Re: [Xen-devel] console problem

[Anthony Liguori <aliguori@xxxxxxxxxx>]

Yes, I'm aware of this.  The problem is that we've never had a good 
dependency system for the daemons we started.  The extra daemon has made 
the problem much worse and now we're seeing timing issues.
You can work around the problem by manually starting consoled (you may 
have to restart xenstored too).  Under the right circumstances, xend 
restart will loop because xenstored gets itself hosed.
I'm reworking a lot of this code right now to make it more robust and 
solve the problem completely.  Just hang in there a bit :-)

Anthony Liguori
