Preview of Next Generation VM-Tools

Preview of Next Generation VM-Tools

[Anthony Liguori]

Hi all,

I've posted a preview release of the next generation of VM-Tools.  This 
generation of the tool chain will be different from the existing 
versions of VM-Tools in a number of important ways.  Below are the 
highlights:

o Single daemon based system
o Support for 3.0 and 2.0.x trees
o Improved logging via syslog
o Many others

This is just a preview release and is not meant to be used for anything 
other than simply understanding the new architecture.  The README in the 
tarball includes a list of what's working and what's not working.

We anticipate a full release within the new few weeks.

hi Anthony,

there seems to be a race in the creation of new domains, if I run the 
commands from the README in a script, xenctld prints:

xenctld: New domain-0
xenctld: Binding to port 0:0
xenctld: Got message destined 1:0:1
xenctld: Received msg for unknown domain-1
xenctld: New domain-1
xenctld: evtchn_bind_interdomain(32752,1,0,1) failed: Invalid argument
xenctld: Failed opening event channel

Whereas If I put a 'sleep 1' between each of the lines in the script, 
the domain starts up and connects the conosole without problems.

I noticed that myself.  Xencltd uses a timeout to update it's 
information about domains.  What it needs to do is make sure that any 
entry into xenctld causes the information to be updated.

That's for pointing it out.  It'll be fixed for the next release.

Great, looking forward to that. Also, there seems to be a problem with 
newlines in the console, hitting <ENTER> a few times yields:

~ #
     ~ #
         ~ #
             ~ #

Perhaps carriage-returns are not handled correctly?

Anthony, looks like you forgot the Makefile target (compile and clean)
of bindings/ ?
