Compilation was done on some enterprise-class IBM servers dating 2007 with 4x4 Xeon processors and 96 GB to 128 GB of RAM. For 16 cores in total and with 1 thread per core (lscpu), I obtained the fastest results with -j16 for xen versus -j24 for tools and stubdom. Anyway, tune the number of make jobs according to your hardware.

eventually setup slackpkg+ against slackonly
ls -lF /var/log/packages/yajl* slackpkg install yajl-2
or fetch and build it yourself

note. if you want current,
#git clone git://xenbits.xen.org/xen.git
compile,
#rm -rf xen-$ver/ tar xzf xen-$ver.tar.gz cd /data/kernels/xen/xen-$ver/ #make clean-xen >/dev/null && echo CLEANED time nice make -j$j xen > ../make.xen.$HOSTNAME.log && echo BUILT #1m0.191s time nice make install-xen > ../make.install-xen.$HOSTNAME.log && echo INSTALLED ll /xen* /boot/xen* ln -s boot/xen.gz /xen.gz cd ../
installing the latest ACPICA (20180427 fails), for the xen tools to compile,
#Intel license #wget https://acpica.org/sites/acpica/files/acpica-unix-20190816.tar.gz #GPL wget https://acpica.org/sites/acpica/files/acpica-unix2-20190816.tar.gz tar xzf ... cd ... nice make -j$j > ../make.acpica.$HOSTNAME.log && echo BUILT make install > ../make.acpicainstall.$HOSTNAME.log && echo INSTALLED cd ../
installing the corresponding multilib version of gcc and glibc (and installing compat32-tools),
mkdir /data/kernels/xen/tftpboot/compat142/ cd /data/kernels/xen/compat142/ lftp -c 'open http://slackware.com/~alien/multilib/ ; mirror -c -e 14.2' #lftp -c 'open http://slackware.com/~alien/multilib/ ; mget -c 14.2/*' du -sh 14.2/ #343M cd /data/kernels/xen/compat142/14.2/ #upgradepkg --reinstall --install-new *.t?z upgradepkg --reinstall --install-new gcc-5.5.0_multilib-x86_64-1alien.txz upgradepkg --reinstall --install-new glibc-2.23_multilib-x86_64-4alien.txz upgradepkg --reinstall --install-new compat32-tools-3.8-noarch-6alien.tgz #upgradepkg --reinstall --install-new glibc-solibs-2.23_multilib-x86_64-4alien.txz ls -lF /var/log/packages/compat32-tools* ls -lF /var/log/packages/glibc* ls -lF /var/log/packages/gcc* cd ../../
Fetch ipxe & seabios GIT repos through https://

and this will be useful for other pieces of software, since you’ve got compat32
vi /etc/profile export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
without autoballoon nor anything specific
mv -i /etc/xen/xl.conf /etc/xen/xl.conf.dist egrep -v '^[[:space:]]*(#|$)' /etc/xen/xl.conf.dist #empty vi /etc/xen/xl.conf #https://xenbits.xen.org/docs/unstable/man/xl.conf.5.html #autoballoon="on" #vif.default.script="vif-openvswitch"
now we want to enable the XEN daemons at boot time alright.
ls -lF /etc/rc.d/init.d/xen* vi /etc/rc.d/rc.local
the default scheduler is now Credit2, since 4.10 or 4.12
/usr/local/sbin/xl sched-credit2 --domain=0 --weight=512 /usr/local/sbin/xl sched-credit2
we keep using xendomains because otherwise, guests live alone while dom0 shuts down.
#self verbose /etc/rc.d/init.d/xencommons start /etc/rc.d/init.d/xendomains start
and shutdown
vi /etc/rc.d/rc.local_shutdown #!/bin/sh #self verbose /etc/rc.d/init.d/xendomains stop /etc/rc.d/init.d/xencommons stop chmod +x /etc/rc.d/rc.local_shutdown grep rc.local_shutdown /etc/rc.d/rc.*

Choose either GRUB2 or SYSLINUX – LILO is not an option here (unless you want to play with mbootpack)
