[libvirt] [PATCH v2 0/4]Add startupPolicy attribute support for hard disks
v1 to v2: added relax schema for disk of block and dir type removed original patch 3/5. The set of patches is trying to add 'startupPolicy' attribute support to the source element of hard disks. Policy levels are using the mandatory, requisite, optional levels as originally documented. For the 'optional' policy, there is a little difference from CDROM and Floppy which only drop its source path, for disks, if missing, the checking function will drop their definitions, because qemu doesn't allow missing source path for hard disk. If guest is using per-device boot element for its devices, after dropping one or more bootable device, the boot order will not be contiguous, the way here I use is to reorder them to make them contiguous. In this way, I introduce two new bit-operating functions virBitmapNextLastSetBit: Search for the last set bit before certain position. virBitmapNextLastClearBit: Search for the last clear bit before certain position.

With 'optional' startupPolicy set, when one or more disk are missing, the qemu process drops their definitions and bootups the vm. When the vm is using per-device boot elements, then we need to reorder them in order to perform migrate successfully if necessary. During the reordering, it uses virBitmapNextLastSetBit to find the last set bit. --- src/conf/domain_conf.c | 2 ++ src/conf/domain_conf.h | 1 + src/qemu/qemu_domain.c | 90 ++++++++++++++++++++++++++++++++++++++++++++++---- 3 files changed, 86 insertions(+), 7 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 177faaa..069e702 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -10992,6 +10992,8 @@ virDomainDefParseXML(virCapsPtr caps, if (virDomainDefAddImplicitControllers(def) < 0) goto error; + /* Save the valid number of per-device boot */ + def->os.nBootPerDevs = bootMapSize; virBitmapFree(bootMap); return def; diff --git a/src/conf/domain_conf.h b/src/conf/domain_conf.h index 96f11ba..362f645 100644 --- a/src/conf/domain_conf.h +++ b/src/conf/domain_conf.h @@ -1543,6 +1543,7 @@ struct _virDomainOSDef { char *machine; size_t nBootDevs; int bootDevs[VIR_DOMAIN_BOOT_LAST]; + unsigned long nBootPerDevs; /* enum virDomainBootMenu */ int bootmenu; char *init; diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index c79b05d..4594b2c 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -1791,30 +1791,89 @@ cleanup: virObjectUnref(cfg); } +/* Reorder devices with per-device boot, make them contiguous */ +static int +qemuDomainPerDevicesBootReorder(virDomainDefPtr def, + virBitmapPtr bitmap) +{ + size_t count; + size_t n; + int i = -1; + + if (bitmap == NULL) + return 0; + + count = virBitmapCountBits(bitmap); + + while (count && count--) { + i = virBitmapNextLastSetBit(bitmap, i); + for (n = 0 ; n < def->ndisks ; n++) { + virDomainDiskDefPtr disk = def->disks[n]; + if (disk->info.bootIndex > i + 1) + disk->info.bootIndex -= 1; + } + + for (n = 0 ; n < def->nnets ; n++) { + virDomainNetDefPtr net = def->nets[n]; + if (net->info.bootIndex > i + 1) + net->info.bootIndex -= 1; + } + + for (n = 0 ; n < def->nhostdevs ; n++) { + virDomainHostdevDefPtr hostdev = def->hostdevs[n]; + if (hostdev->info->bootIndex > i + 1) + hostdev->info->bootIndex -= 1; + } + + for (n = 0 ; n < def->nredirdevs ; n++) { + virDomainRedirdevDefPtr redirdev = def->redirdevs[n]; + if (redirdev->info.bootIndex > i + 1) + redirdev->info.bootIndex -= 1; + } + } + + return 0; +} + int qemuDomainCheckDiskPresence(virQEMUDriverPtr driver, virDomainObjPtr vm, bool cold_boot) { int ret = -1; - int i; + size_t i; virDomainDiskDefPtr disk; char uuid[VIR_UUID_STRING_BUFLEN]; virDomainEventPtr event = NULL; + virDomainDefPtr def = vm->def; + size_t count = def->ndisks; + unsigned long bootMapSize = def->os.nBootPerDevs; + size_t nextDisk = 0; virQEMUDriverConfigPtr cfg = virQEMUDriverGetConfig(driver); + virBitmapPtr bitmap = NULL; + + virUUIDFormat(def->uuid, uuid); - virUUIDFormat(vm->def->uuid, uuid); + if (bootMapSize) { + if (!(bitmap = virBitmapNew(bootMapSize))) { + virReportOOMError(); + goto cleanup; + } + } - for (i = 0; i < vm->def->ndisks; i++) { - disk = vm->def->disks[i]; + for (i = 0; i < count; i++) { + disk = def->disks[nextDisk]; - if (!disk->startupPolicy || !disk->src) + if (!disk->startupPolicy || !disk->src) { + nextDisk++; continue; + } if (virFileAccessibleAs(disk->src, F_OK, cfg->user, cfg->group) >= 0) { /* disk accessible */ + nextDisk++; continue; } @@ -1846,20 +1905,37 @@ qemuDomainCheckDiskPresence(virQEMUDriverPtr driver, VIR_DEBUG("Dropping disk '%s' on domain '%s' (UUID '%s') " "due to inaccessible source '%s'", - disk->dst, vm->def->name, uuid, disk->src); + disk->dst, def->name, uuid, disk->src); event = virDomainEventDiskChangeNewFromObj(vm, disk->src, NULL, disk->info.alias, VIR_DOMAIN_EVENT_DISK_CHANGE_MISSING_ON_START); if (event) qemuDomainEventQueue(driver, event); - VIR_FREE(disk->src); + /* For CDROM and Floppy disk, only drop source path. + * For Hard disk, drop its definition. + */ + if (disk->device == VIR_DOMAIN_DISK_DEVICE_CDROM || + disk->device == VIR_DOMAIN_DISK_DEVICE_FLOPPY) { + VIR_FREE(disk->src); + nextDisk++; + } else { + if (bitmap && disk->info.bootIndex) + ignore_value(virBitmapSetBit(bitmap, disk->info.bootIndex - 1)); + + virDomainDiskDefFree(disk); + if (VIR_DELETE_ELEMENT(def->disks, nextDisk, def->ndisks) < 0) + goto cleanup; + } } + qemuDomainPerDevicesBootReorder(def, bitmap); + ret = 0; cleanup: virObjectUnref(cfg); + virBitmapFree(bitmap); return ret; } -- 1.7.11.2
