[PVE-User] Host interface down; take down bridge/VM-interfaces?

[Joachim Tingvold]

Hi,

Is there a “built in” way to bring down a bridge (or individual
VM-interfaces) if/when the physical interface on the host goes down?
(without having to resort to custom trigger scripts)

Relevant for both containers and VMs, but my current use case is for VMs
specifically.

Single physical interface on host. Using OVS, so either through that, or
through KVM in some way?

I could do PCI passthrough, but I was hoping to avoid that.

        Hi,
I have a debian-9-turnkey-symfony_15.0-1_amd64 container.
Which worked half a year well.
Now, every now and then, the mysql disappears into me.
How is this possible ?
I do not touch or change anything.
Any auto updates inside?
The idea of what this may be caused.
After restoring the base version, everything is ok, for a day, two and
again it sits  ;-/
