[libvirt-users] QEMU monitor
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. -- Nikita A Menkovich http://libc6.org/ JID: menkovich@gmail.com

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. Regards Osier
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 2011/3/14 Osier Yang <jyang@redhat.com>:

It means "persistent" changing is still not supported. :-)
