Hello all,
I have removed a network card on the server and now the problem that I can no longer make a networkconfiguartion.

I had put the bridge on an internal port (eno1) works it does the vms and containers are also accessible and communicate.
Only I can not create a new because no vmbr is announced to me.

I hope someone can help.

My interfaces looks like this:


Code: 
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual

auto eno2
iface eno2 inet manual

auto eno3

auto eno4

        address 10.10.10.88/24
        gateway 10.10.10.1
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0


ip a outputs the following:

HI,
your network configuration looks fine.

what exactly do you mean by that? There is no bridge to select in the VM creation wizzard? Do you get an error?

Please post the output of brctl show

Okay, something is off here! How exactly did you modify the network configuration? Did you perform a ifreload -a or did you reboot after changing the config?

Please post the output of pveversion -v and pvesh get nodes/localhost/network
 
i have edited the interfaces via winscp and transferred the data from the old port of the old card (ensf06) to eno1, deleted the old ports and then saved. shut down the server and removed the old card. then restarted the server.

A communication afterwards was also immediately possible only since then I have old the problem that I can not create new vms and cts.

ifreload -a I have already run several times without error.
I have not yet made a reboot.

Here are the queries:

Okay, so no worries there.

Please try to log out of the WebUI, clear the browser cache and log back in. You could also try to login via an incognito tab. Does the problem persist after these steps? Do you get any errors in the browsers developer tools?
 
Code: 
auto vmbr0
iface vmbr0 inet static
        address 10.10.10.88/24
        gateway 10.10.10.1
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

do you use tab in front of address,gateway,.... ? because you can't use space here, you need 1 tab.
