definitely some issue with your setup because the
fact 'Host can't ping any VServer' is equal with
'host can't ping it's own ip addresses'

while the first statement leaves a lot of options
(iptables, network config, etc ...) this reduces
the range to a few, with one very likely candidate
most likely your lo device is misconfigured
make sure that:
- lo is up (UP LOOPBACK RUNNING)
- lo is configured with 127.0.0.1/8

in any case, make sure that you define the IP
of the vserver as 'localhost' in etc hosts, this
will make sure that the packets are redirected
