[Qemu-devel] [BUG] network : windows os lost ip address of the network card in some cases

[yin.zuowei]

we  found this problem for a long time 。For example, if we has three network 
card in virtual xml file ，such as "network connection 1" / "network connection 
2"/"network connection 3" 。

Echo network card has own ip address ，such as 192.168.1.1 / 2.1 /3.1 , when 
delete the first card ，reboot the windows virtual os, then this problem 
happened !




we found that the sencond network card will  replace the first one , then the 
ip address of "network connection 2 " become 192.168.1.1 。


Our third party users began to complain about this bug 。All the business of the 
second ip  lost !!! 

I mean both of windows and linux has this bug ,  we solve this bug in linux  
throught bonding netcrad pci and mac address 。

There is no good solution on windows os . thera are ?  we implemented a plan to 
resumption of IP by QGA.  Is there a better way ?
