Hi All, How does KVM handle multiple cores. I have an x5650 with 6 real cores that presents itself to my OS as 12 virtual cores (hyperthreading). Does KVM see 6 or 12 cores. And, can I tell KVM how many cores I want it to use? Am I misunderstanding how KVM works? What I am after is if my guest is 100% busy, I still want some power left over for my host. Many thanks, -T

Hi All, I am running Virtual box on a CentOS 5.5 x64 bit host. The guest is 23 bit Windows Server 2008 SP2 (not R2). Virtual Box bug 7606 is causing a customer of mine serious financial harm. http://www.virtualbox.org/ticket/7607#comment:3 I have tried in vain month or month over month to get Oracle to sell me a tech support contract, so that we can get some priority on this issue.

I'm setting up an Ubuntu?virtual machine?that will use 4-Intel Xeon CPU x5650.? I'd like to compile R with a BLAS but the question is whcih one.? Seems like the only free ones are GotoBLAS which I'm not sure is being maintained for newer CPUs and OpenBLAS for Loongson CPUs.? I saw a favorable report on OpenBLAS

Dear All, I am running R in a system with the following configuration *Processor: Intel(R) Xeon(R) CPU X5650 @ 2.67GHz OS: Ubuntu X86_64 10.10 RAM: 24 GB* The R session info is * R version 2.14.1 (2011-12-22) Platform: x86_64-pc-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=en_US.UTF-8

I''ve seen the Nexenta and EON webpages, but I''m not looking to build my own. Is there anything out there I can just buy? -Kyle

It has been over 3 weeks now, with no crashes, and me doing everything I can to get it to crash again. So I''m going to

The mystery gets more interesting... I now have a CentOS 7.3 Dell R710 server doing the exact same thing of rebooting immediately after the Xen kernel load. Just to note this is a second system and not just the first system with an update. I hope I'm not introducing something odd. They only "interesting" thing I have done for historical reasons is to change the following

All, I realize this is not strictly a PXELINUX question. So I hope you'll indulge me; hopefully some of these PXELINUX experts have seen this before. And can tell me what I'm doing wrong. Or confirm my suspicions. I have a test lab server at work. Split config. The network team manages the DHCP servers, points to our TFTP server. Test subnet has 3 DHCP pools. BIOS PXE, UEFI PXE and

As a follow up I was able to test fresh install on Dell R710 and a Dell R620 with success on CentOS 7.3 without issue on the new kernel. My new plan will be to just move this C6 to one of the C7 I just created.

I''m trying to use xenoprof in my machine (xeon x5650, westmere). While oprof works for this machine correctly, xenoprof doesn''t work properly. I want to use xenoprof in NMI mode (which is the opposite side of timer mode, right?) However, kernel message always shows that xenoprof works in the timer mode only. Is there any restriction or specs which is not

Hello List, I am testing a XCP1 CentOS 5 paravirt vm with CloudLinux. http://cloudlinux.com/ CloudLinux is a great product for shared hosting and I was evaluation same on a paravirt guest. I found a strange thing in XCP. CloudLinux provides xen kernel for DomUs and after installing the CloudLinux in a DomU it actually got 32 cpus inside. I had assigned only 2 vCPU to that DomU. To confirm this I

Hi, i need a server for 5000 clients and 50 sources at the same time Can you help me to choose the right server? I was thinking this one PowerEdge R710 n.2 x Intel Xeon E5502 (1,86GHz, cache 4MB, 4,86 GT/s QPI) 2GB Memory for 1CPU (2x1GB Single Rank UDIMMs) 1066MHz 2 X 146GB SAS 15.000rpm 3,5" hd hot-plug PERC 6/i RAID controller 256MB PCIe 2x4 1 gbit network card Thanks --------------

Updating my CentOS 6.8 Xen server with new 4.9.13 kernel yields a kernel boot message of a few like "APIC ID MISMATCH" and the system reboots immediately without any other bits of info. This is on a Dell R710 with 64GB RAM and 2x 6-core Intel CPU's. As an additional test, I installed and attempted to run the current "testing" kernel of 4.9.16 with the exact same results.
