Hi techs, Could you please explain or refer me to documentation where I could find a description of global_quota schedinfo option. Someone told me that it could mean a cpu limitation in percents like: global_quota : 25000 (does it mean cpu limit % set to 25 ?)
Is it true? What other parameters mean in below output? I didn't find any related documentation at libvirt.org. Could you help me to describe me or refer to some description what below schedinfo options mean? Thanks.
