[Lxc-users] lxc-start fails when / is a shared mount
Hi list, I just ran into this problem: If you do # mount --make-shared / to mark / as a shared mount then lxc-start fails when you have specified a lxc.rootfs in the configuration file. The error that lxc-start gives is the following: Invalid argument - pivot_root syscall failed Is this the normal behavior or is this a kernel bug? -- BlackBerryreg; DevCon Americas, Oct. 18-20, San Francisco, CA Learn about the latest advances in developing for the BlackBerryreg; mobile platform with sessions, labs more.

Perhaps lxc should fall back to chroot when pivot_root fails. -serge -- BlackBerryreg; DevCon Americas, Oct. 18-20, San Francisco, CA Learn about the latest advances in developing for the BlackBerryreg; mobile platform with sessions, labs more.

Re: [Lxc-users] Help regarding lxc
hello all Thnks 4 comments. I hv resolved that issue, when we comment lxc.rootfs the lxc-execute works. My question is why for lxc-execute the rootfs is not needed ? Regards, Nishant.
