[Xen-users] start postgres server problem on domU

["Yikuo Chan" <yikuo.chan@xxxxxxxxx>]

Dear all :

I got below error message when I try to running postgres server on domU , is anyone have 
experience about  runing postgres on domU ?

[postgres@vm1 postgres]$ /usr/bin/postmaster -D /var/lib/pgsql/data
LOG:  could not bind IPv4 socket: Cannot assign requested address
HINT:  Is another postmaster already running on port 5432? If not, wait a few seconds and retry.
WARNING:  could not create listen socket for "localhost"
FATAL:  could not create any TCP/IP sockets
[postgres@vm1 postgres]$


here is my xen server information and domU's configure
xen server

# Configure the behaviour when a domain exits.  There are three 'reasons'
# for a domain to stop: poweroff, reboot, and crash.  For each of these you
# may specify:
#
#   "destroy",        meaning that the domain is cleaned up as normal;
#   "restart",        meaning that a new domain is started in place of the old
#                     one;
#   "preserve",       meaning that no clean-up is done until the domain is
#                     manually destroyed (using xm destroy, for example); or
#   "rename-restart", meaning that the old domain is not cleaned up, but is
#                     renamed and a new domain started in its place.
#
# The default is
#
#   
#   on_reboot   = 'restart'
