Sun Microsystems has just released the maintenance update to VirtualBox product, so xVM VirtualBox 1.6.2 is available for download.
Looks like version 1.6.2 is well worth the upgrade, at least for 64-bit PCs. I'm also happy to see many of Linux and Solaris host-related fixes, the stability of VirtualBox has really improved since version 1.5.
Here's just a few things I like from the VirtualBox changelog:
- VMM: fixed starting of VMs with AMD-V enabled
- VMM: massive performance enhancements for AMD-V
- VMM: stability improvements for AMD-V on Windows hosts
- VMM: correctly detect AMD CPUs with erratum 170 (AMD-V)
- Shared Folders: several fixes (iTunes download, speed up browsing)
- NAT: don't crash if the guest sent a DHCPRELEASE message with an invalid IP address
- NAT: fixed ARP reply for the NAT gateway and for the NAT name server if the guest IP range was changed
- BIOS: allow to change the DMI informatiton (see chapter 9.13, Con'guring the BIOS DMI information, page 125)
- Linux hosts: fixed default runlevel for the kernel module helper script
- Solaris hosts: enabled support for VT-x and AMD-V
- Solaris hosts: dynamic loading of libdlpi fixes a problem where Solaris 10 was not able to start a VM
- Linux additions: fixed runlevels for kernel module helper scripts
- Linux additions: compatibility fixes with Linux 2.6.26
- Linux additions: fixed occasional guest kernel crash during unload of the vboxadd guest kernel module
