swtpm at /usr/bin/swtpm does not support TPM 2

Running 7.2-11. I recently updated and rebooted the server. Now, any VM with a TPM will not start and shows and exit code of 1. When running the command in question (swtpm_setup --tpmstate file:///dev/HDD-500GB-thin/vm-104-disk-2 --createek --create-ek-cert --create-platform-cert --lock-nvram --config /etc/swtpm_setup.conf --runas 0 --not-overwrite --tpm2 --ecc) from the terminal I get "swtpm at /usr/bin/swtpm does not support TPM 2" Any troubleshooting tips are greatly appreciated.

I have also discovered that when running swtpm I get the following: "swtpm: error while loading shared libraries: libtpms.so.0: failed to map segment from shared object"

Also seeing this in the syslog: apparmor="DENIED" operation="file_mmap" profile="swtpm" name="/usr/local/lib/libtpms.so.0.10.0" pid=46073 comm="swtpm" requested_mask="m" denied_mask="m" fsuid=0 ouid=0

I wish I had a good explanation, but I noticed there were several obsolete packages/kernels so I ran "apt-get autoremove". Rebooted and everything is working now. :confused:
 
I am getting the same syslog messages as well. Update and package cleanup/reboot did not resolve the issue for me.
 
Not a great fix but a workaround until this is resolved is to set the apparmor policy to complain for the swtpm.

apt install apparmor-utils
aa-complain /usr/bin/swtpm

please post the output of pveversion -v and qm config <ID>, replacing <ID> with the ID of an affected VM.
 
/usr/local/lib/libtpms.so.0.10.0 is not part of any Debian Bullseye or PVE package.. you must have installed third party software and/or packages?
 
Syslog Error: (I allowed this in apparmor with aa-complain)

I'm also having the exact same issue. Seems to be related to this bug: https://bugs.launchpad.net/ubuntu/+source/swtpm/+bug/1989100

I tried adding /run/libvirt/qemu/swtpm/*.pid rwk, to /etc/apparmor.d/local/usr.bin.swtpm as mentioned in the bug report but that didn't seem to fix the issue for me. Not sure if the /run/libvirt/qemu directory is the correct path.

Setting the apparmor policy to complain fixed the issue for me.

There's also this submitted issue: https://github.com/stefanberger/swtpm/issues/770

the apparmor messages are totally different though ;) could you provide the following:

Code: 
dpkg --list | grep tpm
ls -lha /usr/local/lib/libtpm*
ldd /usr/bin/swtpm

thanks!

could you also run dpkg -S /usr/local/lib/libtpm*?
 
please describe you symptoms and include relevant config files/logs/error messages as well as "pveversion -v" output..

The error does not seem to only happen on a specific pve- version. I've upgraded to the latest release on saturday.
And found, that the package libtpms was only installed on the one of my cluster nodes where starting a vm with a tpm2 state disk didn't work.

The only difference was the libtpms. so I removed this package and voila... the vm's using tpm2 disk are starting.

so I think the libtpms package causes the problem.

I am still not sure where you got that package from.. are you all on some hoster and using their images that comes/came with it preinstalled maybe?

I think I've tried it when Windows 11 was new and not supported by Proxmox. (I think it was pre 7.0 Proxmox release).
I'm not really sure where I got this from.
