You will have to setup a serial console in order to debug then. You need to find the serial port of your box and hook a null modem [0] to it, and then plug the other side into another computer and use cu, minicom or some other program in order to get the serial output. There's a section on the handbook about how to use the serial console: https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/serialconsole-setup.html You will need to add something like: console=com1,vga com1=115200,8n1 to your xen_cmdline if you don't have it yet in order to get the output. > It seems related with Linux guests using kernel 4.x Does then same happen if you use a disk line like: 'format=raw, vdev=hda, access=rw, backendtype=qdisk, target=/dev/zvol/fbroot/SAND/disk' Note the 'backendtype' option is set to qdisk.
