Hi,

I have just compiled and installed Xen 4.4-unstable changeset 27262
and Linux kernel 3.11.0-rc1. My Windows 7 Ultimate HVM domU
configuration file is as attached.

I tried to passthrough the onboard Intel HD Graphics 4600 IGD to
Windows 7 Ultimate HVM domU.

<snip>

device_model_version="qemu-xen-traditional"
name="Windows7"
builder="hvm"
vcpus=4
memory=2048

There was another report that >= 2GB of RAM with GPU passthru doesn't work,
so please try with 1GB of RAM for the HVM guest.

Also I think there is another PCI passthru related issue in Xen 4.4 at the 
moment,
so you probably should try using Xen 4.3.0 or wait for a couple of weeks for 
the 4.4 issue to get sorted out.

Dear Pasi,

I am still using Xen 4.4-unstable. I have tried memory=1024 for both Windows 8 and Windows 8.1 HVM domU but both of them couldn't start. I have also tried memory=1024 for Windows 7 HVM, and although it could start, I still get error code 43 and 16 colors on the monitor only.

I have tried Xen 4.3.0 as well but with Windows 7 HVM domU, I still get error code 43 and 16 colors on the monitor.

Please advise.

Thank you very much.
