I am trying to install Windows 7 on Proxmox Virtual Environment version 4.2-4/2660193c, running on Debian Jessie. I have followed the instructions on this site.
I uploaded a known-good Win7 ISO (that works fine with VirtualBox and real hardware) to Proxmox, and configured VM following the recommended best practices.
When the VM is started, Windows shows the gray text mode progress bar saying "Windows is loading files ...", then switches to "Starting Windows" and stays there for hours.
There is no visible action, no colored Windows logo, no animation, no disk I/O, no CPU load, no log output. No way to continue.
XP Home installed without any problems in a VM.
Host is Intel Core i5, VT enabled, 32 GByte RAM, 8 TByte SATA disks.
How do I get Win7 to continue its setup process on Proxmox 4.2?
