Migration Restrictions for Domains That Have a Large Number of Virtual Devices

Sometimes, migrating a domain that has a large number of virtual devices causes the control domain on the target machine to be less responsive than usual. During this time, ldm commands appear to hang and standard Oracle Solaris OS commands take longer to complete than usual.

This interruption is caused by virtual servers processing the large number of incoming virtual devices associated with the migrated domain. After this processing completes, the control domain returns to normal and any stalled ldm commands complete.

You can minimize this sort of interruption by limiting the number of virtual devices used by a domain to no more than 1000.
