unhandled vm exit: 0x80000021

[Jorge Boncompte [DTI2]]

    Hi,

    My kvm/qemu setup exits realiably with the error from the subject every 
time that I do a reboot at the guest. Aside from this annoyance kvm/qemu 
works pretty well on my workload.

    HOST: Debian (etch) + kernel.org 2.6.20 (32bits) + kvm-14
    GUEST: Custom embedded distribution + kernel.org 2.4.32
    CPU:  Intel Pentium D 3.2Ghz
    CMDLINE: /usr/local/bin/qemu -hda /images/loop1.img -k es -serial 
stdio -net nic,model=rtl8139,macaddr="52:54:00:$(date +%T)" -net 
tap -std-vga -no-acpi -nographic

--------------------
The system is going down NOW !!
Sending SIGTERM to all processes.
Please stand by while rebooting the system.

The issue is known.  It is already fixed (at least partially) on AMD 
hosts, and I plan a fix for Intel, though it will take some time for me 
to reach it.
