[libvirt] [PATCH v2] vz: handle sourceless cdroms

From: Mikhail Feoktistov <mfeoktistov(a)virtuozzo.com&gt; libvirt handles empty source as NULL, while vz sdk as "" thus we need a bit of conversion. Signed-off-by: Nikolay Shirokovskiy <nshirokovskiy(a)virtuozzo.com&gt; --- src/vz/vz_sdk.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) changes from v1: ================ 1. simplify empty string check in prlsdkGetDiskInfo 2. call setting "" explicitly in prlsdkAddDisk. point 2 is the actual reason for releasing new version. I need this semantics on my future work of updating disks. diff --git a/src/vz/vz_sdk.c b/src/vz/vz_sdk.c index 2e9544b..9b783af 100644 --- a/src/vz/vz_sdk.c +++ b/src/vz/vz_sdk.c @@ -565,7 +565,7 @@ prlsdkGetDiskInfo(vzDriverPtr driver, if (!(buf = prlsdkGetStringParamVar(PrlVmDev_GetFriendlyName, prldisk))) goto cleanup; - if (virDomainDiskSetSource(disk, buf) < 0) + if (*buf != '\0' && virDomainDiskSetSource(disk, buf) < 0) goto cleanup; if (prlsdkGetDiskId(prldisk, isCt, &disk->bus, &disk->dst) < 0) @@ -3183,6 +3183,7 @@ static int prlsdkAddDisk(vzDriverPtr driver, PRL_DEVICE_TYPE devType; PRL_CLUSTERED_DEVICE_SUBTYPE scsiModel; char *dst = NULL; + const char *path = disk->src->path ? : ""; if (disk->device == VIR_DOMAIN_DISK_DEVICE_DISK) devType = PDE_HARD_DISK; @@ -3206,10 +3207,10 @@ static int prlsdkAddDisk(vzDriverPtr driver, pret = PrlVmDev_SetEmulatedType(sdkdisk, emutype); prlsdkCheckRetGoto(pret, cleanup); - pret = PrlVmDev_SetSysName(sdkdisk, disk->src->path); + pret = PrlVmDev_SetSysName(sdkdisk, path); prlsdkCheckRetGoto(pret, cleanup); - pret = PrlVmDev_SetFriendlyName(sdkdisk, disk->src->path); + pret = PrlVmDev_SetFriendlyName(sdkdisk, path); prlsdkCheckRetGoto(pret, cleanup); drive = &disk->info.addr.drive; -- 1.8.3.1
