[Libguestfs] libguestfs can't communicate over network while creating VM

[Mensik, Petr]

Hello Richard,

I tried what you have adviced (however zzz-dhcp should be replaced by something else or is that right?) and still nothing changes. Btw dhcpcd should be running on the background or is it fine to have just installed (I tried running script with both options - same result unfortunately). Thanks again.

S pozdravem | Best regards

However according to the log libvirt is still complaining that dhcpcd is missing (line 371 in the log). I ran dhcpcd command on both machines and I've even restarted networking service - unfortunately nothing helps. So I'd like to ask you for help or at least any hints. Thanks a lot.

Most likely dhcpcd is not being copied into the appliance.

Try doing:

  echo dhcpcd > /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/zzz-dhcp
