similar to: Running Xen on current Opteron family?

Hello all! We are testing virtualization with two Sun X2200 M2 (2 x Opteron Dual Core) with Xen (3.1.3, locally compiled, Debian etch), KVM (Debian Sid) and Windows Virtual Server (Windows 2003 Server). We have tried paravirtualization and also full virtualization (Pacifica). In all cases we have experienced problems regarding stability in the systems, specifically erratic lost of network

I'm spec-ing a development server for some Haskell hackers. In particular, they need to be able to build and run the Glasgow Haskell Compiler (ghc), the x86_64 port of which isn't quite there yet. My current thought is to get an Opteron-based system, but load it (initially, at least) with the 32-bit i386 version of CentOS. That buys me near-term ghc compatibility. In the future,

i try another xen experiance on a AMD-Opteron 165 processor, but this happens: VmError: HVM guest support is unavailable: is VT/AMD-V supported by your CPU and enabled in your BIOS? cat /proc/cpuinfo: processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 35 model name : Dual Core AMD Opteron(tm) Processor 165 stepping : 2 cpu MHz : 1000.000

Hello, We have a few systems where udevd seems to failing silently on Opteron based Centos 4 boxes. Has anyone else seen this? -geoff

Hi All, I've just started caring for a dual Opteron machine. It has a 3Ware 9500S-12 RAID controller, a Tyan S2882G3NR motherboard, 10 IBM 400GB disk drives, and a 650 watt power supply. It has been behaving itself quite nicely until recently. The poor behavior started when I upgraded the OS from CentOS 4.1 (32 bit) to Centos 4.1 (x86_64). When running in uniprocessor mode, the system

I am about to lease another server to be a backup web/mail server with a replicated mysql database. The current live server is a dual Xeon 2.8Ghz. Would I do better to get another Xeon server or an Opteron based server? My concerns are compatibility of the database and the SSL certificate currently running on the Xeon machine. Are these concerns unfounded? TIA Mike

Has anybody here taken a HDD configured with an Opteron system, and then put it into an Athlon/64 and had it work? Are they interchangeable, like an Athlon/32 and a P3/P4? -Ben -- "The best way to predict the future is to invent it." - XEROX PARC slogan, circa 1978

Hi, I was wondering if anyone has had good experiences using R on Linux with dual AMD64 (Opteron) processors. I'm thinking of buying a couple of such servers, but I'd like to make sure R would work fine. The "R Installation and Administration" guide notes that there may be some problems with BLAS libraries. That's all I could find about R on AMD64. Please share your

Dear All, Just returned from vacation and was delighted to see that Centos 4.2 is now on the mirrors. Unfortunately the new i386 version is giving us problems on our dual Opteron workstations with Nvidia graphics cards... Basically, nine times out of ten, the boxes will hang when they try to re-load X... and just sit there with the keyboards Caps and Scroll lock LED's flashing. The only

Hi there We''re planning to buy a new server with a PentiumD with VT. Unfortunately we have some legacy server software which runs on Windows only and for that reason I have to install WindowsXP under Xen3. The problem is that I didn''t find too much documentation (tutorials, howtos, whatever) which describes installation and experiences with WinXP, besides some problem

Dear R-help: Has anyone tried using R on the the AMD Opteron in either 64- or 32-bit mode? If so, any good/bad experiences, comments, etc? We are considering getting this hardware, and would like to know if R can run smoothly on such a beast. Any comment much appreciated.

I'm putting together a spec for a big(ger) memory x86_64 host, and I hope some of you-all can help. I'm looking for success stories of hardware that folks are using in production environments, preferably with CentOS 4, with more than 4GB of memory per CPU. I know there are lots of mobos out there that can do this, but I'm looking for what folks really have running. Call me

I've been planning to build a dual Opteron server for awhile. I'd like to get people's suggestions on a suitable motherboard. I've looked at the Tyan K8SE (S2892) and K8SRE (S2891) but would like to find more Linux-specific experiences with these boards. Some features I expect are at least 4 SATA (SATA-300?) ports, serial console support in the BIOS, USB 2.0 and IEEE-1394

Hi Martin, When I attended the LinuxWorld Expo in NYC back in January, I chatted with some folks at the AMD booth, as well as guys from Penguin Computing (where we bought our Opteron box). I was told that the Operton has this somewhat strange setup that the memory is controlled by one CPU. The net effect of this being that when both CPUs are running, one might only be running at around 90%

Hey, I am currently considering a two machine Xen setup based on AMD Opterons, more precisely Dell R515s or R415s with dual Opteron 4274HE. Does anyone has some Xen setup(s) running on top of Opterons 4274HE, Opteron 4200 or Dell R515 machines and is willing to share some experience? In particular, I am interested in using Debian squeeze (Xen 4.0.1, Linux 2.6.32) for dom0 and most domUs. Any

Hi folks, an Asterisk (www.asterisk.org) box will be built with the following specs and I wanted to know if CENTOS has a built process/config/parameter/special distro to target the AMD Opteron Dual Core plataform: 2 amd opteron 265 dual core 1.8 Ghz 2mb l2 cache 2x1024 ocz c2-6400 dual channel gold GX XTC 2 Seagate 16mb cache 300 GB barracuda 7200 drives another 2 Seagate 500 GB 16mb cache

Hi I'm setting up a SIP gateway, serving quite a few potential users, and I wonder if I should purchase a Opteron or Xeon based system. Xeon has it's HT, but is it worth it? Has anyone tested Opteron on asterisk? Does it work well? There'll be no transcoding in this system - G.711A all way through roy

Anyone running Asterisk on dual Opteron Server? Are there any special issues in a 64 bit environment and what is the capacity curve like?
