使用qemu-system-x86_64启动qemu虚拟机的时候只要带上-enable-kvm参数,就会出现"Virtual Machine will not start, ioctl(KVM_CREATE_VM) failed: 16 Device or resource busy"的报错,尝试重新卸载再加载kvm模块也不行,有大佬知道原因或者怎么解决吗? 系统: centos8 (version:8.5.2111,kernel: 4.18.0-348.2.1....

The use of this is no longer supported in system emulators. Support only remains in the command line utilities, for the purposes of data liberation and interoperability with old versions of QEMU. The @code{luks} format should be used instead. @item encrypt.key-secret Provides the ID of...
