similar to: Fast clock under VMWare

I'm running VMware Server 1.0.6 on a CentOS 5.2 host and am having some clock difficulties. Host OS is x86_64 running on 1.9 GHz AMD Sempron, nVidia chipset. Guest OS's are 32-bit FreeBSD (clock works fine after disabling ACPI, setting the clock source to the PIT, and running the guest tools), WinXP (unknown clock status), and i686 CentOS 5.2 (here is the problem). I've tried pretty

Hi, I followed the discussions regarding the "time moved backward" problem and the use of ntp in such cases. At our department we are running two dovecot servers within an vmware server environment, and unfortunately the timedrift (with ntpd active) exceeds sometimes up to 30 minutes virtual drift within 10 minutes realtime (mostly into future). This is due to some overcorrections

Hi everyone: Just a follow up on the fast clock issue: "Can you double-check that 'cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq' outputs the same number as your 'cpuKHZ' setting in your config.ini file?" There is no cpufreq directory under /sys/devices/system/cpu/cpu0; all I see is "cache" (dir), "crash_notes" (a file) and

Hi all, If you are using the kernel divider= option in your vmware quest, you are probably aware of the bugs reported at: https://bugzilla.redhat.com/show_bug.cgi?id=315471 Someone @redhat "confirmed" the fix is in the test kernel -92. I tried it but it seems to have the same problem as before - when used with clocksource=pit, it hangs on bootup. Wonder if some of you can test this

We've noticed our fully-virtualized KVM guests' time keeps getting faster, despite running ntpd. A quick google reveals this to be a known problem with virtual guests. It seems there are a variety of solutions, some apparently vendor-specific. What is the best practice as of now for KVM guests? * Setting independent_wallclock=1 (or is that a xen-only thing)? * Passing kernel

Howdy, I am having time-drift issues on my CentOS VM. I had referred to following documentation: http://wiki.centos.org/TipsAndTricks/VMWare_Server , however it didn't help. I used kickstart for creating this VM and I am listing important steps in ref to timekeeping issue. Any comments or suggestion would be appreciated. - CS. ------------------- # For EL5 virtual machines, Append the

Actually your Syslinux config is less relevant than the kernel config file. Indeed Syslinux infers the method to use from the kernel image itself. I assume the .config is public. I will take a look as soon as I can Thomas Le 04/08/2015 14:09, intrigeri via Syslinux a ?crit : > Thomas Letan via Syslinux wrote (04 Aug 2015 09:27:38 GMT) : >> Are you using EFI Handover Protocol? >

Hi there!! I has been modified the syslinux.cfg file according to the rules to add some boot parameters but since this modification, every time I that I highlight the modified entry in the boot menu and hit the TAB button on my keyboard, the entry's boot parameters is displayed twice and when I try to "backspace" them out, the line again get displayed twice and so on. So my

Dear, "Xenoppix-x86-64(Xen3.0.2+KNOPPIX-x86_64-5.0.1) CD size" is released. http://unit.aist.go.jp/itri/knoppix/xen/index-en.html Xenoppix-x86-64 exploits latest CPU (Intel Core2 Duo and AMD Athlon64). * Xenoppix-x86-64 boots both X86 and X86_64 linux kernel on HVM of Xen. * Xenoppix-x86-64 looks like KNOPPIX but all packages are replaced for X86_64. * Xenoppix-x86-64 also

Lguest currently requires a TSC, which breaks older machines and Matt Mackall who boots the host with "notsc". In addition, there is no good solution to changing TSC speeds (informing all the guests about the TSC impending change before it happens would be a great deal of code and have issues with disobedient guests). This patch makes the host determine if the TSC is both constant and

I have used samba for nearly 9 years with no problems and we have about 20 users. In the past we have had a dedicated samba server. We have recently virtualized this server to a quad core Q6600 using vmware virtual server 1.0.4 on a 64 bit host running ubuntu 7.10. As part of the virtualization I installed samba 3.0.26a in ubuntu 7.10. Since this has happened users have complained about

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

First let me say that I'm not a sysadmin, but am simply wearing that hat this week so please excuse my ignorance. I need to temporarily move some virtual servers from a CentOS-KVM platform to a CentOS-XEN platform while I do some upgrades to the CentOS box. I've created a local LV, and used DD and SCP to transfer the block device from the VKM machine to the XEN machine. For quite a

Stan, Thanks for the reply. In our case we have actually already done most of the work you suggested to no avail. We had rebuilt two new ntp servers that sync against two stratum 1 sources, and all our nfs clients, regardless of using dovecot, sync to those two machines. You bring up the difference between bare metal and hypervisor, and we are running these machines on vmware 4.0. All the

TSC and Power Management Events on AMD Processors - Nov 2, 2005 - Rich Brunner, AMD Fellow Current AMD Opteron(tm) and Athlon(tm)64 processors provide power management mechanisms that independently adjust the performance state ("P-state") and power state ("C-state") of the processor[1][2]; these state changes can affect a

Hi, I am trying to boot Xen on top of a simulator. I am having problems with the APIC module in my simulator, not related to Xen. So, I want to boot Xen without APIC support. Is there a way to disable APIC support in Xen? I am fine even Xen is restricted to uni-processor environment. Thanks, Bhaskar _______________________________________________ Xen-users mailing list

Hi, I am running CentOS 5.3 32bit as a VirtualBox 3.0.0 guest running on Windows XP. The Windows host CPU usage is constantly at 50% although the CentOS guest is completely idle (i.e. 0.00 load average). I know this is a common problem related to the 1000Hz frequency that the CentOS kernel runs at. With previous versions of CentOS, I used the kernel-vm package [1] and it solved my problem.
