How to configure time on virtual clients using KVM?
by Theo Band 28 Jun '12

28 Jun '12

I use a CentOS5.8 server with KVM. I have several virtual machines running on it. When I reboot the server (takes 10 minutes) all VMs are saved and correctly restored. The time on the clients is however of by 10 minutes. nptd is running on the clients and that is able to correct this big mismatch. But what I don't understand is that the host does not seem to help the client with it's timekeeping. On a fedora16 machine I can tell that kvm-clock is being used: cat /sys/devices/system/clocksource/clocksource0/available_clocksource kvm-clock tsc acpi_pm cat /sys/devices/system/clocksource/clocksource0/current_clocksource kvm-clock One the centos5 client I can think I see the same: dmesg|grep time.c time.c: Using 1.193182 MHz WALL KVM GTOD KVM timer. If I suspend a client, I see the time is correct just after resume. If I save and restore the time is left at the saved time: ssh valk5 date;virsh save valk5 /var/lib/libvirt/images/save ;sleep 60;virsh restore /var/lib/libvirt/images/save;ssh valk5 date;date Thu Jun 28 18:37:59 CEST 2012 Domain valk5 saved to /var/lib/libvirt/images/save Domain restored from /var/lib/libvirt/images/save Thu Jun 28 18:40:00 CEST 2012 Thu Jun 28 18:41:07 CEST 2012 So my question is, is this intended behaviour? Is there something I can change to kick the time during a restore? A second related question is what happens after a live migrate. I can migrate the VMs to a different machine, but that machine has slightly different specs. I notice that the clock speed is really off (minutes per hour need to be corrected after a live migrate). I guess the client gets a differt CPU clock on the other host. Is there a way to update the client without a reboot? A reboot helps, so I guess some timer calibration takes place then. But that defeats the purpose of a live migrate. Theo

Strange du/df behaviour.

unixODBC Centos 5 Testing version
by Tom Bishop 27 Jun '12

27 Jun '12

Trying to get a later version of the unixODBC RPM that is in Centos 5, I read in some posting that unixODBC.x86_64 2.2.12-1.el5s2 was in the testing repo but I was unable to locate it, currently it appears that we are runningunixODBC-2.2.11-7.1. I have looked in the Centos 5 Testing repo but do not see the 2.2.12 version....anyone have any pointers to move me along, thanks.

Can you please correct me. Thank you

dhclient-eth0.conf question
by Jerry Geis 27 Jun '12

27 Jun '12

I have the line: request tftp-server-name; in my centos 6.2 dhclient-eth0.conf file If the tftp-server-name is given by the DHCP server everything is fine. however, if it is NOT given the client seems to error out and does not get an address and is not on the network. I then take the line out and do service network restart and it works just fine. How can I make this an optional thing? If the server can provide it fine if not thats fine and just keep going? How do I do that? Thanks, Jerry

XFS-in-a-file
by Boris Epstein 27 Jun '12

27 Jun '12

Hello listmates, Has anybody attempted to run an XFS in a file mounted via -o loop? The file size is about 20 TB and it resides in a larger XFS filesystem residing on a disk. That filesystem's size is about 25 TB. What sort of degradation should one expect under that sort of scenario? The reason I am asking is that I am trying to run a MooseFS chunkserver in that filesystem-in-a-file and looks like I am getting some pretty bad delays. Thanks. Boris.
