It was attaching the consoles to a host portal which another UML was already using. I got semi-reasonable "that portal is already in use" errors in between the parse_chan_pair things. So, were you trying to reuse some host devices, and which ones? An improvement in the errors might be in order here.

An > improvement in the errors might be in order here. I don't know. The did my standard "rootfstype=hostfs rw init=/bin/sh" thing, which should only have on process (a shell) on /dev/console. All that happened before that even managed to run /bin/sh. I don't think I had any other type of console support even built into the thing. (Console on stderr support, everything else disabled.) No idea what devices it was talking about... > Jeff Rob -- Never bet against the cheap plastic solution. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
