Hello,
I have cooked up a patch of ACPI PCI hotplug controller emulation, which can be
extended to support hotplug of virtual PCI device, say ne2000 NIC.
Are you guys interested to integrate this device emulation?
BTW, modification of ACPI DSDT table is required, but QEMU reuse the binary from
Bochs. I don't know how to handle such issue in QEMU.
Thanks,

Get the changes merged into upstream bochs source.

KVM also has such a feature. It might be a good idea to look at that
implementation and see how things differ between the approaches and
maybe get yours into KVM too.

Best idea here would be to send the patches to the bochs list.
Alternatively there is a diff file against the bochs bios in the qemu
svn too. Getting things upstream with bochs is preferred though.

This diff file seems to be used to keep pending changes for reference only.
It's better to push everything into Bochs. But you know, bochs is written in
C++, so we have to rewrite device emulation:(

Tosatti,
I know you have a hotplug patch for KVM.
Do you have any plan to push it into QEMU upstream?
To do this, also need push the DSDT changes into Bochs.
Maybe we can co-ordinate to eliminate duplicated efforts.
