VMWare Host intermittetly showing "no route to host" on the internal vmnet8 server address
You have incorrect (default) gateway 10.101.204.1 for subnet 192.168.238.0 on mithril. It is possible reason for problem. Try to add correct (192.168.238.1):
route add -net 192.168.238.0 netmask 255.255.255.0 gw 192.168.238.1
or
route add -net 192.168.238.0 netmask 255.255.255.0 gw 192.168.238.1 dev vmnet8
Also recheck default gateway on host mashine with netstat -rn

I am running NAT on an ubuntu host machine to linux guests. The vmnet8 address is getting Destination Host Unreachable when pinging from the host machine itself.

I am seeing intermittent "host unreachable" errors on the host just pinging the VMNET8 interface.
steve@hostmachine:/shared$ ping 192.168.238.130 PING 192.168.238.130 (192.168.238.130) 56(84) bytes of data.

Why would this happen? Any suggestions on how to fix this?
@september: (In response to inquiry): presently the error is not showing up (thus the 'intermittent' qualifier to this issue). But in any case here is output of netstat -rn
