This is on merlot0... Can't that thing even boot on time now?!?! :-O

Looking at the serial log here:
http://logs.test-lab.xenproject.org/osstest/logs/60107/test-amd64-amd64-xl-multivcpu/serial-merlot0.log

The biggest 'skip' in the timestamps I've found is this:

  Jul 29 18:39:21.753156 Starting NTP server: ntpd.
  Jul 29 18:39:49.681201 Starting /usr/local/sbin/xenstored...

That did not happen during the previous (baremetal) boot:

  Jul 29 18:32:40.521077 Starting NTP server: ntpd.
  Jul 29 18:32:40.745125 Starting periodic command scheduler: cron.

It looks like, in general, such thing is slower under Xen, but by how
much, it varies quite a bit (also, some of the lines are mangled):

  Jul 29 07:06:46.497115 Starting NTP server: ntpdStarting /usr/local/sbin/xenstored...
  Jul 29 07:07:05.145127 Setting domain 0 name, domid and JSON config...

  Jul 29 08:13:28.549079 Starting NTP server: ntpd.
  Jul 29 08:13:31.917273 Starting /usr/local/sbin/xenstored...

  Jul 29 08:59:05.309143 Starting NTP server: ntpd.
  Jul 29 08:59:07.757168 Starting /usr/local/sbin/xenstored...

Infra/transient issues?

Regards,
Dario
