Hello PVE Team,<br>
<br>
is it possible to migrate a Windows 2012 Server from a clusternode
with Proxmox 3.3 running and a valid community licence to a
temporary standalone server with the unsupported (testing) Proxmox
3.1.<br>
<br>
I'm experiencing network problems with the cluster and want to
investigate, while the virtual machines should run at a fallback
server. I want to look into the problems with as few downtime as
possible and don't have to do it in a hurry either.<br>
<br>
However, Windows won't start correct, that is, not at all with
rebooting short after starting to load. This might possibly (my
guess) be due to "hardware" changes in the VM. The real hardware, a
DELL R720, is identical to the ones in the cluster.<br>
I don't want to alter the VM or resolving it within the Windows
recovery environment. It simply should run at the other Server and
eventually go back in the cluster without it even recognize the
change.<br>
<br>
The greatest difference in the versions I see is the pve-qemu-kvm
(the VMs are KVM virtualised) which is version 1.4-17 on the
pve-test machine and 2.1-5 on the stable.<br>
<br>
Is it because of this discrepancy that my VMs won't recognize the
virtualised hardware as their original or are there other problems.
I had so far almost no problems migrating VMs to other versions of
the Proxmox VE. However, I think, that were linux machines.<br>
<br>
Would it help to upgrade the System to stable (buying a licence) or
would I get the same errors again?<br>
<br>
PS: the network problems which I'm unable to pin so far (it didn't
occur again, too):<br>
