Subject: [Qemu-devel] [PATCH] check for active_console before using it
Date: Tue, 18 May 2010 21:45:33 +0200 [thread overview]
Message-ID: <1274211933-20173-1-git-send-email-kraxel@redhat.com> (raw)
Other vga_hw_* functions do the same.
Fixes a segmentation fault. Trigger: boot with -nodefaults,
then connect via vnc.
