Dear sir:
I want to hook mmap system call in qemu, and I use libvirt to passthrough the environment argument like this:But it failed. I can hardly find out what is the matter! The log in libvirt like this:<qemu:commandline> <qemu:env name='LD_PRELOAD' value='/glibcHookMMAP.so'/> </qemu:commandline>
Firstly, I think it's the problem of authority. But the file glibcHookMMAP.so has been done with command `ERROR: ld.so: object '/glibcHookMMAP.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
chmod 777`
. My environment is as follows: Ubuntu 18.04.2 Linux 5.4.0-92 libvirt 4.0.0 qemu 2.11.1
Look forward to your feedbacks.
Sincerely yours
