15 Change log 15.22 Version 3.0.0 (2009-06-30) This version is a major update. The following major new features were added: • Guest SMP with up to 32 virtual CPUs (VT-x and AMD-V only see chapter 3.4.2, “Processor” tab, page 44) • Windows guests: ability to use Direct3D 8/9 applications / games (experimental see chap- ter 4.4.1, Hardware 3D acceleration (OpenGL and Direct3D 8/9), page 64) • Support for OpenGL 2.0 for Windows, Linux and Solaris guests In addition, the following items were fixed and/or added: • Solaris hosts: allow suspend/resume on the host when a VM is running (bug #3826) • Solaris hosts: loosen the restriction for contiguous physical memory under certain condi- tions • Mac OS X hosts: fixed guest PAE • Linux hosts: kernel module compile fixes for 2.6.31 (bug #4264) • VMM: fixed occasional guru meditation when loading a saved state (VT-x only) • VMM: eliminated IO-APIC overhead with 32 bits guests (VT-x only, some Intel CPUs don’t support this feature (most do) bug #638) • VMM: fixed 64 bits CentOS guest hangs during early boot (AMD-V only bug #3927) • VMM: performance improvements for certain PAE guests (e.g. Linux 2.6.29+ kernels) • VMM: some Windows guests detected a completely wrong CPU frequency (bug #2227) • VMM: fixed hanging and unkillable VM processes (bug #4040) • VMM: fixed random infrequent guest crashes due XMM state corruption (Win64 hosts only) • VMM: performance improvements for network I/O (VT-x/AMD-V only) • GUI: added mini toolbar for fullscreen and seamless mode (Thanks to Huihong Luo) • GUI: redesigned settings dialogs • GUI: allow to create/remove more than one host-only network adapters (non Windows hosts) • GUI: display estimated time for long running operations (e.g. OVF import/export) • GUI: fixed rare hangs when open the OVF import/export wizards (bug #4157) • 3D support: fixed VM crashes for client applications using incorrect OpenGL states • 3D support: fixed memory corruption when querying for supported texture compression formats • 3D support: fixed incorrect rendering of glDrawRangeElements • 3D support: fixed memory leak when using VBOs • 3D support: fixed glew library detection • 3D support: fixed random textures corruption 215
