I don't know, I just rebooted and started the vm and it is mounted twice again. I lloked at /proc/mounts on the host and here is the diff between before-chkpnt and after-restore: < proc /proc proc rw 0 0 < sysfs /sys sysfs rw 0 0 < tmpfs /var/run tmpfs rw,mode=755 0 0 < tmpfs /var/lock tmpfs rw 0 0 < devpts /dev/pts devpts rw,gid=5,mode=620 0 0 < tmpfs /dev/shm tmpfs rw 0 0 < tmpfs /var/run tmpfs rw,mode=755 0 0 < tmpfs /var/lock tmpfs rw 0 0 --- > none /proc proc rw,nosuid,noexec,nodiratime 0 0 > none /sys sysfs rw 0 0 > none /var/run tmpfs rw 0 0 > none /var/lock tmpfs rw 0 0 > none /dev/pts devpts rw,mode=600 0 0 > none /dev/shm tmpfs rw 0 0 > none /var/run tmpfs rw 0 0 > simfs /var/lock simfs rw 0 0 none of these are mounted back in the same mount type.
