      Description

      >Description of problem:

      After installation of vzctl 4.9.4-1 on Debian Wheezy ploop snaphosts not working any more.

      >How reproducible:

      Always

      >Steps to Reproduce:
      1. Install vzctl 4.9.1-1

      2. Set VE_LAYOUT=simfs in /etc/vz/vz.conf

      3. Create container with ploop layout:
      # vzctl create 1000 --ostemplate debian-7.0-minimal --config vswap-2g --layout ploop --diskspace 10g

      4. Check ploop support
      # vzlist -o ctid,layout
      1000 ploop
      # vzctl snapshot-list 1000

      5. Install vzctl 4.9.4-1
      5. Recheck ploop support
      # vzlist -o ctid,layout
      1000 simfs
      # vzctl snapshot-list 1000
      Snapshot feature is only available for ploop-based CTs


      >Actual results:

      # vzctl snapshot-list 1000
      Snapshot feature is only available for ploop-based CTs

      >Expected results:
      Snapshots should work after vzctl upgrade.

      >Host OS:
      Debian Wheezy 7.9 amd64

      >Guest OS:
      Debian Wheezy 7.9 amd64

      Problem exists due to added option in /etc/vz/conf/1000.conf during vzctl upgrade:
      # Upgrade Thu Sep 10 12:01:51 MSK 2015: Securing CT config by adding VE_LAYOUT=simfs
      VE_LAYOUT=simfs
