Description of problem:

Not sure if qemu or libvirt bug.

Trying to start an ubuntu trusty guest gives me this:

$ virsh start trusty
error: Failed to start domain trusty
error: internal error: process exited while connecting to monitor: /usr/bin/qemu-system-x86_64: error while loading shared libraries: librados.so.2: cannot enable executable stack as shared object requires: Permission denied


NVR: qemu-system-x86-2.1.0-0.3.rc1.fc22.x86_64

While that would indicate that librados.so.2 needs an executable
stack, I have just checked the latest Rawhide library and it's OK:

$ rpm2cpio ceph-libs-0.81.0-5.fc22.x86_64.rpm | cpio -id
$ readelf -l ./usr/lib64/librados.so.2.0.0 

...
  GNU_STACK      0x0000000000000000 0x0000000000000000 0x0000000000000000
                 0x0000000000000000 0x0000000000000000  RW     10
...

Which version of ceph-libs is installed?
Comment 2 Lokesh Mandvekar 2014-07-16 19:16:11 UTC 
So looks like I had libcephfs1 and librados2 installed and not ceph-libs (probably something went wrong during my system upgrade(?)) ... I removed the former 2 and installed the latter, and everything seems to work now.

Thanks!
