With Virtualbox 3.1 came the Live Migration feature as the virtualization industry’s first “Teleportation” capability, allowing running virtual machines to be moved between hosts — including different operating systems, types of computer (server to client) and CPUs (Intel to AMD).
Virtualbox 3.2 takes it further, and supports “Experimental support for Mac OS X guests”. We already published an guide on how to Install Snow Leopard on Virtualbox, now it’s seemed to get official, atleast starting with Virtualbox 3.2 Beta 1.
Let’s take a look at other major additions:
- Dynamic RAM allocation: Dynamically increase or decrease the amount of RAM used by a VM (64-bit hosts only) (aka Memory ballooning)
- New Hypervisor features: with both VT-x/AMD-V on 64-bit hosts, using large pages can improve performance. On VT-x, unrestricted guest execution is now supported.
- CPU hot-plugging for Linux (hot-add and hot-remove) and certain Windows guests (hot-add only)
- Delete snapshots while the VM is running
- Multi-monitor support
- USB tablet/keyboard Emulation via Guest Additions
- Better Remote Desktop: RDP video acceleration
- Advanced Networking: NAT engine configuration via API and VBoxManage
- Guest Additions: added support for executing guest applications from the host system
In addition, there are large number of bugfixes and performance improvements in 3D support, Mac OS X hosts, Linux, solaris guests, and Virtual machine manager.
On the other note, now Virtualbox has been rebranded to: Oracle VM Virtualbox.
