LDOMS: Getting started

• Verify if LDOM is already installed
• svcs ldmd
• if not, install LDOM using the following command
• pkg install ldomsmanager
• Verify that primary domain exist
• ldm list primary

• Check if the primary domain have the required services
• ldm ldm list-services primary

• If services are not available in primary domain, add these services. Add a virtual disk server, virutal console concentrator and virutal switch to the primary domain. These virtual services must be created to use the control domain as a service domain and to create virtual devices for other domains.
• Create a virtual disk server to allow importing virtual disks into a logical domain
  
• ldm add-vds primary-vds0 primary
• Export physical disks as virtual disks . Later these disks can be assigned to guest domain
• ldm add-vdsdev /dev/rdsk/c3t0d1s2  c3t0d1s2@primary-vds0

• Verify that virtual disks has been added to virtual disk server by checking the VDS section of the following output
• ldm list-bindings

• Add a virtual console concentrator
• ldm add-vcc port-range=5000-5100 primary-vcc0 primary

• Find the primary network interface (dladm show-phys) and add a virtual switch associated with primary network card. Virtual switch service enables networking between virtual network (vnet) devices in logical domains. The following command creates vritual switch named primary-vsw0 on net0 interface in the primary domain
• ldm add-vsw net-dev=net0 primary-vsw0 primary

• Verify that vsw0 device is created by issue dlam show-phys command 
• # dladm show-phys
  LINK              MEDIA                STATE      SPEED  DUPLEX    DEVICE
  net1              Ethernet             unknown    0      unknown   igb1
  net4              Ethernet             up         10     full      usbecm2
  net3              Ethernet             unknown    0      unknown   igb3
  net0              Ethernet             up         1000   full      igb0
  net2              Ethernet             unknown    0      unknown   igb2
  net6              Ethernet             up         1000   full      vsw0
• Also , verify that switch is created over on net0 interface
• VSW
      NAME             MAC               NET-DEV   ID   DEVICE     LINKPROP   DEFAULT-VLAN-ID PVID VID                  MTU   MODE   INTER-VNET-LINK
      primary-vsw0     00:14:4f:fb:3f:ea net0      0    switch@0              1               1                         1500         on    
  

• Verify the services have been created by using the list-services command
• ldm list-services primary

• Remove some resources from primary domain so it can be allocated to guest domains. Configure the control domain with 32 virutal CPUs and 16GB of memory
• # ldm start-reconf primary
• # ldm set-vcpu 32 primary
• # ldm set-memory 16G primary
• # ldm set-crypto 4 primary

• Save the configuration and reboot the system
• ldm add-config initial
• ldm list-config
  
• init 6

• Enable the virtual network terminal server daemon to provide access to the virtual console to each logical domain
• svcadm enable vntsd
• svcs vntsd
  

• Create the guest domain ldom1 from the control domain. Assign 48 VCPUs and 24G of memory to it.
• # ldm create ldom1
• # ldm set-vcpu 48 ldom1
• # ldm set-memory 24G ldom1
• # ldm set-crypto 6 ldom1
• Assign the disk to your domain
• ldm add-vdisk pdisk c3t0d1s2@primary-vds0  ldom1 

•  Set auto-boot? and boot-device variables for the guest domain 
• ldm set-variable auto-boot\?=true ldom1
• ldm set-variable  boot-device=pdisk ldom1

• Assign vnet to the domain
• ldm add-vnet vnet1 primary-vsw0 ldom1
