Whenever the guest machine fails to boot, new parameter (reboot-timeout)
controls whether it should reboot and after how many ms it should do so.
Docs included.

+ <dd>This element controls whether and after how long the guest should
+ start booting again in case the boot fails (according to BIOS). The
+ feature depends on mandatory parameter <code>enabled</enabled> with
+ values <code>yes</code> and <code>no</code>. When enabled, value of
+ the second parameter <code>delay</code> (in milliseconds) controls how
+ long before the boot starts again. Maximum delay is <code>65535</code>
+ milliseconds. <span class="since">QEMU since 0.10.2.</span></dd>
