We are getting close to the next release of libvirt. To aim for the release on Nov 01 I suggest entering the freeze on Friday Oct 28 and tagging RC2 on Tuesday Oct 25. I hope this works for everyone. Jirka

[PATCH v2 0/9] qemu: tpm: Add support for migration across shared storage
by Stefan Berger 18 Oct '22

18 Oct '22

This series of patches adds support for migrating vTPMs across hosts whose storage has been set up to share the directory structure holding the state of the TPM (swtpm). A new migration flag VIR_MIGRATE_TPM_SHARED_STORAGE is added to enable this. This flag influences the management of the directory structure holding the TPM state, which for example is only removed when a domain is undefined and not when a VM is removed on the migration source host. Further, when shared storage is used then security labeling on the destination side is skipped assuming that the labeling was already done on the source side. I have tested this with an NFS setup where I had to turn SELinux off on the hosts since the SELinux MLS range labeling is not supported by NFS. Shared storage migration requires (upcoming) swtpm v0.8. Stefan Stefan Berger (9): util: Add parsing support for swtpm's cmdarg-migration capability qemu: Introduced VIR_MIGRATE_TPM_SHARED_STORAGE for TPM migration qemu: tpm: Conditionally create storage on incoming migration qemu: tpm: Pass --migration option to swtpm if supported qemu: tpm: Avoid security labels on incoming migration with shared storage qemu: tpm: Require UNDEFINE_TPM to be set to remove TPM state qemu: tpm: Determine whether to remove TPM state during migration qemu: tpm: Enable migration with VIR_MIGRATE_TPM_SHARED_STORAGE virsh: Add support for --tpm-shared-storage flag for migration docs/manpages/virsh.rst | 6 +++ include/libvirt/libvirt-domain.h | 8 +++ src/conf/domain_conf.h | 1 + src/qemu/qemu_driver.c | 4 +- src/qemu/qemu_extdevice.c | 5 +- src/qemu/qemu_extdevice.h | 3 +- src/qemu/qemu_migration.c | 23 +++++++-- src/qemu/qemu_migration.h | 1 + src/qemu/qemu_process.c | 10 ++-- src/qemu/qemu_process.h | 6 ++- src/qemu/qemu_saveimage.c | 2 +- src/qemu/qemu_snapshot.c | 4 +- src/qemu/qemu_tpm.c | 87 ++++++++++++++++++++++++++++---- src/qemu/qemu_tpm.h | 24 ++++++++- src/util/virtpm.c | 1 + src/util/virtpm.h | 1 + tools/virsh-domain.c | 7 +++ 17 files changed, 164 insertions(+), 29 deletions(-) -- 2.37.3

[PATCH 00/15] schema: Fix forgotten interleaving of elements (part 1)
by Peter Krempa 17 Oct '22

17 Oct '22

Context: https://listman.redhat.com/archives/libvir-list/2022-October/234860.html This series fixes the trivial/straightforward cases found by using Daniel's "fuzzing" script. Note that you have to exclude '-invalid.xml' files and all output-only XMLs (domaincaps, capabilities). Best viewed with 'git show -w'. There's 7 more pathces needed to fix the schema to work with the above mentioned script but they have more complex interactions and I'll need to re-consider them.
