Fixes bug 1022681
If deleting the kernel/ramdisk fails because the files don't exist
anymore, then ignore the error and continue. This will ensure that the
instance will get destroyed properly even if the files were deleted
outside of nova.

Nova has additional pep8 "plugins" that they expect to run as part of the
gate. This patch will run tools/hacking.py instead of pep8 directly. Also,
it fixes the hacking violaions in contrib, plugins and smoketests.

Adds a call to retrieve the current uptime on a specific hypervisor.
This version of the patch only adds the XenAPI variant; other virt
drivers will raise a NotImplementedError until they implement the
get_host_uptime() method.

The kernel and ramdisk VDI manipulation code really has nothing to do
with Glance so it doesn't make a lot of sense for it to exist in the
Glance Dom0 plugin.
This patch refactors the code out to its own plugin and then applies a
few misc cleanups.
Change-Id: I363d54ea3c2d51aa6a6c1635b4fb59ebb9ce1fc0
The virt-layer code was refactored so that a dict was used to pass
around which VDIs are present. This code makes the Dom0 plugin return
that same data structure so we don't have to perform an extra conversion
step.
Change-Id: Ib4f1b0082138d233eb0c3873bbc553395510bc8d
`utils.py` was added by the Dom0 plugin refactoring but the
corresponding declaration in the SPEC file was forgotten.

Windows agent requires an argument of either 'agent' or 'xentools' to
the 'version' command. All we care about is 'agent', so add it. The
unix agent happily ignores the arg.

Instance types define disk names as root, swap and ephemeral. The
XenAPI driver however uses os, swap and ephemeral. Standardize on
calling them 'root' disks instead of 'os' disks.

Python 2.4's shlex implementation doesn't seem to like unicode.
This updates the XenServer migration plugin so it converts to
ascii before shlex'ing the rsync args.
Fixes OSAPI resizes when using XenServer.

Without this change, the glance plugin is pretty quiet about image
uploads. But it can definitely be helpful to debugging to have
information such as which glance server is handling the upload, how much
data was sent, and more information about the glance server response if
it was something other than 200 OK.

Looks like this fixes all HACKING problems that were around.

Ensures the calls in the xenhost plugin work when the host is in
a xenserver pool managed by the host aggregates feature.
Change-Id: I51ca6b9f6d0e8d86d53afde5bf46cfabde17a44e
this changeset introduces the following:
- refactoring around host-related operations for xenapi
- increased test coverage
- first cut at implementing host evacuation for a XS/XCP host
Change-Id: I8509cdde95f6777ecfa928663b0c4bedbccf5d38
This changeset addresses a number of issues found during testing:
- avoid name conflicts during aggregate creation (see db/* changes)
- avoid masking of XenAPI.Failure if pool-join fails (see plugins/* changes)
- preserve VM placement decisions made during scheduling (see xenapi/vmops.py)
- ensure plugins are called on the right hosts in XS pools (see xenapi_con.py)
- stores master uuid in aggregate metadata for use in VM live migration and
raise InvalidAction rather than Aggregate error if we attempt to remove
a mster (see xenapi/pool.py and compute/manager.py)
- clean-up of unit tests
Change-Id: I881a94d87efe1e81bd4f86667e75f5cbee50ce91
This commit introduces some clean-up/improvements on the current model
and api for host aggregates. It also introduces a first version of the
xenapi implementation. More precisely:
- it lays out the structure of the virt driver,
- it introduces compute and xenapi unit tests coverage,
- it deals with join/eject of pool master and slaves,
- it fixes xenapi_conn, when used in resource pool configurations
More commits to follow (to ensure that VM placement, networking setup,
performance metrics work just as well in cases where resource pools
are present). However, these may be outside the scope of this blueprint
and considered as ad-hoc bug fixes.

Implements blueprint fast-cloning-for-xenserver
1. use_cow_images flag is reused for xenserver to check if copy on write images should be used.
2. image-id is used to tag an image which has already been streamed from glance.
3. If cow is true, when an instance of an image is created for the first time on a given xenserver, the image is streamed from glance and copy on write disk is created for the instance.
4. For subsequent instance creation requests (of the same image), a copy on write disk is created from the base image that is already present on the host.
5. If cow is false, when an instance of an image is created for the first time on a host, the image is streamed from glance and its copy is made to create a virtual disk for the instance.
6. For subsequent instance creation requests, a copy of disk is made for creating the disk for the instance.
7. Snapshot creation code was updated to handle cow=true. Now there can be upto 3 disks in the chain. The base disk needs to be uploaded too.
8. Also added a cache_images flag. Depending on whether the flag is turned on on not, images will be cached on the host.

Provides two drivers for implementing security groups in xenapi:
1) domU driver that enforces security groups on the Openstack virtual appliance (use advised with FlatDHCP in HA mode)
2) dom0 driver that enforces security groups where VIFs are attached
Both drivers translate security groups into iptables rules.
Existing libvirt code has been refactored to reduce the amount of duplicated code to a minimum
Now Addressing reviewers's comments on style. Fixing issue spotted with snapshots

This patch implements resizing an instance to a smaller disk. It implements
this by copying the VDI and running e2resize, before transferring to the
new host.

Move openvswitch-nova to 23 in the boot order.
The openvswitch-nova init.d script used on XenServer has been set to run
at 96 in the boot order (i.e. very late). This is inconvenient, because it
means that it runs after the firstboot scripts, so if you want to do an
automated install of a compute VM, say, you can't rely on the Open vSwitch
rules being ready.
23 places it after the networking start up (9 through 14) and before the
firstboot scripts (24).

Currently the plugin uses httplib which does not handle redirects
natively. XenAPI plugins require Python 2.4+ so using httplib2
as far as I know is not a possibility.
(Patch Set 2) Oops, forgot to PEP8 before putting up for review.
(Patch Set 3) Updated logging to be more verbose as per Waldon
