KVM hosts which are actuall up, but if their agents are shutdown should be put
in disconnected state. This would avoid getting the VMs HA'd and other commands
such as deploying a VM will exclude that host and save us from errors.
The improvement is that, we first try to contact the KVM host itself. If it fails
we assume that it's disconnected, and then ask its KVM neighbours if they can
check its status. If all of the KVM neighbours tell us that it's Down and we're
unable to reach the KVM host, then the host is possibly down. In case any of the
KVM neighbours tell us that it's Up but we're unable to reach the KVM host then
we can be sure that the agent is offline but the host is running.

KVMStoragePoolManager is a singleton in practice, any plugin

Clearly show if a volume is found and if not, that the pool is being refreshed
and the fetch is tried again.
Due to my commit b53a9dcc9f the chance of a volume
not being found is slightly bigger, but the performance gain is enormous on larger
deployments.
This is why we clearly have to log that we are refreshing the pool information
when a volume is not found.
It could be that a volume is created on host A and a few seconds later host B tries
to access the volume. In that case host B's libvirt doesn't know about the volume
yet and has to refresh the pool before it does.
On larger (especially RBD) storage pools this can take a lot of
time slowing operations like creating volumes down.
The getStorageStats command will still ask a pool to be refreshed so
that the management server has accurate information about the storage pools.
On larger deployments, with thousands of volumes in one pool, this should
significantly improve storage related operations
For ResizeVolume API command -
1. If hypervisor resource throws an exception, handle the NPE thrown by the job framework.
2. Improve user error message in case of RuntimeException by throwing the exception instead of 'Unexpected Exception'.
We don't need an external script to investigate the format of the RBD volume,
we only have to ask Libvirt to resize the volume and that will ask librbd to
do so.
In situations where libvirt lost the storage pool the KVM Agent will re-create the
storage pool in libvirt.
This could be then libvirt is restarted for example.
The object returned internally was missing essential information like the sourceDir
aka the Ceph pool, the monitor IPs, cephx information and such.
In this case the first operation on this newly created pool would fail. All operations
afterwards would succeed.
We used to create the snapshot after the copy from Secondary Storage,
but it could be that we never use the snapshot.
Now we check if the snapshot exists prior to performing the cloning operation
Since we use qemu-img to copy from RBD to Secondary Storage we no
longer have to force to RAW images, but can stick with QCOW2
When the snapshot backups are QCOW2 format they can easily be deployed
again when restoring from a backup
The KVMStorageProcessor no longer has a hardcoded if-statement which sets
RBD volumes to RAW, this is now handled in the LibvirtStorageAdapter
The Management Server still sends QCOW2 as format. That's a fix for later.

Added a new flag 'checkBeforeCleanup' to StopCommand based on which check is done to see if VM is running in HV host.
If VM is running then in this case it is not stopped and the operation bails out.
Also modified the MS code to call the StopCommand with appropriate value for the flag based on the context.
Currently it is only set to 'true' when called from the new vmsync logic based on powerstate of VM. For rest it
is set to 'false' meaning no change in behaviour.
This reduces the amount of time and storage it takes dramatically. We no longer
do a full copy, but a sparse copy. The destination image is still in RAW
format, but we only copy over used blocks.
Qemu is also better in doing this then us doing it in Java code.
Otherwise a RBDException will be thrown with the message that the snapshot
isn't protected.
modified: plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/storage/LibvirtStorageAdaptor.java
This saves the step of writing to a temporary image in /tmp first before
writing to RBD.
This is possible due to a new version in librbd. With the rbd_default_format
setting we can now force qemu-img to create format 2 RBD images.
This is available since Ceph version 0.67.5 (Dumpling).

With VirtIO enabled on KVM. FreeBSD 10 supports VirtIO for both the
network and the disks. This frees us from IDE and E1000 which should
also improve performance.
By default all network disks are in RAW format. Gluster works fine with
QCOW2 which has some advantages.
Disks are by default in QCOW2 format. It is possible to run into
a mismatch, where the disk is in QCOW2 format, but QEMU gets started
with format=raw. This causes the virtual machines to lockup on boot.
Failures to start a virtual machine can be verified by checking the log
of the virtual machine, and compare the output of 'qemu-img info'.
In /var/log/libvirt/qemu/<VM>.log find the URL for the drive:
-drive file=gluster+tcp://...,format=raw,..
Compare this with the 'qemu-img info' output of the same file, mounted
under /mnt/<pool-uuid>/<img-uuid>:
# qemu-img info /mnt/<pool-uuid>/<img-uuid>

This saves us a lot of code and libvirt is probably a better
place to do this.
libvirt-java now has the support we want, so we can now resize volumes
with libvirt.
(C)LVM volumes can't be resized using libvirt, so we have to
invoke a resize script for that.
By default the client_mount_timeout setting in librados is 300 seconds,
but that causes the connect to the Ceph cluster to block for 5 minutes
if the Ceph cluster is not available.
This patch is not ideal, but it mitigates the problem for now.
At a later point all this librados/librbd code should go back to libvirt
again, but the current versions of libvirt in the distributions are
to old for all the features we require.
For now this should prevent the CloudStack agent blocking for 5 minutes
when the Ceph cluster isn't available.
This is also tracked at the Ceph tracker: http://tracker.ceph.com/issues/6507
brought back up after being down for few hours,snapshot jobs do not get

I don't think host kernel version has any bearing on it. Original code
was tested with CentOS 6.3 and 6.4, but it seems to succeed or fail per-host,
e.g. a fast host might work and a slow host might not. I was getting intermittent
failures with ubuntu 12.04.3 prior to this patch.
These changes are a joint effort between Edison and I to refactor some
of the code around snapshotting VM volumes and creating
templates/volumes from VM volume snapshots. In general, we were working
towards allowing PrimaryDataStoreDrivers to create snapshots on primary
storage and not requiring the snapshots to be transferred to secondary
storage.
High level changes:
-Added uuid to NfsTO, SwiftTO & S3TO to cut down on the requirement of
PrimaryDataStoreTO and ImageStoreTO which don't really serve much of a
purpose
-Initial work towards enable reverting VM volume from snapshots
-Added hypervisor commands for introducing and forgetting new hypervisor

There still exist two issues after Edison's commits.
(1) Migration from new hosts to old hosts failed.
The bridge name on old host is set to cloudVirBr* if network.bridge.name.schema is set to 3.0 in /etc/cloudstack/agent/agent.properties, but the actual bridge name is breth*-* after running cloudstack-agent-upgrade.
(2) all ports of vms (Basic zone, or Advanced zone with security groups) on old hosts are open, because the iptables rules are binding to device (bridge) name which is changed by cloudstack-agent-upgrade.
After this, the KVM upgrade steps :
a. Install 4.2 cloudstack agent on each kvm host
b. Run "cloudstack-agent-upgrade". This script will upgrade all the existing bridge name to new bridge name, and update related firewall rules.
c. install a libvirt hook:

The migrate method from libvirt supports passing down a different XML for running

This enables the VNC to bind to the private IP Address of the hypervisor and during

RBD format 2 supports cloning (aka layering) where one base image can serve
as a parent image for multiple child images.
This enables fast deployment of a large amount of virtual machines, but it also
saves spaces on the Ceph cluster and improves performance due to better caching.
Qemu-img doesn't support RBD format 2 (yet), so to enable these functions the
RADOS/RBD Java bindings are required.
This patch also enables deployment of System VMs on RBD storage pools. Since we
no longer require a patchdisk for passing the boot arguments we are able to deploy
these VMs on RBD.
Detail: We do two strange things, #1, when a vm is created, we create the uuid
for the domain by converting the name into a uuid, then subsequently, any time
we look for a domain, we convert its name to a uuid and domainLookupByUUID. This
is an unnecessary obfuscation, so instead we just do a domainLookupByName. As
a bonus, we are now setting the domain's uuid to be the cloudstack uuid. It is
no longer used anywhere, but will be less confusing to admins. This shouldn't
affect upgrades, since we can always lookup existing VMs by name.

non-existent domain by UUID while trying to check if it's shut down.

Detail: A previous patch fixed an issue where we are defining VMs to persist
locally on KVM hosts, which can cause issues if the agent isn't running and
libvirt decides to start the VM unbeknownst to cloudstack. The previous patch
stopped defining VMs as persistent. This patch adds compatibility for existing
cloudstack environments, removing the persistent definition on stop if needed.

Detail: This gets rid of the patchdisk method of passing cmdline and
authorized_keys to KVM system VMs. It instead passes them to a virtio socket,
which the KVM guest reads from the character device /dev/vport0p1 during
cloud-early-config. Tested to work on CentOS 6.3 and Ubuntu 12.04. Should
work with even older versions of libvirt.

Current kvm agent will silently ignore many exception, and there's no
way to see what really happened. This patch will log in trace level log
that was silently ignored. And also, it will fix huge bare Exception
catch, which is very harmful because it also catches RuntimeException.
Detail: This device can be used for remotely controlling the system vms through
a local socket on the host. We will attempt to replace the KVM patchdisk with
it. Tested, successfully deploys VM, and if system vm has proper driver it
will create a /dev/vport0p1 device within the VM. We will be updating the
system VM in 4.2/5.0 and will support this.

We used to define domains persistent in libvirt, which caused XML definitions
to stay there after a reboot of the hypervisor.
We however don't do anything with those already defined domains, actually, we wipe
all defined domains when starting the agent.
Some users however reported that libvirt started these domains after a reboot
before the CloudStack agent was started.
By starting domains from the XML description and not defining them we prevent
them from ever being stored in libvirt.

Detail: Instead of using LibvirtStorageAdaptor for everything, you can create
your own storage adaptor and use it. We select storage adaptor based on storage
pool type, thus we needed to adjust LibvirtComputingResource to pass pool type
to everything in KVMStoragePoolManager. This in turn required that we pass the
info necessary to LibvirtComputingResource as well, so a few agent Commands were
modified.
Note this patch in and of itself shouldn't change any existing behavior, just
allow for new storage adaptors to be selected based on storage pool type.

Detail: Because of the way most other primary storage types work with cloudstack
(i.e. backing stores) CLVM actually copies the template to a local logical
volume on primary storage, then uses that. This causes all of your primary
storage to be littered with a copy of every template used. Since we're not
using these, dump the template direct to the newly created logical volume.
This is faster as well since the template is sparse; we're not creating a fat
template on primary storage and then copying that to a logical volume when we
deploy from template.

On kvm computing host, vifdriver.unplug will always fails (throws
LibvirtException) and network cleanup will not be called. This was
because the code first undefine the computing domain, and then tries to
query the destroyed machine definition to fetch NIC information. IMHO,
kvm plugin code rounds LibvirtException too much.

Cloudstack seems to let you create guest traffic types on multiple
physical networks. However, when I try this with KVM I end up always
bridging to whatever device is used for guest.network.device. This pulls
the traffic label (NicTO.getName()) and uses that bridge to ensure that
we get on the correct physical network, rather than just always using
the guest.network.device.
This also changes the bridge naming scheme from cloudVirBr + vlanid to
br + physicalinterface + "-" + vlanid. This is because we should be able
to support the same vlan numbers per physical network, and the previous
bridge name would not support this and collide.

The code is unable to detect an existing pool, because we use a random
UUID each time. New Libvirt doesn't allow multiple pools to be defined
to the same storage. This patch generates a UUID based on the storage
path, so that it can be detected as existing and reused. It also cleans
up no-op code and adjusts the naming of a few things to clean up any
confusion.

Since /root is r-x permissions, Java fails to mkdir /root/.ssh (even
though the agent is running as root) because it looks for the writable
permission. This patch modifies the 'chmod 700 /root/.ssh' shell command
that we already use into 'mkdir -m 700 /root/.ssh', to be able to create
the directory as root even though write permissions are not set on
/root. This seemed cleaner/safer than adding writable to /root.

We used to generate a UUID when this wasn't set, but since we aren't writing to
agent.properties anymore we have to make sure the UUID is persistent across restarts.
Libvirt can also return a bunch of emulators for eg ARM and S390
We filter those out since we do not support these architectures.
This way we don't try to start a x86_64 instance with a S390 emulator
Since we are using libvirt for handling our storage pools we should rely on that information as well.
Before fetching the capacity we refresh the pool so libvirt has the most up-to-date information.
This is not needed with newly created pools since libvirt does a refresh on creation.
