Re: [libvirt] [PATCH 3/6] vz: check supported disk format and bus

In DomainPostParse phase we check disk format and bus. If disk format is not specified in XML (VIR_STORAGE_FILE_NONE) than we accept this disk. Otherwise we try to find disk format in vzCapabilities struct. Also we try to find disk bus in vzCapabilities->diskBuses. It contains buses that we support. --- src/vz/vz_driver.c | 6 +++++- src/vz/vz_sdk.c | 24 ++---------------------- src/vz/vz_utils.c | 52 ++++++++++++++++++++++++++++++++++++++++++++++++++++ src/vz/vz_utils.h | 3 +++ 4 files changed, 62 insertions(+), 23 deletions(-) diff --git a/src/vz/vz_driver.c b/src/vz/vz_driver.c index 5d48d7e..4f52bc7 100644 --- a/src/vz/vz_driver.c +++ b/src/vz/vz_driver.c @@ -175,8 +175,11 @@ static int vzDomainDefPostParse(virDomainDefPtr def ATTRIBUTE_UNUSED, virCapsPtr caps ATTRIBUTE_UNUSED, unsigned int parseFlags ATTRIBUTE_UNUSED, - void *opaque ATTRIBUTE_UNUSED) + void *opaque) { + if (vzCheckUnsupportedDisks(def, opaque) < 0) + return -1; + return 0; } @@ -239,6 +242,7 @@ vzOpenDefault(virConnectPtr conn) if (!(privconn->caps = vzBuildCapabilities())) goto error; + vzDomainDefParserConfig.priv = &privconn->vzCaps; if (!(privconn->xmlopt = virDomainXMLOptionNew(&vzDomainDefParserConfig, NULL, NULL))) goto error; diff --git a/src/vz/vz_sdk.c b/src/vz/vz_sdk.c index de73c31..2a6e908 100644 --- a/src/vz/vz_sdk.c +++ b/src/vz/vz_sdk.c @@ -3143,30 +3143,10 @@ static int prlsdkAddDisk(PRL_HANDLE sdkdom, pret = PrlVmDev_SetConnected(sdkdisk, 1); prlsdkCheckRetGoto(pret, cleanup); - if (disk->src->type == VIR_STORAGE_TYPE_FILE) { - if (disk->device == VIR_DOMAIN_DISK_DEVICE_DISK && - virDomainDiskGetFormat(disk) != VIR_STORAGE_FILE_PLOOP) { - - virReportError(VIR_ERR_CONFIG_UNSUPPORTED, _("Invalid format of " - "disk %s, vz driver supports only " - "images in ploop format."), disk->src->path); - goto cleanup; - } - + if (disk->src->type == VIR_STORAGE_TYPE_FILE) emutype = PDT_USE_IMAGE_FILE; - } else { - if (disk->device == VIR_DOMAIN_DISK_DEVICE_DISK && - (virDomainDiskGetFormat(disk) != VIR_STORAGE_FILE_RAW && - virDomainDiskGetFormat(disk) != VIR_STORAGE_FILE_NONE && - virDomainDiskGetFormat(disk) != VIR_STORAGE_FILE_AUTO)) { - - virReportError(VIR_ERR_CONFIG_UNSUPPORTED, _("Invalid format " - "of disk %s, it should be either not set, or set " - "to raw or auto."), disk->src->path); - goto cleanup; - } + else emutype = PDT_USE_REAL_DEVICE;
