On RHEL5.1, Virtual Machine doesn't enable qemu console of HVM.

I found there was a conflicted definition in RHEL5.1 RC release note.
Because Qemu monitor can not work in RHEL5.1, so following sections should be
removed from release note.

     o Installing a fully virtualized guest using split installation media --
       specifically, multiple CD-ROMs -- may fail when required to switch
       between installation CDs. During the guest OS installation process,
       users may be prevented from mounting or ejecting installation CDs,
       which prevents the installation from completing.

         3. Switch to the QEMU monitor console by pressing Ctrl-Alt-2.

         4. Run the command eject hdc.

         5. Run the command change hdc <path to the CD-ROM in host system>.

         6. Switch back to the guest OS console by pressing Ctrl-Alt-1.

       Note that when using a regular VNC client the host X server may
       encounter some difficulty interpreting the Ctrl-Alt-2 and Ctrl-Alt-1
       command. To work around this in virt-manager, use sticky keys.
       Pressing Ctrl three times makes it "sticky" until the next
       non-modifier is pressed. As such, to send Ctrl-Alt-1, press Ctrl twice
       before pressing Ctrl-Alt-1.

The release notes are bogus. The QEMU monitor console is disabled as it is a
huge security hole if accessible over VNC. This release note needs to be removed.

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update

hmmm... this note is no longer in the RHEL5.1GA release notes. what we do have,
however, is this:

Installing Red Hat Enterprise Linux 5.1 using split installation media (for
example, CD or NFSISO) no longer causes an error in the installation of

i tried searching through the RHEL5.1 release notes and couldn't find the string
"QEMU" either. i'm closing this bug as CLOSED CURRENTRELEASE then.
