Dear list(s), we are running a cluster of virtual machines on ganeti 2.15.2 on top of qemu-kvm 2.1.2. Hosts are Debian jessie (Kernel 3.16). We have big trouble with timekeeping on guests, no matter if these guests are lenny, squeeze, wheezy or jessie. Clock drifts heavily on some, others are fine. There is no obvious pattern on which guest this happens and on which not, but it seems the clock

Hi, I have a dual core athlon server and it is gaining 1 day every 2 days w/o time sync. Even with ntpd running, the time is not under control. I must put a very frequent cronjob of 'ntpdate' to keep the time under control. This creates big problems since winbind eventually stops working so my users can't access their data. Any ideas? -- Ugo -> Please don't send a copy of

Hi, I've noticed that one of my new servers (new mobo) if drifting slowly backwards in time (in aprox. 24 hours, system time drifts back 5 minutes). I have an ntpd process which is supposed to sync with a lan time server but it's not quite working. So I'm launching a manual ntpdate or ntp-client once an hour and that seems to work. However, suppose I update system time at every hour

Hi, We have a little over 100 servers, almost all running CentOS 5.7. Virtually all are Dell servers, generally a mix of 1950s, R610s, and R410s. We use NTP and/or PTP to sync their clocks. One phenomenon we've noticed is that (1) on reboot, the clocks are all greatly out of sync, and (2) if the PTP or NTP process is stopped, the clocks start drifting very quickly. If it was isolated to

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.

I just finished going through the time sync problem, and here's the info I used: To configure ESX 2.5.x Server: http://tinyurl.com/ycpcfv <http://tinyurl.com/ycpcfv> To configure Windows Guest OS: http://tinyurl.com/yctxrr <http://tinyurl.com/yctxrr> To configure CentOS w/o X installed, you still need to install the vmware tools.

I had my eye on the Tyan dual-Opteron mobos for awhile. I tried to find a posting *anywhere* sharing experiences with these boards under Linux. No such luck. So placing myself under the heading "Where Angles Fear to Tread," I went ahead and built a system anyway. Here's what I've learned. The specs: Tyan Thunder K8SE S2892, BIOS 1.01 2x Opteron 270, 2Ghz Dual-Core, retail

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

Hello, I am currently attempting to run some windows games through wine, specifically Fable - The Lost Chapters and The Elder Scrolls III - Morrowind and I am experiencing problems with my cursor drifting during game play. When I start the game (as soon as the menu screen) the mouse is initially stable, but after I move the mouse it will begin to drift vertically down at a constant speed

A couple of months ago I reported some problems with a batch of Tyan K8SSA (S3870) based machines. We are continuing to have an odd problem with these boxes, and if anyone has seen something similar elsewhere, I'd appreciate hearing about it. These boxes are running Centos 4.4 x86_64 with kernel 2.6.9-42.0.3.ELsmp. They are dual Opteron 265's (dual core) with 4x2GB DIMM's. The

We have been seeing failures with CentOS 4.4 i386 (not x86_64) running compute-intensive programs on Tyan K8SRE (S2891) Tymotherboards, running Opteron 265's. This motherboard is used in the Tyan barebones box GT24 (B2881). We have these boards populated with 8GB of RAM, consisting of mixed 2GB and 1GB sticks. The symptom is that CPU-bound programs (may or may not be related to floating

HI All, I have a dilemma and I would appreciate advice 1. Get a good size case, mobo, processor, etc and put 8 hard drives it in and RAID them. (yes an 8 port SATA mobo). Running CentOS. or 2. Get an eSATA enclosure that has room for 8 or 10 drives and just connect it to box? I know that RAID is not a full proof backup, but I am looking for a solution to store all of my data, projects, music,

Does anyone have any experience with Super-Micro brand motherboards // dual Xeon cpu's? Had to swap out my Tyan piece of junk and going back with the S-M board. I believe it has similar north/southbridge chips on it -- at least they are the intel MCH ICH5R and PXH plus the 82546GB. One area that the Tyan board was seriously lacking in was in the hardware monitoring department. The S-M

Hi- I'm looking for an appropriate system board to power a system with two (2) Digium TE410P cards. Since these cards require the 3.3 volt PCI, I'm considering vendors like Tyan for the motherboard. Can anyone please tell me their experiences with the Tyan i7501 series (Xeon-basd), or recommend an alternate motherboard? Thanks Scott Scott M. Stingel Emerging Voice Technology Inc.

Was wondering if anyone has any luck with the Tyan s4985 motherboard, I had loaded up the latest 5.4 release and in installed most everything that I wanted but when I loaded it up, as in processor wise it would lock up. Funny thing I could still ssh to it but not do a su - or anything from the console. I think it is kernel related and tried the previous kernel but it still exhibited the same

I am trying to install CentOS to a server that has a Tyan S2891 motherboard, 2 Opteron 875 Dual Cores and 2GB of RAM. I have been able trying to install over a network but the tg3 driver will not load. I then installed from a DVD and on rebooting after the installation I cannot get the network drivers to load and the RAID controller in the PCI slot is not available. It seems that when I do an

I've been planning to build a dual Opteron server for awhile. I'd like to get people's suggestions on a suitable motherboard. I've looked at the Tyan K8SE (S2892) and K8SRE (S2891) but would like to find more Linux-specific experiences with these boards. Some features I expect are at least 4 SATA (SATA-300?) ports, serial console support in the BIOS, USB 2.0 and IEEE-1394
