Migration Restrictions for Setting perf-counters
Take care when performing migrations of domains that have the perf-counters property value set.
Before you perform the migration of a domain that has the perf-counters property value set to global, ensure that no other domain on the target machine has the perf-counters property set to global.
During a migration operation, the perf-counters property is treated differently based on whether the performance access capability is available on the source machine, the target machine, or both.
The perf-counters property value is treated as follows:
-
Source machine only. The perf-counters property value is not propagated to the target machine.
-
Target machine only. The perf-counters property value on the machine to be migrated is updated to be equivalent to
perf-counters=
. -
Source and target machines. The perf-counters property value is propogated from the domain to be migrated to the migrated domain on the target machine.
For more information about the perf-counters property, see Using Perf-Counter Properties and the ldm
(8) man page.
