Interesting. The pid 114979 you are attaching to - are you sure it's the
pid of libvirtd? I tend to use: "gdb -p $(pgrep libvirtd)" and I don't
have to bother with obtaining the daemon's pid.
Also, ptrace seems to have failed. Reading its manpage:
EPERM The specified process cannot be traced. This could be because
the tracer has insufficient privileges (the required capability is
CAP_SYS_PTRACE); unprivileged processes cannot trace processes that they
cannot send signals to or those running set-user-ID/set-group-ID
programs, for obvious reasons. Alternatively, the process may already
be being traced, or (on kernels before 2.6.26) be init(1) (PID 1).
Are you sure you don't lack CAP_SYS_PTRACE?
