Cannot ping xen guests from external computer
I installed centos 5 x86_64 with xen in order to create multiple guests. The install of both the host and first guest went smoothly. The first guest is running Fedora 8 x86 as a fully virtualized guest (not paravirtualized).
I can access the internet from the guest and can successfully ping from the host to the guest and from the guest to the host. I can also ping from another computer running on the network to the host. I cannot, however, ping from another computer to the guest.
I have tried a crossover cable to rule out gateway/firewall issues but get the same results. I have also tried googling this issue but could find nothing that directly addresses this issue.
How can I ping my xen guests from another computer on the network?
