Re: [Xen-users] [SOLVED] vTPM problem

[Andreas Sommer <AndiDog@xxxxxx>]

We found a solution that should work: The steps to get vTPM working on 
Xen-3.5-unstable are
- Follow the steps on http://cybione.org/~cdidier/blog/200812020841.html
- Make sure vtpm_managerd is started on the host (dom0) before starting 
any guests that need vTPM
- On linux guests, make sure that /dev/tpm is created. If not, add the 
command "mknod /dev/tpm c 10 224" to your autostart (e.g. rc.local)
Sorry but we did not try vTPM with full virtualization, only with 
paravirtualized linux guests.
mknod /dev/tpm c 10 224

Hopefully somebody will find this description helpful :)

Best regards
Andreas
