QEMU has TPM device emulation, but the backend for the emulation must be a real TPM in the host. As such only a single guest can have a virtual TPM on each host. This basically it essentially useless as a feature for the cloud. There was work to allow the virtual TPM to be backed by a custom data store, so that all guests on a host could have this functionality, but it was never merged upstream in QEMU Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
