A Windows guest with virtio-win unexpectedly lost a network interface.
There were no error messages in /var/log/messages or in /var/log/libvirt/qemu/
# /var/log/libvirt/libvirt.log ...(snip)... <date/time>: 2674: warning : qemuMonitorJSONHandleDeviceDeleted:950 : missing device in device deleted event ...(snip)... # /var/log/messages ...(snip)... <date,time,host> kernel: device vnet11 left promiscuous mode <date,time,host> kernel: bridge0: port 2(vnet11) entered disabled state ...(snip)...
We think that the above messages are the same as a pattern of removing VM's device using libvirt. But, our customer said that they executed nothing.
- Is this issue a bug about libvirt or qemu-kvm?
- What is a root cause of this issue?
- Are there any workarounds of this issue?
