Re: [libvirt] [RFC PATCH v3 0/4] Improve Ceph Qemu+RBD support

The current support for qemu and Ceph RBD (rados block device) has two main deficiencies: authentication doesn't work, and it relies on environment variables (which don't work with latest upstream). This patch set addresses both those problems. The first two patches update the xml schemas and conf to add a Ceph secret type and to specify authentication information along with the rbd disk. The next patch passes virConnectPtr into the Domain{Attach,Detach} methods (needed to access secrets while building the qemu command). The final patch replaces the current RBD qemu code and uses the new conf info to do authentication properly. We still need to make a change there to avoid having the authentication key show up on qemu command line (there are a few ways to do this, which will be discussed in a separate email). Changes from v2: make <auth> a direct child of <disk> instead of <source> allow secret lookup by UUID or usage test with fake secret driver other fixes from Daniel's review Changes from v1: update docs/schemas/{domain,secret}.rng Josh Durgin (1): storage: add auth to virDomainDiskDef Sage Weil (3): secret: add Ceph secret type qemu: pass virConnectPtr into Domain{Attach,Detach}* qemu/rbd: improve rbd device specification docs/schemas/domaincommon.rng | 29 ++ docs/schemas/secret.rng | 10 + include/libvirt/libvirt.h.in | 3 + src/Makefile.am | 3 +- src/conf/domain_conf.c | 105 +++++++- src/conf/domain_conf.h | 17 ++ src/conf/secret_conf.c | 23 ++- src/conf/secret_conf.h | 1 + src/qemu/qemu_command.c | 289 ++++++++++++-------- src/qemu/qemu_command.h | 3 +- src/qemu/qemu_driver.c | 17 +- src/qemu/qemu_hotplug.c | 15 +- src/qemu/qemu_hotplug.h | 9 +- src/secret/secret_driver.c | 8 + .../qemuxml2argv-disk-drive-network-rbd-auth.args | 6 + .../qemuxml2argv-disk-drive-network-rbd-auth.xml | 37 +++ .../qemuxml2argv-disk-drive-network-rbd.args | 6 +- tests/qemuxml2argvtest.c | 52 ++++ 18 files changed, 485 insertions(+), 148 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-drive-network-rbd-auth.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-drive-network-rbd-auth.xml -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
