Hello List, this is my first post to the list and I hope my English is good enough.

I want to use Borland Delphi 7 in a HVM WinXP, but when I run my program with the debugger from Delphi the following error occurred: Translated: "The Program can't be initialized (0xC0000005). Click OK to quit the Program" Original German: "Die Anwendung konnte nicht richtig initialisiert werden (0xC0000005). Klicken Sie auf OK, um die Anwendung zu beenden".

After the click on OK the following messages are shown: "Internal Error PRO-1826" and "Internal Error PRO-1840". After this messages the following message occurs: "An error occurs with the following message: access violation at 0x00000000: read from 0x00000000. Process halted."

When I start the program without the debugger then it runs without errors, but I need the debugger!

I don't know how the debugger from Delphi interact with the program but it seems that the debugger gets the wrong address from Windows or, perhaps, it has a hard-coded address that doesn't work with Xen.

I've tried Xen 3.0.2 and 3.0.4 with Win2k and XP. I also tried a newer Borland Delphi Version (Delphi PE 2005) but the same error occurred.

My Dom0 is OpenSuSE 10.1 on an AMD Athlon64 3200+

Is this a failure in Xen? In VMWare it works without problems!
Has anyone a suggestion how to bypass this problem?
