receiving, at the hypervisor, the identifier from the host OS upon a selection by a user of the alert on the notification bar controlled by the host OS;

transmitting, by the hypervisor, the identifier to the hypervisor-aware service; and

requesting, by the hypervisor-aware service, the guest OS to launch the application by providing the identifier to the guest OS.

5. The method of claim 1 , wherein the notification bar controlled by the host OS displays a guest environment icon when the UI of the host environment is displayed on the mobile device, wherein a selection of the guest environment icon causes the mobile device to display the UI of the guest environment.

6. The method of claim 1 , wherein the notification bar controlled by the host OS displays additional UI elements to differentiate icons displayed in the notification bar relating to applications of the guest OS from icons displayed in the notification bar relating to applications of the host OS.

7. A non-transitory computer-readable storage medium including instructions that, when executed on a processor in a mobile device, causes the processor to display alerts provided by applications of a guest environment in a notification bar controlled by a host operating system (OS) in a host environment of the mobile device, wherein the guest environment is running in a virtual machine supported by a hypervisor running within the host environment, by performing the steps of:

registering, by a hypervisor-aware service running on a guest OS of the virtual machine, with the guest OS to be notified by the guest OS when applications of the guest environment request the guest OS to present alerts in a notification bar controlled by the guest OS, wherein the hypervisor-aware service is aware that it is running in the virtual machine on top of the hypervisor and can request or provide data and services to and from the hypervisor;

upon receipt by the hypervisor-aware service of a notification by the guest OS of an application requesting presentation of an alert in the notification bar controlled by the guest OS, forwarding the notification to the hypervisor, wherein the alert is one of an e-mail alert, a calendar alert, and a telephone call alert; and

transmitting, by the hypervisor, a corresponding request to a notification management component of the host OS to present the alert on the notification bar controlled by the host, the notification management component configured to present the alert on the notification bar controlled by the host OS concurrently with a notification from an application of the host OS and system information generated by the host OS;

wherein display of the notification bar controlled by the host OS persists when a user interface (UI) of the guest environment is displayed in place of a UI of the host environment and when the UI of the host environment is displayed in place of the UI of the guest environment, and

wherein, upon a swipe motion by a user on the notification bar controlled by the host OS, the host OS displays an expanded notification bar that comprises additional detailed information that differentiates alerts of applications of the guest OS from alerts of applications of the host OS.

8. The non-transitory computer-readable storage medium of claim 7 , wherein, when displaying the UI of the guest environment on the mobile device, the notification bar controlled by the host OS is displayed rather than displaying the notification bar controlled by the guest OS.

9. The non-transitory computer-readable storage medium of claim 7 , wherein the corresponding request transmitted by the hypervisor to the host OS includes an identifier associating the alert with the application.

10. The non-transitory computer-readable storage medium of claim 9 , wherein the instructions further cause the processor to perform the steps of:

receiving, at the hypervisor, the identifier from the host OS upon a selection by a user of the alert on the notification bar controlled by the host OS;

transmitting, by the hypervisor, the identifier to the hypervisor-aware service; and

requesting, by the hypervisor-aware service, the guest OS to launch the application by providing the identifier to the guest OS.

11. The non-transitory computer-readable storage medium of claim 7 , wherein the notification bar controlled by the host OS displays a guest environment icon when the UI of the host environment is displayed on the mobile device, wherein a selection of the guest environment icon causes the mobile device to display the UI of the guest environment.

12. The non-transitory computer-readable storage medium of claim 7 , wherein the notification bar controlled by the host OS displays additional UI elements to differentiate icons displayed in the notification bar relating to applications of the guest OS from icons displayed in the notification bar relating to applications of the host OS.

13. A mobile device, comprising:

a host operating system (OS) providing a host environment;

a hypervisor running within the host environment supporting a virtual machine, the

virtual machine having a guest OS providing a guest environment; and

a processor configured to execute the host OS and the hypervisor and configured to:

register a hypervisor-aware service running on the guest OS of the virtual machine with the guest OS to be notified by the guest OS when applications of the guest environment request the guest OS to present alerts in a notification bar controlled by the guest OS, wherein the hypervisor-aware service is aware that it is running in the virtual machine on top of the hypervisor and can request or provide data and services to and from the hypervisor;

forward the notification to the hypervisor upon receipt by the hypervisor-aware service of a notification by the guest OS of an application requesting presentation of an alert in the notification bar controlled by the guest OS, wherein the alert is one of an email alert, a calendar alert, and a telephone call alert; and

transmit, through the hypervisor, a corresponding request to a notification management component of the host OS to present the alert on a notification bar controlled by the host OS, the notification management component configured to present the alert on the notification bar controlled by the host OS concurrently with a notification from an application of the host OS and system information generated by the host OS;

wherein display of the notification bar controlled by the host OS persists when a user interface (UI) of the guest environment is displayed in place of a UI of the host environment and when the UI of the host environment is displayed in place of the UI of the guest environment, and

wherein, upon a swipe motion by a user on the notification bar controlled by the host OS, the host OS displays an expanded notification bar that comprises additional detailed information that differentiates alerts of applications of the guest OS from alerts of applications of the host OS.
