From: Martin Radev <martin.b.radev at gmail.com> Make sure the machine supports RDRAND, otherwise there is no trusted source of of randomness in the system. To also check this in the pre-decompression stage, make has_cpuflag not depend on CONFIG_RANDOMIZE_BASE anymore.

I have to collect cpuinfo and meminfo from hundreds of machines in preparation of updating our inventory and Xen version. Since we pin cpu and ram for dom0, this mangles the info. Is there way to get the real information? I know that xm top will give me the true RAM, but I need a non-interactive method. Specifically, I need the following real, unobfuscated/hidden info: Total RAM Processor (from

This patch series introduces a backend for kvm to run on IBM System z machines that uses the mainframe's sie virtualization capability. This work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with a 64bit linux host. Userspace will follow once we're done brushing it over. The patch queue consists of the following patches, which can be applied in sequence on top of kvm.git

...tions about it. 1. There no longer seems to be a seperate DomU and Dom0 built when I build from source. Is this the new policy? this would suit me, as I always used Xen0 kernels in my guest domains anyway. 2. Ive got me a vmx (vanderpool / intel virtualization tech) enabled processor (as shown in cpuflags in /proc/cpuinfo) - can Xen just use it from the default build (make world), or do I have to set any flags at compile time? it didnt winge about missing LibVNCServer, so I assume it wasnt built... ive looked in the manual, but it doesnt seem to say what I need to set to build a vmx version. 3.

Hi, Please let me know in case I am posting my question to the wrong forum. I apologize if that is the case! Here is my question: We run CentOS 6.3 on a server with dual Xeon CPU's. Our "dual blade" server uses this motherboard: http://www.supermicro.com/products/motherboard/Xeon/C600/X9DRT-HF.cfm We have two of these CPUs installed and working: Intel(R) Xeon(R) CPU E5-2620 0 @

Listmates (only posting to one list) Compiz has been running great with the 8.433 driver except for the libGL SONAME lockup on exit. see: https://bugzilla.novell.com/show_bug.cgi?id=344135 I just built and installed the 8.452 driver. Compiz would not start with the normal fusion-icon approach that I have been using with the 8.433 driver. This is on my Toshiba P35 laptop with an ATI
