I'm working on (re-) implementing serial console support in virtualbmc [1], and one of the issues I'm hitting right now is that after establishing a console connection via... self._stream = self._conn.newStream(libvirt.VIR_STREAM_NONBLOCK) self._domain.openConsole(None, self._stream, 0) ...I can't figure out how to close the console. Subsequent calls to openConsole fail because "a console connection is already open". I thought maybe I should close the stream, but that doesn't appear to be possible (there is a finish method, but it just t...

Hi! It's indeed better to open a new thread for this. So, here's my test session: $ qemu -fda extlinux.144 -s -S Then in another terminal: $ gdb extlinux.elf (gdb) set architecture i8086 (gdb) target remote localhost:1234 Remote debugging using localhost:1234 0x0000fff0 in ??

...se (from fp->oop->close) in the process of reloading ldlinux.c32, and while ansicon_counter is set to its initialised data value of 0 when reloading ldlinux.c32, the core is never reloaded, and so __file_info[] retains its pointers. What this amounts to is that when ldlinux.c32 tries to call openconsole() after being reloaded, the core tries to close the ansicon device (the core still has pointers to __ansicon_close) despite the ansicon code having no knowledge of ever being opened (because ansicon_counter was reinitialised). The most logical way to deal with this is to close stdin, stdout and s...

Hello all, We're having the following issue: when in UEFI mode, any output/errors from a lua script is invisible! This occurs even just running 'lua -v'. It runs and returns to a (visible) 'boot:' prompt, but there is simply no output visible from lua! (It does do a linefeed, but no visible text appears.) Has anyone encountered this? And/or know of a solution? For

Hi again. I was just wondering if there are any support for running programs inside a VM through libvirt. From what I can see in the API the only solution I found was connecting to the VM with openConsole and running the program I want. This however seems a bit tricky through Python and I was just wondering if there are any simpler solutions. Best regards.

...ole and I run "hdt", it displays the hdt screen on the VGA adaptor and not on the serial interface. In my pxeboot config file I have: serial 0 38400 console 0 prompt 1 I noticed that the main function in hdt.c has: console_ansi_raw(); /* Opening the Syslinux console */ // openconsole(&dev_stdcon_r, &dev_ansicon_w); Could the missing openconsole be stopping it from working on the serial console? Is there something I need to do to get hdt to run on the serial console? -- -- rouilj John Rouillard System Administrator Renesys Corporation 603-244-9084 (cell) 603-64...

From: Matt Fleming <matt.fleming at intel.com> The first two patches in this series are fixes for bugs reported by someone in #syslinux. The third makes dmitest.c32 actually wait for user input. If no one has any objections/concerns, I'll pull this into the official elflink branch. Matt Fleming (3): core: Print error message if we don't load ldlinux.c32 Clean up $(GPLLIB) leak

From: Matt Fleming <matt.fleming at linux.intel.com> This series fixes some bugs and switches the elflink branch to be entirely ELF modules. It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!). Now there should be no duplicate code because we don't need COM32 and

Hi all, I have released SYSLINUX 2.12-pre1. This version has an initial version of libcom32, a small C library based on klibc for writing com32 programs in C. It is far from perfect yet, but it should be a lot easier to use than hand-coding everything. As usual, find this stuff in: ftp://ftp.kernel.org/pub/linux/utils/boot/syslinux/Testing/ -hpa
