</pre><p>This function allows you to read the contents of a domain's memory. The memory which is read is controlled by the 'start', 'size' and 'flags' parameters. If 'flags' is <a href="libvirt-libvirt.html#VIR_MEMORY_VIRTUAL">VIR_MEMORY_VIRTUAL</a> then the 'start' and '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'. For your program to be able to work reliably over a remote connection you should split large requests to &lt;= 65536 bytes.</p>

Flags may be one of more of the following: <a href="libvirt-libvirt.html#VIR_MIGRATE_LIVE">VIR_MIGRATE_LIVE</a> Attempt a live migration. 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. Since typically the two hypervisors connect directly to each other in order to perform the migration, you may need to specify a path from the source to the destination. This is the purpose of the uri parameter. If uri is NULL, then libvirt will try to find the best method. Uri may specify the hostname or IP address of the destination host as seen from the source. Or uri may be a URI giving transport, hostname, user, port, etc. in the usual form. Refer to driver documentation for the particular URIs supported. 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>
