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.

Detail: Undefine VM after migration. Lingering domain definitions cause
migrations back to the original host to fail, since domain already exists.

deleted NFS pools, causing failures when defining new storage pools. Sometimes
a storage pool has never been used on a host, and getStoragePool fails when
copying templates or in storage migration. deleteStoragePool(pool) often fails
silently, leaving no pool defined in libvirt, but a mountpoint left behind.
This patch handles some of these exceptions and brings forward any issues via
logging.

The collection of network usage from VPC virtual router on KVM does not work,
because there is no corresponding procedure to deal with VPC virtual router
(cmd.isForVpc() = true).

cloud-defined resources on the host has caused various problems. As a backward
compatible fix, if an existing pool with a different name collides with a pool
being created (by path), the pool will be redefined with the name cloudstack
knows about. This is actually what brought up the bug, a persisted storage pool
cloudstack wasn't managing.

Detail: When we stop a VM, it's definition is no longer valid. Therefore, we
need to catch the exception thrown from libvirt in trying to lookup a
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.
