From: Michal Privoznik <mpriv...@redhat.com> Currently, when the preallocating guest memory process fails, a not so helpful error message is printed out:
# virsh start migt10 error: Failed to start domain migt10 error: internal error: process exited while connecting to monitor: os_mem_prealloc: failed to preallocate pages >From the error message it's not clear at the first glance where the problem lies. However, changing the error message might give users a clue.
