Package: libvirt-daemon
Version: 1.2.9-9+deb8u1
Severity: normal
Dear Maintainer,
I'm using libvirt to virtualize a VM on my laptop, this vm has to be bridged on
the network and I'm using macvtap technology (trough virt-manager)
here is the xml part of the domain regarding network:
<interface type='direct'>
<mac address='52:54:00:7f:de:65'/>
<source dev='eth0' mode='bridge'/>
<target dev='macvtap0'/>
<model type='virtio'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>
</interface>
<interface type='network'>
<mac address='52:54:00:49:cb:48'/>
<source network='priv'/>
<target dev='vnet0'/>
<model type='virtio'/>
<alias name='net1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07'
function='0x0'/>
</interface>
When the laptop boot and I start the VM, there's no problem.
But when I put the laptop to sleep, the macvtap interface will never get up
again.
I even tried to stop the vm, libvirt, unload modules (macvtap, vhost_net,
vhost, e1000e), but nothing help.
The only way to get it back working is to reboot the host os (like Windows,
booohooo :-( )
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
I'm not sure, either unplug/plug the ethernet connection (like removing the
laptop from its docking station), or put laptop on sleep and wake him.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Appart a reboot, nothing effective.
* What was the outcome of this action?
* What outcome did you expect instead?
When the system is wokring, the macvtap interface is "UP", but when the problem
occurs the interface is "DOWN". Of course a "ip link set macvtap0 up" or delete
interface and recreate them did not help.
The only thing I founded in the log is this message:
IPv6: ADDRCONF(NETDEV_UP): macvtap0: link is not ready
