Hi,
This series brings libvirt the x86 TDX support.
* What's TDX? TDX stands for Trust Domain Extensions which isolates VMs from the virtual-machine manager (VMM)/hypervisor and any other software on the platform.
This patchset extends libvirt to support TDX, with which one can start a TDX guest from high level rather than running qemu directly.
* Misc As QEMU use a software emulated way to reset guest which isn't supported by TDX guest for security reason. We simulate reboot for TDX guest by kill and create a new one in FakeReboot framework.
Complete code can be found at [1].
* Test Tested with upstream qemu v10.0.0-1724-gf9a3def17b shutdown/reboot/reset with virsh shutdown/reboot trigger in guest shutdown with on_poweroff=destroy/restart reboot with on_reboot=destroy/restart
FYI when I have a guest crash libvirt logs error : qemuMonitorJSONGuestPanicExtractInfo:638 : internal error: unknown panic info type 'tdx' this is a new type of panic data structure from upstream QEMU that libvirt needs to handle in some way With regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
