The **qrexec** framework is used by core Qubes components to implement communication between domains. The **qrexec framework** is used by core Qubes components to implement communication between domains.
Qubes domains are strictly isolated by design. Qubes domains are strictly isolated by design.
However, the OS needs a mechanism to allow the administrative domain (dom0) to force command execution in another domain (VM). However, the OS needs a mechanism to allow the administrative domain (dom0) to force command execution in another domain (VM).
For instance, when a user selects an application from the KDE menu, it should start in the selected VM. For instance, when a user selects an application from the KDE menu, it should start in the selected VM.
