The important change here is to xlu_disk_parse to correctly set format == EMPTY
for CDROM devices which are empty. Test cases are added which check for
correctness here.
xend accepts ',hdc:cdrom,r'[0] as an empty CDROM drive however this is not
consistent with the xl syntax in docs/misc/xl-disk-configuration.txt which
requires ',,hdc:cdrom,r' (the additional positional paramter is the format).
I'm not sure if/how this can be fixed. Note that xend does not accept
',,hdc:cdrom,r'
There are several incidental cleanups included the the cdrom-{insert,eject}
commands:
- add a dry-run mode
- use the non-deprecated disk specification syntax
- check for and report errors from libxl_cdrom_insert

All of the other "list" verbs are of the form "$noun-list". For
example: "pci-list", "vcpu-list", "network-list", "block-list", etc.
Additionally, many people have well trained muscle memory from years
of typing "xm li". "xl li" was ambiguous due to "xl list-vm", thus
resulting in "command not implemented".
Finally, this command was missing from the xl man page.

xl remus acts as a frontend to enable remus for a given domain.
* At the moment, only memory checkpointing and blackhole replication is
supported. Support for disk checkpointing and network buffering will
be added in future.
* Replication is done over ssh connection currently (like live migration
with xl). Future versions will have an option to use simple tcp socket
based replication channel (for both Remus & live migration).

Dan Magenheimer explains in <4c2f7fca-dda2-4598-aaab-3a6a3fe532cd@default>:
I think the tmem_destroy functionality pre-dates the
existence of tmem "freeable" memory* and was a way for
a toolset to force the hypervisor to free up the hypervisor
memory used by some or all ephemeral tmem pools. Once the
tmem allocation/free process was directly linked into
alloc_heap_pages() in the hypervisor (see call to
tmem_relinquish_pages()), this forcing function was
no longer needed.
So, bottom line, I *think* it can be ripped out, or at least
for now removed from the definition of the stable xl API/UI.
The libxl.c routine libxl_tmem_destroy() could also be
removed if you like, but I guess I'd prefer to leave the
lower level droppings in xc.c and in the hypervisor in case
I am misremembering.
Accordingly remove this interface from libxl and xl but don't touch libxc or
the hypervisor.
This is the only libxl_tmem_* function which might potentially have required
conversion to be asynchronous and which therefore might have been a potential
API stability concern.

otherwise support is completely removed.

The user interfaces for cpupools are extended to support numa machines:
- xl cpupool-create supports now specifying a node list instead of a cpu list.
The new cpupool will be created with all free cpus of the specified numa
nodes.
- xl cpupool-cpu-remove and xl cpupool-cpu-add can take a node number instead
of a cpu number. Using 'node:1' for the cpu parameter will, depending on
the operation, either remove all cpus of node 1 in the specified cpupool,
or add all free cpus of node 1 to the cpupool.
libxl is extended with the following functions to support this feature:
int libxl_cpupool_cpuadd_node(libxl_ctx *ctx, uint32_t poolid, int node, int *cpus)
int libxl_cpupool_cpuremove_node(libxl_ctx *ctx, uint32_t poolid, int node, int *cpus)

XL sub-commands are expected to parse their arguments relative to the
global variable "optind" rather than treating argc+argv as zero
based. This is because the argc+argv passed to sub-commands include
the entire original command line, not just the sub command specific bits.
Not all commands do this and they are therefore broken if the user
uses "xl -v command", correct such problems
dump-core:
- did not handle "-h" option.
{network,network2,block}-{attach,list,detach} :
- handled arguments without reference to optind
- checked number of arguments before processing getopt loop,
breaking "-h" option handling
An example of the breakage:
# xl -v block-list d32-2
Vdev BE handle state evt-ch ring-ref BE-path
block-list is an invalid domain identifier

This patch implements the new protocol for handling pv consoles and
emulated serials as described in the document docs/misc/console.txt.
The changes are:
- xenconsoled: do not write the pty under serial in xenstore if
xenconsoled is handling a consolepath;
- xenconsole: implement support for an explicit console type parameter;
the parameter can be "pv", to specify that the user wants to
connect to a pv console, or "serial", to specify that the user wants to
connect to an emulated serial. If the type parameter hasn't been
specified be the user, xenconsole tries to guess which type of console
it has to connect to, defaulting to pv console for pv guests and
emulated serial for hvm guests.
- xenconsole: use the new xenstore paths;
- libxl: rename libxl_console_constype to libxl_console_consback:
constype is used to to specify whether qemu or xenconsoled provides the
backend, so I renamed it to libxl_console_consback to make it more
obvious that we are talking about backends;
- libxl: add a new libxl_console_constype to specify if the console is
an emulated serial or a pv console;
- libxl: support the new xenconsole "type" command line parameter;
- libxl: use the "output" node under console in xenstore to tell qemu
where do we want the output of this pv console to go;
- remove the legacy "serialpath" from xenconsoled altogether
