Re: [MirageOS-devel] Just-In-Time Summoning of Unikernels

[Carlos Oviedo <psxlco@xxxxxxxxxxxxxxxx>]

Hi Magnus,

We are interested to know how the VMs that Jitsu boots up get their IP 
addresses. Are they hardcoded in libvirt domain XML and/or Mirage config 
file?
We are thinking of a dynamic approach where unikernels get their IP from 
a DHCP server and we wonder how to retrieve their IP.
Help will be appreciated, thanks

Kind regards
