Description Qinghua Cheng 2022-09-28 09:06:27 UTC 
This bug was initially created as a copy of Bug #1877721

I am copying this bug because: 

This bug is still reproducible on rhel 9.2, with fresh installed windows 10 guest.


Description of problem:
Bitlocker doesn't start to do encryption with fresh installed Win10 guest. But a reboot of the guest, bitlocker can start encryption. 

Version-Release number of selected component (if applicable):
RHEL 8.3 
Kernel: 4.18.0-234.el8.x86_64
qemu-kvm: qemu-kvm-5.1.0-2.module+el8.3.0+7652+b30e6901.x86_64
edk2: edk2-ovmf-20200602gitca407c7246bf-3.el8.noarch
libptms: libtpms-0.7.2-1.20200527git7325acb477.module+el8.3.0+7068+4e1b8df5.x86_64
swtpm: swtpm-0.3.0-1.20200218git74ae43b.module+el8.3.0+7648+42900458.x86_64

How reproducible:


Steps to Reproduce:
1. Install a win10 guest (q35 + OVMF)
2. Attach vtpm device to win10 guest
3. Inside guest vm run commands:

bdehdcfg -target c: shrink -newdriveletter s: -size 606 -quiet
manage-bde -on c:

reboot system as required. 

4. Re-login guest vm after reboot, run command: 
manage-bde -status

Actual results:
Encryption is not started
Pop up dialog with Bitlocker could not be enabled. (see attachment)

BitLocker Drive Encryption: Configuration Tool version 10.0.19041
Copyright (C) 2013 Microsoft Corporation. All rights reserved.

manage-bde -status

Disk volumes that can be protected with
BitLocker Drive Encryption:
Volume C: [Windows]
[OS Volume]

    Size:                 29.62 GB
    BitLocker Version:    None
    Conversion Status:    Fully Decrypted
    Percentage Encrypted: 0.0%
    Encryption Method:    None
    Protection Status:    Protection Off
    Lock Status:          Unlocked
    Identification Field: None
    Key Protectors:       None Found

Expected results:

Bitlocker can encrypt win10 guest without issue.

Additional info:

This issue only happens with refresh installed win10 guest. When reboot the guest vm again, and repeat the test steps, bitlocker can start disk encryption.

In https://bugzilla.redhat.com/show_bug.cgi?id=1877721#c7, you tested successfully with a more recent version of libtpms & swtpm.

Have you checked with latest rhel9 build? (I think they are libtpms-0.9.1-2.20211126git1ff6fe1f43.el9 & swtpm-0.7.0-3.20211109gitb79fd91.el9)

In any case, my remarks/questions in Bug #1877721 are still valid, I am not sure this is a vtpm issue.

thanks
Comment 2 Qinghua Cheng 2022-09-29 10:05:36 UTC 
Hi Marc-Andre,

I just tested on rhel 9.2 with Win11(22h2) guest:

libtpms-0.9.1-2.20211126git1ff6fe1f43.el9.x86_64
swtpm-0.7.0-3.20211109gitb79fd91.el9.x86_64
kernel: 5.14.0-168.el9.x86_64
qemu-kvm: qemu-kvm-7.1.0-1.el9.x86_64

Win11 guest can also reproduce this issue. 

Thanks.

Marek - any chance we can get someone from the Virt Windows SST to weigh in on this case? It's odd the 2nd reboot "fixes" things magically. 

Maybe even a direct connect with Microsoft?  Are there any debugging tools that could be employed to rule out QEMU / libptms / swtpm?

thanks
