This is a little dated but it means someone was taking a swing at this back with Karaf 3.x. I did see where Onos has moved on to using Karaf 4.x although I don't know if they are still using OSv. Being able to boot Karaf into unikernel means start up would be fast, there's little attack surface, and it won't have the overhead of VMs/Docker on top. Although I gather OSv could run in that environment as well as could other unikernels. Has anyone had any experience attempting to use Karaf with any unikernels good, bad or indifferent. I'm certainly for pursuing this farther but if it's already out there then there isn't any point in reinventing the wheel.
One complaint or problem with unikernels is there is only one allowed process running. You can't log into it as user. That's also part of its inherent security as well. That's why Karaf in that environment interests me so much as I don't need a user login to the operating system if I can log into Karaf itself. Unfortunately my knowledge is somewhat limited here that's why I though I'd ask if anyone had worked with it. Ideally I'd get a server with Xen running on it so I could compile this and test it. https://github.com/cloudius-systems/osv-apps/blob/master/onos/Capstanfile base: cloudius/osv-openjdk cmdline: > /java.so -Xms128M -Xmx512M -XX:+UnlockDiagnosticVMOptions -XX:+UnsyncloadClass -Dcom.sun.management.jmxremote -Djava.endorsed.dirs=/usr/lib/jvm/java/jre/lib/endorsed:/usr/lib/jvm/java/lib/endorsed:/onos/apache-karaf-3.0.3/lib/endorsed -Djava.ext.dirs=/usr/lib/jvm/java/jre/lib/ext:/usr/lib/jvm/java/lib/ext:/onos/apache-karaf-3.0.3/lib/ext -Dkaraf.instances=/onos/apache-karaf-3.0.3/instances -Dkaraf.home=/onos/apache-karaf-3.0.3 -Dkaraf.base=/onos/apache-karaf-3.0.3 -Dkaraf.data=/onos/apache-karaf-3.0.3/data -Dkaraf.etc=/onos/apache-karaf-3.0.3/etc -Djava.io.tmpdir=/onos/apache-karaf-3.0.3/data/tmp -Djava.util.logging.config.file=/onos/apache-karaf-3.0.3/etc/java.util.logging.properties -Dkaraf.startLocalConsole=true -Dkaraf.startRemoteShell=true -classpath /onos/apache-karaf-3.0.3/lib/karaf-jaas-boot.jar:/onos/apache-karaf-3.0.3/lib/karaf.jar:/onos/apache-karaf-3.0.3/lib/karaf-jmx-boot.jar:/onos/apache-karaf-3.0.3/lib/karaf-org.osgi.core.jar org.apache.karaf.main.Main build: make -- Sent from: http://karaf.922171.n3.nabble.com/Karaf-User-f930749.html
