Makes Windows 11 (test build) happy: https://i.imgur.com/kZ0Mpnr.jpeg
Tested under Linux as well, works with (updated) OVMF and SeaBIOS, though SeaBIOS requires clearing via the BIOS setup screen and may not support all features it seems (e.g. Windows shows the TPM, but doesn't allow BitLocker, presumably because it requires UEFI). Requires swtpm and libtpms: https://github.com/stefanberger/swtpm (stable-0.6) https://github.com/stefanberger/libtpms (stable-0.8) Both repos allow debian builds, that's what I used for testing. Decided to send a WIP version before leaving on vacation, so you can take your time with feedback :) Design decision: 'swtpm' requires a *directory* per VM to store data, the files themselves are rather small (8.5kB for an initialized TPM 2.0 w/ BitLocker enabled). To allow for easier HA I went with a path in '/etc/pve/priv' for now, but that comes with it's own drawbacks. For example, a guest may write TPM state as often as they like, and Windows seems to do so every few seconds at random. (note: swtpm writes a temporary file and then uses atomic replace) Other ideas for this: * store in regular path, e.g. '/var/lib' - how to do HA? (note that live-migration works regardless, since the state is transferred via QEMU) * treat like efidisk and allow any storage - would be my favourite, but as said, swtpm requires a directory, not a single file... Missing feature/known issues: * backups and offline-snapshots don't include TPM data * migration may hickup, since destination and target are effectively "the same" * needs improved clearing logic, or potentially none at all (would be a benefit for the "efidisk-like" variant) edk2-firmware: Stefan Reiter (1): enable TPM and TPM2 support debian/rules | 4 ++++ 1 file changed, 4 insertions(+) qemu-server: Stefan Reiter (1): fix #3075: add TPM v1.2 and v2.0 support via swtpm PVE/QemuServer.pm | 134 +++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 133 insertions(+), 1 deletion(-) -- 2.30.2 _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
