Vnet disappears in bridges

[WolfAURman]

Hello everyone!
I have a problem - when adding a vnet network to a bridge with a physical network card, the vnet disappears from the bridge after a while. There are no errors in the logs, all known configurations have been reset (network interface configurations, and libvirt settings)

OS info:

VERSION="9.3 (Blue Onyx)"
ID="rocky"
ID_LIKE="rhel centos fedora"
VERSION_ID="9.3"
PLATFORM_ID="platform:el9"
PRETTY_NAME="Rocky Linux 9.3 (Blue Onyx)"

How to fix it, and is it possible? I’m sorry for the stupid question

After filtering the logs, NetworkManager realized that bridge was waiting for an IP address to be received via DHCP. Setting a static IP address fixed the problem of dropping the vnet network. It’s strange that this appeared after a recent reboot, because bridge used to receive an IP address from pfSense in a virtual machine, but well, the main thing is that I found a solution to the problem
