i enabled source based routing in sysctl.conf with:-

net.ipv4.conf.default.accept_source_route = 1
net.ipv4.conf.all.accept_source_route = 1

then restarted the network on the HN:-

[root@xxx~]# service network restart
Shutting down interface eth0: [ OK ]
Shutting down interface venet0: [ OK ]
Shutting down loopback interface: [ OK ]
Disabling IPv4 packet forwarding: [ OK ]
Setting network parameters: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]
Bringing up interface venet0: [ OK ]

everything ok, but then in the VE:-

[root@vps101 /]# service network restart
Shutting down interface venet0: [ OK ]
Shutting down loopback interface: [ OK ]
Setting network parameters: 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.sysrq'
error: unknown error 1 setting key 'kernel.core_uses_pid'
[FAILED]
Bringing up loopback interface: [ OK ]
Bringing up interface venet0: [ OK ]

then from HN:-

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
85.17.*the VE IP* 0.0.0.0 255.255.255.255 UH 0 0 0 venet0
85.17.*the HN IP* 0.0.0.0 255.255.255.192 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 85.17.182.254 0.0.0.0 UG 0 0 0 eth0

and from ve:-

[root@vps101 /]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.0.2.0 0.0.0.0 255.255.255.0 U 0 0 0 venet0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 venet0
0.0.0.0 192.0.2.1 0.0.0.0 UG 0 0 0 venet0

any ideas?
