AFAIK there is no such option.

in domain XML you can change <emulator> tag and point to your script,
which will start domain after some random delay
e.g. something like this:
<domain type='kvm'>
<name>test</name>
...
<devices>
<emulator>/usr/bin/local/qemu-kvm-with-random-delay</emulator>
<devices>
</domain>
# cat > /usr/bin/local/qemu-kvm-with-random-delay
#!/bin/bash
# delay running of virtual machine by 0-9 seconds
sleep $(( $RANDOM % 10 ))
exec /usr/bin/qemu-kvm $*
^D
You can also detect if domain is started by libvirtd autostart feature or not.
it could be enough that you will check if [ -f
/var/lock/subsys/libvirtd ]. But I've not tested.
If you'll have some solution share with us, please.
