</pre><p>This function allows you to read the contents of a domain's
disk device.
Typical uses for this are to determine if the domain has
written a Master Boot Record (indicating that the domain
has completed installation), or to try to work out the state
of the domain's filesystems.
(Note that in the local case you might try to open the
block device or file directly, but that won't work in the
remote case, nor if you don't have sufficient permission.
Hence the need for this call).
'path' must be a device or file corresponding to the domain.
In other words it must be the precise string returned in
a <disk><source dev='...'/></disk> from
virDomainGetXMLDesc.
'offset' and 'size' represent an area which must lie entirely
within the device or file. 'size' may be 0 to test if the
call would succeed.
'buffer' is the return buffer and must be at least 'size' bytes.
NB. The remote driver imposes a 64K byte limit on 'size'.

connection you should split large requests to <= 65536 bytes.</p><div class="variablelist"><table border="0"><col align="left" /><tbody><tr><td><span class="term"><i><tt>dom</tt></i>:</span></td><td>pointer to the domain object</td></tr><tr><td><span class="term"><i><tt>path</tt></i>:</span></td><td>path to the block device</td></tr><tr><td><span class="term"><i><tt>offset</tt></i>:</span></td><td>offset within block device</td></tr><tr><td><span class="term"><i><tt>size</tt></i>:</span></td><td>size to read</td></tr><tr><td><span class="term"><i><tt>buffer</tt></i>:</span></td><td>return buffer (must be at least size bytes)</td></tr><tr><td><span class="term"><i><tt>flags</tt></i>:</span></td><td>unused, always pass 0</td></tr><tr><td><span class="term"><i><tt>Returns</tt></i>:</span></td><td>0 in case of success or -1 in case of failure. really 64 bits</td></tr></tbody></table></div><h3><a name="virDomainBlockStats" id="virDomainBlockStats"><code>virDomainBlockStats</code></a></h3><pre class="programlisting">int virDomainBlockStats (<a href="libvirt-libvirt.html#virDomainPtr">virDomainPtr</a> dom, <br /> const char * path, <br /> <a href="libvirt-libvirt.html#virDomainBlockStatsPtr">virDomainBlockStatsPtr</a> stats, <br /> size_t size)<br />

The memory which is read is controlled by the 'start', 'size'

parameters are interpreted as virtual memory addresses for
whichever task happens to be running on the domain at the
moment. Although this sounds haphazard it is in fact what
you want in order to read Linux kernel state, because it
ensures that pointers in the kernel image can be interpreted
coherently.
'buffer' is the return buffer and must be at least 'size' bytes.
'size' may be 0 to test if the call would succeed.
NB. The remote driver imposes a 64K byte limit on 'size'.

<a href="libvirt-libvirt.html#VIR_MIGRATE_PAUSED">VIR_MIGRATE_PAUSED</a> Leave the domain suspended on the remote side.
VIR_MIGRATE_TUNNELLED requires that <a href="libvirt-libvirt.html#VIR_MIGRATE_PEER2PEER">VIR_MIGRATE_PEER2PEER</a> be set.
Applications using the <a href="libvirt-libvirt.html#VIR_MIGRATE_PEER2PEER">VIR_MIGRATE_PEER2PEER</a> flag will probably
prefer to invoke virDomainMigrateToURI, avoiding the need to
open connection to the destination host themselves.
If a hypervisor supports renaming domains during migration,
then you may set the dname parameter to the new name (otherwise
it keeps the same name). If this is not supported by the
hypervisor, dname must be NULL or else you will get an error.
If the <a href="libvirt-libvirt.html#VIR_MIGRATE_PEER2PEER">VIR_MIGRATE_PEER2PEER</a> flag is set, the uri parameter
must be a valid libvirt connection URI, by which the source
libvirt driver can connect to the destination libvirt. If
omitted, the dconn connection object will be queried for its
current URI.
If the <a href="libvirt-libvirt.html#VIR_MIGRATE_PEER2PEER">VIR_MIGRATE_PEER2PEER</a> flag is NOT set, the URI parameter
takes a hypervisor specific format. The hypervisor capabilities
XML includes details of the support URI schemes. If omitted
the dconn will be asked for a default URI.
In either case it is typically only necessary to specify a
URI if the destination host has multiple interfaces and a
specific interface is required to transmit migration data.
The maximum bandwidth (in Mbps) that will be used to do migration
can be specified with the bandwidth parameter. If set to 0,
libvirt will choose a suitable default. Some hypervisors do
not support this feature and will return an error if bandwidth
is not 0.
To see which features are supported by the current hypervisor,
see virConnectGetCapabilities, /capabilities/host/migration_features.
There are many limitations on migration imposed by the underlying
technology - for example it may not be possible to migrate between
different processors even with the same architecture, or between
different types of hypervisor.</p><div class="variablelist"><table border="0"><col align="left" /><tbody><tr><td><span class="term"><i><tt>domain</tt></i>:</span></td><td>a domain object</td></tr><tr><td><span class="term"><i><tt>dconn</tt></i>:</span></td><td>destination host (a connection object)</td></tr><tr><td><span class="term"><i><tt>flags</tt></i>:</span></td><td>flags</td></tr><tr><td><span class="term"><i><tt>dname</tt></i>:</span></td><td>(optional) rename domain to this at destination</td></tr><tr><td><span class="term"><i><tt>uri</tt></i>:</span></td><td>(optional) dest hostname/URI as seen from the source host</td></tr><tr><td><span class="term"><i><tt>bandwidth</tt></i>:</span></td><td>(optional) specify migration bandwidth limit in Mbps</td></tr><tr><td><span class="term"><i><tt>Returns</tt></i>:</span></td><td>the new domain object if the migration was successful, or NULL in case of error.

If the <a href="libvirt-libvirt.html#VIR_MIGRATE_PEER2PEER">VIR_MIGRATE_PEER2PEER</a> flag is NOT set, the duri parameter
takes a hypervisor specific format. The uri_transports element of the
hypervisor capabilities XML includes details of the supported URI
schemes. Not all hypervisors will support this mode of migration, so
if the <a href="libvirt-libvirt.html#VIR_MIGRATE_PEER2PEER">VIR_MIGRATE_PEER2PEER</a> flag is not set, then it may be necessary
to use the alternative <a href="libvirt-libvirt.html#virDomainMigrate">virDomainMigrate</a> API providing and explicit
virConnectPtr for the destination host.
If the <a href="libvirt-libvirt.html#VIR_MIGRATE_PEER2PEER">VIR_MIGRATE_PEER2PEER</a> flag IS set, the duri parameter
must be a valid libvirt connection URI, by which the source
libvirt driver can connect to the destination libvirt.
VIR_MIGRATE_TUNNELLED requires that <a href="libvirt-libvirt.html#VIR_MIGRATE_PEER2PEER">VIR_MIGRATE_PEER2PEER</a> be set.
If a hypervisor supports renaming domains during migration,
the dname parameter specifies the new name for the domain.
Setting dname to NULL keeps the domain name the same. If domain
renaming is not supported by the hypervisor, dname must be NULL or
else an error will be returned.
The maximum bandwidth (in Mbps) that will be used to do migration
can be specified with the bandwidth parameter. If set to 0,
libvirt will choose a suitable default. Some hypervisors do
not support this feature and will return an error if bandwidth
