9.3.1 Dynamically Releasing Virtual I/O From a Logical Domain


9.3.1 Dynamically Releasing Virtual I/O From a Logical Domain
The operation of dynamically releasing and removing virtual I/O from a logical domain must be performed from the control domain.
Before removing the virtual I/O, confirm that it is not being used by the logical domain. For details, see the manual for the software being used.
Figure 9-1  Removing Virtual I/O
Figure 9-1 Removing Virtual I/O
Table 9-2 lists the procedure for dynamically releasing virtual I/O.
Table 9-2  Procedure for Dynamically Releasing Virtual I/O
Step Operation Description Execution Location Command Used
1 Checking the virtual I/O assigned to a logical domain, in Oracle Solaris on the control domain Control domain primary# ldm list-bindings <‌domain-name>‌
2 Removing the virtual I/O from the logical domain, in Oracle Solaris on the control domain Control domain To remove the virtual network interface
primary# ldm remove-vnet <‌if-name>‌ <‌domain-name>‌
To remove a virtual disk
primary# ldm remove-vdisk <‌if-name>‌ <‌domain-name>‌
3 Checking the status of the logical domain from which the virtual I/O was removed, in Oracle Solaris on the control domain Control domain primary# ldm list-bindings <‌domain-name>‌
The following example executes the commands for removing the virtual network interface and virtual disk assigned to a logical domain guest.
  1. Check the resources assigned to the logical domain guest.
primary# ldm list-bindings guest
