Dear all I have been trying to setup stubdomains for added security on a test machine so I could then suggest to use xen at work with some added "backbone" and practical experience.
Unfortunately I am unable to launch domains with a stubdomain when there's a NIC configured in the VM config file. The Domain launches without problems when I comment the vif= entry. The Error I am getting is the following: libxl: error: libxl_dm.c:1284:stubdom_pvqemu_cb: error connecting nics devices: No such file or directory I have tried different types as well (ioemu, etc.). More logs/configs can be found further below.
