Logical Domains (LDoms) 1.1 is available

LDoms 1.1 was released just before Christmas and its available for download here!

LDoms 1.1 greatly expands the capabilities and performance of Sun servers with CoolThreads technology (UltraSPARC T1, UltraSPARC T2, and UltraSPARC T2 Plus systems).

LDoms 1.1 adds new features, such as:

  • Warm and Cold Migration
  • Network NIU Hybrid IO
  • VLAN Support for Virtual Network Interface and Virtual Switch
  • Public XML Interface and XMPP Connection with the Domain Manager
  • Virtual IO Dynamic Reconfiguration
  • Virtual Disk Multipathing and Failover
  • Virtual Switch Support for Link Aggregated Interfaces
  • iostat(1M) Support in Guest Domains
  • And dozens of other product improvements

I recommend reading Alex Chartre's LDoms 1.1 post for more specifics on the new features and for usage examples.

Included in the download are optional LDoms System Management Tools:

  • Ldoms Management Information Base (MIB)
  • libvirt for LDoms
