Make sure you have enough RAM (7168MB is fine), and eventually increase the number of vcpus.
Fetching and extracting the very release version that you are running,
mkdir -p /data/build/ cd /data/build/ ver=`uname -r` #ver=2.1 #ver=3.1.1 ftp -a ftp://ftp.ee.netbsd.org/pub/NetBSD/NetBSD-$ver/source/sets/syssrc.tgz #ftp -a ftp://ftp.netbsd.org/pub/NetBSD-archive/NetBSD-$ver/source/sets/syssrc.tgz #ftp -a ftp://ftp.fr.netbsd.org/pub/NetBSD/NetBSD-$ver/source/sets/syssrc.tgz #ftp -a ftp://ftp4.fr.netbsd.org/mirrors/ftp.netbsd.org/NetBSD-$ver/source/sets/syssrc.tgz progress -zf syssrc.tgz tar xf -
Handy symlinks,
ls -lhF /usr/src rm -f /usr/src ln -s ../data/build/usr/src /usr/src ls -lhF /root/src rm -f /root/src ln -s ../data/build/usr/src /root/src
Tweaking the kernel configuration,
#echo ${HOST%%\.*}
#kernel=`echo ${HOST%%\.*} | tr 'a-z' 'A-Z'`
#kernel=ALTQNPF
#kernel=INSTALLMULTI
#kernel=GENERICMULTI
#kernel=SMALLPLUS
cd /usr/src/sys/arch/`uname -m`/conf/
cp -pi GENERIC $kernel
#cp -pi XEN3_DOMU $kernel
#cp -pi INSTALL_SMALL $kernel
#cat >> $kernel <<-EOF
#nfe* at pci? dev ? function ? # NVIDIA nForce Ethernet
#EOF
vi $kernel
Eventually take the chance to disable INSECURE,
#options INSECURE
Make it Multiboot-compliant,
options MULTIBOOT
Enaling ALTQ,
#altq available options as for netbsd 8.0 options ALTQ # Manipulate network interfaces' output queues options ALTQ_BLUE # Stochastic Fair Blue options ALTQ_CBQ # Class-Based Queueing options ALTQ_CDNR # Diffserv Traffic Conditioner options ALTQ_FIFOQ # First-In First-Out Queue options ALTQ_FLOWVALVE # RED/flow-valve (red-penalty-box) options ALTQ_HFSC # Hierarchical Fair Service Curve options ALTQ_LOCALQ # Local queueing discipline options ALTQ_PRIQ # Priority Queueing options ALTQ_RED # Random Early Detection options ALTQ_RIO # RED with IN/OUT options ALTQ_WFQ # Weighted Fair Queueing
Enabling NPF,
pseudo-device npf # NPF packet filter options NPF_EXT_LOG options NPF_EXT_NORMALISE options BPFJIT options SLJIT
In case this is bare-metal and not a XEN nor serial console,
options WS_KERNEL_FG=WSCOL_BROWN #options WS_KERNEL_FG=WSCOL_RED
Note: there is no YELLOW.
grep WSCOL /usr/src/sys/dev/wscons/wsdisplayvar.h
Compiling the new kernel,
cp $kernel /data/build/ diff -bu GENERIC $kernel > /data/build/$kernel.diff #ls -alhF ../compile/$kernel/ #rm -rf ../compile/$kernel/ config $kernel dmesg | egrep ^[v]?cpu cd ../compile/$kernel/ time make -j16 depend > /data/build/$kernel.make.depend.log && echo SUCCESS tail /data/build/$kernel.make.depend.log #make clean time make -j16 > /data/build/$kernel.make.log && echo SUCCESS # 238.26s tail /data/build/$kernel.make.log
Bare-metal,
mv /netbsd /netbsd.old cp /usr/src/sys/arch/`uname -m`/compile/$kernel/netbsd / shutdown -r now
XEN host,
scp bsdbuild:/usr/src/sys/arch/amd64/compile/ALTQNPF/netbsd netbsd.altqnpf scp bsdbuild:/usr/src/sys/arch/amd64/compile/GENERICMULTI/netbsd netbsd.genericmulti
XEN guest,
shutdown -p now
and change its settings to point to the new kernel,
kernel = "/data/kernels/netbsd8/altqnpf"
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)
