Chapter 4. Additional Configuration
4.1. Configuring Operating Systems with osinfo
Red Hat Virtualization stores operating system configurations for virtual machines in /etc/ovirt-engine/osinfo.conf.d/00-defaults.properties. This file contains default values such as os.other.devices.display.protocols.value = spice/qxl,vnc/vga,vnc/qxl.
There are only a limited number of scenarios in which you would change these values:
- Adding an operating system that does not appear in the list of supported guest operating systems
-
Adding a product key (for example,
os.windows_10x64.productKey.value =) -
Configuring the
syspreppath for a Windows virtual machine (for example,os.windows_10x64.sysprepPath.value = ${ENGINE_USR}/conf/sysprep/sysprep.w10x64)
Do not edit the actual 00-defaults.properties file. Changes will be overwritten if you upgrade or restore the Manager.
Do not change values that come directly from the operating system or the Manager, such as maximum memory size.
To change the operating system configurations, create an override file in /etc/ovirt-engine/osinfo.conf.d/. The file name must begin with a value greater than 00, so that the file appears after /etc/ovirt-engine/osinfo.conf.d/00-defaults.properties, and ends with the extension, .properties.
For example, 10-productkeys.properties overrides the default file, 00-defaults.properties. The last file in the file list has precedence over earlier files.
For virtual machines with Windows Server 2016, on each RHV host, modify the /etc/modprobe.d/kvm.conf configuration file by adding the line: options kvm ignore_msrs=1
