Ubuntu下用libvirt安装KVM虚拟机时找不到/bin/qemu-kvm问题解决

启动虚拟机的时候老出现：error: Cannot check QEMU binary /bin/qemu-kvm: No such file or directory
我用的是以下xml配置文件
<domain type='kvm'>
<name>rheltest</name>

在没有找到/bin/qemu-kvm这个文件，后来才知道，对Ubuntu的应该对应是/usr/bin/qemu这个文件，把上面xml配置文件对应的那行改为如下就行了
<emulator>/usr/bin/qemu</emulator>
