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??
what's wrongg????!!
Thank you
-Francis
