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

[Sébastien Riccio <sr@xxxxxxxxxxxxxxx>]

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
