Detailed description of the invention
The core of the present invention is to provide a kind of virtualization implementation method based on SR_IOV, with realize improve virtual machine for
The serviceability of I/O.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with in the embodiment of the present invention
Accompanying drawing, is clearly and completely described the technical scheme in the embodiment of the present invention, it is clear that described embodiment is only
The a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under not making creative work premise, broadly falls into the scope of protection of the invention.
Refer to Fig. 1, Fig. 1 is a kind of virtualization implementation method flow chart based on SR_IOV provided by the present invention, should
Method is applied to virtualization system IncloudSphere, and the method includes:
S11: open IOMMU function or VT-D function in basic input-output system BIOS, and open in BIOS
Single input and output virtualization SR_IOV function；
S12: amendment kernel startup item, opens IOMMU function in kernel；
S13: distribute virtual functions VF for physical network card；
S14: VF is distributed to virtual machine and uses.
Visible, the method has carried out the realization of SR_IOV technology in IncloudSphere system, by SR_IOV technology
Make virtual machine can directly use physical network card, and multiple virtual machine shares physical resource by distribution VF, so makes
Obtain multiple virtual machines and can share the physical function of network interface card, even if obtaining multiple virtual machines can share same physical network card money
Source, improves the network interface card serviceability of virtual machine, improves the virtual machine serviceability for I/O simultaneously.
Based on said method, concrete, BIOS opens the process of IOMMU function or VT-D function particularly as follows: right
In the AMD processor of support SR_IOV, basic input-output system BIOS is opened IOMMU function；For supporting SR_IOV
Intel processor, in basic input-output system BIOS open VT-D function.
Wherein, step S12 process particularly as follows: in/etc/default/grub file with GRUB_CMDLINE_
LINUX is in the row started, for supporting Intel processor writing commands intel_iommu=on of SR_IOV, for supporting
AMD processor writing commands iommu=1 of SR_IOV.
Wherein, the process of step S13, particularly as follows: the SR_IOV function of configuration physical network card ethi, loads the physics of network interface card
The driving of function PF, configuration/sys/class/net/ethi/device/sriov_numfs file, write virtual functions VF's
Quantity, after write, the driving of unloading PF.
Further, when mac address is all 0 in VF, ip link set order is used to specify mac address.
Further, after VF distributes to virtual machine use, virsh createvmuuid.conf order is utilized to open
Virtual machine.
Wherein, IncloudSphere is for being responsible for virtual fusion, distribution according to need and the high-efficiency management of bottom physical resource.
Detailed, IncloudSphere has been responsible for virtual fusion, distribution according to need and the high-efficiency management of bottom physical resource, Ke Yixian
Write agility and the motility improving resource delivery, promote the service efficiency of resource, provide resource incessantly for upper-layer service
Ensure and telescopic resource provision.
For physical function PF, PF be one with the PCI-e equipment of SR_IOV function, in host, VF can be entered
Line pipe reason and configuration.
The PCI-e function of lightweight, the VF configuration by PF can be realized for virtual functions VF, VF, can directly divide
Dispensing virtual machine uses, and one or more VF can distribute to single virtual machine and use.
This method is by SR_IOV technology so that virtual machine can directly use physical network card, and multiple virtual
Machine shares physical resource by distribution VF, has carried out the realization of SR_IOV technology based on IncloudSphere system so that many
Individual virtual machine can share same physical network card resource, improves the network interface card serviceability of virtual machine.This method can be by list
Individual physical network card invents multiple VF, and VF is distributed to virtual machine so that virtual machine can directly use physical network card function,
In raising IncloudSphere, virtual machine is for the serviceability of I/O.
For IncloudSphere system, IncloudSphere virtualization system based on KVM, can by one or
Multiple VF distribute to a client computer, and client computer directly operates with VF without KVM's by the VF driver of self
Participate in, so make virtual machine can share physical equipment, and in the case of there is no the software overhead of CPU and Hypervisor
Perform I/O, improve the virtual machine serviceability to I/O, and also the port number of virtual switch can be reduced.
The present invention carries out the realization of SR_IOV technology based on IncloudSphere system, and detailed process is: open in Bios
Open VT-D/IOMMU and SR_IOV function；Amendment kernel startup item, opens iommu function at kernel；VF is distributed for physical network card；
VF is supplied to virtual machine use.SR_IOV technology is achieved so that multiple virtual machines are permissible in IncloudSphere system
Sharing the physical function of network interface card, the present invention also can support the function that is used in mixed way of physical network card: is distributed to by physical network card virtual
Switch and open SR_IOV function, the present invention is for using Intel processor and the AMD processor of SR_IOV function
Network interface card provide well support.
Based on this method, in specific implementation process, comprise the following steps:
The first step, opens IOMMU (AMD processor) or VT-D (Intel processor) at BIOS, with reference to Fig. 2, supports
The Intel processor of SR_IOV opens VT-D in BIOS, and enables SR_IOV function, with reference to Fig. 3, supports SR_IOV's
Intel processor opens SR_IOV in BIOS.
Second step, opens IOMMU in kernel, concrete operations be in/etc/default/grub file with GRUB_
CMDLINE_LINUX is the row started, for supporting the Intel processor write intel_iommu=on of SR_IOV, for propping up
Hold the AMD processor write iommu=1 of SR_IOV.
3rd step, the SR_IOV function of configuration physical network card ethi, the PF loading network interface card drives, configuration/sys/class/
Net/ethi/device/sriov_numfs file, the quantity of write VF, after write, unloading VF drives.For mac ground in VF
Location is all the situation of 0, it is possible to use mac address is manually specified in ip link set order, it is also possible to by upgrading kernel or VF
The method driven, solves this problem.
4th step, distributes to VF virtual machine and uses, as a example by Intel 82576 type network interface card, uses lspci | grep
7 VF just added are listed in 82576 orders, check that the instruction of the newly added VF of Intel 82576 type network interface card is as follows:
03:00.0 Ethernet controller:Intel Corporation 82576Gigabit Network
Connection(rev 01)
03:00.1 Ethernet controller:Intel Corporation 82576Gigabit Network
