Abstract
In one example control method, a first virtual machine and a virtual machine management system run on a host system. The first virtual machine is directly connected to a network interface card system, and the first virtual machine performs stateful service interaction through the network interface card system. The host system applies for memory space of a first physical area address to store service interaction status information of the first virtual machine, and the first physical area address has a non-writable attribute for the first virtual machine. The virtual machine management system sends first indication information to the network interface card system to indicate an identifier of the first virtual machine and the first physical area address.
Claims20
A network interface card system control method, wherein the control method comprises:
- receiving first indication information, wherein the first indication information indicates an identifier of a first virtual machine and a first physical area address, wherein the first virtual machine runs on a host system, wherein the first physical area address is a storage address in physical pages in a host storage of the host system, wherein the first physical area address is used to store first entry data, wherein the first physical area address has a non-writable attribute for the first virtual machine, and wherein the first entry data comprises service interaction status information of the first virtual machine;
- and
- storing the first indication information.
A control method, wherein a host system comprises a host processor and a host storage, wherein a first virtual machine and a virtual machine management system run on the host processor, wherein the control method is based on the host processor, and wherein the control method comprises:
- applying to the host storage for a first physical area address in physical pages, wherein the first physical area address is used to store first entry data, wherein the first physical area address has a non-writable attribute for the first virtual machine, and wherein the first entry data comprises service interaction status information of the first virtual machine;
- and
- sending first indication information to a network interface card system through the virtual machine management system, wherein the first indication information indicates an identifier of the first virtual machine and the first physical area address.
A network interface card system, wherein the network interface card system comprises a network interface card processor and an interface receiving programming instructions, and wherein the network interface card processor executes the programming instructions to:
- input a first indication information through the interface, wherein the first indication information indicates an identifier of a first virtual machine and a first physical area address, wherein the first virtual machine runs on a host system, wherein the first physical area address is a storage address in physical pages in a host storage of the host system, wherein the first physical area address is used to store first entry data, wherein the first physical area address has a non-writable attribute for the first virtual machine, and wherein the first entry data comprises service interaction status information of the first virtual machine;
- and
- store the first indication information.
A host system, wherein the host system comprises a host processor and a host storage, wherein a first virtual machine and a virtual machine management system run on the host processor, and wherein the host processor executes programming instructions to:
- apply to the host storage for a first physical area address in physical pages, wherein the first physical area address is used to store first entry data, wherein the first physical area address has a non-writable attribute for the first virtual machine, and wherein the first entry data comprises service interaction status information of the first virtual machine;
- and
- send first indication information to a network interface card system through the virtual machine management system, wherein the first indication information indicates an identifier of the first virtual machine and the first physical area address.
