Re: [MirageOS-devel] Routing.No_route_to_destination_address running Mirage web server
Hi,
I have a similar problem, please find the code (a revised http-fetch
version) in the following repo:
https://github.com/lcoviedo/mirage-http-fetch
The unikernel only works fine when runs as a unix backend using
socket network stack, otherwise I get the errors below (DHCP full
process is run twice, and crashes after ARP timeout).
Interestingly, packet capture on eth0 shows the gw replying to arp
requests. Also, removing ctx from HTTP.get that makes use of default
resolver builds and runs but results in "name resolution failed
unknown endpoint type", however the arp timeout and twice-dhcp
process problems do not persist.
Help is much appreciated.

Hello
I am trying to run a static Mirage web server on a local Xen server.
When I do
curl 192.168.1.111
from dom0 it works fine.
When I try to access 192.168.1.111 from any other device on the network I get the errors below.
The cfg file includes this:
vif = [ 'mac=c0:ff:ee:aa:ff:ee,bridge=xenbr0â ]
I have also tried
vif = [ 'bridge=xenbr0â ]
I have various other domu machines including an Ubuntu web server that have no problem responding to network requests from other devices on the network.
Any hints valued.
