Ping Failed when creating new XEN machines

When ever i create a Xen instance i get the completed successfully notification apart from the error below and ping always fails to the vm.

“xen instance was started, but could not be accessed via SSH after 60 seconds”

i can access the machine only via the console and not via ssh or web (locally or externally)

It seems it is something in my configs as the machine is obviously running ok and i can connect via console.

I realy don’t know where to start looking for config files via cloudmin gpl.

If i do a ifconfig in the console then i get the requested IP i assigned but i cannot ping the gateway (the host machine or web addresses).

This is the part of the boot log i think is relevent to networking.

netfront: Initialising virtual ethernet driver.
netfront: device eth0 has flipping receive path.

any advice appreciated.

This is the output from the console when booting.

All sorted now thanks.

I’m having the exact same issue. What did you do to take care of the problem? Thanks.

It apprears you did not get an answer when you had that issue.
I happen to be in the same position as you back then.
How did you solve it?

How did you solve it?
I have the same problem!

Thank you

Has anyone ever found out what the solution to this was, as I am having the exact same issue (except with KVM, not XEN VMs).
