含有多个设备的GPU常见型号：Quadro RTX 6000/8000 简述系统内lspci查看显卡信息如下，可以看到同一个PCI插槽上（b1）包含了4个设备：VGA compatible、Audio device、USB、Serial bus，同时4个设备对应的驱动各不相同。 目前cyborg暂不支持此类加速设备的管理，cyborg采集的attach handle info中，只包含了function 0，即生成的xml中仅会透传GPU中的1个设备进入虚机，由于设备不完整，会导致libvirt会无法拉起虚机。 使用此类GPU，需要通过nova compute的PCI透传功能实现，总体思路如下： 切换GPU卡各类设备的驱动为vfio_pci。 透传GPU卡的所有设备至虚机。 若这两点有一点不满足，libvirt在拉起虚机时均会报如下报错： 123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646 ...

Generic Scaling GovernorsCPUFreq provides generic scaling governors that can be used with all scaling drivers. As stated before, each of them implements a single, possibly parametrized, performance scaling algorithm. Scaling governors are attached to policy objects and different policy objects can be handled by different scaling governors at the same time (although that may lead to suboptimal results in some cases). The scaling governor for a given policy object can be changed at any time with t ...

IntroductionPercona XtraDB Cluster is a fully open-source high-availability solution for MySQL. It integrates Percona Server and Percona XtraBackup with the Galera library to enable synchronous multi-source replication. A cluster consists of nodes, where each node contains the same set of data synchronized accross nodes. The recommended configuration is to have at least 3 nodes, but you can have 2 nodes as well. Each node is a regular MySQL Server instance (for example, Percona Server). You can ...
