After a couple of reboots ( too "cycle" trough the nics ) my configuration was correct, my etc/sysconfig/network-scripts/ifcfg-* files where all in order. ( with correct mac address ) But this file dont excist on any of my nodes: /etc/udev/rules.d/70-persistent-net.rules So i generated it with : echo add > /sys/class/net/eth0/uevent echo add > /sys/class/net/eth1/uevent echo add > /sys/class/net/eth2/uevent Reboot no difference. Tried: mount -o rw,remount / before all the changes also on my second run.. But the change is not persistent. Anything special i need to do to keep this file? /etc/udev/rules.d/70-persistent-net.rules Thanks for your time :) -Espen

[Users] Win VM java problem
by Nerijus Baliunas 06 Jun '12

06 Jun '12

Hello, I have a strange problem with Windows 2003 server VM - any java app hangs, and javaw.exe process takes 98% of cpu. Then I transfered VM image to another server, and here it works. Any idea what happens? Misbehaving server has Xeon 5110 1.60 GHz CPU (VM's System Properties shows it as Intel Celeron_4x0 (Conroe/Merom Class Core 2)) and ovirt 3.0.0, and a working server has Xeon E5620 2.40GHz CPU (Westmere E56xx/L56xx/X56xx (Nehalem-C)) and recent ovirt git snapshot (from May 30). Regards, Nerijus

[Users] Rebooting node causes re-arrange of nic interfaces.

Every time i reboot one of my nodes eth0 eth1 and eth2 gets re-arranged, this really messes with the network configuration. I am running the ovirt-node 2.3 iso image. I havent had this issue with earlier installs of debian/fedora etc. any way to fix this besides getting new hardware? Cheers Espen

Hi I am writing a small python script to get the name of all the VMs that matches a string. ========== import sys import getopt import optparse import os import time from ovirtsdk.api import API from ovirtsdk.xml import params URL='https://192.168.1.1:8443/api' #RHEVM API ACCESS URL USERNAME='admin@internal' PASSWORD='ovirt' api=API(url=URL, username=USERNAME, password=PASSWORD) vmnames = api.vms.list(query = 'name=a') print vmnames ========== Print output is, <ovirtsdk.infrastructure.brokers.VM object at 0x1d4e790> I was expecting a list of VMs which contains "a" in their names. Am I doing it correct? Can someone guide me with a small example? My reference is http://www.ovirt.org/wiki/SDK#Querying_collection_with_oVirt_search_engine_… Thanks, Anil
