Hi Suyi,
qemu-trivial is a mailing list for QEMU patches, questions should be
directed at the regular QEMU mailing list. I have CCed qemu-devel and
libvirt-list so your question will go to the QEMU and libvirt
communities.
Are you sure your libvirt configuration allows the QEMU process to
access /dev/shm? You may have SELinux enabled.
