After the next reboot of the OS
After a stop and start of the logical domain
Starting with the Logical Domains Manager 1.2 software, delayed reconfiguration operations are restricted to the control domain. For all other domains, you must stop the domain to modify the configuration unless the resource can be dynamically reconfigured.
When a delayed reconfiguration is in progress on the control domain, other reconfiguration requests for the control domain are deferred until it is rebooted, or stopped and started. Also, when a delayed reconfiguration is outstanding for the control domain, reconfiguration requests for other logical domains are severely restricted and will fail with an appropriate error message.
The Logical Domains Manager ldm cancel-operation reconf command cancels delayed reconfiguration operations on the control domain. You can list delayed reconfiguration operations by using the ldm list-domain command. For more information about how to use the delayed reconfiguration feature, see the ldm(1M) man page.
You cannot use the ldm cancel-operation reconf command if any other ldm remove-* commands have already performed a delayed reconfiguration operation on virtual I/O devices. The ldm cancel-operation reconf command fails in these circumstances.
