grep setns /proc/kallsyms
and
grep setns the config.log of libvirt.
Hi, Gaofeng, thanks for your help. The info you want are:
hzguanqiang at debian:~/github/libvirt$ sudo grep setns /var/log/libvirt/libvirtd.log
hzguanqiang at debian:~/github/libvirt$ grep setns /proc/kallsyms
ffffffff8105b993 T sys_setns
What I found really strange is that the error info returned by the command.
hzguanqiang at debian:~$ vir lxc-enter-namespace 1544 --noseclabel /bin/df -hl
error: Cannot get namespaces for 1545: Function not implemented
The instance id is 1544, but the error info hint cannot get ns for 1545.
The libvirt code of mine is of version 1.1.4 from github (git checkout v1.1.4 -b stable1.1.4 )
------------------
Best regards!
