[libvirt] [PATCH 00/18] Add support for vTPM state encryption
by Stefan Berger 10 Jul '19

10 Jul '19

This series of patches addresses the RFE in BZ 172830: https://bugzilla.redhat.com/show_bug.cgi?id=1728030 This series of patches adds support for vTPM state encryption by passing the read-end of a pipe's file descriptor to 'swtpm_setup' and 'swtpm' where they can read a passphrase from and derive a key from that passphrase. The TPM's domain XML looks to enable state encryption looks like this: <tpm model='tpm-tis'> <backend type='emulator' version='1.2'> <encryption format='vtpm'> <secret type='passphrase' uuid='2c9ceaba-c6ef-4f38-86fd-6e3adb2df5cd'/> </encryption> </backend> <alias name='tpm0'/> </tpm> The vTPM secret holding the passphrase looks like this: <secret ephemeral='no' private='yes'> <uuid>2c9ceaba-c6ef-4f38-86fd-6e3adb2df5cd</uuid> <description>vTPM passphrase example</description> <usage type='vtpm'> <name>vtpm_example</name> </usage> </secret> The swtpm v0.2 (upcoming) is needed that supports the command line option --print-capabilities returning a JSON object that identifies features added since v0.1. One such features is the possibility to pass a passphrase via a file descriptor. The patches do some refactoring of existing code on the way.

[libvirt] [PATCH v9 00/10] work-in-progress: incremental backup
by Eric Blake 09 Jul '19

09 Jul '19

This is the current state of my incremental backup work on top of the v9 checkpoint patches [1]. While everything compiles and my local tests are able to perform an incremental backup, I already know that the code needs a lot of cleanups before it can be accepted upstream; this is more of a preview post to allow further testing against the APIs while my more immediate focus is on getting checkpoints in. There will be a v10 of this portion of the backup work, but now that checkpoints are nearly ready to go, I'm still aiming to get backups in the same 5.6 release window. [1] https://www.redhat.com/archives/libvir-list/2019-July/msg00236.html I've pushed a tag backup-v9 to both my libvirt.git and libvirt-python.git repos to match: https://repo.or.cz/libvirt/ericb.git/shortlog/refs/tags/backup-v9 https://repo.or.cz/libvirt-python/ericb.git/shortlog/refs/tags/backup-v9 Changes since v8: - lots of rebasing - however, reviews from v8 on this part of the series have not been addressed yet... 001/10:[down] 'backup: qemu: Implement VIR_DOMAIN_CHECKPOINT_XML_SIZE flag' 002/10:[0016] [FC] 'backup: Document new XML for backups' 003/10:[0112] [FC] 'backup: Introduce virDomainBackup APIs' 004/10:[0419] [FC] 'backup: Implement backup APIs for remote driver' 005/10:[0023] [FC] 'backup: Parse and output backup XML' 006/10:[0052] [FC] 'backup: Implement virsh support for backup' 007/10:[0006] [FC] 'backup: qemu: Implement framework for backup job APIs' 008/10:[0010] [FC] 'backup: Wire up qemu full pull backup commands over QMP' 009/10:[----] [-C] 'backup: qemu: Wire up qemu full push backup commands over QMP' 010/10:[down] 'backup: Implement qemu incremental pull backup' Eric Blake (10): backup: qemu: Implement VIR_DOMAIN_CHECKPOINT_XML_SIZE flag backup: Document new XML for backups backup: Introduce virDomainBackup APIs backup: Implement backup APIs for remote driver backup: Parse and output backup XML backup: Implement virsh support for backup backup: qemu: Implement framework for backup job APIs backup: Wire up qemu full pull backup commands over QMP backup: qemu: Wire up qemu full push backup commands over QMP backup: Implement qemu incremental pull backup include/libvirt/libvirt-domain.h | 41 +- src/conf/backup_conf.h | 94 +++ src/conf/virconftypes.h | 3 + src/driver-hypervisor.h | 14 + src/qemu/qemu_blockjob.h | 1 + src/qemu/qemu_domain.h | 4 + src/qemu/qemu_monitor.h | 4 + src/qemu/qemu_monitor_json.h | 3 + docs/docs.html.in | 3 +- docs/format.html.in | 1 + docs/formatbackup.html.in | 184 +++++ docs/formatcheckpoint.html.in | 12 +- docs/index.html.in | 3 +- docs/schemas/domainbackup.rng | 219 ++++++ examples/c/misc/event-test.c | 3 + libvirt.spec.in | 1 + mingw-libvirt.spec.in | 2 + src/conf/Makefile.inc.am | 2 + src/conf/backup_conf.c | 546 ++++++++++++++ src/conf/domain_conf.c | 2 +- src/libvirt-domain-checkpoint.c | 7 +- src/libvirt-domain.c | 219 ++++++ src/libvirt_private.syms | 8 +- src/libvirt_public.syms | 3 + src/qemu/qemu_domain.c | 37 +- src/qemu/qemu_driver.c | 706 ++++++++++++++++++- src/qemu/qemu_monitor.c | 11 + src/qemu/qemu_monitor_json.c | 80 +++ src/qemu/qemu_process.c | 9 + src/remote/remote_driver.c | 3 + src/remote/remote_protocol.x | 53 +- src/remote_protocol-structs | 28 + tests/Makefile.am | 2 + tests/domainbackupxml2xmlin/backup-pull.xml | 9 + tests/domainbackupxml2xmlin/backup-push.xml | 9 + tests/domainbackupxml2xmlin/empty.xml | 1 + tests/domainbackupxml2xmlout/backup-pull.xml | 9 + tests/domainbackupxml2xmlout/backup-push.xml | 9 + tests/domainbackupxml2xmlout/empty.xml | 7 + tests/virschematest.c | 2 + tools/virsh-domain.c | 253 ++++++- tools/virsh.pod | 49 ++ 42 files changed, 2634 insertions(+), 22 deletions(-) create mode 100644 src/conf/backup_conf.h create mode 100644 docs/formatbackup.html.in create mode 100644 docs/schemas/domainbackup.rng create mode 100644 src/conf/backup_conf.c create mode 100644 tests/domainbackupxml2xmlin/backup-pull.xml create mode 100644 tests/domainbackupxml2xmlin/backup-push.xml create mode 100644 tests/domainbackupxml2xmlin/empty.xml create mode 100644 tests/domainbackupxml2xmlout/backup-pull.xml create mode 100644 tests/domainbackupxml2xmlout/backup-push.xml create mode 100644 tests/domainbackupxml2xmlout/empty.xml -- 2.20.1

[libvirt] [PATCH] logging: ensure virtlogd rollover takes priority over logrotate
by Daniel P. Berrangé 09 Jul '19

09 Jul '19

The virtlogd config is set to rollover logs every 2 MB. Normally a logrotate config file is also installed to handle cases where virtlogd is disabled. This is set to rollover weekly with no size constraint. As a result logrotate can interfere with virtlogd's, rolling over files that virtlogd has already taken care of. This changes logrotate configs to rollover based on a max size constraint of 2 MB + 1 byte. When virtlogd is running the log files will never get this large, making logrotate a no-op. If the user changes the size in virtlogd's config to something larger, they are responsible for also changing the logrotate config suitably. The LXC driver doesn't use virtlogd, but its logrotate config is altered to match the QEMU driver logrotate, just for the sake of consistency. Signed-off-by: Daniel P.

[libvirt] [PATCHv2] Do not keep empty log files for deleted domains
by Jan Zerebecki 09 Jul '19

09 Jul '19

With logrotates copytruncate when e.g. domain1 doesn't exist anymore /var/log/libvirt/qemu/domain1.log will still exist after rotation even though it will never be written to. When new domain names keep getting used this leads to a lot of empty logfiles. This may lead to slowdown or lack of free disk space / inodes. Fix this by replacing copytruncate with the apropriate postrotate command to reopen log files. Thus after the apropriate time log files for deleted domains will be gone. This also has the advantage that the chance for loss of a few lines during copytruncate is gone. This only fixes the issue for qemu domains, others still have the same problem unfixed.
