[PVE-User] Stability problems in PVE 1.1?

[Theron T. Trout]

I wanted to follow up on this topic to provide a bit of closure for
anyone following this thread.

We installed the latest AMD CPU drivers for Windows 2003 and all but one
of the machines started running reliably.  The problematic virtual
machine still has some problems but these improved after applying a few
Proxmox patches and restarting the Proxmox server (required after a pve
kernel patch).  A few issues remain, but we think this is the result of
some problem with the Windows 2003 install and not related to Proxmox
VE/KVM.
