Netctl bridge config don't work and shut all interface down

Hello Arch users !

Yesterday I tried setup a bridge for KVM+Qemu on my Arch server, but after I enabled and started the bridge, arch no longer have network activities...
And after some research I figured out than the command :

# ip link set net0 up

Just set net0 and br0 to up and after something like 5-10 secondes all interfaces can ping without any troubles...
Then I tried use the netctl options "ExecUpPost" to use the command automatically but that don't work and I need to input in myself on the plugged keyboard...

So this is my 2 netctl profiles :

Description='Static ethernet connection'
Interface=net0
Connection=ethernet
IP=static
Address=('192.168.1.250/24' '192.168.1.251/24' '192.168.1.252/24' '192.168.1.253/24')
Gateway='192.168.1.1'
DNS=('192.168.1.250' '1.1.1.1' '1.0.0.1')

## For IPv6 autoconfiguration
IP6=no

#ExecUpPost="ip link set net0 up"

Description="Qemu Bridge"
Interface=br0
Connection=bridge
BindsToInterfaces=(net0)
IP=static
IP6=no
Address='192.168.1.100/24'
Gateway='192.168.1.1'
## Ignore (R)STP and immediately activate the bridge
SkipForwardingDelay=yes

#ExecUpPost="ip link set net0 up"

Thanks in advance !
