      Add a variable to control what space is included in the xen_vg VG. · 2fbfc5dd
      Mike Hibler authored
      Setting LVM_FULLDISKONLY will effectively tell it to not use extra
      space on the system disk when constructing the VG used for vnode disk
      creation. This can affect performace for everybody, especially if it
      uses multiple little partitions on the system disk. However, this is
      turned off by default since, on our d710 nodes, most of the extra
      space is on the system disk. Setting this should be plumbed through
      to the user somehow so they can choose.

      Support for MBR v3 images in Xen VMs. · ef69e78a
      Mike Hibler authored
      If the Xen dom0 base image is properly (1M) aligned and the VM images
      are properly aligned as well, we should avoid or at least minimize any
      anomolous effects due to mismatches along the path involving the guest OS,
      guest disk layout, LVM LVs, LVM PVs, and the underlying physical disks.
      
      Also, random change to add a min size parameter to the findSpareDisks
      function. I was going to use this to avoid sucking up the little 3GB
      unused partition in MBR 3, but then decided against it.

      Changes to use pygrub as boot loader. · 1c8032c7
      Leigh B Stoller authored
      We were using pygrub to suck the kernel and ramdisk out before
      booting the guest, but doing that makes it impossible for for
      the guest to change its kernel and reboot.
      
      Other minor fixes.

      Various fixes: · 90cbd079
      Leigh B Stoller authored
      1. kpartx does not do its own locking, so must protect it from
         concurrent runs during setup.
      
      2. Allow mulitple XEN hosts (up to 4) to set up concurrently via new
         TBScriptLock() shared lock, but revert to exclusive lock if an
         image needs to created or modified.
      
      3. Convert root disk (XEN-STD) to a plain NDZ file from raw LVM bits,
         so that we get some benefit from the buffer cache.
