Migrating physical Trixbox 2.0/Asterisk => VE: no network [message #9790]

Trying to migrate physical server Trixbox 2.0/Asterisk to VE. What I did was create a Cantos VE and from inside there I rsync'ed a physical Trixbox server. I then copied the /etc/sysconfig/network-scripts directory from a working VE. But the networking isn't working and from inside the VE I get this when restarting the network.

service network restart
Shutting down interface venet0: [ OK ]
Shutting down loopback interface: [ OK ]
Setting network parameters: error: unknown error 1 setting key 'kernel.sysrq'
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
error: unknown error 1 setting key 'kernel.core_uses_pid'
error: unknown error 1 setting key 'net.ipv4.tcp_syncookies'
[FAILED]
Bringing up loopback interface: [ OK ]
Bringing up interface venet0: [ OK ]

What am I missing? Thanks in advance.

Please, we need the output of the following commands:
1) `ip a l` in VE
2) `ip r l` in VE
3) `iptables-save` in VE
4)-6) above commands on the host itself
7) `sysctl net.ipv4.ip_forward` on the host

And please, specify kernel version you use.

Looks like correct configuration. Could it be DNS issue?

Definitely not a DNS issue. I can't see why DNS would make this error.

Above messages are because in VE context change of this sysctls is prohibited. Could you ping host node by its IP from VE? Could you ping external IPs from VE? Could you ping VE from host node?

Thanks for your help.

Remember I started this by copying a physical machine into a VE. So I suspect that the problem is related to network scripts. What I need to do, which I thought I did was to merge the networking from a VE and physical copy.

I copied the /etc/sysconfig/network-scripts directory. Are there other directories and files I need to copy?

New details.

Migght not be VE related. On the HE I can't seem to add additional IP addresses there either. The main IP works but only the main IP.

Looks normal to me but the IP address 69.50.231.9 is dead. I'm not sure what's wrong but sure could use some help. How do you troubleshoot this?
