Thanks for your reply,
$ virsh update-device user user.xml --persistent
error: Failed to update device from user.xml
error: Requested operation is not valid: cannot modify the persistent
configuration of a domain
Without persistent it updates only live password, but in xml it is not modified

Hello,
Is there any way to change VNC password without rebooting virtual machine?
It is available through qemu monitor, but, it seems, there is no way
to do add monitor to kvm.
If you are mean how to do with libvirt.
# cat demo.xml
<graphics type='vnc' port='0' autoport='yes' listen='127.0.0.1'
keymap='en-us' passwd='111111'/>
# virsh update-device demo.xml --persistent
NB, "--persistent" is optional, which is intended to change the vnc
password persistently.
It means "persistent" changing is still not supported. :-)
Regards
Osier
