I guess my report is not strict comprehensive, but it's useful and helpful for everyone who wants to use VirtualBox on FreeBSD. Tested environment: host os: FreeBSD 9-current amd64 (among 12/2009) virtualbox: virtualbox-3.0.51.r22902_3 cpu: Intel Core2 Quad Q9550 mem: 8GB video: GeForce 9800 GT Kernel settings: - Vimage lets FreeBSD freeze within VirtualBox bridge networking feature. VirtualBox settings: ------------------------------------------------------------- | | effects on the host os stability| ------------------------------------------------------------- | ACPI | NO | | IO APIC | NO | | PAE/NX | (not checked) | | Core numbers | YES (*1) | | VT-x/AMD-V | NO | | nested paging | (not checked) | | 3D acceleration | (not checked) | | IDE controller type | NO | | Additional controller | NO | | CD/DVD drive host | NO | | CD/DVD drive image file | NO | | FDD drive host | (not checked) | | FDD drive image file | (not checked) | | Audio | (not checked) | | Network adapter type | NO | | Network NAT | NO | | Network bridge | NO | | Network inner network | (not checked) | | Network host only | (not checked) | | Serial port | (not checked) | | share folder | (not checked) | | Guest OS sort | NO | ------------------------------------------------------------- (*1) Multicore attached virtual environment easily and frequently lets FreeBSD freeze. Hardware health: - Weakened PC power unit or less-power power unit leads PC very unstable condition. If you encounter non-reproducible error or panic, you should better to check your PC power unit. - Unstable memory leads FreeBSD system panic and fatal trap. If you encounter "segmentaion fault", "panic" or "fatal trap" error, shutdown system and check your PC memory health with memtest86+. (Ubuntu install CD has memtest86+ feature. Using Ubuntu as memetest86+ checker is reasonable way). If you have luck, updating BIOS and set DRAM settings for stable resolves this issue. - Hard Disk should be health. Check your disk status by smartmontools (sysutils/smartmontools). Driver: - NVIDIA driver (x11/nvidia-driver, nvidia-driver-195.22) leads FreeBSD freeze non-reproducibly. If you use both NVIDIA driver and VirtualBox along with non-reproducible FreeBSD freeze, use nv driver instead. Recap points: - Check your PC health first, especially for Power unit, memory and Hard disk. - Remove Vimage if you want to use bridge networking feature of VirtualBox. - Use nv driver instead of nvidia-driver if you have FreeBSD non-reproducible freeze problem with nvidia-driver. -- Daichi GOTO CEO | ONGS Inc. 81-42-316-7945 | daichi@ongs.co.jp | http://www.ongs.co.jp LinkedIn: http://linkedin.com/in/daichigoto
