What i5 do you have and you are using iommu=soft swiotlb=force vt.handoff=7 does your system supports
vt-d ?
So on a linux DomU I had iommu=soft and swiotlb=force, but what are the other one/two commands, your typos are hard for me to read there.
So far as the proc I have,
i5-2400 CPU @ 3.10GHz
flags : fpu de tsc msr pae mce cx8 apic sep mtrr mca cmov pat clflush acpi mmx fxsr sse sse2 ss ht nx constant_tsc nonstop_tsc aperfmperf pni pclmulqdq
vmx est ssse3 sse4_1 sse4_2 x2apic popcnt aes hypervisor ida arat tpr_shadow vnmi flexpriority ept vpid
http://ark.intel.com/products/52207/Intel-Core-i5-2400-Processor-6M-Cache-up-to-3_40-GHz
According to Intel, I have both VT-d and VT-x (w/EPT). This proc should be sufficient. Iâve installed XenServer and it didnât bark (and it will) about insufficient
VT flags.

I tried disabling and also uninstalling the Standard VGA Adapter. It doesn't appear to be using the display headers on the HD6450 at all. Since these settings cannot be changed via remote desktop, I installed RealVNC... which seems to bork

Anyone else having an issue with their gpu passthrough not using the card's display headers at all? This is a HVM Windows 7 x64 box.

Did you adjust your display settings to switch the default desktop screen to the one on the Radeon?
