how to find which ips are in use ?

[shukko]

Hello

I've got a 3 host cluster proxmox system running with 12 openvz installations.
Each openvz vm have 3-5 ip addresses each.
I can find them by entering each vm and clicking network tab.
But checking all 12 vm's take time.
Is there an easy way to manage ips given to each vm?

I mean how can I easily list all used ips in my proxmox cluster system and which ip belongs to which vm id ?

Hi,
whats about something like this executed on the master:

hosts=`grep IP: /etc/pve/cluster.cfg | awk '{print $2}'`
for h in $hosts; do
  ssh $h ip=`ifconfig | grep veth | grep -o [1-9][0-9][0-9] | sort -u`;\
         for i in $ip; do \
            echo "ip in $i:"; \
            echo `vzctl exec $i "LANG=C;ifconfig|grep 'inet addr'| grep -v 127.0.0.1"` | awk -F: '{ print $2 }' | tr -d " Bcast"; \
         done
done

I don't have more than one IP per openvz-vm, so i can't test the script.
Of course you can write a smarter script which do the most things in awk...

Thanks Udo but your script is not working, I don't know why.
Anyway
after checking your script I found a better and easy way to achive what I need.
The command I needed is "vzlist"
1 single command:

vzlist -o hostname,ctid,ip

gives me the exact result I needed.

If anybody interested you can read more about vzlist here:
