Ian Pratt wrote: The attached patch removes all of the console handling code from Xend and changes xm to simply exec /usr/libexec/xen/xc_console.Please can you provide some more detail, particularly how it changes things from a user point of view. How do you disconnect and reconnect to consoles? Does the '-c' option to xm still work? Can the user control allocation of are tty names? xm console still connects and disconnects to the console. xm create -c still works as expected.You still disconnect from the console with C-]. The only user facing difference is that xm list does not have a console field (the port it showed previously was meaningless anyway with domain sockets) and xm no longer supports the consoles command (since again, the information it was displaying wasn't all that useful). If we export over tcp then we can add some info back into xm. However, I'd much rather implement the NSS plugin we talked about at the Summit. tty names are automatically chosen by the OS so there isn't really anything to control. I put it there since that's where we have xenstored installed. We can certainly install it somewhere else though.Also, should consoled really line in /usr/sbin/ ? I think it should be in /usr/lib/xen/bin (Didn't we decide /usr/libexec was deprecated anyhow?) If it is, I'll submit a patch to relocate the contents of /usr/libexec/xen. I've not been able to reproduce it. I had 50 domains running all cat'ing /dev/urandom and I was able to input/output large amounts of data without corruption to another domain.BTW: does this fix the console output corruption bug that's on the books? With that said though, I'm still not convinced it's fixed completely because I don't think xcs buffers everything correctly. The new console drivers should do the trick though since we won't need to go through xcs. Regards, Anthony Liguori Thanks,IanI've done a pretty good amount of testing and this seems to clear up all of the Xend console issues in bugzilla.This is a pretty big change to Xend though with a lot of deleted code so I'd appreciate if people more familiar with the Xend codebase could look through it critically.In addition to the patch, the following files are no longer used: tools/python/xen/util/console_client.py tools/python/xen/xend/XendConsole.py tools/python/xen/xend/server/SrvConsole.py tools/python/xen/xend/server/SrvConsoleDir.py tools/python/xen/xend/server/console.py Regards, Anthony Liguori Signed-off-by: Anthony Liguori <aliguori@xxxxxxxxxx> _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
