Re: [Xen-devel] Backend device in use after reboot

[Wensheng Wang <wenshengwang@xxxxxxxxx>]

I just looked at my /etc/init.d/xendomains, in stop(), it test a env
variable called XENDOMAINS_AUTO_ONLY, If it true, it shutdown only
those in /etc/xen/auto
And in my /etc/sysconfig/xendomains, this variable is indeed set false.

Then it try to "xm save" followed by "xm shutdown" if "xm save" failed.

In my /etc/sysocnfig/xendomains, XENDOMAINS_SAVE is set to
/var/lib/xen/save, But
I don't have this directory.  So it should proceed to shutting-down. 
It all look good to me.  I don't understand why I had this problem.
I will try reboot again and see what happens.  I only saw it once.
