Hi all!
Just setting up a cluster using Centos 7
We have a desperate need for TPM support and:
1. Tried the "standard" distro install. linvirt supports
TPM passthrough but kvm-qemu barfs:
"unsupported configuration: The QEMU executable /usr/libexec/qemu-kvm does not support TPM backend type passthrough"
2. The activated the qemu-ev repo and updated qemu-kvm to version 2.10.0, which for sure
should support at least passthrough. No luck - Same error message.
Downloaded the source for th rpm and found a line: "--disable-tpm"
in build_configure.sh. Guess that the maintainers has some reason
to turn tpm off. Can somone confirm this?
Not sure about reasons for turning off, but request to enable it has been closed wontfix: https://bugzilla.redhat.com/show_bug.cgi?id=1327947
3. And now what next? The setup would really need swtpm, which
should be available in 2.11.0. Can someone confirm that tpm
will be enabled here? Would also be nice having a libvirt that
will accept the swtpm configuration. the current don't like it.
Adding Miroslav
Could of course recompile qemu myself, but really wouldn't like
going that route. The sheer number of patches applied is quite scary...
Best
Dag
