Specific embodiment
For problems of the prior art, the embodiment of the present invention provides a kind of method of vm migration, and the method is applied
In inclusion vm administrative center, the data center network of evb edge switch, vm and user network.Wherein, vm and evb edge
Switch connects, and vm is connected with vm administrative center, and passes through big double layer network between evb edge switch and user network even
Connect.Further, user network refers to that renting vm provides user or the company of service, and this user network can be an equipment
The network of (as pc) or multiple equipment composition；Additionally, big double layer network refers to adopt big two layers of technology in data center
Network, this big two layers of technology can be trill(transparent interconnection of lots of links, many
Link transparency interconnect), spb(shortest path bridging, shortest path bridge), vxlan(virtual extended
Vlan, virtual extended vlan) etc..
Application scenarios schematic diagram with Fig. 2 as the embodiment of the present invention, data center network is included in data center's a data
, all there are multiple vm in data center's a data center b in heart b, and data center's a data center b backups each other.This data
Central site network also includes vm administrative center, and this vm administrative center is used for managing all vm in data center's a data center b.
This data center network also includes the evb edge switch a being connected with data center a and the evb side being connected with data center b
Edge switch b, and evb edge switch a and evb edge switch b is all connected to big double layer network.This data center network is also
Including user network, and this user network is connected to big double layer network.
In the data, services that user network uses the vm in data center to provide, user does not perceive this vm and is located at data
Also it is in data center b in a of center, but user network needs the continual data access service providing using vm.
, then under above-mentioned application scenarios taking the vm a in subscriber network access data center a as a example, as shown in figure 3, the side of this vm migration
Method comprises the following steps:
Step 301, evb edge switch (if evb edge switch a) is in vm(such as vm a) corresponding vsi configures
cfm.Wherein, the vlan of this cfm is the corresponding specified vlan of flow of this vm, and this cfm is used for evb edge switch and use
Link between the network of family carries out fault detect.
Cfm is the end-to-end oam(operations on two layers of link based on vlan, administration and
Maintenance, Operations, Administration and Maintenance) mechanism, for detecting connectivity of link in double layer network, confirm fault simultaneously really
Determine fault and position occurs.Based on this, due to an interface (i.e. vsi) can be corresponded to for each vm on evb edge switch,
And the flow of each vm has specified vlan.Therefore, in the embodiment of the present invention, evb edge switch a can be corresponding in vm a
Apply cfm technology on vsi, and configure the corresponding specified vlan of the flow of vm a for interior to mep(maintenance
Association end point, safeguards end points).In addition it is also necessary to the mep node of cfm is configured on heterogeneous networks segmentation,
And the vlan of mep node is to specify vlan, for example, the equipment that path is passed through between evb edge switch a and user network
(equipment as in big double layer network) upper mep node configuring cfm.Based on this, between evb edge switch a and user network
Equipment pass through to send ccm message to the corresponding vsi of vma, and carry specified vlan in this ccm message, so that evb edge is handed over
The a that changes planes can determine link between evb edge switch a and user network whether fault according to the reception condition of ccm message.
In the embodiment of the present invention, according to the actual requirements, by different setting between evb edge switch and user network
The mep node of standby upper configuration cfm, can detect the chain of the various network segments between evb edge switch and user network then
Road whether fault, determines link between evb edge switch and user network whether fault then.
Step 302, evb edge switch judges whether to receive the equipment between this evb edge switch and user network
The ccm message sending to vsi；If it is, execution step 303；If not, execution step 304.
Under application scenarios shown in Fig. 2, evb edge switch a judges (to be entered according to practical experience in Preset Time
Row setting) in whether receive the ccm that the equipment between this evb edge switch a and user network sends to the corresponding vsi of vm a
Message；If it is, execution step 303；If not, execution step 304.
Step 303, evb edge switch is sent out to vsi receiving the equipment between this evb edge switch and user network
When carrying specified vlan in the ccm message sending, and this ccm message, evb edge switch determines this evb edge switch and use
Link between the network of family is normal, does not now need to carry out virtual machine (vm) migration.
Step 304, evb edge switch does not receive between this evb edge switch and user network in Preset Time
Equipment send to vsi ccm message when, evb edge switch determines the chain between this evb edge switch and user network
Breaking down in road, now needs to carry out virtual machine (vm) migration, and execute subsequent step 305.
Step 305, evb edge switch is by the information of the link failure between this evb edge switch and user network
Notify to vm, by link failure between receiving from the evb edge switch and user network of evb edge switch for the vm
After information, notify vm administrative center to trigger this vm and carry out virtual machine (vm) migration.
As shown in figure 4, associate the tlv(type length value of message, type lengths values for vdp) form schematic diagram,
On this basis, in the embodiment of the present invention, the status(identity in message can be associated by changing vdp) state, to show
Link between evb edge switch and user network breaks down, and reminds vm to be currently down state, and triggers vm and enter
Row virtual machine (vm) migration.
Based on this, the information of the link failure between this evb edge switch and user network is led to by evb edge switch
Know to vm, specifically include: evb edge switch sends vdp association message to vm；Wherein, this vdp associates the status in message
State is designated identification (0x6 or 0x7,0xf as status state reservation etc.), and when vdp associates the status shape in message
When state is designated identification, show that the link between this evb edge switch and user network breaks down, and vm is currently can not
Use state.
Further, vm is receiving after the vdp association message of evb edge switch, if it find that this vdp association is reported
Status state in literary composition is designated identification, then vm notifies vm administrative center to trigger this vm and carry out virtual machine (vm) migration, is managed by vm
Center by this vm from current data Center shift to another data center mutually redundant with current data center.For example, vm pipe
Vm a is moved to another data center b mutually redundant with current data center a from current data center a by reason center.
In vm administrative center, vm a is moved to mutually redundant another with current data center a from current data center a
During data center b, vm administrative center determines the vm a being migrated first, according to vsi type numbering and the vsi of vm a
Type version, using the vm a after vm b(moves to data center b with vm a identical vsi id, it is new vm) upper wound
Build vsi example, and bind vsi and filter information, then start the vdp of vm b side in data center b.
Further, vm b sends vdp association message to evb edge switch b, carries vsi in this vdp association message
Type numbering, vsi type version, vsi id, vsi id format and vsi filter information.Evb edge switch b verifies vdp
After association message is legal, vdp association message is sent to network management server.Network management server notifies evb edge to hand over
The b that changes planes creates vsi, and binds characteristic information (vsi filters information) for this vsi, and network management server notifies evb edge to hand over
This vsi of b that changes planes is pre-association state.After creating vsi, network management server associates, according to vdp, the vsi carrying in message
Type numbering and vsi type version querying vtdb, will create to evb edge switch b to the policy distribution of vsi type in vtdb
On the vsi building, but strategy wouldn't come into force.Network management server notifies evb edge switch b, and this time vsi reaches the standard grade successfully in advance.
Evb edge switch is replied vm b pre-association and is processed successfully.
Afterwards, vm administrative center notifies former vm a to prepare to stop.Vm a sends vdp to evb edge switch a and goes association to ask
Ask.Evb edge switch a is receiving after vdp goes association request, deletes vsi associated ports, removes the strategy configuration of interface, to
Network management server sends the offline notice of vm a.Network management server notifies evb edge switch a to go at association request
Manage successfully, so far vm a is successfully offline.
Afterwards, vm administrative center notifies new vm b to prepare to reach the standard grade work.Vm b sends vdp association to evb edge switch b
Request.Evb edge switch b, after receiving vdp association request, vsi associated interface is switched to association status, and related strategy is opened
Beginning comes into force.Meanwhile, evb edge switch b notifies vm b, and association request is processed successfully.Follow-up vm b timing sends vdp association report
