Failed to retrieve dnsmasq leases from /var/lib/libvirt/dnsmasq/docker-machines.leases

docker-machine-driver-kvm version v0.10.0

When running:

docker-machine -D create -d "kvm" default

I get the following:

(default) DBG | Creating VM data disk... (default) DBG | Creating 20000 MB hard disk image... (default) DBG | Defining VM... (default) DBG | Starting VM default (default) DBG | GetIP called for default (default) DBG | Failed to retrieve dnsmasq leases from /var/lib/libvirt/dnsmasq/docker-machines.leases (default) Failed to decode dnsmasq lease status: unexpected end of JSON input (default) DBG | Unable to locate IP address for MAC 52:54:00:6c:d5:d8

As can be seen the ISO downloads and the VM starts. I can see the VM in virt-manager and also connect to it. The lease failure repeats until it times out. I have no /var/lib/libvirt/dnsmasq/docker-machines.leases file present. The assumption is that the failure is because that file is missing but what is supposed to be creating that file in the process and any idea why it isn't being automatically created? Using virsh net-dumpxml I can see "docker-machines" and it has the following configuration:

docker-machines 221c842f-27b9-4b17-83d2-f9233971bb9e

Using virsh net-list it shows with an active state.

I experience the same issue since some days. After a stop of the VM the VM cannot be started again, because it hungs on the following issue until it timeouts.

i think it's addressed by https://github.com/dhiltgen/docker-machine-kvm/pull/63

I got the same error message. Was there a resolution released for this? I'm using Ubuntu 16.04 LTS without any special configuration and KVM.

Minikube is working fine with its KVM2 driver.

[wadadli]

It's deprecated, use the kvm2 driver.
