Re: [libvirt-users] Clock skew on Win10

Hi, I haven't received any replies to this, but I'm still having a
problem with clock skew on Win10.

How can I troubleshoot this? I'm pretty sure the clock settings are
correct from within Windows, but when the VM resumes from the host
sleeping, the clock is off by some seemingly random number of hours.

Hi Alex, I think your problem is very common and has no
easy solution. It is normal that the virtual machines have
not advanced the clock after hibernation. You have to run
a process that updates it or you can call it from a script.

We work with Perl and we ended up using the set_time function
to force it. It requires the vdagent installed in the virtual
machine . We call it after resume:

   $domain->set_time(time(), 0, 0);

You also need the guest agent channel in the XML definition
of the virtual machine

<channel type='unix'>
      <target type='virtio' name='org.qemu.guest_agent.0'/>
      <address type='virtio-serial' controller='0' bus='0' port='2'/>


Hope this helps.
