qemu-system-ppc64沒有對等警告，而試圖啓動，並提出以太網接口

Question

我想模擬使用QEMU PPC64e5500 CPU，但試圖調出機器中的以太網接口我得到沒有對等警告。

$sudo ~/QorIQ-SDK-V1.6-20140619-yocto/build_t1040rdb_release/tmp/sysroots/x86_64-linux/usr/bin/qemu-system-ppc64 -cpu e5500 -nographic -m 256 -M ppce500 -kernel uImage -initrd fsl-image-minimal-t1040rdb-20141223093206.rootfs.ext2.gz -append "root=/dev/ram rw console=ttyS0,115200 ip=192.168.7.2::192.168.7.1:255.255.255.0 mem=128M" -serial tcp::4444,server,telnet -net nic -net tap,ifname=tap0,script=no,downscript=no -device e1000 

上述命令的輸出如下

QEMU 1.7.0 monitor - type 'help' for more information 
(qemu) QEMU waiting for connection on: telnet:0.0.0.0:4444,server 
Warning: nic e1000.0 has no peer 

現在給出甚至在機器啓動它報告

    host=192.168.7.2, domain=, nis-domain=(none) 
    bootserver=255.255.255.255, rootserver=255.255.255.255, rootpath= 

由於它報告8021q：添加VLAN 0到HW過濾設備eth0，所以我甚至無法ping通網關，因爲可以驗證下面的網關

root@model:~# ping 192.168.7.1 
PING 192.168.7.1 (192.168.7.1): 56 data bytes 

--- 192.168.7.1 ping statistics --- 
3 packets transmitted, 0 packets received, 100% packet loss 

路線-n顯示如下輸出

root@model:~# route -n 
Kernel IP routing table 
Destination  Gateway   Genmask   Flags Metric Ref Use Iface 
0.0.0.0   192.168.7.1  0.0.0.0   UG 0  0  0 eth0 
192.168.7.0  0.0.0.0   255.255.255.0 U  0  0  0 eth0 

那麼，爲什麼eth0已經被添加到該VLAN，因爲即使我沒有創建一個，以及如何解決它的任何想法。

Answer 1

我不知道CPU e5500，但對於ppc64，我已經非常成功地使用設備spapr-vlan。

這是QEMU行我用：

qemu-system-ppc64 -enable-kvm -nographic -nodefaults -monitor stdio -serial pty -M pseries -smp 1,cores=1,threads=8 -m 4G -device spapr-vlan,netdev=net0,mac=4c:45:42:45:02:02 -netdev bridge,id=net0,br=br0
