This patch implements functionality of boot device order based on boot element from os section in XML. Now we support boot from CDROM and HDD. If we have several devices of the same type (for example hdd0 and hdd1), than we mark the first one as bootable. --- src/vz/vz_sdk.c | 111 +++++++++++++++++++++++++++++++++++++++++--------------- 1 file changed, 81 insertions(+), 30 deletions(-) diff --git a/src/vz/vz_sdk.c b/src/vz/vz_sdk.c index 750133d..bebd3b8 100644 --- a/src/vz/vz_sdk.c +++ b/src/vz/vz_sdk.c @@ -2198,6 +2198,78 @@ prlsdkAddDeviceToBootList(PRL_HANDLE sdkdom, return -1; } +static int +prlsdkSetBootDevices(PRL_HANDLE sdkdom, + virDomainDefPtr def) +{ + size_t i; + PRL_RESULT pret; + PRL_HANDLE devList = PRL_INVALID_HANDLE; + PRL_HANDLE dev = PRL_INVALID_HANDLE; + PRL_DEVICE_TYPE currentDevType, bootDevType; + PRL_UINT32 devIndex, devCount, j; + PRL_UINT32 bootSequence = 0; + bool rootMount = false; + + pret = PrlVmCfg_GetAllDevices(sdkdom, &devList); + prlsdkCheckRetGoto(pret, error); + + pret = PrlHndlList_GetItemsCount(devList, &devCount); + prlsdkCheckRetGoto(pret, error); + + for (i = 0; i < def->os.nBootDevs; i++) { + switch (def->os.bootDevs[i]) { + case VIR_DOMAIN_BOOT_CDROM: + bootDevType = PDE_OPTICAL_DISK; + break; + case VIR_DOMAIN_BOOT_DISK: + bootDevType = PDE_HARD_DISK; + break; + default: + continue; + } + + for (j = 0; j < devCount; j++) { + pret = PrlHndlList_GetItem(devList, j, &dev); + prlsdkCheckRetGoto(pret, error); + + pret = PrlVmDev_GetType(dev, &currentDevType); + prlsdkCheckRetGoto(pret, error); + + if (currentDevType == bootDevType) { + pret = PrlVmDev_GetIndex(dev, &devIndex); + prlsdkCheckRetGoto(pret, error); + + if (prlsdkAddDeviceToBootList(sdkdom, devIndex, currentDevType, bootSequence) < 0) + goto error; + bootSequence++; + + if (IS_CT(def) && !rootMount) { + /* If we add physical device as a boot disk to container + we have to specify mount point for it */ + pret = PrlVmDevHd_SetMountPoint(dev, "/"); + prlsdkCheckRetGoto(pret, error); + rootMount = true; + } + } + PrlHandle_Free(dev); + dev = PRL_INVALID_HANDLE; + } + } + + PrlHandle_Free(devList); + return 0; + + error: + if (dev != PRL_INVALID_HANDLE) + PrlHandle_Free(dev); + + if (devList != PRL_INVALID_HANDLE) + PrlHandle_Free(devList); + + return -1; +} + static int prlsdkCheckGraphicsUnsupportedParams(virDomainDefPtr def) { virDomainGraphicsDefPtr gr; @@ -3145,9 +3217,7 @@ static int prlsdkDelDisk(PRL_HANDLE sdkdom, int idx) } static int prlsdkAddDisk(PRL_HANDLE sdkdom, - virDomainDiskDefPtr disk, - bool bootDisk, - bool isCt) + virDomainDiskDefPtr disk) { PRL_RESULT pret; PRL_HANDLE sdkdisk = PRL_INVALID_HANDLE; @@ -3156,7 +3226,6 @@ static int prlsdkAddDisk(PRL_HANDLE sdkdom, PRL_MASS_STORAGE_INTERFACE_TYPE sdkbus; int idx; virDomainDeviceDriveAddressPtr drive; - PRL_UINT32 devIndex; PRL_DEVICE_TYPE devType; char *dst = NULL; @@ -3302,21 +3371,6 @@ static int prlsdkAddDisk(PRL_HANDLE sdkdom, goto cleanup; } - if (bootDisk) { - pret = PrlVmDev_GetIndex(sdkdisk, &devIndex); - prlsdkCheckRetGoto(pret, cleanup); - - if (prlsdkAddDeviceToBootList(sdkdom, devIndex, devType, 0) < 0) - goto cleanup; - - /* If we add physical device as a boot disk to container - * we have to specify mount point for it */ - if (isCt) { - pret = PrlVmDevHd_SetMountPoint(sdkdisk, "/"); - prlsdkCheckRetGoto(pret, cleanup); - } - } - return 0; cleanup: PrlHandle_Free(sdkdisk); @@ -3335,7 +3389,7 @@ prlsdkAttachVolume(virDomainObjPtr dom, virDomainDiskDefPtr disk) if (PRL_FAILED(waitJob(job))) goto cleanup; - ret = prlsdkAddDisk(privdom->sdkdom, disk, false, IS_CT(dom->def)); + ret = prlsdkAddDisk(privdom->sdkdom, disk); if (ret == 0) { job = PrlVm_CommitEx(privdom->sdkdom, PVCF_DETACH_HDD_BUNDLE); if (PRL_FAILED(waitJob(job))) { @@ -3472,7 +3526,7 @@ prlsdkDoApplyConfig(virConnectPtr conn, PRL_RESULT pret; size_t i; char uuidstr[VIR_UUID_STRING_BUFLEN + 2]; - bool needBoot = true; + bool rootfsFound = false; char *mask = NULL; if (prlsdkCheckUnsupportedParams(sdkdom, def) < 0) @@ -3552,21 +3606,18 @@ prlsdkDoApplyConfig(virConnectPtr conn, for (i = 0; i < def->nfss; i++) { if (STREQ(def->fss[i]->dst, "/")) - needBoot = false; + rootfsFound = true; if (prlsdkAddFS(sdkdom, def->fss[i]) < 0) goto error; } for (i = 0; i < def->ndisks; i++) { - bool bootDisk = false; - - if (needBoot && - def->disks[i]->device == VIR_DOMAIN_DISK_DEVICE_DISK) { + if (prlsdkAddDisk(sdkdom, def->disks[i]) < 0) + goto error; + } - needBoot = false; - bootDisk = true; - } - if (prlsdkAddDisk(sdkdom, def->disks[i], bootDisk, IS_CT(def)) < 0) + if (!rootfsFound) { + if (prlsdkSetBootDevices(sdkdom, def) < 0) goto error; } -- 1.8.3.1
