Description Tom London 2008-02-26 13:59:28 EST
Description of problem:
System appears not to "pass" Alt-Ctl-Del to the kvm VM.

When I run "qemu-kvm -m 400 image", image boots, and I get the WinXP "enter
Alt-Ctl-Del to start login" window.  But, I see no cursor displayed (unless I
move the cursor, and then only for a second or so), and when I enter
Alt-Ctl-Del, it appears to behave as if I had entered "Alt-Ctl" (that is, the
window loses the grab.

If I run this in full screen mode, still nothing happens when I enter Alt-Ctl-Del.

Reverting to kvm-60-2.fc9.i386.rpm does not fix.  Nor does putting SELinux into
permissive mode.

The X server grabs the Ctrl-Alt-Del  keysequence before any application ever
gets a chance to see it. So its impossible to enter it, unless you use xmodmap
to completely remove X's grabbing of this key sequence.

The other alternative is to use  "Ctrl-Alt-2' to switch to QEMU's admin console
and use its 'send_key' command.

The further alternative is to start QEMU using virt-manager which has a menu
option for sending C-A-D - similarly virt-viewer provides this.

OK. This just stopped working sometime near the end of last week so I thought
"something changed".

There were a lot of X changes, perhaps one of them "broke" this.

I think this needs to be reopened.

qemu-kvm does not display the cursor now too. So even after using the suggested
Ctrl-Alt-2 method to send the key, I can login, but no cursor is display except
momentarily on mouse movement.

Since this is likely not a kvm issue (assuming X), a pointer here so I could
file a BZ properly would be appreciated!
