Abstract: Embodiments provide a resource management technology that may be applied to a host, where the host includes a CPU, an endpoint connected to the CPU, and an I/O device connected to the endpoint. A method includes: allocating, by the CPU, a target endpoint to a target process, where a virtual device is disposed on the target endpoint; obtaining, by the target endpoint, a performance specification of the target process, and adjusting a performance parameter of the virtual device according to the performance specification, where the adjusted virtual device satisfies a total requirement of performance specifications of all processes that use the target endpoint; and when the target process needs to access a resource, obtaining, from the I/O device, a resource that satisfies the performance specification of the target process, and providing the obtained resource to the target process for use.

Abstract: A method for backing up data in a data center, device and system are provided. The data in all the VMs of one data center can be backed up simultaneously, and the associations between the VMs are also backed up during the backup, so it is unnecessary to concern the recovery orders of the VMs when the data of the data center is recovered. Meanwhile, when the stored data is exported from the hypervisor node, it is unnecessary to notify the upper layer OS for a backup, thereby improving the data backup efficiency and reducing the system logical complexity.

Abstract translation: 提供了一种在数据中心，设备和系统中备份数据的方法。 一个数据中心的所有VM中的数据可以同时进行备份，并且在备份期间也备份VM之间的关联，因此当数据中心的数据为 恢复。 同时，当从管理程序节点导出存储的数据时，不需要通知上层OS进行备份，从而提​​高数据备份效率，降低系统逻辑复杂度。

Abstract: A packet processing method in a computing system is disclosed. The computing system comprises a host, wherein at least one network interface card is connected to the host. The network interface card includes switching equipment and at least two network ports. A first network port is corresponding to at least one physical function PF and multiple virtual functions VFs. At least one VF of the first network port is provided for a first virtual machine on the host in a passthrough manner. The first virtual machine sends a data packet from the VF that is connected to the first virtual machine. Switching equipment of the first network port forwards the data packet according to a destination MAC address of the data packet, and sends the data packet to a virtual bridge on VMM of the host. The VMM provides abundant network function processing for the data packet.
