[libvirt-users] Question about setns recognising in libvirt autoconf
Hi experts, When I test lxc container with lxc-enter-namespace command, It reported an error as following: root@debian:~/github/libvirt# vir lxc-enter-namespace lxc --noseclabel /bin/df -hl error: Cannot get namespaces for 3145: Function not implemented It seems that setns is not supported by my kernel. But from the following info, It seemed the reason is just libvirt/autoconf doesn't recgonise setns. root@debian:~/github/libvirt# grep setns /proc/kallsyms ffffffff8105b78b T SyS_setns ffffffff8105b78b T sys_setns root@debian:~/github/libvirt# ./configure | grep setns checking for setns... no What the problem really is ? How can I fix this problem? Thanks~ ------------------ Best regards! GuanQiang 2013-12-09

How can I fix this problem?What's the result of grep -R "setns" /usr/include/*

How can I fix this problem?What's the result of grep -R "setns" /usr/include/* Hi Gaofeng, The result you want is as following: root@debian:~/github/libvirt# grep -R "setns" /usr/include/* /usr/include/asm-generic/unistd.h:#define __NR_setns 268 /usr/include/asm-generic/unistd.h:__SYSCALL(__NR_setns, sys_setns) /usr/include/x86_64-linux-gnu/bits/syscall.h:#define SYS_setns __NR_setns /usr/include/x86_64-linux-gnu/asm/unistd_64.h:#define __NR_setns 308 /usr/include/x86_64-linux-gnu/asm/unistd_64.h:__SYSCALL(__NR_setns, sys_setns) /usr/include/x86_64-linux-gnu/asm/unistd_32.h:#define __NR_setns 346 ------------------ Best regards!
