[Pkg-xen-devel] Bug#680528: xcp-xapi: /etc/init.d/xendomains cause xapi to hand during boot

Package: xcp-xapi
Version: 1.3.2-8
Severity: important
During startup /etc/init.d/xendomains script is called. That script is installed
with xen-utils-common witch xcp-xapi is depends on.
That script calls /usr/sbin/xen
as
xen list &> /dev/null
This 'xen' seems to call xapi:
xen list
^Z
[1]+ Stopped xen list
root at lab-xh3:~# ps f
PID TTY STAT TIME COMMAND
3940 pts/6 Ss 0:00 -bash
3982 pts/6 T 0:00 \_ /usr/sbin/xapi list
That call is never ends.
I think this is not desired behavior:
1) Script xendomains is provided by xen-utils-common
2) /usr/sbin/xen is provided by xen-utils-common
3) 'list' seems be addressed to xm/xl toolstack (not sure)
4) TOOLSTACK is pointing to xapi.
5) XAPI is not ready to serve 'list' domains and start like it expect to be 'initialized', not queried.
6) Boot process do not finish.
I think disabling of xendomains should be noted in README.Debian, or, better, checked during installation.
Future, it can be fix to xendomains script to exit if toolstack is xapi.
Not sure is should be reported to xen package as well.
PS Everyone, who affects this problem:
update-rc.d xendomains remove
