Re: [Xen-users] cross hypervisor communication problem
Andy,
I talked to the networking guys, they had that feature enabled.
Unfortunately disabling it didn't help.
However, I did stumble upon something interesting.
route showed something like this
localnet * 255.255.255.0 U 0 0 0 eth0
default something 0.0.0.0 UG 100 0 0 eth0
getting rid of the route for localnet and sending everything to the
default gateway fixed everything. Unfortunately, I consider this more
of a temporary hack then a solution. Does anyone see something I am
missing, or perhaps a better solution?
Andy - thanks for all the help btw.
Thanks,
