This is an example of using static ip address:
1. edit ifcfg-eth0 of guest to assign static IP
(192.168.100.110). You can also do this by install
post-script/serial.
2. add and setup bridge in host
# brctl addbr vbr
# ifconfig vbr 192.168.100.1
3. add script for setup tap device
/etc/qemu-ifup-vbr
| #!/bin/sh
| switch=vbr
| /sbin/ifconfig $1 0.0.0.0 up
| /usr/sbin/brctl addif ${switch} $1
| /usr/sbin/brctl setfd ${switch} 0
| /usr/sbin/brctl stp ${switch} off
4. assign parameters in config file and execute test as usual
test.cfg:
| ip_nic1 = 192.168.100.110
| mac_nic1 = 11:22:33:44:55:67
| bridge = vbr

Yeah, it's my fault.
Let's wait for other comments and send a v2 later.

oops, Amos, better to comment out this line in patch, if this patch applied,
all nic1 will use this static ip, it interrupts our normal testing process.
Who need the static ip should add this line by himself.

[PATCH] virt-test: support static ip address in framework
Sometime, we need to test with guest(s) which have static ip
address(es).
eg. No real/emulated DHCP server in test environment.
eg. Test with old image we don't want to change the net config.
eg. Test when DHCP exists problem.
This is an example of using static ip address:
1. edit ifcfg-eth0 of guest to assign static IP
(192.168.100.110). You can also do this by install
post-script/serial.
2. add and setup bridge in host
# brctl addbr vbr
# ifconfig vbr 192.168.100.1
3. add script for setup tap device
/etc/qemu-ifup-vbr
| #!/bin/sh
| switch=vbr
| /sbin/ifconfig $1 0.0.0.0 up
| /usr/sbin/brctl addif ${switch} $1
| /usr/sbin/brctl setfd ${switch} 0
| /usr/sbin/brctl stp ${switch} off
4. assign parameters in config file and execute test as usual
test.cfg:
| ip_nic1 = 192.168.100.110
| mac_nic1 = 11:22:33:44:55:67
| bridge = vbr
