host: centos-6.5
kernel: 3.13.2-4.el6.x86_64
guest: fedora20
since libvirt-1.2.2 i can not shutdown this domain. works fine with
libvirt-1.2.1
# virsh shutdown fedora2
error: Failed to shutdown domain fedora2
error: Mount namespaces are not available on this platform: Function
not implemented
from the logfile: 14478: error : virProcessRunInMountNamespace:982 :
Mount namespaces are not available on this platform: Function not
implemented
the buildhost for the rpm is a centos-6.5 system with kernel 3.1.8
(dont ask! its a vserver system) and the test for "setns" failed
configure:9592: checking for setns
configure:9592: gcc -std=gnu99 -o conftest -g -O2 conftest.c >&5
/tmp/cchlir6v.o: In function `main':
/builddir/build/BUILD/libvirt-1.2.2/conftest.c:184: undefined
reference to `setns'
collect2: ld returned 1 exit status
setns() was added in glibc-2.14 centos6 has glibc-2.12
attached is a fix for this problem.
