[SOLVED] qemu - authorization required

When I run sudo qemu-img create -f qcow2 ./myimg.qcow2 24M, it gives

Formatting './myimg.qcow2', fmt=qcow2 cluster_size=65536 extended_l2=off compression_type=zlib size=25165824 lazy_refcounts=off refcount_bits=16

and then sudo qemu-system-x86_64 -hda ./myimg.qcow2 -cdrom ./image.iso -usbdevice tablet, it says

Authorization required, but no authorization protocol specified
Unable to init server: Could not connect: Connection refused
gtk initialization failed

Would you see were the mistake is? The -usbdevice tablet option seems to be to emulate the mouse, if I understood well.

Just sudo qemu-system-x86_64 -hda ./myimg.qcow2 doesn't work already. The libvirtd service is running without error.

You don't need sudo to use 'qemu-img create' or ' qemu-system-x86_64'
