      NodeQuery: mark live fields as UNAVAIL for non-vm_capable nodes · effab4ca
      Iustin Pop authored 
      
Since we don't have the data per design, UNAVAIL is appropriate here,
while NODATA is not.

The patch also adds a comment: if we extend the live fields list to
contain other data in the future, we need to reevaluate this solution.

This should fix issue 143. The listing now shows (node2==ofline,
node3==not vm_capable):

  Node     DTotal     DFree    MTotal     MNode     MFree Pinst Sinst
  node1    698.6G    630.5G     32.0G      1.0G     30.0G     8     7
  node2 (offline) (offline) (offline) (offline) (offline)     9     4
  node3 (unavail) (unavail) (unavail) (unavail) (unavail)     0     0

      query: Change internal result computation · e2d188cc
      Iustin Pop authored 
      
While looking at the query library, I realized that while we have five
field statuses, making this a 5-dimensional space, four of them are
shrunk to a single possible value (None). Hence it should be possible to
convert this into a single value space plus extra 4 special constants.

This patch implements this, making (IMHO) the return value of normal
functions much simpler: you simply return the desired value, instead of
(QRFS_NORMAL, value); for the special results, you simply return
_FS_UNAVAIL, instead of (QRFS_UNAVAIL, None). This I believe does
simplify the code.

      KVM: Perform network configuration in Ganeti · 5d9bfd87
      Apollon Oikonomopoulos authored 
      
This patch introduces network configuration for KVM in Ganeti.

There are three problems with having KVM perform network configuration via ifup
scripts:
  a) Ganeti never gets to know the tap interface that is associated with an
     instance's NIC
  b) Migration of routed instances will cause network problems because the
     incoming KVM side configures the network as soon as it is spawned and not
     as soon as the migration finishes. This means that all routing
     configuration will be present in both, primary and secondary, nodes at the
     same time, possibly causing network disruption during the migration.
  c) We never get to know if the network configuration succeeded or not.

This patch moves network configuration from KVM to Ganeti, using KVM's ability
to receive already open tap devices as file descriptors.

_WriteNetScript is removed from hv_kvm.py, together with its unit tests.

Minor modifications are made to _ExecKVMRuntime to handle tap device
initialization. NIC <-> tap associations are stored under a new directory,
_ROOT_DIR/nic in a file-per-nic fashion.

The end-user semantics remain the same: The user can override the network
configuration by providing _KVM_NET_SCRIPT. If this is not present or
executable, the default constants.KVM_IFUP script is run.

      Check consistency of the class names and OP_ID · ff0d18e6
      Iustin Pop authored 
      
As the class names should be now consistent with the OP_IDs, we add a
check for wrongly-defined OP_IDs.

However, the future removal of the hand-coded OP_IDs will render this
obsolete, so this check is introduced just to make sure that the
previous renaming patches did the right job, and it will then be
removed.

The consistency checks require renaming the test opcodes, which were
using arbitrary names, depending on test author. They are now all
standardized on OpTest (local scope).
