My pve version is 6.2-4, using ovs as a virtual switch, there are 4 bridges (vmbr1-vmbr4), which runs a virtual machine with ID 100 as an NFV router (operating system is vyos), vyos from vmbr1 ( Vlan is 1) to vmbr3 and vmbr1 (vlan is 2) to vmbr4 to establish a bridge link, exchange through vyos, vmbr2 is isolated, on vmbr1, created two pno interfaces, respectively pno1-pno2, there is a strange The problem is, I don't know when to start. Whenever I restart some virtual machines (such as windows server or vyos), the entire console network of the pve will stop and I can't enter the background. I know that after a while, the network can automatically recover.

I have 36 virtual machines created in my system, 12 of them are running.
 
I think I have a similar problem. Randomly Everything "freezes" and I can't ping any vms or containers and it only lasts a few seconds. One of my containers is my DNS server so it brings down pretty much everything for a few seconds.
 
This is really a strange problem. What's wrong with it? I hope the official staff can deal with it as a bug. To be honest, I don't know where to submit a bug report.
