求救，虚拟机安装系统时提示error : cannot execute binary /usr/local/bin/qemu-system-x86_64: 权限不够

[runningsnai1]

修改权限后sudo chmod +x /usr/local/bin/qemu-system-x86_64，还是不行
大佬能帮忙看看是什么问题嘛

I had this problem on my Debian and I managed to solve it with these steps:

1. Remove the qemu-img from /usr/local/bin/:

sudo rm /usr/local/bin/qemu-img

2. Verify the correct location of qemu-img from the Debian package:

which qemu-img

It should point to /usr/bin/qemu-img

3. Make sure the correct qemu-img is executable:

ls -l /usr/bin/qemu-img

4. Verify the permissions on the images directory:

ls -ld /var/lib/libvirt/images/

Restart libvirtd:

sudo systemctl restart libvirtd

After doing these steps, try creating your VM again. The system should now use the proper qemu-img binary from /usr/bin/ instead of the one in /usr/local/bin/.

If you still have issues, you might want to check:

sudo virsh pool-list --all
sudo virsh pool-info default

This will verify that your storage pool is properly configured and accessible.

试试看 sudo chmod +x /usr/local/bin/qemu-system-x86_64 呢（？
