Nut upsuser - Jun 2017 - Best way to shut down RH KVM/QEMU based VMs via NUT

Hey there,

 Has anyone tackled the best way to shut down a VM running Win10 running in
RedHat's (CentOS 7) KVM/QEMU VM manager?

I'm looking at this link to follow:


https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Virtualization_Deployment_and_Administration_Guide/sect-Managing_guest_virtual_machines_with_virsh-Shutting_down_rebooting_and_force_shutdown_of_a_guest_virtual_machine.html

but thought I'd ask the group if they found any other cool tricks or
pitfalls...

Cheers,


 -Ben

Hi Ben,

On RHEL/CentOS 7, libvirt-guests (which comes from libvirt-client) on the
host controls the suspend vs. shutdown behavior of the guests.  By default
the guests suspend, but if you want them to shutdown, change the
ON_SHUTDOWN setting in /etc/sysconfig/libvirt-guests.  I don't have any
Windows guests, but the linux guests work nicely with the default suspend.
That said, I have only recently begun to see an issue with one of my
CentOS7 guests being resumed with incorrect time--haven't gotten to the
bottom of that one yet.

Excellent!

Thank you.

As for your time issue, I  might be able to help there.

As it already stands, KVM/QEMU (and linux) handles the hardware RTC time in UTC
and Windows seems the like handling it in local time.

When I build this Win10 VM, it always came up the timezone+/- DST off.

I had to add a Windows registry setting to tell it the RTC was UTC and not
Local.

did you do this yet? (just wondering if it'll help if you haven't.)

Cheers,

Oh - I realized when I hit send - you were having issues with non-windows.

Nevermind my previous post.... unless you decide to run Windows. :P
