[Users] unable to migrate / checkpoint

[Samuel Tremblay-Cossette]

Hi,

I'm unable to checkpoint and migrate my VEs. I'm using
2.6.24-19-openvz that come with Ubuntu 8.04.

Here is the error message:

root at frontend:~# vzctl chkpnt 2
Setting up checkpoint...
	suspend...
	dump...
Can not dump VE: Invalid argument
Error: d_path is invisible /dev
Checkpointing failed

kernel: CPT ERR: f6d61000,2 :d_path is invisible /dev

And some info about my setup:

root at frontend:~# sysctl fs.vsyscall vm.vdso_enabled
fs.vsyscall = 0
vm.vdso_enabled = 0

root at frontend:~# vzctl enter 2
entered into VE 2

All the best,
