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`?

Hi all,
I'm writing some development tools for my team. Given a domain ID,
is there a way to programmatically check whether gdbsx is running on
that domain and what port it's running on? I could use something
like `top -b -n 1 | grep gdbsx` but that seems very brittle.

the input registers?
Is it because the registers are callee-saved? If that's the case,
why not just put them in the clobber list?

Hi folks,
On page 12 of "The Definitive Guide to the Xen Hypervisor", it is mentioned
that "Xen, like Linux, uses the MS-DOS calling convention, rather than the
UNIX convention used by FreeBSD."
I keep digging online and I can't find any information about an "MS-DOS
calling convention". We've
? Or is it done implicitly somehow?

just do HYPERVISOR_console_io hypercalls.
What strategy would you use to debug this early in the development
process? Is there a debugger I should be using?
I'd appreciate any information and any links to information, even
when it's only tangentially relevant.
Thanks in advance,

* After all of this is done, how can I verify that my compiled
binary indeed has a valid PT_NOTE entry for Xen? Does `readelf` have
a switch that's particularly appropriate for this?
