[Lxc-users] Error starting a container - could not unmount old rootfs

[Nirmal Guhan]

Hi,

When starting a container, am getting an error as :

lxc-start: Device or resource busy - could not unmount old rootfs
lxc-start: failed to pivot_root to '/lxc/f12'
lxc-start: failed to set rootfs for 'f12connew'
lxc-start: failed to setup the container

My config is very simple :
lxc.utsname = f12connew
lxc.rootfs = /lxc/f12
lxc.mount = /lxc/f12.fstab
lxc.tty = 3

Am running 2.6.32.16 kernel. Am able to start the same container while
running the same kernel with only one difference - the one that does
NOT work has CONFIG_MACVLAN=y but I doubt if that is the issue.

Please help.

Thanx, Nirmal
