TPM 2.0 module disappears after trying to delete key in VirtualBox #3368
Comments
hi i have the same problem, did i find where it comes from ? |
Not yet. |
Sounds like a VirtualBox problem, rather than our problem. |
I'm having the same problem on my NixOS server and just decided to turn it off altogether. I know that doesn't really solve the issue in your case, did you figure out a solution? |
Debian 12.5 guest under Windows 10 host, VirtualBox 7.0.14
After executing
tpm2_evictcontrol -C o -c 0x81000000
(trying to remove a key) the driver returns:And after that I have to reboot to get the TPM module to respond to anything again. If I try any other command before rebooting I just get a timeout:
ERROR:tcti:src/tss2-tcti/tcti-device.c:503:Tss2_Tcti_Device_Init() timeout waiting for response from fd 3
I receive few kernel messages with the last one going on every 10 sec:
Is this somehow a normal behavior or the virtual TPM module is crashing ?
Thanks.
