Privileges, it's generally slower than bridged networking using a tap(4)ĭevice, and doesn't allow the use of diagnostic tools like ping(8) While QEMU user networking is easy to use and doesn't require root You can see NVMM's current status with nvmmctl(8): $ nvmmctl identifyģ0.3. Configuring bridged networking on a NetBSD host To create a dedicated user or group for them with useradd(8) On a machine containing lots of untrusted VMs, you may wish You probably want to run virtual machines as a non-root userįor security reasons, so set the owner of the /dev/nvmmĭevice to something reasonable: # chown nia:wheel /dev/nvmm However, since NVMM blocks things like suspend, you may wishīy default the /dev/nvmm device is owned by the Secmodel_securelevel(9) of 1, which prevents loading modules Loading NVMM at boot time will also allow the system to run with a You can load the module automatically at boot time by adding this Verify NVMM is loaded with modstat(8): # modstat | grep nvmm It must be activated by loading the nvmm module with The NetBSD Virtual Machine Monitor isn't active by default. In /stand are correct and up-to-date for the version The necessary features from the firmware at boot.īefore loading the NVMM module, make sure the modules Virtualization capabilities disabled by default.

Many computers (especially laptops) have hardware On NetBSD, this is supported with the virtio(4) drivers. You will generally want to use para-virtualized I/O, rather than having When running modern operating systems as VM guests, Other hypervisors supported by NetBSD include QEMU can also be used without an accelerator, with significantly reduced More backends for other architectures may be added in the future. NetBSD host run faster by taking advantage of CPU virtualizationĬurrently, a CPU that supports AMD SVM or Intel VMX is required, but In regular usage, it's used as an 'accelerator' for the QEMU Nvmm(4) (NetBSD Virtual Machine Monitor) is NetBSD's native
