similar to: Xen guests clock is exactly 2 hours before dom0 time

Dear List, I need to make an Aladdin eToken Pro visible in a Linux guest HVM, but I cannot assign the device to any domU, while it''s being blocked by the dom0. To avoid this trouble I would like to pass the whole USB bus to the domU directly, via PCI passthrough. Now I use xen 3.3.0 from xensource and xen kernel from Ubuntu 8.04 2.6.24-19-xen, because the xensource xen kernel

Hello, I''m hiring a XEN virtual machine running Ubuntu at a hosting company. My XEN virtual machine is hosted on a server which has some other VM''s running on it. They all use ubuntu or debian. After a crash sometime last week, the systemclock of my VM is off by an hour (it says 19:49, although it''s 18:49 here now). The other VM''s don''t have

Hey, I have rather new installation of xen, dom0 is running ntpd and is perfectly in time. All domU''s are ~23s in future. Running ntpd on the domU''s seem to have no effect, /proc/sys/xen/independent_wallclock appears to have no effect. I''m running xen-unstable and 2.6.16-rc4 in AMD64 box. Any tip would be appricated. Thanks, -- ++ytti

1. Shouldn''t the GPLPV drivers take care of the (bad) clock drift I''m experiencing in my Windows XP HVM? Or is there some other way around this problem that I haven''t been able to find on Google? How can I tell if the GPLPV drivers are active? I''ve added the /gplpv switch to the boot.ini file and the virtual NIC is definitely using the GPLPV version but other

Hello ! Just a quick question about time synchronization between xen dom0 and domUs... We''re running Xen 3.1 64-bit, with 32 and 64 bits linux guests. It''s up since 89 days and the domU''s time is around 5 minutes behind the dom0, which is updated via ntpdate... Any idea why it doesn''t sync the guests even that /proc/sys/xen/independent_wallclock is 0 ?

This must be documented somewhare but I checked the Xen 3.0 manual and the word "clock" doesn''t even exist in it. I checked the FAQ as well. I am running Xen 3.0.1 and an AMD64 CPU. I found that DOMUs time clock drifts ahead. I installed ntpdate and it reports to change the time but it does not. David _______________________________________________ Xen-users mailing list

I don''t want my dom0 to update the clock in my HVM domU. I''ve already disabled network-based time synchronization inside the HVM. I''ve tried setting /proc/sys/xen/independent_wallclock=1 and then restarting xend, but the guest still gets the correct time. Any ideas on how to accomplish this?

Hi all, where can I set the date in domU. ''ntpdate -u ...'' works but dosn''t set the date. date MMDDhhmm has also no effect. What can I do? -- cu Roland Kruggel  mailto: rk-liste@gmx.de System: Intel 3.2Ghz, Debian etch, 2.6.15, KDE 3.4 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

The time appears to be perfect inside dom0, however all the domU''s tend to have a slightly faster date which gets further out of sync every day. I''m currently using Xen 3.0.3 with Gentoo Linux, under 3.0.2 I had no problems with domU clocks. Are there any known issues which could cause this? I''d strongly prefer not to run ntpd in every domU, having all domU clocks in

While in the upstream kernel I''m unable to find any use of XENPF_settime (and the DOM0_SETTIME alias of it) at all, in the 2.6.18 tree (and the forward ports of it) the function gets used only when ntp_synced() returns true (and - that''s minor - when independent_wallclock is not set). It would however seem to me that this doesn''t cover the case where the host clock gets

Hello, On a xenserver with several (39) domUs, we experience problems with the system clock of the domUs. The clock seems to drift away several seconds up to two minutes from the dom0 clock. We do have set independent_wallclock=0. According to the docs (i.e. http://wiki.xensource.com/xenwiki/InstallationNotes) that way domUs should use the dom0 clock, but apparently that''s not the case.

Hi everybody! I know this is an ultraknown issue, but in my case i think it is going beyond. As you may guess my domUs clocks go faster or slower They come with the same OS (Centos 5 2.6.18-92.1.18.el5 ) but each of them have a different clock speed. Why? Dom0 does not syncronize domUs : So i watched out looking for any solution.... First attempt: /proc/sys/xen/independent_wallclock = 0

Since upgrading to b129, I''ve noticed that my system clock is ahead by five hours, exactly how much I am behind UTC (US Eastern Time). The strange thing is it only happens when I have xen enabled. If I ''svcadm disable milestone/xvm; reboot'' the clock is correct again. If I correct the time manually, ntp knocks it right back ahead again. Oddly enough, even ntp knows

QUESTION: Is there a way of passing arguments from an external file to a script so that they can be used directly by functions within the script? I have a series of interdependent functions. I wish to test the time for processing various datasets. I was initially doing something along the lines of the following (yes, I am new to R): rm(list= ls())

Is there a package to do this? Normally the hardware clock is set during shutdown if one is running ntpd. But if a long-running server shuts down unexpectedly, this isn't done, and the hardware clock might be off by a lot when it comes back up. So setting it periodically from a cron job could be useful. What do others do? Adding a one liner to /etc/cron.daily that invokes

Hi list, I have a problem with this stuff, i read many documents about it but i would like to know if anyone have got to resolve the problem. The point is that my vm has the clock unsynchronize, i tried many things and it seems that its work fine but im not sure. Now im using ntpd to synchronize the time but im not trust on it because it didnt work before. First, i tried the jiffies on

I have numerous problems with my para- and hardware- virtualizated guests. Clock in guests drifts up to many days. Sometimes it happens after xendomains service saves and restores state on reboot, sometimes not, sometimes it happens when I am sleeping :). I use latest fedora 8 with latest updates (I have had problem since fedora 6 ...) My proc settings: /proc/sys/xen/permitted_clock_jitter is

Hi, using SLES10 I''m unable to synchronize the time of DomU with that of Dom0. There is a persistent offset of about 3 seconds!

Hello techs, We used XL toolkit for Xen hypervisor for starting Windows hvm VMs and the option rtc_timeoffset worked perfectly with XL. It helped us to set correct Timezone time/offset for Windows HVM VMs from inside virtual_machine xen config. For example: Below option WORKS perfectly with XL toolkit. [root@hw12xen ~]# cat goillltawdlssq.xl.cfg | grep offset rtc_timeoffset = "7200"
