Selective purging of entries of structures associated with address translation in a virtualized environment

A computer system for facilitating processing in a computing environment, said computer system comprising:

• a memory;
• and
• a processor in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
• obtaining a request to purge entries of a structure associated with address translation;
• determining, based on obtaining the request, whether selective purging of the structure associated with address translation is to be performed;
• and
• selectively purging one or more entries of the structure associated with address translation, based on determining that selective purging is to be performed, the selectively purging clearing the one or more entries of the structure associated with address translation for a host of the computing environment and leaving one or more entries of one or more guest operating systems in the structure associated with address translation, the one or more guest operating systems being managed by the host.

A computer-implemented method of facilitating processing in a computing environment, said computer-implemented method comprising:

• obtaining, by a processor, a request to purge entries of a structure associated with address translation;
• determining, based on obtaining the request, whether selective purging of the structure associated with address translation is to be performed;
• and
• selectively purging one or more entries of the structure associated with address translation, based on determining that selective purging is to be performed, the selectively purging clearing the one or more entries of the structure associated with address translation for a host of the computing environment and leaving one or more entries of one or more guest operating systems in the structure associated with address translation, the one or more guest operating systems being managed by the host.
