kvm错误：failed to initialize KVM: Permission denied

错误1：

启动kvm容器报错：

# virsh start hadoop-test
error: Failed to start domain hadoop-test
error: internal error: process exited while connecting to monitor: Could not access KVM kernel module: Permission denied
failed to initialize KVM: Permission denied

解决：

1、查看/dev/kvm权限，如果权限不对，改成如下：

#chown root:kvm /dev/kvm
#chmod 666 /dev/kvm

2、修改/etc/libvirt/qemu.conf

#user="root"

user="root"

#group="root"

group="root"

重启libvirtd服务
#systemctl restart libvirtd
