kvm錯誤：failed to initialize KVM: Permission denied

錯誤1：

啟動kvm容器報錯：

# 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

解決：

1、查看/dev/kvm權限，如果權限不對，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"

重啟libvirtd服務
#systemctl restart libvirtd
