similar to: date in domU

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 ?

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

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

Hallo, at first, sorry for my bad english. I have a big problem. I have xen 3.0.1 running. I have 4 domU. One domU is hosting a dns-server. All runns fine. Yesterday i have updated to 3.0.2. Sorce from the tar file. Build a new kernel and reboot the system. It''s running. But i have one problem. The dns resolving runns not fine. Is there any changes for the dns between 3.0.1 and

Hi all, I''m experiencing problems with time: after I sync time both into dom0 and dom1 with public ntp servers, times are not the same. Do you have the same problem?

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

Hi, I would like to sync my CentOS 6.3 hardware clock time to my NTP server's time. Can I do that without reboot the hosts? If yes, it would be great if anyone of you can provide me steps to do that. I am newbie in CentOS. Thanks, Anand Singh

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!

Hallo, I''m running Xen 3 (xen-unstable tarball from 4/27) with kernel 2.6.16   and Debian Etch in all domains. Most things seem to work very well. But I have some problems with NFS in domU. The NFS-Server started at boot time but I cant''t access to the shares from a client. --> sigma:~# showmount -a xen-samba rpc mount dump: RPC: Unable to receive; errno = Connection

This is really stupid question. But referring to: http://lists.centos.org/pipermail/centos/2009-October/083791.html I don't see any line related to ntpd in my /var/log/messages . Do I need to turn-on ntpd for timekeeping on VMs? Some people say not to use ntpd on VMs for timekeeping or is it ntpdate cron job? Can someone please elaborate on this? Thanks, Jonathan. -------------- next part

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

I think it''s perfect the way it is. Run NTP in dom0, all the domU''s then have synchronized time. I can still set timezones on all of these boxes independantly. Timezone has nothing to do with NTP synchronization. Tim:> > yeah, i''m already doing that, I was just saying, it *seemed* > like they were getting their time from domain0, and weren''t >

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 Andrew, what is it for? I got a revision_match_error. Could this be the reason why my windows clients can't sync the time via nt5ds? How can I solve this? Regards Tim Am 28.

Hi all, finally I have managed to upgrade to Xen 4.0 (actually it reports Xen 4.1-unstable) and Debian''s Linux kernel 2.6.32-4-xen-amd64. Now I am wondering what happend to independent_wallclock. There is no more /sys/xen and sysctl complains error: "xen.independent_wallclock" is an unknown key Does anybody know more about this? Thanks + best regards, Stephan

I''ve got two tables set up - Things and Users where Users have many things and Things belongs to Users. They''re connected by Things.user_id => User.id and Things.updated_by_id => User.id both in the Things model using Belongs_to and custom foreign key for one of them. Problem is when I''ve got the updated_by_id belongs_to I can''t add Things using

Package: xen Severity: important Version: 4.0.1-1 The Xen documentation and Xen Debian wiki describes using independent_wallclock to sync domU clocks against the dom0 clock http://docs.vmd.citrix.com/XenServer/4.0.1/guest/ch04s06.html http://wiki.debian.org/Xen#Possible_problems_and_bugs-1 This sysctl appears to have gone away with squeeze, but the documentation is not updated Time drift is

If I try: @article.article_groups.delete_if {|x| x.group_id == x.group_id } It does nothing. If I try: articletmp.article_groups.each{ |x| @article.article_groups.delete(y) } It deletes some of the groups. @article.article_groups.clear works. Why dosn''t the to first examples work as expected?? Do I have to put groups I don''t want to

Hi, I am facing problem in sync time within DomU with Dom0. After gone through mailing lists, I have set /proc/sys/xen/independent_wallclock to 0.
