I can safely say this is not related to intel microcode, I see this happening since a short while on one of our clusters as well, which is fully AMD nodes.
As far as I know, on windows this is a "domain policy" pushed by the Active Directory. The windows domain policies don't work on anything but windows. Technically you can change the policy (GPT editor) to change the NTP server to something other...
When synchronized with NTP, the RTC is typically not referenced.
For example, in Windows, it is referenced at startup. Once synchronization with NTP begins, the RTC is never referenced again. If synchronization with NTP has not started, it...
I don't know VMware but for Linux VM you can use ptp_kvm as the clock source: https://forum.proxmox.com/threads/how-to-enable-continuous-time-sync-between-qemu-guest-and-host.173396/#post-806460
Not sure if it is 'The' recommended way, but as I mentioned, we rely on a NTP source in our network so it is reachable for all machines. In your case if you do not have the means to set up a dedicated NTP source, using one of the PVE hosts, or...
This is not an 'ntp' option, this is for the startup of the vm, windows likes to have the system date/time in the local time zone, while *nix OS likes to have the system date/time in UTC. This option translates the host time for the vms to the...
in our env we run chrony on all linux vpms using ptp_kvm and that works very well. For windows we currently just sync with the NTP server in our network, which is also used by the pve hosts. The reason for using ptp_kvm is that is has less...
New information.
had 2 reboots of hosts this weekend, same host both times, what is weird from the 2nd reboot, we have a very clear "OOM" problem. however our host at the moment has 3x the amount of memory provisioned all vm's combined are...
For my side, had another reboot this friday, 2 PVE hosts. We traced the issue to our ceph HDD pool which is being slow at that moment. Were moving some copy/sync which is going to the HDD pool to be more stretched out and not all hosts hitting it...
