第一篇文章,感谢社区。 如果它更适合在另一个论坛上而道歉
我正在运行Ubuntu 12.04 LTS Server作为我的主机。
/ etc / libvirt #kvm --version
QEMU模拟器版本1.0(qemu-kvm-1.0),版权所有(c)2003-2008 Fabrice Bellard
我构建了一个运行Ubuntu 13.10的虚拟机。 当我进入XML为静态IP配置以太网tap0接口时,我遇到了麻烦。 我已经搜过网并尝试了几件事,但无济于事。
这是我得到的错误。
错误下面是我的配置和我的日志
在那之下是我尝试过的事情清单,并没有取得成功......
- #virsh启动phabVM
错误:无法启动域phabVM
错误:内部错误读取控制台日志输出时退出进程:char设备重定向到/ dev / pts / 1
kvm:-netdev tap,ifname = tap0,id = hostnet0:无法打开/ dev / net / tun:不允许操作
kvm:-netdev tap,ifname = tap0,id = hostnet0:设备'tap'无法初始化

将用户添加到组kvm
配置libvirtd.conf并取消注释listen_tls和listen_tcp
通过将root设置为user / group来配置qemu.conf以运行VM&取消注释
clear_emulator_capabilities = 0
禁用apparmor
确保kvm二进制设置为kvm组
答案 0 :(得分:0)
尽量不要使用<interface type="ethernet">
,还有更多various possibilities to use for network interfaces更安全,更易于管理等。如果确实需要使用以太网类型的界面,然后你可以完全按照libvirt wiki page关注那个问题,但我必须强调一点,我不推荐这个。
