when I was trying to start my first created vm, i faced the same issue as discussed in this thread https://forum.proxmox.com/threads/cant-start-vms.13824/
so I initially followed the thread and managed to created a bridge vmbr0 , I faced the problem because I created the pve install using vagrant.
I confirmed that vmbr0 does not exist using brctl command i.e
after confirming I followed the above linked thread and then tried after confirming I followed the above linked thread and then tried
this errored as shown below
but to my surprise I when I typed in
the vmbr0 bridge was created.
and I was able to start my vm using the command
but since in my pve installation the networking service is still not running, I tried reverting to original interfaces file shown below
but the networking service is still not starting please guide me how should I fix this what what is going wrong here !
thank you in advance
