Add test for hsqueeze compression

In this example cluster, there are 6 nodes with
capacity for 4 instances each, holding a total
of 8 instances. So even after turning off 2 nodes
and rebalancing, every node still has capacity for
2 instances.

Add htools shell test for VCPU handling

This tests that VCPUs used by both instances and node OS are correctly
accounted in allocation.

Add test for the --full-evacuation option

In this example cluster, there are four pairs of nodes, each hosting
two instances. Each node has disk capacity for an additional instance.
Therefore, for normal online rolling reboots, there are two node groups,...

Add test for shrink heuristics over different resources

In this example, memory prevents adding more than one instance on
the first node. Yet, on the other nodes, 2 instances can be placed
each, if disks are shrunk appropriately. This, however, requires
to courageous decision to shrink disks next, even though more nodes...

Add a test for hspace to respect instance policy

In this example, the instance policy for disks prevents allocation
of more than one instance per node. The test verifies that tiered
allocation still respects this and doesn't attempt to place policy
violating instances on the cluster....

htools cluster score takes spindles into account

When exclusive storage is enabled, spindles are used instead of disk space
to compute the cluster score.

Comments and variable names in computePDsk has been changed to match the
actual code.

Unit tests for spindles and exclusive storage in htools

Everything should work the same when exclusive storage is active, as
spindles are not yet handled as a resource. A new test has been added for
the interactions between spindles and policies.

Parse NIC data from allocation request in hail

Add a NIC type and extend the Instance type by a list of NIC's. Parse
the NIC's in allocation requests and store them for now. Later patches
will make use of this field in order to ensure that the requested

Parse node group networks

Extend the Group by the network ids it is connected to. Adapt
the IAlloc backend such that the networks are parsed correctly.
This also required the adaption of test data.

Test for hroller taking non-redundant instances into account

The example cluster consists of 6 nodes, each hosting 2 instances and
having capacity for 3. So, while the drbd-induced graph consists of
only insulated nodes, no more than two nodes can be rebooted at the...

Add a test demonstrating the --node-tags option of hroller

The example is a cluster of 6 nodes, paired into 3 group by three
instances. So the whole cluster would need two reboot groups. The two

Add multiple min/max specs in instance policy

Now instance policies can contain more than one min/max specs. This is the

This is a big patch, but changing the type of a configuration item requires...

Adapt test data to changed ipolicy format

The test data for hail allocating a multi-disk instance was
