Can't have enough of it anyways, and as it's dirt cheap these days, why the heck not? I'm certainly planning to go 16GB when I go Ivy.
What I'm saying is this:
1) You have an ESXi host with a Windows VM and a Linux VM. Neither VM can be displayed on the host's screen. The host will only show the host's stripped-down ESXi Linux CLI. The guests can use VT-d or IOMMU, but I don't believe that they can use the GPU to display the guest's screen. If it was possible to do so, you wouldn't be able to switch the display back and forth between VMs. The GPU would be owned by a single guest if it was possible to even show the guest's screen using VT-d or IOMMU.
2) You have a Linux host with a Windows guest. There are no non-bare-metal hypervisors that allow you to utilize VT-d or IOMMU. If all it took was buying a second GPU so that I could give it to the guest, I would be all over it, but it simply isn't possible.
