Hi,
I'm unsure if this is the correct place to ask this, but I have a very strange problem and no idea about the cause and how to fix this.
In the last few weeks my 3 node test cluster (PVE 6.3-6) had several external caused outages (power and heartbeat network issues).
As a result I had some KVM-Windows-Machines mysteriously lose their network configuration which has never happened before.
The affected Guest-OS versions are Server 2008R2 (i know!), Server 2019 and even Windows 10 20H2.
There was a new network adapter appearing inside the Windows-Guest (Red Hat VirtIO Ethernet Adapter #2 or even #3), which was set to DHCP.
After I reconfigured the adapter to it's previous fixed IPv4-Address, it said that there already is another adapter with this IP address.
When I check the nonpresent devices in Device Manager the additional VirtIO-Adapters are still there but disconnected.
I'm using VirtIO-Drivers 0.1.171 and did not change anything on the KVM-Guest's or PVE-host's configuration.
That happened three times now and I have no idea why this is happening or which logfiles to check.
Does anyone have an idea how to track this down?
Thank you
