Public bug reported:

Description
===========
Multiple Windows virtual machine running on our OpenStack cloud seems to 
occasionally loose the connection from their disk & network virtual device 
(virtio) to the underlying host. The Windows VM is then no longer able to write 
down to the disk (see below for logs). Additionally the network connection is 
shown as "No internet access" (yellow alert symbol). Rebooting the 
corresponding VM fixes the problems.

Steps to reproduce
==================
We don't know how to reproduce the situation.

Expected result
===============
Windows VMs should run without any virtual device connectivity issues.

Actual result
=============
Virtual devices in Windows VMs occasionally loose connection to host, as 
described above.

Environment
===========
Host:
* CentOS Linux release 7.5.1804 (Core) / Kernel: 3.10.0-862
* Nova: openstack-nova-compute-15.1.3-1
* Hypervisor: Libvirt + KVM (Libvirt 3.9.0 / QEMU 2.10.0)
* Storage: Ceph 10.2.10 (5dc1e4c05cb68dbf62ae6fce3f0700e4654fdbbe)
* Networking:  Neutron with OpenVSwitch

VM:
* Windows Server 2016 Standard
* Red Hat VirtIO SCSI Disk Device (Driver version: 10.0.14393.1613)
* Red Hat VirtIO Ethernet Adapter (Driver version: 100.76.104.14900)
* Network: Static IP configuration
