Method determining whether to seek operator assistance for incompatible virtual environment migration
View Patent ↗An incompatibility problem during a virtual environment migration from a first host to a second host can be addressed by changing a configuration of the virtual environment and/or by migrating the virtual environment to a host other than the second host. A migration advisor module is configured to take such action automatically upon detection of the incompatibility problem. Alternatively, the migration advisor module may take such action with assistance and/or input from an operator. The migration advisor module can change the configuration of the virtual environment by removing unnecessary components of the virtual environment and causing the reconfigured virtual environment to be migrated to the second host. Alternatively, the migration advisor module can cause the virtual environment to be migrated to a third host with sufficient physical system resources to meet the requirements of the virtual environment.
1. A method for addressing migration incompatibility, comprising the steps of:
receiving information regarding a request to migrate a virtual environment (“VE”) from a first host to a second host;
determining that the VE is incompatible with the second host because available physical system resources of the second host do not meet at least one physical system requirement of the VE;
determining whether to seek operator assistance to address the incompatibility;
in response to determining not to seek operator assistance:
determining, based on at least one rule, whether to address the incompatibility by one of (a) migrating the VE to a host that is not the second host, and (b) reconfiguring the VE, and
automatically causing the VE to be migrated from the first host to a third host in response to determining, based on the at least one rule, to address the incompatibility by migrating the VE to a host that is not the second host, the third host having sufficient physical resources to meet the at least one physical system requirement of the VE,
in response to determining, based on the at least one rule, to address the incompatibility by reconfiguring the VE
automatically reconfiguring the VE by removing at least one unnecessary component from the VE, and
causing the reconfigured VE to be migrated from the first host to the second host; and
in response to determining to seek operator assistance:
outputting at least one request to an operator for an instruction on how to address the incompatibility,
reading at least one instruction provided by the operator in response to the at least one request, and
addressing the incompatibility, based on the at least one instruction, by one of (a) causing the VE to be migrated to a host that is not the second host, and (b) causing a reconfigured version of the VE to be migrated to the second host, a configuration of the reconfigured version of the VE being based on at least one input from the operator.
