problem with networking on Xen #124

Open bchalios opened 6 years ago

bchalios commented 6 years ago

I am trying to run the apache server from rumprun-packages.

I have built it and baked it according to the README but when trying to launch the unikernel on Xen I get the following error:

root@local:/home/bchalios/rumprun-packages/apache2# rumprun xen -i -I xen0,xenif -W xen0,inet,static,10.0.120.120/24 -b images/data.iso,/data bin/httpd_xen_pv.bin -k start -DONE_PROCESS

!!! !!! NOTE: rumprun is experimental. syntax may change in the future !!!

This seems to be caused by you not having your xen bridge device enabled, your /etc/network/interfaces file should look something like this for xen guests to have networking enabled

iface eth0 inet manual

iface xenbr0 inet dhcp
    bridge_ports eth0
