A method for intercepting an application prompt before it reaches the user interface, wherein the application prompt has been transmitted from the computer application and intended to reach the user interface. The method also includes translating the intercepted application prompt from a source language to a target user language, and in response to translating the intercepted application prompt, transmitting the translated application prompt to the user interface. The method also includes intercepting, in response to the application prompt, user input from the user interface, wherein the user input is intended to reach the computer application. The method also includes translating the user input from the target language to the source language, and in response to translating the intercepted application prompt, transmitting the translated user input to the computer application.

Translating prompt and user input

A method for mirroring virtual machines from a primary host to a secondary host. The method includes tracking changes for each of a plurality of memory pages and processor states for one or more primary host virtual machines. Responsive to an occurrence of a checkpoint, the primary host virtual machines are stopped. A determination is made if each of the memory pages is frequently changed. In response to the memory page being frequently changed, the frequently changed memory page is marked as being writeable and copied to a buffer. In response to the memory page being infrequently changed, the infrequently changed memory page is marked as being read only. The one or more primary host virtual machines are resumed. A copy of the memory pages, the buffer and changes to the processor states are transmitted to the secondary host.
