This is the 4th part to implement NPIV migration support [1]. Part 1 and part 2 are pushed. Part 3 (v3: pending for review): https://www.redhat.com/archives/libvir-list/2013-March/msg01440.html ====== This introduces new XMLs to specify the disk source with storage like <disk type='volume' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source pool="$pool_name" volume='$vol_name'/> <seclabel relabel='no'/> </source> <target dev='vdb' bus='virtio'/> </disk> And before domain starting, and disk attaching/updating, the source represented by storage is translated into the real underlying storage volume. Future work: * Support network volume * Support disk backing chain? v1 - v2: * Invoke storage APIs to translate the source directly in qemu driver * 1/8 in v1 is pushed. * 2/8 in v1 is splitted (the code refactoring now is a standalone patch) * Support shared disk for volume type disk * Support sgio setting for volume type disk * No network volume support in v2 RFC - v1: * The XMLs are more simpler - only using pool name and volume name to specify disk source. * Support network pool (rbd, and sheepdog) * Support startupPolicy for volume type disk * Support seclabels for volume type disk * Fix bugs on disk source formating Osier Yang (8): conf: New helper virDomainDiskSourceDefFormat to format the disk source Introduce new XMLs to specify disk source using libvirt storage qemu: Translate the pool disk source when building drive string Support startupPolicy for 'volume' disk Support seclabels for volume type disk qemu: Translate the pool disk source earlier qemu: Support shareable volume type disk qemu: Support sgio setting for volume type disk docs/formatdomain.html.in | 28 ++- docs/schemas/domaincommon.rng | 24 ++ src/conf/domain_conf.c | 274 ++++++++++++++------- src/conf/domain_conf.h | 10 + src/qemu/qemu_command.c | 32 +++ src/qemu/qemu_command.h | 1 - src/qemu/qemu_conf.c | 68 ++++- src/qemu/qemu_conf.h | 3 + src/qemu/qemu_domain.c | 4 +- src/qemu/qemu_driver.c | 16 +- src/qemu/qemu_process.c | 14 +- .../qemuxml2argv-disk-source-pool.xml | 37 +++ tests/qemuxml2xmltest.c | 1 + 13 files changed, 406 insertions(+), 106 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-source-pool.xml -- 1.8.1.4 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
