Re: [Xen-API] Wheezy xcp-xapi /usr/share/doc/xcp-xapi/README.Debian xe Error: Connection refused (calling connect )



Hi,

Having installed xcp on debian 6 recently (today), I can confirm that after installing xcp-xapi package does not disable xend (which is installed by the xen-hypervisor package).

3044 ? S 0:00 /usr/bin/python2.7 /usr/lib/xen-4.1/bin/xend start 3045 ? SLl 0:02 /usr/bin/python2.7 /usr/lib/xen-4.1/bin/xend start

This lead to a non fuctionnal xapi. You must stop the process and removing it from boot.

Maybe something that has to be fixed in next releases ?

Cheers,
Sébastien

no 'xapi' service means no 'xcp' at all. 90% of functionality provided by it. Try to /etc/init.d/xapi start (or xcp-xapi start).

I saw 'xend' log noted below. If this is not from older tests, you need to disable xend service to run xapi. Use command "update-rc.d xend remove" and try to start xapi again.

Thanks for the reply.  :-)  See console session, below.


I don't see a 'xapi' service.


I can't locate a 'xensource.log' file.


Rummaging around yesterday, I recall seeing a message to the effect that xe/xapi won't work when xend is running; but, I don't recall where.
