I've checked that the swtpm style is still working: The following does not expose new-issues due to the upgrade: $ qemu-system-x86_64 -display none -accel kvm -m 1024 -chardev socket,id=chrtpm,path=/tmp/mytpm1/swtpm-sock -tpmdev emulator,id=tpm0,chardev=chrtpm -device tpm-tis,tpmdev=tpm0
But I have OTOH failed to verify the positive effect. The command working in later releases like: $ lxc config device add f tpm tpm path=/dev/tpm0 # Then in the container $ sudo qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -tpmdev passthrough,id=tpm0,path=/dev/tpm0 -device tpm-tis,tpmdev=tpm0 Keeps failing for me on the backports for Focal/Groovy. I have double checked if the build really contains the changes we have tested successfully from the PPA and it seems it does. But then my setup was never super-great emulating much of what should be real. @Andre - If you could give the builds in -proposed a try just as you did in comment #14 / #15 that would be great and very helpful! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1903864 Title: qemu-system-x86_64: -device tpm-tis,tpmdev=tpm-tpm0,id=tpm0: Property 'tpm-tis.tpmdev' can't find value 'tpm-tpm0' To manage notifications about this bug go to: https://bugs.launchpad.net/launchpad/+bug/1903864/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
