You can use the "-h" option to bhyveload(8) to do this. For e.g., "bhyveload -h / vmx" will load the kernel from "/boot/kernel/kernel" and use the loader configuration from "/boot". > - how to pass the necessary config (rootpath) to the client > without having to rely on a specialized dhcp server > You can set environment variables using the "-e" option: bhyveload -e "boot.nfsroot.server=18.104.22.168" -e "boot.nfsroot.path=/exports/guest1" There are a number of other environment variables set by the PXE loader - see sys/boot/i386/libi386/pxe.c. I haven't done this myself therefore not sure if this would work. best Neel > I used to be familiar with diskless configs, so i can probably sort > out the server side myself. > > cheers > luigi _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
