I followed the IBM tutorial referenced in linux-kvm.org: http://pic.dhe.ibm.com/infocenter/lnxinfo/v3r0m0/index.jsp?topic=/liaai/kvminstall/liaaikvminstallstart.htm The VM is configured with 2GB memory, 1 CPU out of the 4 of the host, config cloned from host (=Sandy Bridge) Network, storage and serial drivers use virtio mode. Network uses the default NAT mode. Storage is my raw /dev/sdb, a disk encrypted by my company's IT with McAfee endpoint encryption (previously named SafeBoot). At VM creation the display is automatically configured by virt-manager in Spice mode with QXL video (64MB). In the working case the graphics view of virt-manager first shows the McAfee end-point encryption login screen (this is pre-Windows) and eventually the normal windows display. Cut/paste work fine, etc... and the performances are good. In the non-working case, the graphic display remains uniformly grey, exactly as when the guest is not started at all. Still virt-manager reports that the machine is running and the power control switch lets me force power-off (mcafee login does not support acpi shutdown command). virt-manager also proposes a serial console, but I think Windows does not use it. If I revert to VNC mode, display works fine (although slowly), I don't have cut/paste functionality and my host is significantly slowed by this workload. I would have liked to post screen shots, but, well, these experiments are for my spare time and I have to work with that Windows machine, so I have now booted directly from this HDD. I have also started re-installing host Linux OS to restart from a fresh F19. This time I will try to install kvm and create the VM with the system already configured in multi-screen mode (need to bring the docking station and a monitor back to home for the test).
