Commit fba6bc47 introduced the non-migratable invtsc feature,
breaking save/migration with host-model and host-passthrough.

On hosts with this feature present it was automatically included
in the CPU definition, regardless of QEMU support.

Commit de0aeafe stopped including it by default for host-model,
but failed to fix host-passthrough.

This commit ignores checking of CPU features with host-passthrough,
since we don't pass them to QEMU (only -cpu host is passed),
allowing domains using host-passthrough that were saved with
the broken version of libvirtd to be restored.

RDMA Live migration requires registering memory with the hardware, and
thus QEMU offers a new 'capability' to pre-register / mlock() the guest
memory in advance for higher RDMA performance before the migration
begins. This capability is disabled by default, which means QEMU will
register the memory with the hardware in an on-demand basis.

This patch exposes this capability with the following example usage:

virsh migrate --live --rdma-pin-all --migrateuri rdma://hostname domain qemu+ssh://hostname/systemSigned-off-by: NMichael R. Hines <mrhines@us.ibm.com>

This patch adds support for RDMA protocol in migration URIs.

USAGE: $ virsh migrate --live --migrateuri rdma://hostname domain qemu+ssh://hostname/system

Since libvirt runs QEMU in a pretty restricted environment, several
files needs to be added to cgroup_device_acl (in qemu.conf) for QEMU to
be able to access the host's infiniband hardware. Full documenation of
the feature can be found on QEMU wiki:

RDMA migration uses the 'setup' state in QEMU to optionally lock
all memory before the migration starts. The total time spent in
this state is exposed as VIR_DOMAIN_JOB_SETUP_TIME.

Upstream qemu 1.4 added some drive-mirror tunables not present
when it was first introduced in 1.3.  Management apps may want
to set these in some cases (for example, without tuning
granularity down to sector size, a copy may end up occupying
more bytes than the original because an entire cluster is
copied even when only a sector within the cluster is dirty,
although tuning it down results in more CPU time to do the
copy).  I haven't personally needed to use the parameters, but
since they exist, and since the new API supports virTypedParams,
we might as well expose them.

Since the tuning parameters aren't often used, and omitted from
the QMP command when unspecified, I think it is safe to rely on
qemu 1.3 to issue an error about them being unsupported, rather
than trying to create a new capability bit in libvirt.

Meanwhile, all versions of qemu from 1.4 to 2.1 have a bug where
a bad granularity (such as non-power-of-2) gives a poor message:
error: internal error: unable to execute QEMU command 'drive-mirror': Invalid parameter 'drive-virtio-disk0'

because of abuse of QERR_INVALID_PARAMETER (which is supposed to
name the parameter that was given a bad value, rather than the
value passed to some other parameter).  I don't see that a
capability check will help, so we'll just live with it (and it
has since been improved in upstream qemu).

After the previous commit, migration statistics on the source and

statistics. Let's send the result back so that the same data can be
queried on both sides of the migration.
Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

Total time of a migration and total downtime transfered from a source to
a destination host do not count with the transfer time to the
destination host and with the time elapsed before guest CPUs are
resumed. Thus, source libvirtd remembers when migration started and when
guest CPUs were paused. Both timestamps are transferred to destination
libvirtd which uses them to compute total migration time and total
downtime. Obviously, this requires the time to be synchronized between
the two hosts. The reported times are useless otherwise but they would
be equally useless if we didn't do this recomputation so don't lose
anything by doing it.

When QEMU fails during incoming migration after we successfully started
it (i.e., during Perform or Finish phase), we report a rather unhelpful
message

    Unable to read from monitor: Connection reset by peer

We already have a code that takes error messages from QEMU's error
output but we disable it once QEMU successfully starts. This patch
postpones this until the end of Finish phase during incoming migration
so that we can report a much better error message:

    internal error: early end of file from monitor: possible problem:
    Unknown savevm section or instance '0000:00:05.0/virtio-balloon' 0

Be consistent with naming of private defines. Also line up code
correctly in few places where the macro is used.

While reviewing the new virDomainBlockCopy API, Peter Krempa
pointed out that our existing design of using MiB/s for block
job bandwidth is rather coarse, especially since qemu tracks
it in bytes/s; so virDomainBlockCopy only accepts bytes/s.
But once the new API is implemented for qemu, we will be in
the situation where it is possible to set a value that cannot
be accurately reflected back to the user, because the existing
virDomainGetBlockJobInfo defaults to the coarser units.

Fortunately, we have an escape hatch; and one that has already
served us well in the past: we can use the flags argument to
specify which scale to use (see virDomainBlockResize for prior
art).  This patch fixes the query side of the API; made easier
by previous patches that split the query side out from the
modification code.  Later patches will address the virsh
interface, as well retrofitting all other blockjob APIs to
also accept a flag for toggling bandwidth units.

During a QEMU live migration several warning messages about job
handling could be written to syslog on the destination host:

"entering monitor without asking for a nested job is dangerous"

The messages are written because the job handling during migration
uses hard coded asyncJob values in several places that are incorrect.

This patch passes the required asyncJob value around and prevents
the warnings as well as any issues that the warnings may be referring
to.

In qemuMigrationToFile we enter the monitor multiple times and don't
check if the VM is still alive after returning form the monitor. Add the
checks to skip pieces of code in case the VM crashes while saving it's
state.

In the future we might need to track state of individual images. Move
the readonly and shared flags to the virStorageSource struct so that we
can keep them in a per-image basis.

To allow changing the name that is recorded in the top of the current
image chain used in a block pull/rebase operation, we need to specify
the backing name to qemu. This is done via the "backing-file" attribute
to the block-stream commad.

Replace:
if (virBufferError(&buf)) {
    virBufferFreeAndReset(&buf);
    virReportOOMError();
    ...
}

with:
if (virBufferCheckError(&buf) < 0)
    ...

This should not be a functional change (unless some callers
misused the virBuffer APIs - a different error would be reported
then)

My commit fba6bc47 iterated over the features in cpu definition
without checking if there is one.

Add suport for invariant TSC flag (CPUID 0x80000007, bit 8 of EDX).
If this flag is enabled, the TSC ticks at a constant rate across
all ACPI P-, C- and T-states.

This can be enabled by adding:
<feature name='invtsc'/>
to the <cpu> element.

Migration and saving the domain does not work with this flag.

As part of the work on backing chains, I'm finding that it would
be easier to directly manipulate chains of pointers (adding a
snapshot merely adjusts pointers to form the correct list) rather
than copy data from one struct to another.  This patch converts
domain disk source to be a pointer.

In this patch, the pointer is ALWAYS allocated (thanks in part to
the previous patch forwarding all disk def allocation through a
common point), and all other changse are just mechanical fallout of
the new type; there should be no functional change.  It is possible
that we may want to leave the pointer NULL for a cdrom with no
medium in a later patch, but as that requires a closer audit of the
source to ensure we don't fault on a null dereference, I didn't do
it here.

This is similar to the previous commit in that we need to explicitly
send migrate_cancel when libvirt detects an error other than those
reported by query-migrate. However, the possibility to hit such error is
pretty small.

When QEMU reports failed or cancelled migration, we don't need to send
it migrate_cancel QMP command. But in all other error paths, such as if
we detect broken connection to a destination daemon or something else
happens inside libvirt, we need to explicitly send migrate_cancel
command instead of relying on the migration to be implicitly cancelled
when destination QEMU is killed.

Because we were not doing so, one could end up with a paused domain
after failed migration.

For now, we set the migration URI via command line '--migrate_uri' or
construct the URI by looking up the dest host's hostname which could be
solved by DNS automatically.

But in cases the dest host have two or more NICs to reach, we may need to
send the migration data over a specific NIC which is different from the
automatically resolved one for some reason like performance, security, etc.
Thus we must explicitly specify the migrateuri in command line everytime,
but it is too troublesome if there are many such hosts (and don't forget
virt-manager).

This patch adds a configuration file option on dest host to save the
default value set which can be specified to a migration hostname or
one of this host's addresses used for transferring data, thus user doesn't
have to specify it in command line everytime.

When qemu driver is polling for migration to finish (in
qemuMigrationWaitForCompletion), it may happen that another job allowed
during migration is running and if it does not finish within 30 seconds,
migration would be cancelled because of that. However, we can just
ignore the timeout and let the waiting loop try again later.

If an event fired at the end of migration is ever implemented in QEMU,
we can just wait for the event instead of polling for migration status
and libvirt will behave consistently, i.e., migration won't be cancelled
in case another job started during migration takes long time to finish.

When EIO comes to qemu while it's replying to
qemuMigrationUpdateJobStatus(), qemu blocks, the migration of RAM can
complete in the meantime, and when qemu unblocks, it sends us
BLOCK_IO_ERROR plus migrations "status": "complete".  Even though we
act upon the BLOCK_IO_ERROR by setting the proper state of the domain,
the call still waits for the proper reply on monitor for query_migrate
and after it gets it, it checks that migration is completed and the
migration is finished.  This is what abort_on_error flag was meant for
(we can migrate with these errors, but this flag must inhibit such
behaviour).  Changing the order of the steps guarantees the flag works
properly.
