grab-binary | grab-source | kernel | cross | world | tweaks
assuming same NetBSD release or at least branch – no need to build tools
make sure you have enough RAM (at least 2GB I would say, but 8GB is probably preferable), and eventually increase the number of vcpus
first see netbsd-tweaks then proceed with building
you don’t have to download all the sources, but that works only on same release
MAKEFLAGS -->config $kernel #/usr/tooldir/bin/nbconfig $kernel dmesg | grep -E [v]?cpu echo $MAKEFLAGS cd ../compile/$kernel/ time make depend > make.depend.log && echo READY #/usr/tooldir/bin/nbmake
#make clean time make > make.log && echo BUILT #/usr/tooldir/bin/nbmake
–either– deploy locally (bare-metal or KVM guest)
mv -f /netbsd /netbsd.old #cp /usr/src/sys/arch/`uname -m`/compile/$kernel/netbsd / cp -i netbsd / shutdown -r now
–or– keep a remote copy of it (e.g. for a XEN host)
guest=netbsd-lbs conf=PFCOM1 kernel=netbsd100.pfcom1 ssh -tn $guest ls -lhF /usr/src/sys/arch/amd64/compile/$conf/netbsd scp $guest:/usr/src/sys/arch/amd64/compile/$conf/netbsd $kernel chmod -x $kernel
apply the change to the XEN guest – change its settings to point to the new kernel
shutdown -p now
kernel = "/data/kernels/netbsd100.pf"
at system startup, watch the console and check
dmesg | grep ^NetBSD uname -a
make[1]: don't know how to make absvdi2.c. Stop
==> either use config -s
or put your sources folder in the default location (/usr/src
)
while trying to run PFALTQ (based on GENERIC) as PVH guest
xc: error: panic: xg_dom_hvmloader.c:110: xc_dom_parse_hvm_kernel: ELF image is not 32bit: Invalid kernel
==> PVH support is in current, not 9.3 just yet
