Re: [Nix-dev] libvirt/nixops (Joachim Schiele)

[Thomas Bereknyei]

I got this working a few weeks ago and had the same issue. Did you modify
your network using `virsh net-edit default'? I think you need to. Mine is:

  default
  some--uuid

That hints the qemu didn't come up, can you paste the contents of files in
/var/log/libvirt/qemu/ somewhere?

Maybe best to open an issue on nixops github and let's continue there!

What's the output of:

$ virsh -c qemu:///system net-dhcp-leases --network default

[Nix-dev] libvirt/nixops

[Joachim Schiele]

dear developers,

i'm using nixos 16.03.1271.546618c (Emu) with nixops 1.4 and i wanted to
deploy to libvirtd. according to
https://nixos.org/nixops/manual/#idm140737319108016 this should be working.

my problem is, i can't manage to get a IPv4 via dhcpcd from a
kvm/libvirtd-client.

i see this:

nixops deploy ...
...
mailserver> waiting for IP address to appear in DHCP
leases.
.


this dottet line never finishes. i've also used virt-manager to deploy a
nixos based guest and using static ip-addresses i can access the
internet from the guest. using dhcpcd from that guest never terminates
successfully either. i see the requests using tcpdump -i virbr0 (on the
host).

this is my host configuration:

  ...
  virtualisation.libvirtd.enable = true;
  networking = {
firewall = {
  allowedTCPPorts = [ 22 80 443 ];
  allowPing = true;
  checkReversePath = false;
};
  };

i'm quite lost now, what could i try to fix this?

best wishes,
joachim
