird is that.
