Re: [Xen-devel] Should Qemu monitor be enabled by default

[Hidetoshi Nishi <nishi.hidetoshi@xxxxxxxxxxxxxx>]

Hi all.

On our team side, we would like to resuem the Qemu's monitor and         
serial console as YongKang-san remarks.

For HVM domain, we need Qemu's monitor to install guest's OS from 　　   
multi CDs.

We not make sure that xm block-configure supports to switch CD-ROMs
using latest unstable code.

We would like to keep the Qemu's monitor and serial console until
xm block-configure works well.


Thank you.                                      Nishi
