Any ideas why the default gateway disappears on reboot? Should I try
reinstalling Xen?
Any help at all is really appreciated.

Hello all,
I tried to install Xen on my CentOS server, and everything seems to go
right, but once I reboot, there is no default gateway for my network
connections, so I cannot connect in or out. That is all on dom0.
I spent about two hours in the centos channel to get this sorted out,
and all the scripts seem to be okay.
Note that the last line from netstat -rn was manually added via KVM by
me, so it doesn't appear when the system is rebooted.
Here is the output for netstat -rn ; ifconfig eth0 ; ifconfig eth1 ;
cat /etc/sysconfig/network ; cat
/etc/sysconfig/network-scripts/ifcfg-eth0 ; cat
/etc/sysconfig/network-scripts/ifcfg-eth1
[root@dhcp-123 xen]# netstat -rn ; ifconfig eth0 ; ifconfig eth1 ; cat
/etc/sysconfig/network ; cat /etc/sysconfig/network-scripts/ifcfg-eth0
; cat /etc/sysconfig/network-scripts/ifcfg-eth1
