Yes, it would be very good to remove that, as it usually tries to grep a non-existent file /var/run/dmesg.boot that is not created until after vm_bhyve has been called from /usr/local/etc/rc.d when you have things set to autostartup in /etc/rc.conf > > I notice that the following 2 sysctl's appear to be set to 1 as soon as the > vmm module is loaded > > hw.vmm.vmx.initialized: 1 > hw.vmm.vmx.cap.unrestricted_guest: 1 > > Will these be available on both Intel & AMD processors as a way to determine > if the module has loaded successfully and can run guests? > > I also see the below sysctl related to iommu. > > hw.vmm.iommu.initialized > > Again, will this be set to 1 as soon as the module is loaded if iommu is > supported, or only when it is used? > There also seems to be a vmm.amdvi.enable sysctl.

Probalby the safest way for a shell script to decide if bhyve is up and running is to stat /dev/vmm, if that exists then the modules have loaded and initialized and bhyve should be ready to process guests. sysctl's mentiond above would be a poor way to make this determination. -- Rod Grimes [email protected] _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "[email protected]"
