I'm running a CentOS 4.4 VM on a Windows XP host with VMware Server, and have the problem that my clock runs too slow (it happens in VMware Workstation as well). It loses between 30 and 45 seconds every minute! This is a known problem and can be fixed by adding "nosmp noapic nolapic" to the boot command according to VMware tech note ID 1420. However, despite adding these

It appears as cpuspeed is not running on my centos 5 box(s). One is a biostar motherboard Am2 6400+ the other is Asus am2 4800+. If I do "service cpuspeed stop" it says OK, If I do a "service cpuspeed start" is says OK. However at no time is cpuspeed running. /proc/cpuinfo only shows the cpu running at 1000 Mhz. If I manually run "cpuspeed -C & " I now have

We are using CentOS-4.3 (x86_64) with Opteron servers, and noticed a problem with cpuspeed: If we reboot by doing "# reboot" or similar from a shell, the boot will hang not long after cpuspeed starts. The machine freezes: ctrl-alt-del doesn't work, and only pressing the reset button or a power cycle will restart the machine. If we reboot from power-up or by pressing the reset

After upgrade my laptop, I discovered a low performance on it. The laptop is a 2,73GHz Intel centrino and from some kernels versions to now, it had a good performance, the cpu scaling worked fine. Now, I discover that forcing in /etc/sysconfig/cpuspeed the governors and/or max/min speeds, it don't want to run more quickly. The laptop boots fine with the correct speed (usual speed), but when

Hey, folks, Sometimes my workstation bogs down... slows to a crawl. Using gkrellm, it's obvious the CPU is the laggard. The top utility confirms: the load average gets up over 4 at times. But this occurs when cpu stepping pegs the speed at 600MHz. This processor is capable of 1.5GHz and when it's allowed to run at that speed, the load average is under 2, which is fine. So the

Hello Sir, (This applies to the RH8.0 supplied syslinux 1.75-3 and the upgraded tftp-server-0.32-1 from RH Rawhide) I'm having fun remotebooting my ViA EPIA box (an ITX form-factor 800MHz ViA C3 semi-embedded pc), and have landed on pxeboot as the 'best tool for the job'. Right now I have it working, but the documentation found elsewhere on the web has confused me. Specifically,

One problem I've discovered in cpuspeed is that there are drivers missing: # cd /lib/modules/2.6.18-194.8.1.el5/kernel/drivers/cpufreq # ll total 72 -rwxr--r-- 1 root root 14408 Jul 1 21:40 cpufreq_conservative.ko -rwxr--r-- 1 root root 16168 Jul 1 21:40 cpufreq_ondemand.ko -rwxr--r-- 1 root root 7624 Jul 1 21:40 cpufreq_powersave.ko -rwxr--r-- 1 root root 12524 Jul 1 21:40

Hi, cpuspeed did not start on all my systems. CentOS 5.4 x86_64 /etc/init.d/cpuspeed start (nothing happen) Something is missing ? Thanks in advance for any idea.

On a new server's CentOS5 install, with nothing in the way of applications running yet, I noticed that the load average was sitting between 2 and 5 all the time, even though top told me CPU was 100% idle. Eventually I found that stopping the "cpuspeed" subsystem allowed the load average to drop down to near zero, as I would expect it to be. I have the default

Alle, I'm running V5.3 (newly installed) on an FJ E8020 laptop. The problem I have is when shutting down (*not* rebooting). NetworkManager fails to stop and after (during?) the postfix shutdown, the system seems to hang. I cannot access via another screen or remotely. I can't find any clues in the log files. I could use some suggestions on troubleshooting. Here are the active

Hi all, I'm wondering if I'm running into some dependency issues on my CentOS5 test-machines. I've installed with a fairly minimal package set, updated, removed old kernels and am now experimenting with iscsi and gfs. I think I need kmod-gfs to get gfs -support, but there is only a version that suits the base-kernel, 2.6.18-8.el5. " [root at node02 ~]# yum install kmod-gfs

Hi all, I've upgraded my mysql-installation from the previous 4.1.12 version to the new 4.1.20 version, and I've found that a daemon I'm using suddenly can't log into the database anymore. I've verified the problem with the mysql command; [root at sciream ~]# mysql -upostfix -p mysql Enter password: ERROR 1045 (28000): Access denied for user

CentOS 4.3 (SMP, x86_64, Athlon64 X2) with all pre-4.4 release updates applied. Since I ran into the Yum issue at the previous upgrade, I first did yum upgrade to get the list of packages (6 to install, 206 to update). I then did yum upgrade yum (which passed without issues) yum upgrade sqlite (which passed without isseus). Fairly certain that yum now works correctly, I wanted to just do

Hi people, I ran into one of these silly issues I'd like to share as I think the reason behind it may be a flaw in the current initrds. The setup; Dual-Xeon Intel-chipset motherboard. SATA-disk attached to ICH, onboard Adaptec SCSI-controller. Installed system, updated packages, no problems. Basic, non-LVM partition setup - OS-disk is /dev/sda, single filesystem-partition /dev/sda1 is

[I sent this to the RHEL4 list - but maybe someone on this list knows more] I have a number of dual CPU and dual CPU/dual core Opteron systems that are used as compute servers. In an effort to reduce power consumption and reduce heat output, I would like to make use of the PowerNow! capabilities to clock back the CPUs when the machines are idle. These machines are running a 2.6.9-42 RHEL4 kernel

I'm trying to replicate the features of the qemu curl plugin in nbdkit's curl plugin, in order that we can use nbdkit in virt-v2v to access VMware servers. I've implemented everything else so far [not posted yet] except for readahead. To my surprise actually, qemu's curl driver implements readahead itself. I thought it was a curl feature. I'm not completely clear _how_ it

I'm still testing this fix, so let's hold off the review for the moment. Also it may be better to specifically identify problematic servers rather than disabling this for every curl source. eg. I suspect that the problem is the Java server used by VCenter, so we might think about only disabling readahead for that single case. Rich.

This is the simplest solution to this problem. There are two other possible fixes I considered: Increase the documented limit (see http://libguestfs.org/virt-v2v-input-vmware.1.html#vddk:-esxi-nfc-service-memory-limits). However at the moment we know the current limit works through extensive testing (without readahead), plus I have no idea nor any way to test if larger limits are supported by
