Dear Developers,
I appreciate if you could help me with the following question; How we can send initialization parameters from xen to the Linux kernel in boot time, for example this parameter noexec=off.
Thanks in advance,

Configuration questions such as this are best addressed to the xen-users
mailing list.
If I've misunderstood and you are actually proposing a some development
related change then please take a look at
http://wiki.xen.org/wiki/AskingXenDevelQuestions to help you frame your
suggestion.
Thanks,
Ian.

My question was not about configuration, its main propose is how I can embed some initialization parameters in the Xen source code - for example in domain_build.c- that would pass as the boot time parameters to Linux kernel which is lunching in dom0.
Thanks in advance,

Why do you not do this via your bootloader configuration?
Ian.

But a user who can modify the command line can just as easily modify
which hypervisor binary they launch, at which point you need to start
thinking about trusted boot etc and if you are doing that you would
naturally measure the bootloader configuration too.
Anyway, you can do whatever checking or modifications you like to the
cmdline in construct_dom0().
Ian.

is there any solution for it? Thanks
I want to do this in the hypervisor level, because I'm going to prevent illegal modifications in the bootloader. as an instance, I want to prevent users from passing parameters such as noexec=off in boot time to the kernel.
