Oracle VM for SPARC also known as LDOM is a hypervisor used to virtualize the Oracle Solaris environment on T & M series Oracle/ Fujitsu Hardware. This article will walk through to configure the VNIC with specific VLAN number for guest LDOMs. Before getting into the VLAN part, you must understand the virtual networking on […]

LDOM – Memory / CPU Reallocation on Hard Partitioning
In LDOM , we can’t dynamically remove/add memory resource when the resources are physically bound. This will make hard-time for administrator and application owners where we need to bring down the guest domain every-time when you re-reconfigure memory resources. Normally Oracle Super-cluster servers are pre-configured with Hard Partitioning using the LDOM virtualization. In typical LDOM method […]
LDOM – How to find the physical Memory size ?
In UnixArena,we have talked more about LDOM aka Oracle VM for SPARC.But this article will provide the solution to identify the installed physical memory of the server from control domain. There is no direct command available to find out the total physical memory and un-allocated memory from control domain.Once you have set the resources limit […]
LDOM console write access issue – Solaris
Now a days i have mostly dealing with oracle VM for SPARC on T-4 servers.(LDOM). As we all know that hardware console can be writable for only one user at a time and if you take the second session , it will automatically connect in read only mode unless you use the force option. The […]
Oracle VM SPARC – LDOM configuration Backup and Restore
Oracle VM for SPARC configuration can be backed up in XML file and it can be restored it whenever required.This configuration backup will be very useful for future rebuilding. It also provides the option to take the backup of particular domain and that can be restored using ldm add-domain command.In this article we will how […]
How to Remove Logical Domains and Services ? Oracle VM for SPARC
Destroying the infrastructure is a easy task in all the environments.In oracle VM for SPARC also ,you can easily remove the guest domains in few seconds.

How to Add the Same ISO image file in Multiple LDOMS ?
In oracle VM for SPARC (LDOM), you need to attach the ISO file to each logical domain, for the first time operating system installation. If you have pre-configured jumpstart , You can use it for the guest domain operating system installation. If you don’t have jumpstart,then you need to install it using the ISO image. […]
How to perform Live domain migration on LDOM ? Oracle VM SPARC
In Oracle VM for SPARC,we can migrate the guest domains to another system without any downtime. This is similar to vmotion on VMware ESXi. This feature provides the operational flexibility to the customers who don’t want the system to be down for system maintenance.Prior to the system maintenance ,we can easily move the guest domains to […]
How to Dynamically add the resources in Oracle VM for SPARC ?
The beauty of LDOM or Oracle VM for SPARC is that resources can be dynamically added or removed from the domains(Primary/Guest). This will help you to perform the load balancing between the guest domains on the physical server. Dynamic resource allocation is only possible if the guest domain operating system is booted.If you add the resource during […]
How to Configure the I/O Domain on Oracle VM for SPARC ?
If you allow any of the guest domain or control domain to access the any I/O (PCI) cards directly from the hardware ,usually that domain is called I/O domain or root domain.By default, two virtual I/O services that you need to configure on primary domain to provide the I/O to the guest domains.One is virtual […]
