Description of problem: Old versions of the RHEV Admin guide (https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.0/html/Administration_Guide/KVM_Clock_Appendix.html) make references to "USEPLATFORMCLOCK" however, this is not mentioned in newer versions of the admin guide. When Windows VMs have snapshots taken, they are paused for a short amount of time. When the VM comes back, the time is out somewhat. How do we tell Windows VMs to use the hypervisors clock? The versions of Windows affected are Windows 2008R2 and above. Additional info: Following is current documentation link : Using the Real-Time Clock with Windows virtual machines: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.5/html-single/Administration_Guide/index.html#KVM_virtual_machine_timing_management but boot.ini no more used after windows XP.
hm, regardless doc updates this is something we can try to help with automatically as well. We have a guest agent and that one can try to do that for you. Let me clone this to a guest agent RFE
oVirt 4.0 Alpha has been released, moving to oVirt 4.0 Beta target.
Closing this now, as no further information was provided, and we don't mention USEPLATFORMCLOCK at all in the RHV 4.0 or 4.1 documentation.
