The server booted up, ran fsck, then each VM, as it booted up ran fsck as well - which just slowed down the whole process since there's a 5 minute delay in starting each VM.
Why would you autostart a VM only every 5 minutes? Or did you mean the next one only started once the earlier one had finished fsck? As mine aren't doing this I haven't ever seen that.
We found (suffered) a 'thundering herd' effect in autostarting all domU's at once where 20 or more were present, and so added control logic to stagger such starts after a reboot (and also track running/stopped state outside of dropping links in the /etc/xen/ directory hierarchy)
