According to one embodiment, a semi-transparent panel is displayed superimposed on a graphical user interface (GUI) page in response to a first user interaction with the GUI page. The GUI page provides a user interface for managing a virtualization system. A dialog box is then displayed on top of the semi-transparent panel, where the dialog box is to receive an input from the user. An alert is generated in response to a second user interaction with an area of the semi-transparent panel other than the dialog box, where the alert indicates that the second user interaction is invalid. ## Claims ### Claim 1 A method comprising: displaying, by a processing device, a panel superimposed on a graphical user interface (GUI) virtualization system management page; displaying on top of the panel a dialog box comprising an input user interface element; receiving, by an event handler of the panel, an event associated with a user interaction with the panel outside of the dialog box; generating, by the processing device, an alert in response to the user interaction indicating that the user interaction is invalid, wherein the alert is in a visual form; and preventing an event handler of the GUI virtualization system management page from receiving the event. ### Claim 2 (depends on 1) The method of claim 1, wherein the panel indicates that at least one control of the GUI virtualization system management page is inaccessible. ### Claim 3 (depends on 2) The method of claim 2, wherein a semi-transparent panel reduces an overall display resolution of the GUI virtualization system management page. ### Claim 4 (depends on 1) The method of claim 1, wherein the alert is also generated in an audible form. ### Claim 5 (depends on 1) The method of claim 1, wherein a user interacts with a semi-transparent panel outside of the dialog box, an event associated with the user interaction is received by an event handler of the semi-transparent panel without providing the event to an event handler of the GUI virtualization system management page underneath. ### Claim 6 (depends on 1) The method of claim 1, wherein the GUI virtualization system management page is presented as part of a Web portal of a virtualization management system and a Windows presentation foundation (WPF) application, wherein the virtualization management system is to manage a virtual machine for a client. ### Claim 7 (depends on 6) The method of claim 6, further comprising receiving a user interaction activating a control of the GUI virtualization system management page for creating a host which requires a certain parameter to proceed for hosting a virtual machine. ### Claim 8 A non-transitory computer readable storage medium including instructions that, when executed by a processing device, cause the processing device to execute operations comprising: displaying, by the processing device, a panel superimposed on a graphical user interface (GUI) virtualization system management page; displaying on top of the panel a dialog box comprising an input user interface element; receiving, by an event handler of the panel, an event associated with a user interaction with the panel outside of the dialog box; generating, by the processing device, an alert in response to the user interaction indicating that the user interaction is invalid, wherein the alert is in a visual form; and preventing an event handler of the GUI virtualization system management page from receiving the event. ### Claim 9 (depends on 8) The non-transitory computer readable storage medium of claim 8, wherein the panel indicates that at least one control of the GUI virtualization system management page is inaccessible. ### Claim 10 (depends on 9) The non-transitory computer readable storage medium of claim 9, wherein a semi-transparent panel reduces an overall display resolution of the GUI virtualization system management page. ### Claim 11 (depends on 8) The non-transitory computer readable storage medium of claim 8, wherein the alert is also generated in an audible form. ### Claim 12 (depends on 8) The non-transitory computer readable storage medium of claim 8, wherein a the user interacts with a semi-transparent panel outside of the dialog box, an event associated with the user interaction is received by an event handler of the semi-transparent panel without providing the event to an event handler of the GUI virtualization system management page underneath. ### Claim 13 (depends on 8) The non-transitory computer readable storage medium of claim 8, wherein the GUI virtualization system management page is presented as part of a Web portal of a virtualization management system and a Windows presentation foundation (WPF) application, wherein the virtualization management system is to manage a virtual machine for a client. ### Claim 14 (depends on 13) The non-transitory computer readable storage medium of claim 13, further comprising receiving a user interaction activating a control of the GUI virtualization system management page for creating a host which requires a certain parameter to proceed for hosting a virtual machine. ### Claim 15 A system, comprising: a display device; a processing device coupled to the display device; and a memory coupled to the processing device to store computer instructions, which when executed from the memory, cause the processing device to: display a panel superimposed on a graphical user interface (GUI) virtualization system management page, display on top of the panel a dialog box comprising an input user interface element, receive, by an event handler of the panel, an event associated with a user interaction with the panel outside of the dialog box; generate an alert in response to the user interaction indicating that the user interaction is invalid, wherein the alert is in a visual form; and prevent an event handler of the GUI virtualization system management page from receiving the event. ### Claim 16 (depends on 15) The system of claim 15, wherein the panel indicates that at least one control of the GUI virtualization system management page is inaccessible. ### Claim 17 (depends on 16) The system of claim 16, wherein a semi-transparent panel reduces an overall display resolution of the GUI virtualization system management page. ### Claim 18 (depends on 15) The system of claim 15, wherein the alert is also generated in an audible form. ### Claim 19 (depends on 15) The system of claim 15, wherein a the user interacts with a semi-transparent panel outside of the dialog box, an event associated with the user interaction is received by an event handler of the semi-transparent panel without providing the event to an event handler of the GUI virtualization system management page underneath. ### Claim 20 (depends on 15) The system of claim 15, wherein the GUI virtualization system management page is presented as part of a Web portal of a virtualization management system and a Windows presentation foundation (WPF) application, wherein the virtualization management system is to manage a virtual machine for a client.
