ERROR internal error: Process exited while reading console log output: char device redirected to /dev/pts/45 (label charserial0)
ioctl(KVM_CREATE_VM) failed: 16 Device or resource busy
failed to initialize KVM: Device or resource busy

This is mostly because you have either VirtualBox or VMware running on the same machine. The reason (at least that’s what I think) is that the kernel module of VirtualBox or VMware and KVM can’t take Advantage of Intel VT-x or AMD-V at the same time.

关闭virtualbox等其他虚拟机就好

问题二:

Unable to complete install: 'unsupported configuration: hda-duplex not supported in this QEMU library
Solution One: Virt-Manager

On virt-manager, open the VM’s virtual hardware details menu, go to sound device section, and change the device model from default to ac97.

Click on “Apply” button to save the change. See if you can start the VM now.

也就是 最后一步 “勾选安装之前配置“,完成,然后将声卡改成ac97即可

Solution Two: Virsh

If you are using virsh, not virt-manager, you can edit the VM’s XML file accordingly. Look for sound section inside section, and change the sound model to ac97 as follows.
