It states.
Below with reference to specific embodiment, the method for Autonomic Migration Framework virtual machine provided in an embodiment of the present invention is made to carry out one
Step is described in detail, as shown in figure 5, this method may comprise steps of:
Step 501: obtaining each monitored corresponding mobility threshold of host, and the mobility threshold storage that will acquire is arrived
In migration strategy allocation list.
In an embodiment of the invention, it is directed to each monitored host, obtaining this, monitored host is corresponding moves
Threshold value is moved, mobility threshold is to need to carry out the critical CPU occupation value and EMS memory occupation value of virtual machine (vm) migration；Getting migration threshold
After value, the corresponding relationship between each monitored host and mobility threshold is being recorded in preset migration strategy allocation list.
For example, a virtual machine system includes 3 monitored hosts altogether, the mobility threshold of monitored host 1 accounts for for CPU
With value 80%, EMS memory occupation value 70%；The mobility threshold of monitored host 2 is CPU occupation value 80%；Monitored host 3 moves
Shifting threshold value is EMS memory occupation value 80%；By the corresponding mobility threshold storage of three monitored hosts to preset migration strategy
In allocation list.
Step 502: obtaining each monitored corresponding target virtual machine of host and destination host, and the mesh that will acquire
Virtual machine and destination host storage are marked into migration information detailed configuration table.
In an embodiment of the invention, it is directed to each monitored host, obtains the monitored corresponding mesh of host
Virtual machine and destination host are marked, wherein target virtual machine is the void being migrated away when the host hardware resource occupation that is monitored is excessively high
Quasi- machine, destination host are the move target of target virtual machine；After getting target virtual machine and destination host, presetting
Migration information detailed configuration table in record the corresponding relationship of each monitored host and target virtual machine and destination host.Its
In, it can be other monitored hosts in addition to this is monitored host corresponding to the destination host of monitored host, it can also be with
For other hosts except the host that is monitored unless each.
For example, the monitored corresponding target virtual machine of host 1 is virtual machine 1, corresponding destination host is destination host 1；
The monitored corresponding target virtual machine of host 2 is virtual machine 2, and corresponding destination host is destination host 2；Monitored host 3 is right
The target virtual machine answered is virtual machine 3, and corresponding destination host is destination host 3；Wherein destination host 3 and monitored host 1
For the same host.Above 3 monitored hosts and the corresponding relationship of target virtual machine and destination host are stored to setting in advance
In fixed migration information detailed configuration table.
Step 503: each monitored host recorded in migration strategy allocation list being monitored in real time, is obtained corresponding
First hardware resource occupation value.
In an embodiment of the invention, the monitored host of each recorded in migration strategy allocation list, root are directed to
According to the monitoring period of default settings, the CPU occupation value of the monitored host of real-time monitoring and memory are accounted within the same monitoring period
With value, after a monitoring end cycle, being averaged for the average value of CPU occupation value and EMS memory occupation value in the monitoring period is calculated
Value, using the average value of calculated CPU occupation value and the average value of EMS memory occupation value as the first hardware of the host that is monitored
Resource occupation value.
For example, the default monitoring period is 30s, monitored host 1, monitored host after a 30s, are being calculated separately
2 and CPU occupation value of the monitored host 3 within this 30s time average value and EMS memory occupation value average value, will be calculated
Average value is respectively as the corresponding first hardware resource occupation value of 3 monitored hosts.Wherein, be monitored host 1 corresponding the
One hardware resource occupation value is CPU occupation value 50%, EMS memory occupation value 40%；Monitored corresponding first hardware resource of host 2
Occupation value is CPU occupation value 90%, EMS memory occupation value 30%；The monitored corresponding first hardware resource occupation value of host 3 is CPU
Occupation value 80%, EMS memory occupation value 80%.
Step 504: being directed to each monitored host, judge that corresponding first hardware resource of host that is monitored occupies
Whether value is greater than corresponding mobility threshold, if so, step 505 is executed, it is no to then follow the steps 503.
In an embodiment of the invention, it is directed to each monitored host, this detected in step 503 is supervised
The corresponding migration of the host that is monitored recorded in the corresponding first hardware resource occupation value of control host and migration strategy allocation list
Threshold value is compared, if the first hardware resource occupation value is greater than mobility threshold, it is virtual to illustrate that the monitored host needs to carry out
Machine migration, correspondingly executes step 505；If the first hardware resource occupation value is less than or equal to mobility threshold, illustrate that this is supervised
Control host correspondingly executes step 503 without carrying out virtual machine (vm) migration.
For example, since the CPU occupation value in the corresponding first hardware resource occupation value of host 1 included that is monitored is 50%,
EMS memory occupation value is 40%, and CPU occupation value is 80% in the monitored corresponding mobility threshold of host 1, is by EMS memory occupation value
70%, since two parameters that the first hardware resource occupation value includes are respectively less than corresponding parameter in mobility threshold, so judgement
