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).

xm supports the following syntax (in the config file) for
specific VCPU to PCPU mapping:
cpus = "0-3,5,^1" # all vcpus run on cpus 0,2,3,5
cpus = ["2", "3"] # VCPU0 runs on CPU2, VCPU1 runs on CPU3
Allow for the same in xl.
This fixes what happened in changeset 54000bca7a6a, which
introduced suppot for the `cpus=` option within xl, but used
both the list (cpus=[2, 3]) and the string (cpus="2,3") syntax
for achieving the same behaviour (pin all guest's vcpus to the
pcpus in the list/string).

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.

By default pciback only allows PV guests to write "known safe" values into
PCI config space. But many devices require writes to other areas of config
space in order to operate properly. One way to do that is with the "quirks"
interface, which specifies areas known safe to a particular device; the
other way is to mark a device as "permissive", which tells pciback to allow
all config space writes for that domain and device.
This adds a "permissive" flag to the libxl_pci struct and teaches libxl how
to write the appropriate value into sysfs to enable the permissive feature for
devices being passed through. It also adds the permissive config options either
on a per-device basis, or as a global option in the xl command-line.
Because of the potential stability and security implications of enabling
permissive, the flag is left off by default.

Move the sxp producing code off into a separate file. It is supported
for legacy reasons and needn't be updated other than the improve
compatibility with xm.
libxl_domain_config is not currently generated by the IDL (adding the
necessary support for Array types is on my to do list) so hand code
the json generation function for now.
Since this rather directly exposes a libxl data structure it's not
clear what sort of forward compatibility guarantees we can
make. However it seems like it should be as stable as libxl's own API
(which we are looking to stabilise)
