Xen Hypervisor - VM not visible to outside machines

Xen Hypervisor - VM not visible to outside machines

[-- Attachment #1.1: Type: text/plain, Size: 422 bytes --]

Hi,

I have installed the Xen 4.1 Hypervisor on Ubuntu 11.10. I have a single VM
on the Xen that runs Ubuntu 10.10.
I am able to connect to the network and ping from the VM to the host
machine as well as to outside machines.
But the outside machines are not able to ping the VM since the VM is not
visible on the network.

Is there any way I can resolve this? If so, could you please suggest the
procedure to be followed?

This is likely to be a configuration issue and therefore would be more
appropriate for xen-users@ in the first instance. The xen-devel@ list
focusses on discussion of the development of Xen
http://wiki.xen.org/wiki/Asking_Xen_Devel_Questions. I have moved this
post to xen-users@ and put xen-devel@ to bcc.

If I were you I would start by checking my firewall configuration in
both dom0 and domU.

If this doesn't help then I suggest you include more details about the
specifics of your configuration, at a minimum all the networking related
stuff mentioned on http://wiki.xen.org/wiki/Reporting_Bugs_against_Xen,
precise kernel versions for dom0 and domU, exact guest configuration and
whatever else you feel might be relevant.

Thanks,
Ian.
