So....................... it is dynamic memory causing me problems.

I have have set the min/max and static memory to the be same. The system stays up fine.

Now to figure our how/if I need dynamic memory to work on a Windows VM. I do not seem to be having problems with linux based workloads.

@kassebasse It only stays up for five minutes or so. It is not around for long enough to take a backup.

@dinhngtu Ah, good point. I will check to see if there were drivers installed for Proxmox/ESXi. I guess it would possible that there are some left there.

I have not attempted to install any XCP drivers on the VM. Might that be a resolution?

I am using a new and fresh XCP-NG 8.3 install. Storage is on a Synology NAS with Intel DS SSDs and using a 10GBe network to the XCP hosts.

I have migrated a Windows 2019 server from Proxmox by moving and running qemu-img on the files. Originally this VM was installed on ESXi and was migrated into Proxmox.

The problem:

• the Windows 2019 server restarts every few minutes. After a few minutes it reboots. This cycle repeats and repeats.

• the network when it is up is not great . There are mised and delayed responses to a ping

• no other VM has this problem

• I have tried migrating from different VMDK files and backups. The same result

• There are no obvious mistakes in the XCP config

• I have checked all the logs in the XCP hosts. There is nothing obvious. I can provide anything more if needed

• A fresh install of Win2019 in XCP works fine.

I am not sure where to go next...

Is this problem resolvable? I am tempted just to rebuild a new server and re-install the software.

Thanks, George
