Hi all,
We've got __HYPERVISOR_console_io working on our unikernel! The only
issue is that it prints to `xl dmesg`. Is there a way to get it to
print to `xl console`?
No. They are two very different consoles.
`xl dmesg` reads the hypervisor console, which is where
__HYPERVISOR_console_io hypercalls end up (in debug builds of Xen).
`xl console` however is the paravirtual console. Each domain has a page
of RAM (the PV console), which is mapped by the xenconsoled daemon in
dom0. xenconsoled performs duties such as logging and creation of a pty
master for two-way interaction. `xl console` connects to the pty master
for the appropriate domain.
To get messages appearing in `xl console`, you must implement the guest
side of the PV console interface.
