Make sure you have click START, when error still exists try to click RELOAD.

NOTE: On latest Java version a dialog box appear which you must click "Don't Block" to continue to run VNC.

and make sure you run latest version, post your 'pveversion -v'

or do you have any firewall blocking ports 5900-99? what OS do you run?

Hello thanks for replay.

The java in this latest version, use the Linux Mint 14, but already tested in other windows OS. I'm with Proxmox installed on a virtual machine in the dropbox.
As for the firewall is blocking not already checked.
Here errors.
TASK ERROR: command '/bin/nc -l -p 5900 -w 10 -c '/usr/sbin/qm vncproxy 100 2>/dev/null'' failed: exit code 2

When error all start virtual machine
TASK ERROR: No accelerator found!

If you have no VT, KVM cannot work. Install on physical hardware with VT or make sure your virtualbox installation support nested virtualization.
