Re: [9fans] plan9 on qemu and 9vx
It seems that 9vx has become a lot more stable than before. The last time I used it to write anything in C was like 8 months ago, and the instability issues I had in mind are dated from back then. So I'll give it another try and perhaps it will become my main plan 9 platform. 2010/3/13 ron minnich : > I build 9vx from source and routinely have it running for days, until > I need an ubongo reboot in fact.

Re: [9fans] plan9 on qemu and 9vx
I build 9vx from source and routinely have it running for days, until I need an ubongo reboot in fact. Don't know how to figure out what's different but I do know that gcc/glibc/distros in linux universe are so variable, literally week to week, that the build environment is very unstable. That might be an issue with any prebuilt version, or a version you build yourself -- you really can't win. ron

In fact I did a "curried pipe" in > 9vx just to try some things out. i find development to go very fast on plan 9. now that /dev/reboot $kern is working for me, i can restart the kernel in less time than it takes the monitor to reset. (0.5s) of course kenc is faster than gcc. the added benefits are that i can debug device drivers and use regular kenc style or gcc's different % rounding and the little differences between 9vx and the regular kernel. i've found it very comfortable for building some rather large systems. - erik
Re: [9fans] plan9 on qemu and 9vx
9vx crashes on me quite often, and qemu doesn't. That's the only reason I use qemu, otherwise I'd also be stuck with 9vx too :-) Are you running the latest from sources, or are you using the prebuilt binary? There are important stability fixes in the sources that aren't in the binary (unless its been updated recently). Hugo Tim Newsham | www.thenewsh.com/~newsham | thenewsh.blogspot.com

Re: [9fans] plan9 on qemu and 9vx
Unless there's some compelling reason to use qemu (I can't think of one) why not just use 9vx exclusively? I've made a transition over the years: qemu xen kvm lguest 9vx And am stuck at 9vx ... ron

2010/3/12 hugo rivera : > But the next step I want to take is to run just a terminal with qemu, Since it looks like you have the option, I would not suggest to use a qemu image as your terminal. Instead, make 9vx or drawterm your terminal and you will have access to your host file system for free (and to the clipboard!). I have not used qemu images extensively, but the few times I have, I found much better to use drawterm or cpu into it from 9vx than running rio inside qemu. -- - yiyus || JGL . 4l77.com

Saludos a todos, I use u9fs and run it on my Linux / BSD machines using tcpserver (though inetd works too) I run them with -a none :) but it's a private LAN. Auth does work but I don't use it. You can also run u9fs on the end of ssh, e.g. tcpserver localhost 564 ssh remote u9fs -a none see http://man.cat-v.org/plan_9/4/u9fs for more details
