Re: [Libvirt-cim] [PATCH] Patch to allow cdrom media change

# HG changeset patch # User Sharad Mishra <snmishra(a)us.ibm.com&gt; # Date 1291839626 28800 # Node ID b52f1a92d324cb63a942e56ea99c6984c043e2a8 # Parent e82f482d4bd2eae19970f9b9a42caecaf46ebeab Patch to allow cdrom media change. This patch allows VMs with cdrom to change media from one iso to another. This is equivalent to virsh command "virsh attach-disk <vm> <path to iso file> hdc --type cdrom --mode readonly --driver file" Signed-off-by: Sharad Mishra <snmishra(a)us.ibm.com&gt; diff -r e82f482d4bd2 -r b52f1a92d324 libxkutil/device_parsing.c --- a/libxkutil/device_parsing.c Tue Nov 30 13:33:45 2010 -0500 +++ b/libxkutil/device_parsing.c Wed Dec 08 12:20:26 2010 -0800 @@ -1179,6 +1179,28 @@ } +static int change_disk(virDomainPtr dom, + struct virt_device *dev) +{ + + char *xml = NULL; + int ret = 0; + + xml = device_to_xml(dev); + + CU_DEBUG("New XML is %s", xml); + + if (virDomainAttachDevice(dom, xml) != 0) { + goto out; + } + + ret = 1; + out: + free(xml); + + return ret; +} + static int change_memory(virDomainPtr dom, struct virt_device *dev) { @@ -1246,8 +1268,10 @@ { if (dev->type == CIM_RES_TYPE_MEM) return change_memory(dom, dev); - else if (dev->type == CIM_RES_TYPE_PROC) + if (dev->type == CIM_RES_TYPE_PROC) return change_vcpus(dom, dev); + if (dev->type == CIM_RES_TYPE_DISK) + return change_disk(dom, dev) ; CU_DEBUG("Unhandled device type %i", dev->type); diff -r e82f482d4bd2 -r b52f1a92d324 src/Virt_VirtualSystemManagementService.c --- a/src/Virt_VirtualSystemManagementService.c Tue Nov 30 13:33:45 2010 -0500 +++ b/src/Virt_VirtualSystemManagementService.c Wed Dec 08 12:20:26 2010 -0800 @@ -836,6 +836,7 @@ const char *val = NULL; uint16_t type; + CU_DEBUG("Enter disk_rasd_to_vdev"); if (cu_get_str_prop(inst, "VirtualDevice", &val) != CMPI_RC_OK) return "Missing `VirtualDevice' property"; @@ -863,6 +864,8 @@ dev->dev.disk.device = strdup("floppy"); else return "Invalid value for EmulatedType"; + + CU_DEBUG("device type is %s", dev->dev.disk.device); free(dev->dev.disk.bus_type); if (cu_get_str_prop(inst, "BusType", &val) != CMPI_RC_OK) @@ -1411,6 +1414,7 @@ virConnectPtr conn = NULL; virDomainPtr dom = NULL; + CU_DEBUG("Enter update_dominfo"); if (dominfo->dev_vcpu_ct != 1) { /* Right now, we only have extra info for processors */ CU_DEBUG("Domain has no vcpu devices!"); @@ -1444,10 +1448,12 @@ infostore_set_u64(ctx, "limit", dev->dev.vcpu.limit); dev = dominfo->dev_graphics; - if (dev->dev.graphics.passwd != NULL) - infostore_set_bool(ctx, "has_vnc_passwd", true); - else - infostore_set_bool(ctx, "has_vnc_passwd", false); + if(dev != NULL){ + if (dev->dev.graphics.passwd != NULL) + infostore_set_bool(ctx, "has_vnc_passwd", true); + else + infostore_set_bool(ctx, "has_vnc_passwd", false); + } out: infostore_close(ctx); @@ -2068,6 +2074,7 @@ virDomainPtr dom; int (*func)(virDomainPtr, struct virt_device *); + CU_DEBUG("Enter _resource_dynamic"); if (action == RESOURCE_ADD) func = attach_device; else if (action == RESOURCE_DEL) @@ -2292,6 +2299,7 @@ int i; const char *msg = NULL; + CU_DEBUG("Enter resource_mod"); if (devid == NULL) { cu_statusf(_BROKER, &s, CMPI_RC_ERR_INVALID_PARAMETER, @@ -2361,8 +2369,10 @@ const char *indication; CMPIObjectPath *op; struct inst_list list; - CMPIInstance *prev_inst = NULL; + CMPIInstance *prev_inst = NULL; + CMPIInstance *orig_inst = NULL; + CU_DEBUG("Enter _update_resources_for"); inst_list_init(&list); if (!get_dominfo(dom, &dominfo)) { virt_set_status(_BROKER, &s, @@ -2406,14 +2416,23 @@ dummy_name, type, NULL, - &prev_inst); + &orig_inst); free(dummy_name); if (s.rc != CMPI_RC_OK) { CU_DEBUG("Failed to get Previous Instance"); goto out; } - } + + s = cu_merge_instances(rasd, orig_inst); + if (s.rc != CMPI_RC_OK) { + CU_DEBUG("Failed to merge Instances"); + goto out; + } + prev_inst = orig_inst; + rasd = orig_inst; + + } s = func(dominfo, rasd, type, devid, NAMESPACE(ref)); if (s.rc != CMPI_RC_OK) { @@ -2487,6 +2506,7 @@ int count; uint32_t rc = CIM_SVPC_RETURN_FAILED; + CU_DEBUG("Enter _update_resource_settings"); conn = connect_by_classname(_BROKER, CLASSNAME(ref), &s); if (conn == NULL) { cu_statusf(_BROKER, &s, @@ -2731,6 +2751,7 @@ CMPIArray *res = NULL; struct inst_list list; + CU_DEBUG("Enter mod_resource_settings"); inst_list_init(&list); if (cu_get_array_arg(argsin, "ResourceSettings", &arr) != CMPI_RC_OK) { _______________________________________________ Libvirt-cim mailing list Libvirt-cim(a)redhat.com https://www.redhat.com/mailman/listinfo/libvirt-cim
