Re: [MirageOS-devel] Mirage unikernels and network setup

[Richard Mortier <richard.mortier@xxxxxxxxxxxx>]

Hi Armaël,

Happy New Year!

I’ve no doubt others can answer better than me — it’s a long time since I did 
anything with Mirage on Xen, but it might be useful to include the .xl file 
you’re using to start it? 

Also have you tried from a Linux domU rather than dom0? (ISTR sometimes routing 
being a bit weird from dom0. But as I said, it’s been a while…) Or even just 
waiting a while (several minutes) for ARP to sort itself out?

Thanks!
