FreeBSD 6.0 on VMware Server Time and Clock Slow Down FreeBSD 6.0 sa VMware server oras at orasan bumagal

FreeBSD 6.0, when running as guest operating system in VMware Server or VMware Workstation 5.0, the FreeBSD system encounters considerable clock ticking slowdown, up to as high as 60% of time loss compared to real time clock. FreeBSD 6.0, kapag tumatakbo bilang panauhin ng operating system sa VMware Server o VMware Workstation 5.0, ang FreeBSD sistema encounters marami orasan gris paghina, hanggang sa mataas na bilang na 60% ng oras pagkawala kumpara sa real-time clock. Even right after you reset the clock and set the time properly, after a while, the gap between FreeBSD virtual machine time and actual time will be widen. Kahit na karapatan pagkatapos i-reset mo ang orasan at itakda ang oras ng maayos, pagkatapos ng isang habang, ang puwang sa pagitan ng FreeBSD virtual machine oras at aktwal na oras ay lumawak.

One possible solution or workaround to this problem is to disable the use of APIC (note: Not ACPI) by adding the following line in /boot/loader.conf: Isa o workaround posibleng solusyon sa problemang ito ay upang huwag paganahin ang paggamit ng APIC (tandaan: Hindi ACPI) sa pamamagitan ng pagdagdag ng mga sumusunod na linya sa / boot / loader.conf:

hint.apic.0.disabled=1 hint.apic.0.disabled = 1

By disabling APIC device, FreeBSD is forced to fall back on the IRQ timers to avoid the rate of the clock and timer on emulated FreeBSD machine on VMware slows down. Sa pamamagitan ng hindi APIC aparato, FreeBSD ay sapilitang sa umasa sa ang irq timers upang maiwasan ang mga rate ng orasan at timer sa emulated FreeBSD makina sa VMware slows down. The down side to this resolution is that FreeBSD cannot runs in as SMP kernel mode as a virtual SMP machine on the emulated machine. Ang down side sa resolution na ito ay na FreeBSD ay hindi tumatakbo sa bilang SMP kernel mode bilang isang virtual SMP makina sa emulated makina.

Another alternative is to comment out the “device apic” line in the kernel config file and rebuild the kernel, but only if you are technically know what you’re doing. Isa pang alternatibo ay ang puna ng mga "aparato apic" linya sa kernel config file at muling itayo ang kernel, ngunit lamang kung ikaw ay technically kung ano ang ginagawa mo.

For VMware host in Windows NT operating system, reboot and run the Windows OS in safe mode may solve the timing incorrect issue too, although it’s better to format and install the whole machine as FreeBSD rather than running it as Windows safe mode host. Para sa VMware-host sa Windows NT operating system, reboot at patakbuhin ang Windows OS sa ligtas na mode ay maaaring malutas ang mga isyu na masyadong timing hindi tama, kahit na ito ay mas mahusay sa format at i-install ang buong makina bilang FreeBSD sa halip na tumatakbo ito ng Windows bilang ligtas na mode host.

    [...] ;umm, seems that I am little bit enthusiastic about knowing all those unix-like system recently, since I didn’t pay ;much time to know ;them before. [...]; Umm, tila na ako ay maliit bit masigasig tungkol sa mga alam ng lahat ng mga utak-tulad ng sistema ng kamakailan-lamang, dahil ako ay hindi magbabayad; maraming oras upang malaman; ang mga ito bago. right now I’ve set up ;3 VMs with vmware‘>CentOS4.4 , Gentoo Linux 2006 ;(since it is able to run in Sun SPARC machine), FreeBSD 6.1 , and going to setup one more VM with Sun Solaris 10 x86 (11/2006 version) ;arch to get familiar with all those main stream unix-like OSes.while toying around with Gentoo and FreeBSD, I did found that Gentoo seems had no problems on the clock issue happened in my CentOS as well as FC6 as described in my previous post. ngayon ko na-set up; 3 VMS sa vmware '> CentOS4.4, Gentoo Linux 2006; (dahil ito ay able sa tumakbo sa Sun SPARC makina), FreeBSD 6.1, at pagpunta sa setup ng isang mas VM sa Sun Solaris 10 x86 (11/2006 bersyon); arko upang makakuha ng pamilyar sa lahat ng mga main-stream ng utak-like OSes.while landi sa paligid sa Gentoo at FreeBSD, ako ay natagpuan na ang Gentoo had tila walang problema sa orasan isyu na nangyari sa aking CentOS pati na rin ang FC6 tulad ng inilarawan sa aking nakaraang post. but FreeBSD did encounter this problem again. ngunit FreeBSD ay magkasalubong ang problemang ito muli. the clock is much slower than real one on the host OS.by searching to Google, I found this post saying about FreeBSD clock is slowing when acting in VMWare as guest OS, and it was also the same reason in Linux that the OS is using APIC to get the clock for the time. ang relos ay marami mabagal kaysa sa tunay na isa sa host OS.by paghahanap sa Google, natagpuan ko ang post na ito sinasabi tungkol sa FreeBSD orasan ang slowing kapag kumikilos sa VMWare bilang panauhin OS, at ito ay din sa parehong dahilan sa Linux na ang OS ay gumagamit ng APIC upang makakuha ng orasan para sa oras. the solution is to disable APIC on the boot time by editing /boot/loader.conf and put a line:hint.apic.0.disabled=1in the file and reboot FreeBSD, or to ;’to comment out the “device apic” line in the kernel config file and rebuild the kernel’. ang solusyon ay na-disable APIC sa boot oras sa pamamagitan ng e-edit ng / boot / loader.conf at ilagay sa isang linya: hint.apic.0.disabled = 1in ang file at reboot FreeBSD, o sa; 'sa comment ang mga "aparato apic" linya sa kernel config file at muling itayo ang kernel '. also by doing so will loose the ability for the guest OS to run in SMP mode. din sa pamamagitan ng paggawa nito ay maluwag ang kakayahan para sa mga bisita ng OS na tumakbo sa SMP mode. pretty same as what ;happened in Linux. pretty katulad ng kung ano; nangyari sa Linux. After doing the loader.conf modification and reboot the FreeBSD VM, the clock is back to normal without problem. Pagkatapos ng paggawa ng mga pagbabago at loader.conf reboot ang FreeBSD VM, ang orasan ay bumalik sa normal na walang problema. by installing VMWare-Tools into FreeBSD vm, verifying that vmware-guestd is running and also in the FreeBSD guest OS’s .vmx file, set toos.syncTime to TRUE, the time in my FreeBSD vm is back to normal and won’t need NTP to sync the real time, just like what I did in my CentOS in previous post. sa pamamagitan ng pag-install VMWare-Kasangkapan sa FreeBSD vm, pagpapatunay na vmware-ay tumatakbo at guestd din sa mga bisitang FreeBSD OS's. vmx file, i-set toos.syncTime sa true, ang oras sa aking FreeBSD vm ay bumalik sa normal at hindi kailangan NTP sa sync ang real-time, tulad ng kung ano ako did sa aking CentOS sa nakaraang post. It’s pretty cool that I can run all those 3 VMs with different unix-like OSes simutaniously in my Windows 2003 R2 Server with 2GB RAM. It's pretty cool na ako maaari tumakbo ang lahat ng mga 3 VMS na may iba't-ibang utak-like OSes simutaniously sa aking Windows 2003 Server R2 sa 2GB RAM. I gave ;each guest OS 384mb RAM to run and thanks to VMWare Workstation’s dynamic memory allocation technology, while my testing of those 3 VMs I can still have more than 1 gb RAM for my host OS. I gave; bawat bisita OS 384mb RAM na tumakbo at salamat sa VMWare Workstation's dynamic memory allocation teknolohiya, habang ang aking mga pagsubok ng mga 3 VMS ako ay maaari pa ring magkaroon ng higit sa 1 gb RAM para sa aking host OS. I think it should be no problem for me to boot up one more Solaris 10 VM in the same time. Ako isipin ito ay dapat na walang problema para sa akin sa boot up ng isang mas Solaris 10 VM sa parehong oras. The goal is to understanding all those system and networking administration tasks on those different main-stream unix-like OSes and further more to host web applications and database systems on them. Ang layunin ay ang unawa sa lahat ng mga networking system at pangangasiwa sa mga gawain sa iba't-ibang mga main-stream ng utak-like OSes at karagdagang more na mag-host ng web application at database systems sa kanila. maybe than trying to develop some Mono projects ;to run ASP.NET websites ;upon them. siguro kaysa sa sinusubukan mong bumuo ng Mono ilang mga proyekto; na tumakbo ASP.NET website; sa kanila. ;I’ve already found that it’s pretty different on the admin of ; Linux and BSD systems since it’s pretty different on the directory structures as well as those admin commands and locations of various config files. ; Ko na nahanap na ito ay medyo sa iba't-ibang mga admin ng; Linux at BSD system dahil ito ay mainam sa iba't-ibang ang direktoryo ng estraktura pati na rin ang mga admin command at lokasyon ng iba't-ibang config file. wondering if it’s also different ;in a Solaris OS… anyway, it’s always nice to learn new things, and I am enjoying it on my weekend… Technorati Tags: linux ;, ;freebsd, ;solaris, ;CentOS, ;ntp, ;clock, ;kernel , ;vmware, ;APIC ; [...] nagtataka kung ito ay din ng iba't-ibang mga; sa isang Solaris OS ... anyway, ito ay palaging nice upang malaman ang mga bagong bagay-bagay, at I am enjoying ito sa aking weekend ...
