Hi,

I've two server running on qemu, there are connecte via tun/tap. I try 
to save the vm state and then restart the servers from vm state. The vm 
start correctly but the the networkin doesn't work. I don't know, 
perhaps my scripts are wrong?!

phase 1 (first boot)

brctl addbr link1

qemu -hda PC1.cow -hdb fat:qemuconfigs/pc1  -net 
nic,macaddr=00:ab:cd:7a:91:8c -net 
tap,script=pc1.eth1.sh,ifname=pc1.eth1 -net 
nic,macaddr=00:ab:cd:28:14:c1 -net 
tap,script=pc1.eth0.sh,ifname=pc1.eth0 -m 128 -serial 
tcp::3001,server,nowait -monitor tcp::4001,server,nowait

qemu -hda PC2.cow -hdb fat:qemuconfigs/pc2  -net 
nic,macaddr=00:ab:cd:51:66:69 -net 
tap,script=pc2.eth0.sh,ifname=pc2.eth0 -net 
nic,macaddr=00:ab:cd:2b:97:d7 -net 
tap,script=pc2.eth1.sh,ifname=pc2.eth1 -m 128 -serial 
tcp::3000,server,nowait -monitor tcp::4000,server,nowait

the tap scripts :

pc1.eth0

#!/bin/sh
ifconfig $1 0
sudo brctl addif link1 $1

pc1.eth1

#!/bin/sh
ifconfig $1 0

pc2.eth0

#!/bin/sh
ifconfig $1 0
sudo brctl addif link1 $1

pc2.eth0

#!/bin/sh
ifconfig $1 0

# at this point I can ping each vm

phase 2 (save vm state):

from each vm :

ctrl+alt+2, then
savevm pc1.stm
savevm pc2.stm

phase 3 (stop vm and delete the bridge) :

brctl delbr link1

phase 3 (reboot the vm and the network from state machine):

brctl addbr link1

qemu -hda PC1.cow -hdb fat:qemuconfigs/pc1  -net 
nic,macaddr=00:ab:cd:7a:91:8c -net 
tap,script=pc1.eth1.sh,ifname=pc1.eth1 -net 
nic,macaddr=00:ab:cd:28:14:c1 -net 
tap,script=pc1.eth0.sh,ifname=pc1.eth0 -m 128 -serial 
tcp::3000,server,nowait -monitor tcp::4000,server,nowait -loadvm pc1.stm

qemu -hda PC2.cow -hdb fat:qemuconfigs/pc2  -net 
nic,macaddr=00:ab:cd:51:66:69 -net 
tap,script=pc2.eth0.sh,ifname=pc2.eth0 -net 
nic,macaddr=00:ab:cd:2b:97:d7 -net 
tap,script=pc2.eth1.sh,ifname=pc2.eth1 -m 128 -serial 
tcp::3001,server,nowait -monitor tcp::4001,server,nowait -loadvm pc2.stm

# the vm starts buts it's impossible to ping vm ... what's happend?? And 
sometimes I get this error : eth0 mismatched read page pointers 4c vs 5e.

what's wrongg????!!

Thank you

-Francis
