[PATCH] Use G_N_ELEMENTS() more
by Michal Privoznik 13 Mar '23

13 Mar '23

In a few places we still use the good old: sizeof(var) / sizeof(var[0]) sizeof(var) / sizeof(int) The G_N_ELEMENTS() macro is preferred though. In a few places we don't link with glib, so provide the macro definition.

[PATCH v1 0/3] qemu: add luks-any encryption support for RBD images
by Or Ozeri 13 Mar '23

13 Mar '23

Starting from Ceph 0f93f745 (unreleased 18.0.0) and qemu b8f218ef (unreleased 8.0.0), qemu and librbd users can use a wildcard format ("luks-any" in qemu, "luks" in librbd). This format can be used to parse the image as either LUKS or LUKS2, auto-detecting the actual format from the on-disk header. This patch series enables libvirt users to use this wildcard format as well (for RBD images only, of course). I manually patched the qemu 8.0.0 replies file to reflect relevant qemu support, to allow my tests to run. Note that any build qemu will not support this feature, unless compiled while having a librbd that has this feature bundled.

[PATCH v1 0/7] qemu: add support for librbd layered encryption
by Or Ozeri 13 Mar '23

13 Mar '23

Starting from Ceph 0f93f745 (unreleased 18.0.0) and qemu 0f385a24 (unreleased 8.0.0), qemu and librbd users can use encrypted RBD cloned images, where the parent image is encrypted using a different scheme (e.g. different passphrase). Opening such image require supplying of multiple secrets. This patch series allows libvirt users to supply multiple secrets necessary for using such RBD images. For example: <encryption format='luks' engine='librbd'> <secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccc2f80fb0'/> <secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccc2f80d6f'/> </encryption> Note that unlike the qemu and libvirt API, we don't allow the user to specify the format of the parent image, but just the passphrase. We do so to minimize the changes made in libvirt. To still be able to support RBD images where the parent is encrypted using a different format (e.g. LUKS2 cloned image of a LUKS parent), an additional patch series allowing for LUKS* (luks-any) format will be submitted. In high-level, this patch series does the following: - change the qemuBlockStorageSourceAttachData struct to support multiple secrets - change the qemuDomainStorageSourcePrivate struct to support multiple secrets - translate multiple secrets from virStorageEncryption to qemu private data I manually patched the qemu 8.0.0 replies file to reflect relevant qemu support, to allow my tests to run. Note that any build qemu will not support this feature, unless compiled while having a librbd that has this feature bundled.

[PATCH] qemuAppendLoadparmMachineParm: add loadparm from hostdev
by Eric Farman 10 Mar '23

10 Mar '23

Commit 54fa1b44afc ("conf: Add loadparm boot option for a boot device") added the ability to specify a loadparm parameter on a <boot/> tag, while commit 29ba41c2d40 ("qemu: Add loadparm to qemu command line string") added that value to the QEMU "-machine" command line parameters. Unfortunately, the latter commit only looked at disks and network devices for boot information, even though anything with VIR_DOMAIN_DEF_FORMAT_ALLOW_BOOT could potentially have this tag. In practice, a <hostdev> tag pointing to a passthrough (SCSI or DASD) disk device can be used in this way, which means the loadparm is accepted, but not given to QEMU. Correct this, and add some XML/argv tests.
