Can't rollback snapshot, vm with tpm feature

[sssakuya]

Hi, all.

I tried to rollback snapshot today but meet this issue. shell shows me:

kvm: Unknown ramblock "tpm-ppi", cannot accept migration
kvm: error while loading state for instance 0x0 of device 'ram'
kvm: Error while loading VM state: Invalid argument

I wonder maybe tpm state caused this issue.

Sincerely,

could you post the output of 'pveversion -v' and the full contents of the VM config file (/etc/pve/local/qemu/XXX.conf)?
