libvirt users - Feb 2017 - How to set manually starting date/time for guest kvm

Hi there,

is there a way to set a guest to start with a specific date and time. (e.g.
when guest boots, starting guest time should always be
(2017-02-05T12:00:00)).

I've tried something like this in my kvm domain:

  <clock offset='variable' adjustment='-86400'
basis='localtime'>
    <timer name='rtc' tickpolicy='delay'
track='guest'/>
    <timer name='pit' tickpolicy='delay'/>
    <timer name='hpet' present='no'/>
  </clock>

However, i can't insert a specific date and time statement (like starting
kvm with -rtc base="2017-02-05T12:00:00").

The date/time must be set before starting the vm and must always be the
same.

Cheers,
Matt

maybe it is easier to use cron

   It doesn't seem to be implemented in libvirt's XML. You can still try
and hack it though: <domain type='kvm'
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
 <qemu:commandline>
     <qemu:arg value='-rtc base="xxx"'/>
   </qemu:commandline>
 </domain>
 It will mark this domain "tainted" in libvirt's log.
