Hyper-V manager very very slow to open vm properties

Hi,

I'm using Hyper-V, and I have 3 clusters composed of 15 to 20 Hyper-V hosts per cluster.

For each VM, I have a dedicated volume on PureStorage array technology. All my Hyper-V hosts are running Windows 2022 (November Update). When I try to load the settings page of a VM (right-click on the VM in the list and then select 'Settings...'), the window opens and shows 'loading in progress' on the left. This can take between 10 to 50 minutes!!! This problem is on all VM. This happens both via the Hyper-V Manager and via the Cluster...

There are no errors in the Windows event viewer. If I run PowerShell commands like Get-VM or if I want to obtain the storage or network details of a VM, it's almost instantaneous...

I'm not sure since when this issue has been occurring, but we upgraded all our Hyper-V hosts to Server 2022 and installed PureStorage over an entire weekend. Since these modifications, we've been experiencing this problem. However, the VMs themselves are running fine with no issues in that regard.

    Hi Benjamin, Hope you're doing well. Please follow the following steps: 1. Check Network Latency: Verify the network latency between the Hyper-V Manager client and the Hyper-V hosts. High network latency can cause delays in loading the settings page. 2. Check PureStorage Configuration: Confirm that the PureStorage array configuration is correct and that there are no issues with the storage connectivity. 3. Update Hyper-V Integration Services Make sure that the Hyper-V Integration Services are up-to-date on the virtual machines. Integration Services help improve communication between the host and guest operating systems. 4. Review Hyper-V Host Logs: Check the logs on the Hyper-V hosts for any errors or warnings that might be related to the issue. Event Viewer and Hyper-V logs could provide useful information. 5. Check for Windows Updates: Confirm that all Hyper-V hosts and the management workstation have the latest Windows updates installed, including cumulative updates. 6. Examine Antivirus or Security Software: Temporarily disable any antivirus or security software on both the Hyper-V hosts and the management workstation to see if it has any impact on the loading time. I hope this helps. Best Regards, Ian Xue
