Hello,

This trick doesn't work anymore for hathor on Linux 2.6.40.6-0 (fedora 15).

Still mmap: permission denied

Has somebody resolved this ?

Note: Ubuntu Karmic uses kernel 2.6.31. Setting mmap_min_addr to 4096 doesn't help.

In fact, it becomes the cause of failure with newer qemu, which internally sets GUEST_BASE based on mmap_min_addr.

One should not use mmap_min_addr with qemu 0.10.0.

Thank you for this information. It worked fine for me.

However, it seems that this solution doesn't work on Linux kernel 2.6.31 (from rc7 on).

Thanks for blogging. I was about to undo everything before I came across your blog.

The solution proposed above seems to solve the problem partially. But now I get other errors related to gcc compilation

------
:1: sorry, unimplemented: had to relocate PCH
:1: confused by earlier errors, bailing out
------

Did some googling about this and found http://gcc.gnu.org/ml/gcc-bugs/2004-05/msg00559.html, which basically says that the gcc compiler's PreCompiled Headers optimization fails because of wrong mmap address. Any clues on how to overcome this?

This was the issue my blog post was about -- only the comments are about the vdso issue.

solved :

echo 4096 | sudo tee /proc/sys/vm/mmap_min_addr
