Hi there, Is there a way to prevent Windows HVM guests from seeing passed through devices like graphics cards as being ejectable? i.e. you pass through a graphics adapter to an HVM guest which happens to be Windows. Windows sees this as a device with hotplug capability.
Therefore it shows up in "safely remove hardware" option in the windows system tray. VMWare provides an option to turn that off.
I don't seem an option of this in Xen 4.2 yet. How can I override this behavior in Xen? I tried commenting out the following in: tools/ioemu-qemu-xen/hw$ vi pass-through.c
/* SHPC Capability List Item reg group */ { .grp_id = PCI_CAP_ID_HOTPLUG, .grp_type = GRP_TYPE_HARDWIRED, .grp_size = 0x08,
.size_init = pt_reg_grp_size_init, }, but that didn't seem to do it. Matt
