Thanks,
>>By the way,I also want to use USB-redirect function,But I
found
the function option is grey......
<<<That could happen for different reasons. - Is your client running on windows
or linux machine? - Is the VM configured for USB? Look for 'USB redirection' in
the link above.
>>The stages:
1.enable VM's usb support on web
manager.
2.choose SPICE as remote protocol.
3.use console to connect VM as administrator or use vm via user portal .
problem:
Found that the option of usb-redirect is grey.
