Windows hosts: fixed high CPU usage after resuming the host Solaris guest: fixed mouse integration for OpenSolaris 2009.06 Solaris host: fixed a preemption issue causing VMs to never start on Solaris Other fixes and improvements are listed as follows:
As for Linux fans, a workaround has been found for buggy graphics drivers showing a black VM window on recent distributions. On the Windows side only, Sun reveals, VirtualBox now adds VBoxServiceNT for NT4 guests (for time synchronization and guest properties). For the X11 host and guest clipboard, developers have fixed a number of issues, including some with seamless windows in X11 guests. Sun was also able to improve 3D support in VirtualBox by fixing dynamic linking on Solaris/OpenSolaris guests, and addressing issues with incorrect context/window tracking for multithreaded apps. fixed crashes when executing certain Linux guests (software virtualization only). fixed hangs and poor performance with Kaspersky Internet Security (VT-x/AMD-V only) fixed network regressions (guest hangs during network IO)
