Hi all, Recently I merged the os info [1] patches. Its main responsibility is to make our OS-bounded configuration file-based rather than combination of hard-coded enum (VmOsType) and db config values. What is there to configure? * available OS types - what you see in the drop-down selection for the os e.g os.RHEL6.name = Red Hat Enterprise Linux 6 * recommended min/max memory per os os.Unassigned.resources.maximum.ram.value = 64000 * supported network devices - this will actually set the drop-down of nic types in new Interface dialog os.Windows7.devices.network.value = rtl8139_pv, rtl8139, e1000, pv * compat version values os.Fedora12.devices.audio.value = ich6 os.Fedora12.devices.audio.value.3.2 = ac97 * inheritance - DRY :) os.RHEL5.derivedFrom.value = RHEL4 os.RHEL4.family = linux * cpu Arch - currently we support only x86 but this will come handy for supporting powerPC arch or arm etc after cross-matching with the cluster arch. os.Other.cpuArchetecture.value = x86 The file is located at /etc/ovirt-engine/osinfo.conf.d/00-osinfo-defaults.properties and is symlinked to /usr/share/ovirt-engine/conf/osinfo-defaults.properties If you want to overide the values or just add your setup more OSs just add 10-osinfo.properties under osinfo.conf.d Bare in mind, If you ever have to add logic against OSs pls don't add it to vdc_options. Use the osinfo instead. Cleanups from ConfigValues and vdc_options will soon follow as well as treatment for custom icon images for OSs. Thanks, Roy [1] http://www.ovirt.org/OS_info
