All, I'd like to be able to launch at least 25 UMLs, preferrably at boot time, and have the option to connect when needed a serial console for out of band management. So the problem is twofold: 1) How to launch a bunch of UMLs. At boot as a last SysV action ? 2a) How to launch UMLs with the possibility of offering a serial line that can service console prompt 2b) How to eventually and sometimes connect to these serial lines. For a serial utility I'm looking at conserver: http://www.adamsinfoserv.com/twiki/bin/view.cgi/HLUG/UsingConserverWithUserModeLinux Anyone using that ? What are you using ? To launch them I'd like to eventually wrap their launch in Perl, along with other stuff, but for now I'm considering simply something like: /path/linux ubda=mycow1,fs-1 umid=uml1 eth1=daemon,/tmp/switch1 & /path/linux ubda=mycow2,fs-2 umid=uml2 eth1=daemon,/tmp/switch1 & /path/linux ubda=mycow3,fs-3 umid=uml3 eth1=daemon,/tmp/switch1 & /path/linux ubda=mycow4,fs-4 umid=uml4 eth1=daemon,/tmp/switch1 & But then I've noticed and read that a UML might not fully boot if there's no console. Also, in which way the file system's inittab influences the use of serila console access from the host ? Does the file system inittab's tty declarations have any influence in that ? Thanks for any suggestions/hints/comments. |

Hi lanas I boot up normally in an xterm console and I have put an inittab which includes ttyS0::respawn:/sbin/getty -L ttyS0 9600 vt100 tty0::respawn:/sbin/mingetty --noclear tty0 and it also uses a serial console from the host once it bootup up. So after bootup I know which /dev/pts is using as the xterm windown show which host serial console it is attached. So I use SCREEN program to attach/deattach to the UML, also you can capture with one session multiple consoles and leave them running in the background and it works just fine. Sorry I can't help you more.

Forgive the glib answer but, are you sure you don't just need to "apt-get install gcc" (or yum or rpm or whatever you install packages with)? --David. ________________________________ From: Jawad hussain [mailto:jaw...@gm...] Sent: Friday, February 27, 2009 5:23 PM To: David Francisco Rodriguez Perez Cc: Use...@li...
