libvirt/src/esx/esx_driver.c
Geoff Hickey 6c8adeb41a esx: Support for disk-only and quiescing snapshots. 
Add support for creating disk-only (no memory) snapshots in esx, and
for quiescing the VM before taking the snapshot. The VMware API
supports these operations directly, so adding support to libvirt is
just a matter of setting the flags correctly when calling
VMware. VIR_DOMAIN_SNAPSHOT_CREATE_DISK_ONLY and
VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE are now valid flags for esx.

/*
* Parse a file name from a .vmx file and convert it to datastore path format
* if possbile. A .vmx file can contain file names in various formats:
*
* - A single name referencing a file in the same directory as the .vmx file:
*
* test1.vmdk
*
* - An absolute file name referencing a file in a datastore that is mounted at
* /vmfs/volumes/<datastore>:
*
* /vmfs/volumes/b24b7a78-9d82b4f5/test1/test1.vmdk
* /vmfs/volumes/datastore1/test1/test1.vmdk
*
* The actual mount directory is /vmfs/volumes/b24b7a78-9d82b4f5, the second
* form is a symlink to it using the datastore name. This is the typical
* setup on an ESX(i) server.
*
* - With GSX installed on Windows there are also Windows style file names
* including UNC file names:
*
* C:\Virtual Machines\test1\test1.vmdk
* \\nas1\storage1\test1\test1.vmdk
*
* - There might also be absolute file names referencing files outside of a
* datastore:
*
* /usr/lib/vmware/isoimages/linux.iso
*
* Such file names are left as is and are not converted to datastore path
* format because this is not possible.
*
* The datastore path format typically looks like this:
*
* [datastore1] test1/test1.vmdk
*
* Firstly this functions checks if the given file name contains a separator.
* If it doesn't then the referenced file is in the same directory as the .vmx
* file. The datastore name and directory of the .vmx file are passed to this
* function via the opaque parameter by the caller of virVMXParseConfig.
*
* Otherwise query for all known datastores and their mount directories. Then
* try to find a datastore with a mount directory that is a prefix to the given
* file name. This mechanism covers the Windows style file names too.
*
* The symlinks using the datastore name (/vmfs/volumes/datastore1) are an
* exception and need special handling. Parse the datastore name and use it
* to lookup the datastore by name to verify that it exists.

* URI format: {vpx|esx|gsx}://[<username>@]<hostname>[:<port>]/[<path>][?<query parameter>...]
* <path> = [<folder>/...]<datacenter>/[<folder>/...]<computeresource>[/<hostsystem>]
*
* If no port is specified the default port is set dependent on the scheme and
* transport parameter:
* - vpx+http 80
* - vpx+https 443
* - esx+http 80
* - esx+https 443
* - gsx+http 8222
* - gsx+https 8333
*
* For a vpx:// connection <path> references a host managed by the vCenter.
* In case the host is part of a cluster then <computeresource> is the cluster
* name. Otherwise <computeresource> and <hostsystem> are equal and the later
* can be omitted. As datacenters and computeresources can be organized in
* folders those have to be included in <path>.
*
* Optional query parameters:
* - transport={http|https}
* - vcenter={<vcenter>|*} only useful for an esx:// connection
* - no_verify={0|1}
* - auto_answer={0|1}
* - proxy=[{http|socks|socks4|socks4a|socks5}://]<hostname>[:<port>]
*
* If no transport parameter is specified https is used.
*
* The vcenter parameter is only necessary for migration, because the vCenter
* server is in charge to initiate a migration between two ESX hosts. The
* vcenter parameter can be set to an explicitly hostname or to *. If set to *,
* the driver will check if the ESX host is managed by a vCenter and connect to
* it. If the ESX host is not managed by a vCenter an error is reported.
*
* If the no_verify parameter is set to 1, this disables libcurl client checks
* of the server's certificate. The default value it 0.
*
* If the auto_answer parameter is set to 1, the driver will respond to all
* virtual machine questions with the default answer, otherwise virtual machine
* questions will be reported as errors. The default value it 0.
*
* The proxy parameter allows to specify a proxy for to be used by libcurl.
* The default for the optional <type> part is http and socks is synonymous for
* socks5. The optional <port> part allows to override the default port 1080.
