Red Hat Bugzilla – Bug 245284
can not use the monitor of Qemu-dm
Last modified: 2007-11-30 17:12:08 EST
Description of problem:
We can not use the monitor of Qemu-dm that I want to use to change the
CD-ROM at installation.
On current Xen, we need to set the monitor flag to ON when we want to use
the monitor of Qemu-dm.
But the libvirt does not set that flag, so we can not use the monitor.
This is the help of xm:
# xm create --help_config:
> monitor=no|yes Should the device model use monitor?
And this is the example of setting the flag ON:
(monitor 1) <--setting to ON
Version-Release number of selected component (if applicable):
libvirt 0.2.3 (ChangeLog:revision 1.596)
Steps to Reproduce:
1. install the guest of HVM domain using the virt-install or virt-manager
2. hold the "[ctrl]+[alt]+" down to use the monitor of Qemu-dm
on the vncViewer
We can not use the monitor of Qemu-dm.
We can use the monitor of Qemu-dm.
I attached the patch that set the monitor flag to 1(ON) if the guest
domain is HVM and the xendConfigVersion is 4 or later.
In the future, I want to be able to select ON/OFF of the monitor in view
of the security.
Created attachment 157596 [details]
set the monitor flag to on
Turning on the monitor is a security hole. We will not add any option to
virt-manager to turn on security holes.
If you have specify actions you wish to be able to perform (eg changing the
CDROM media) please enter BZ tickets for each action, so we can be provide a
sensible secure implementation that does not involve the monitor
