Well, that exactly I'm talking about. If you after start will looks ps aux|grep xapi, you will see 'hanged' xapi.

Anyway, I'll dig in in near time to see what happens inside.

I've glad to hear it not my personal bug or mistake.

My plan to test:

1) Disable all xcp/xen based services from boot.
2) reboot and try to bring it manually
3) If found buggy behavior - get minimal condition to reproduce
4) If not - add logging strings to every script to get boot sequence
5) repeat it manually

/etc/rc.local doesn't work (as stated in my previous post).
After reboot, when I do:

service xcp-squeezed status

I always obtain failed (I must do service xcp-squeezed start, and the daemon starts without problem).

The same is when I put this instruction into my own separate script, which I start-depend on all xcp daemons (xcp-xapi, xcp-squeezed, xcp-v6d xcp-fe). Whenever xenstore-write appear in boot scripts, the xcp-squeezed fails to start (or maybe this is issue with status printing?).

Well, 1st problem I do have around this is xcp is not starting properly
any way at system boot. I've still in research about reason and
solution, but for this exact case I think simplest solution is put this
line or in the /etc/init.d/xcp-xapi, or in /etc/rc.local.

But xcp-xapi start problems (which one is kinda hard to debug due
dependency based boot sequence) is more serious, I think.

Try this workaround: log into your debian dom0 and type:

$ sudo xenstore-write /local/domain/0/vm hello

When xapi adds a device it performs a sanity-check [...]


how I can "automatize" this workaround, so it works after reboot?
I've tried to put these instructions into init.d/* script and also
into rc.local but it prevents somehow xcp-squeezed from starting
