Good evening.

Good evening.

Please tell me how to disable the PROMISC mode for tap interfaces for the created and enabled virtual machine, as well as when creating a virtual machine
Bash:
207: tap100002i0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master fwbr100002i0 state UNKNOWN group default qlen 1000

Or maybe you have a best practice so that the virtual machine sees only the traffic intended for it, at the moment I am watching the traffic of other people's machines located on the same proxmox hypervisor
 
Hi,

Using `ip` you can disable it, as the following example, but may you tell us why you want to disable the `promisc`?

Bash:
ip link set tap100002i0 promisc off
