VB7 Oct 10 release: TPM errors Win 10 and 11 guests

Post by randymca »

Once TPM 2.0 enabled for win 10 guest there were repeating TPM event 15 's, 6 at a time randomly spaced in event log though elapsed time divisible by 15 minutes - so 4+ groups of 6 events
occurring every 24 hours, upgraded VM to win 11 - there are (so far) two TPM event's occurring around 4am on multiple win guests.

VB7 7.0.0-153978 Oct 10th release ( inplace upgrade on top of 6.1.32-149290 )
Host: Win 11 21H2 Build 22000.978
VM's: Win 11 22H2 build 22621.674

checks inside a VM
- device manager says TPM 2.0 is ok
- tpm.msc says device is ready
- windows 11 upgrade checker (when windows 10) said TPM ok
- Windows Security (systray)->Device security->Security processor shows:
Attestation Not Supported
Storage Ready
- Windows Security->Device security->Security processor->Troubleshooting displays error "Can't get TPM information. Contact your device manufacturer."

in VM, TPM feature shows "Attestation Not Supported" which is to do with certificate authority (CA) functionality, my intel hosts with Intel TPM 2.0 show "Attestation Ready"
is "Attestation Not Supported" an issue or expected in VM ? , could something trying to use this functionality be causing these events ?


EVENT DETAILS
