8、各厂商虚拟化技术比较
SUN Logical Domains Limitations
û
The source and target machines must have the same processor type running at the same frequency

û
Full cores must be allocated for the migrated domain.

û
After a migration, CPU dynamic reconfiguration is disabled for the target domain until reboot.

û
Conditions in the guest domain that would cause a CPU DR removal to fail would also cause the migration attempt to fail. For example, processes bound to CPUs within the guest domain, or processor sets configured in the source logical domain, can cause a migration operation to fail.

SUN LDOMs Virtual I/O Dynamic Reconfiguration Limitations
û
Only virtual I/O devices can be added

û
No support for physical devices

û
No support for removing devices

û
No support for dynamic add/remove of memory
