I have 2 servers: On both, I did yum update. One upgraded the kernel, the other didn't. Why? TIA, Dave Augustus

Hello list, I have a customer who is interested in standardizing on dell servers for asterisk deployments. Has anyone had success with a particular configuration? Anything specifically to watch out for?

Hello, I am trying to install Win2008 x64 on xen. However it always crashes with: 0x0000005b which from my research means incompatible CPU. Can anyone assist with this? How can I get x64 to work? cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 16 model : 2 model name : Quad-Core AMD Opteron(tm) Processor 2344 HE grep svm /proc/cpuinfo flags : fpu tsc msr pae mce cx8

Hi all, Does Xen dom0 mask CPU flags or what? I execute "cat /proc/cpuinfo" on bare-metal linux ,and get: +------------------------------------------------------------------------------------------------- | | flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 | clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm | 3dnowext

Running a 3.14.4 x86-64 SMP guest kernel on qemu-2.0, with kvm enabled and -cpu host on a 3.14.4 AMD Opteron host, I'm seeing a reliable kernel panic from the guest shortly after boot. I think is happening in kvm_unlock_kick() in the paravirt_ops code: divide error: 0000 [#1] PREEMPT SMP Modules linked in: CPU: 1 PID: 0 Comm: swapper/1 Not tainted 3.14.4-guest #16 Hardware name: QEMU

Even though Doug's out of the office, I'm submitting a patch to the ifcpu[|64].c32 COMBOOT32 modules for testing.

I just spend a few hours working with Redhat Cluster Manager. After working through some things that deal with Centos versus the *upstream provider*, I started configuring a cluster. Even to the point of using HP ILO as the fence. Anyone using this in production? With GFS ? I have used Heartbeat V1 in the past and I am deploying a new colo so I am looking at options. Any feedback is welcome.

Hi all, we are running two servers with Ubuntu 8.04 LTS Server with Xen 3.2 and two dual-core CPUs: processor : {0-3} vendor_id : AuthenticAMD cpu family : 15 model : 65 model name : Dual-Core AMD Opteron(tm) Processor 2218 HE stepping : 3 cpu MHz : 2613.394 cache size : 1024 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 fpu :

We're getting a new server. I'm considering installing 64bit fedora rather than the 32bit we use now. Is 64 bit a problem with asterisk? Any issues we should expect? sean

I am using a Asus M2A-VM mainboard with Athlon X2 2300 cpu. The mainboard features a AMD 690G chipset. I thought this hardware is amd-v compatible. While using xen with hvm I get the message: root@pluto:/etc/xen# xm create /etc/xen/win.cfg -c Using config file "/etc/xen/win.cfg". Error: HVM guest support is unavailable: is VT/AMD-V supported by your CPU and enabled in your BIOS?

Hi all, I have a machine that won't boot syslinux 4.02 but will boot syslinux 3.53. We've installed syslinux 4.02 on a number of machines but only this one has a problem. The problem is that the machine hangs entirely after printing "boot:" on the tty. The stanza being booted in /boot/extlinux.conf is: label xe # XenServer kernel mboot.c32 append /boot/xen.gz

LKP framework can guarantee that all the software environment are same on AMD and INTEL platform. INTEL platform always work well, after revert this patch, AMD works well. we tried below commit on AMD. 1) 25de7691a0e27c29c8d783a22373cc265571f5e9: bad 2) a82235843b102202766115e10003c9465a8b83ae: good the error logs(build/CMakeFiles/CMakeError.log) has no difference b/w 1) and 2) on AMD platform
