2. Brief about Primary/Control Domain ?
- It Controls the Oracle VM and also called as Primary domain.
- Used to configure server resources and guest domains and Provides virtual console services.
- Logical domain Manager installed only on Control domain.
- Control domain normally act as Service domain.
- For more reference "How to Configure Primary or Control Domain."
- Service domain Provides virtual device services to Guest Domain.
- It provides Virtual Disk Services.
- It provides Virtual Console Services.
- It provides Virtual network Switches.
- For more reference "How to Configure Service Domain"
- Guest domain uses only virtual services.
- Guest domain where our OS is installed.
- Get the services from service domain in order to run application and user services.
- Guest domain can be a I/O Domain.
- For more reference "How to Configure Logical/Guest Domain"
- I/O Domain where we are getting phyiscal I/O device access directly.
- I/O device which connects PCI bus, such as local network interface, disk drives and PCI adapters.
- For more reference "How to Configure I/O Domain"
