You didn't actually mention at what point it doesn't work, so here's my
best guess.
Sorry. I can't ping from domU to dom0.

It seems to me that your virtual network interface (vm01) and external/real
network interface (eth0) are on the same subnet (and even have the same
address). This doesn't make sense to me and I don't see how routing can work
like this. Aside from that, if it were to work, your gateway inside domU
should probably be 192.168.1.250
or else domU will not be sending outgoing
packets to dom0.
I tried to set the gateway inside domU to 192.168.1.250 and still it doesn't work.
As for the same ip address for both interfaces, i was confused myself until i saw a post on the mailing list which mentioned that using the route method copies the ip of the eth0 to the vif<id>.0 . Same was posted in the wiki as well ->
http://wiki.xensource.com/xenwiki/XenNetworking
P.S. I see my config for the domU has "192.168.1.1" as gateway, i will change that and post results.
