David Scott 0c09b6495e xl: add support for 'channels'
This adds support for channel declarations of the form:

 channel = [ "name=...,connection=...[,path=...][,backend=...]" ]

where 'name' is a label to identify the channel to the frontend.

If 'connection = pty' then the channel is connected to a pty in the
 backend domain
If 'connection = socket' then the channel is connected to a Unix domain
 socket given by 'path = ...' in the backend domain.

This patch also adds the command:

 xl channel-list <domain>

which allows the state of channels to be queried. In particular if
'connection=pty' this will show the path of the pty slave device.

Technology(CMT) feature.

The following two commands is to attach/detach the CMT feature
to/from a certain domain.

$ xl psr-cmt-attach domid
$ xl psr-cmt-detach domid

This command is to display the CMT information, such as L3 cache
occupancy.

Yang Hongyang 6a19ecf2f3 xl/remus: add a cmdline switch to disable disk replication
Disk replication is enabled by default. This patch adds a cmdline
switch to 'xl remus' command to explicitly disable disk replication.
A new boolean field 'diskbuf' is added to the libxl_domain_remus_info
structure to represent this configuration option inside libxl.

Note: Disabling disk replication requires enabling unsafe mode.

Yang Hongyang d2dec181db xl/remus: cmdline switches and config vars to control network buffering
Add two members in libxl_domain_remus_info:
    netbuf: whether netbuf is enabled
    netbufscript: the path of the script which will be run to setup
                  and tear down the guest's interface.

Add cmdline switches to 'xl remus' command to enable or disable
network buffering and a domain-specific hotplug script to setup
network buffering.

Add a new config var 'remus.default.netbufscript' to xl.conf, that
allows the user to override the default global script used to
setup network buffering.

Note: Network buffering is enabled by default. Disabling network
buffering requires enabling unsafe mode.

Yang Hongyang 6e9adc3284 xl/remus: cmdline switch to explicitly enable unsafe configurations
By default, network buffering and disk replication are enabled;
checkpoints are replicated to another standby VM.

This patch allows the user to disable any of these features by
explicitly specifying a 'run in unsafe mode' switch when invoking
the 'xl remus' command.  While running Remus in an unsafe mode
makes little sense under normal circumstances, it is useful to be
able to disable one or more features mentioned above for
testing/debugging/profiling purposes.

Unless this option is enabled, it will not be possible to
replicate memory checkpoints to /dev/null (blackhole replication),
disable network buffering or disk replication.

As a starter, the use of blackhole replication now requires that
the unsafe mode be enabled. Subsequent patches will add support
for disabling network buffering and disk replication in a similar
manner.

Paul Durrant 88f30bcdb5 x86/viridian: Add partition time reference counter MSR support
This patch optionally re-instates support for the partition time reference
counter that was previously introduced by commit
e36cd2cdc9 and reverted by commit
1cd4fab14c. The previous implementation was
non-optional and flawed.

This implementation uses the tsc of vcpu0, which is preserved across
save/restore as part of the architectural state, and then converts that
to a 100ns tick using the domain's tsc_khz.

Paul Durrant 84bfbd5d75 x86/viridian: Re-purpose the HVM parameter to be a feature mask
The following commits introduced the time reference counter MSR and
TSC/APIC frequency MSRs into the viridian feature set respectively:

e36cd2cdc9
84657efd91

The time reference counter MSR feature was then reverted by commit

1cd4fab14c

because a flaw in the implementation meant the counter was reset on
migration.

All of these changes were made without any addtional options being
added to the VM configuration, or any compatibility checks being made
in the domain save/restore code. Hence setting the single boolean
'viridian' option in the VM configuration yields a different set of
features depending on which version of Xen the VM is started on, and the
feature set can change across migration (so new MSRs can magically appear).

This patch grandfathers in the current viridian features set and calls them
the 'base' and 'freq' feature sets. HVM_PARAM_VIRIDIAN is re-purposed as
a feature mask. The hypervisor has only ever allowed it ot be set to 0
or 1, so the presence of the base and freq sets are indicated by setting
bit 0. The freq set can then be turned off by setting bit 1, thus
restoring the pre-Xen-4.4 base set. Newly implemented viridian features
can be optionally enabled in future by setting further bits.

The viridian option in xl.cfg(5) has also been changed to a list so
that the sets can be individually enabled or disabled. For compatibility,
if the option is specified as a boolean, then a true (1) value will enable
the base and freq sets and a false (0) value will not enable any
enlightenments.

This patch also alters the allowed write accesses to HVM_PARAM_VIRIDIAN.
Currently there is nothing to stop the guest writing this value (which,
while harmless to anything else, should not happen) and nothing to
stop a toolstack from setting the value back to zero whilst the guest is
running, causing CPUID leaves to disappear and MSR accesses to start
causing GPFs in the guest. Both of these possibilities are now disallowed:
Once the parameter is set to a non-zero value it may not be modified (only
re-written with the same value), and guests no longer have any write
access.

Wei Liu e6afc7063a xl: use libxl_retrieve_domain_configuration and JSON format
Before this change, xl stores domain configuration in "xl" format, which
is in fact a verbatim copy of user supplied domain config.

Now libxl provides a new API to retrieve domain configuration, switch to
that new API, store configuration in JSON format.

Tests done so far (xl.{new,old} denotes xl with{,out} "libxl-json"
support):

1. xl.new create then xl.new save, hexdump saved file: domain config
   saved in JSON format
2. xl.new create, xl.new save then xl.old restore: failed on
   mandatory flag check
3. xl.new create, xl.new save then xl.new restore: succeeded
4. xl.old create, xl.old save then xl.new restore: succeeded
5. xl.new create then local migrate, receiving end xl.new: succeeded
6. xl.old create then local migrate, receiving end xl.new: succeeded

Note that "xl" config is still supported and handled when restarting a
domain. "xl" config file takes precedence over "libxl-json" in that
case, so that user who uses "config-update" to store new config file
won't have regression. All other scenarios (migration, domain listing
etc.) now use the new API.

Lastly, print out warning when users invoke "config-update" to
discourage them from using this command.

Dario Faggioli 705fad1227 libxl: automatic NUMA placement affects soft affinity
vCPU soft affinity and NUMA-aware scheduling does not have
to be related. However, soft affinity is how NUMA-aware
scheduling is actually implemented, and therefore, by default,
the results of automatic NUMA placement (at VM creation time)
are also used to set the soft affinity of all the vCPUs of
the domain.

Of course, this only happens if automatic NUMA placement is
enabled and actually takes place (for instance, if the user
does not specify any hard and soft affiniy in the xl config
file).

This also takes care of the vice-versa, i.e., don't trigger
automatic placement if the config file specifies either an
hard (the check for which was already there) or a soft (the
check for which is introduced by this commit) affinity.

Dario Faggioli 3d00662816 libxl/xl: make it possible to specify soft-affinity in domain config file
To do so, we add the vcpu_soft_affinity array to build_info, and
treat it much like vcpu_hard_affinity. The new config option is
called "cpus_soft".

Note that the vcpu_hard_affinity array, introduced in a previous
patch, and the vcpu_soft_affinity array, introduced here, share
the same LIBXL_HAVE_xxx macro, in libxl.h. That is called
LIBXL_HAVE_BUILDINFO_VCPU_AFFINITY_ARRAYS, and was introduced
together with vcpu_hard_affinity, but only inside a comment.
In this change, we uncomment, and hence properly define it.

In order to avoid having to issue separate calls to
libxl_set_vcpuaffinity() (one for hard affinity and one for soft
affinity) in libxl__build_pre(), in case the caller uses
b_info->cpumap (for the former) and b_info->vcpu_soft_affinity (for
the latter), we also set (again!) a new default for b_info->cpumap.
This allows, from this change on, to always and only deal with
b_info->vcpu_hard_affinity all around libxl internals.

Dario Faggioli af589e1a9c xl: move away from the use of cpumap for hard affinity
and start using the vcpu_hard_affinity array instead. This is done
as when, in a subsequent patch ("libxl/xl: make it possible to

to deal with soft affinity, code can be shared.

This change also enables more advanced VCPU to PCPU (hard, for now)
affinity specification, in case a list is used, like:

      cpus = ["3-4", "2-6,^4"]

What it means is that VCPU 0 must be pinned to PCPU 3,4 and VCPU 1
to PCPUs 2,3,5,6 (before this change, cpus=[xx, yy] only supported
single values). Of course, the old (e.g., cpus=[2, 3]) syntax

Dario Faggioli 7e474ba61c xl: enable getting and setting soft affinity
Getting happens via `xl vcpu-list', which now looks like this:

 # xl vcpu-list -s
 Name       ID VCPU CPU State Time(s) Affinity (Hard / Soft)
 Domain-0   0     0  11  -b-     5.4  8-15 / all
 Domain-0   0     1  11  -b-     1.0  8-15 / all
 Domain-0   0    14  13  -b-     1.4  8-15 / all

 vm-test    3     0   4  -b-     2.5  0-12 / 0-7
 vm-test    3     1   0  -b-     3.2  0-12 / 0-7

Setting happens by specifying two pCPU masks to the `xl vcpu-pin'
command, the first one will be hard affinity, the second soft
affinity. If only one mask is specified, it is only hard affinity
that is affected. To change only soft affinity, '-' can be used
as the hard affinity mask parameter, and it will be left alone.

xl manual page is updated accordingly.

minor functional regression but it's very easy to work around.

The rationale behind this change is that, this option is actually not
part of domain configuration. It just affects whether a vncviewer
should be automatically spawn, but has nothing to do with how a domain
should be constructed. And this option is also bogus, considering if you
migrate a domain to a remote host and the receiver spawns a vncviewer on
the receiving side then it either dies silently or occupies resource.

The man page mentions passing config snippets key=val in xl create.
Unfortunately, the config syntax contain characters which are
interpreted (and often discarded) by the shell before getting passed
in, resulting in a parsing error.

For example:

xl create hvm.cfg cpus="0-3"

The shell will eat the quotes and pass 'cpus=0-3' to xl, which won't
parse properly without the quotes.

Mention this in the man page, and recommend the use of single quotes, as well
as separating multiple arguments with a semicolon, thus:

xl create hvm.cfg 'cpus="0-3"; pci=["1.0","1.1"]'

George Dunlap e3df28fac3 xl: Add "seize" option to PCI devices
The "seize" option tells the toolstack to attempt to automatically
unbind devices and re-bind them to the pciback driver.  This should
make creating VMs that habitually use pass-through (such as driver domain
VMs and gaming VMs) easier to use and manage.

[Whitespace error fixed by iwj.]

Roger Pau Monne d1cb516db2 libxl: create a local xenstore libxl and device-model dir for guests
If libxl is executed inside a guest domain it needs write access to
the local libxl xenstore dir (/local/<domid>/libxl) to store internal
data. This also applies to Qemu which needs a
/local/<domid>/device-model xenstore directory.

This patch creates the mentioned directories for each guest launched
from libxl.

Add the 'max_event_channels' option to the xl configuration file to
limit the number of event channels that domain may use.

Plumb this option through to libxl via a new libxl_build_info field
and call xc_domain_set_max_evtchn() in the post build stage of domain
creation.

A new LIBXL_HAVE_BUILDINFO_EVENT_CHANNELS #define indicates that this
new field is available.

The default value of 1023 limits the domain to using the minimum
amount of global mapping pages and at most 5 xenheap pages.

Since d06b1bf169 ('libxl: automatic placement
deals with node-affinity') it is no longer true that, if no "cpus=" option
is specified, xl picks up some pCPUs by default and pin the domain there.

In fact, it is the NUMA node-affinity that is affected by automatic
placement, not vCPU to pCPU pinning.

Update the xl config file documenation accordingly, as it seems to have
been forgotten at that time.
