Pass "noexec=off" to the kernel, and it won't set the NX bit in it's page-table entries, and I presume Xen will just use the same bits as the guest asks for... One would think, at least.. [I haven't tried this, I just scanned the kernel source code for the boot-line argument, as I knew there is some way to enable/disable it...] Care to divulge what the app is so I can add it to the list of apps that I'm not going to use? ;-) -- Mats > -----Original Message----- > From: xen-devel-bounces@xxxxxxxxxxxxxxxxxxx > [mailto:xen-devel-bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of > Hans-Christian Armingeon > Sent: 28 June 2006 10:16 > To: xen-devel@xxxxxxxxxxxxxxxxxxx > Subject: [Xen-devel] how to disable the NX flag in a domU? > > Hi, > > I am having problems with an unclean written closed source > application, which segfaults by time, because it has > executable code on the stack. > > Is it possible, to disable the NX bit on modern processors > for a domU?
