[libvirt] [PATCH RFC 0/5] add support for scsi-generic for virtio-scsi
by Han Cheng 21 Mar '13

21 Mar '13

This patch series tried to implement the fifth part of Paolo's proposal: http://permalink.gmane.org/gmane.comp.emulators.libvirt/50428 It is not completed. But it may for use. Needs some more works on: src/qemu/qemu_hostdev.c src/qemu/qemu_hotplug.c We may also need create src/util/virscsi.[hc] like src/util/vir(pci|usb).[hc], add sg* to nodedev tree and some others. As scsi hostdev needs -drive and -device like disk. There are two approaches: a) build a disk then use the disk related functions, b) create new function for it. I chose the last one as it is clearer and easier. But this may create some redundant codes. Any ideas?

[libvirt] [PATCH] Fix linkage of virt-aa-helper with numa library
by Daniel P. Berrange 21 Mar '13

21 Mar '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> The recent commit moved some of the use of libnuma out of the driver code, and into src/util/. It did not, however, update libvirt_util.la to link against libnuma. This caused linkage failure with virt-aa-helper, since nothing else caused libnuma to be pulled onto the linker command line. The fix removes all reference to NUMACTL_LIBS/CFLAGS from the various modules in src/Makefile.am and just adds them to the libvirt_util.la module, which everything else depends on. Technically a build-breaker fix, but wanted to wait for feedback on this Signed-off-by: Daniel P.

[libvirt] [PATCH] python: fix about some of python binding APIs don't raise and exception
by Guannan Ren 21 Mar '13

21 Mar '13

For example: >>> dom.memoryStats() libvir: QEMU Driver error : Requested operation is not valid:\ domain is not running There are six such python API functions like so. The root reason is that generator.py script checks the type of return value of a python stub function defined in libvirt-api.xml or libvirt-override-api.xml to see whether adding the raise clause or not in python wrapper code in libvirt.py. The type of return value is supposed to be C types. For those stub functions which return python non-integer data type like string, list, tuple, dictionary, the existing type in functions varies from each other which leads problem like this. Currently, in generator.py, it maintains a buggy whitelist for stub functions returning a list type. I think it is easy to forget adding new function name in the whitelist. This patch makes the value of type consistent with C type "char *" in libvirt-override-api.xml. For python, any of types could be printed as string, so I choose "char *"in this case. And the comment in xml could explain it when adding new function definition. <function name='virNodeGetCPUStats' file='python'> ... - <return type='virNodeCPUStats' info='...'/> + <return type='char *' info='...'/> ... </function> --- python/generator.py | 10 ++-- python/libvirt-override-api.xml | 116 +++++++++++++++++++++------------------- 2 files changed, 66 insertions(+), 60 deletions(-) diff --git a/python/generator.py b/python/generator.py index 8236bd2..bebc644 100755 --- a/python/generator.py +++ b/python/generator.py @@ -1008,11 +1008,9 @@ functions_list_exception_test = { } functions_list_default_test = "%s is None" -def is_list_type (name): - whitelist = [ "virDomainBlockStats", - "virDomainInterfaceStats" ] +def is_python_noninteger_type (name): - return name[-1:] == "*" or name in whitelist + return name[-1:] == "*" def nameFixup(name, classe, type, file): # avoid a desastrous clash @@ -1386,7 +1384,7 @@ def buildWrappers(module): ("ret", name)) classes.write(" return ret\n") - elif is_list_type (ret[0]): + elif is_python_noninteger_type (ret[0]): if not functions_noexcept.has_key (name): if functions_list_exception_test.has_key (name): test = functions_list_exception_test[name] @@ -1656,7 +1654,7 @@ def buildWrappers(module): classes.write (" return ret\n") - elif is_list_type (ret[0]): + elif is_python_noninteger_type (ret[0]): if not functions_noexcept.has_key (name): if functions_list_exception_test.has_key (name): test = functions_list_exception_test[name] diff --git a/python/libvirt-override-api.xml b/python/libvirt-override-api.xml index 5976fb2..6087f86 100644 --- a/python/libvirt-override-api.xml +++ b/python/libvirt-override-api.xml @@ -1,5 +1,13 @@ <?xml version="1.0"?> <api name='libvir-python'> +  <symbols> <function name="virConnectGetVersion" file='python'> <info>Returns the running hypervisor version of the connection host</info> @@ -14,34 +22,34 @@ <function name="virConnectListDomainsID" file='python'> <info>Returns the list of the ID of the domains on the hypervisor</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> - <return type='int *' info="the list of ID or None in case of error"/> + <return type='char *' info="the list of ID or None in case of error"/> </function> <function name='virConnectListDefinedDomains' file='python'> <info>list the defined domains, stores the pointers to the names in @names</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> - <return type='str *' info='the list of Names or None in case of error'/> + <return type='char *' info='the list of Names or None in case of error'/> </function> <function name='virConnectListAllDomains' file='python'> <info>returns list of all defined domains</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> <arg name='flags' type='unsigned int' info='optional flags'/> - <return type='domain *' info='the list of domains or None in case of error'/> + <return type='char *' info='the list of domains or None in case of error'/> </function> <function name='virConnectListNetworks' file='python'> <info>list the networks, stores the pointers to the names in @names</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> - <return type='str *' info='the list of Names or None in case of error'/> + <return type='char *' info='the list of Names or None in case of error'/> </function> <function name='virConnectListDefinedNetworks' file='python'> <info>list the defined networks, stores the pointers to the names in @names</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> - <return type='str *' info='the list of Names or None in case of error'/> + <return type='char *' info='the list of Names or None in case of error'/> </function> <function name='virConnectListAllNetworks' file='python'> <info>returns list of all networks</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> <arg name='flags' type='unsigned int' info='optional flags'/> - <return type='network *' info='the list of networks or None in case of error'/> + <return type='char *' info='the list of networks or None in case of error'/> </function> <function name='virDomainLookupByUUID' file='python'> <info>Try to lookup a domain on the given hypervisor based on its UUID.</info> @@ -57,54 +65,54 @@ </function> <function name='virDomainGetInfo' file='python'> <info>Extract information about a domain.

According to the code, if we use "<disk type='block' device='disk'> " and "<shareable/> " to set the disk's configuration in VM's XML file, it will go through like below: int qemuAddSharedDisk(virQEMUDriverPtr driver, virDomainDiskDefPtr disk, const char *name) { ... if (!(key = qemuGetSharedDiskKey(disk->src))) goto cleanup; ... } char * qemuGetSharedDiskKey(const char *disk_path) { ... if ((rc = virGetDeviceID(disk_path, &maj, &min)) < 0) { virReportSystemError(-rc, _("Unable to get minor number of device '%s'"), disk_path); return NULL; } ... } int virGetDeviceID(const char *path, int *maj, int *min) { struct stat sb; if (stat(path, &sb) < 0) return -errno; if (!S_ISBLK(sb.st_mode)) return -EINVAL; if (maj) *maj = major(sb.st_rdev); if (min) *min = minor(sb.st_rdev); return 0; } To make a long story short, the virGetDeviceID fuction want to get the maj and min number of the source file which we provided as the VM's disk. But the file such as /mnt/test.raw doesn't have the maj and min number. So virGetDeviceID return " -EINVAL" and qemuGetSharedDiskKey print the error message of "Unable to get minor number of device /mnt/test.raw". That's the reason the VM can't be started. So I just want to know now, if the way I used a file to act as VM's disk and set "<disk type='block' device='disk'>" , "<shareable/> " at the same time is reasonable.

HI,buddy. I'm sheldon. I'm trying to develop virtual machine lifecycle management software using libvirt. I found the development guide is very useful,it helps a lot. But this book I download from offical website is a draft,there are a lot of funcitons which are not claimed. I appreciate very much that you give me some document that developers are being in reference to . Best wishes! keep in touch. Yours sincely! .

[libvirt] [PATCH] python: Fix emulatorpin API bindings
by Peter Krempa 20 Mar '13

20 Mar '13

The addition of emulator pinning APIs didn't think of doing the right job with python APIs for them. The default generator produced unusable code for this. This patch switches to proper code as in the case of domain Vcpu pining. This change can be classified as a python API-breaker but in the state the code was before I doubt anyone was able to use it successfully. --- python/generator.py | 2 + python/libvirt-override-api.xml | 18 +++++- python/libvirt-override.c | 121 ++++++++++++++++++++++++++++++++++++++++ 3 files changed, 139 insertions(+), 2 deletions(-) diff --git a/python/generator.py b/python/generator.py index 6a25c2d..0aeb675 100755 --- a/python/generator.py +++ b/python/generator.py @@ -418,6 +418,8 @@ skip_impl = ( 'virDomainPinVcpu', 'virDomainPinVcpuFlags', 'virDomainGetVcpuPinInfo', + 'virDomainGetEmulatorPinInfo', + 'virDomainPinEmulator', 'virSecretGetValue', 'virSecretSetValue', 'virSecretGetUUID', diff --git a/python/libvirt-override-api.xml b/python/libvirt-override-api.xml index 5976fb2..c720610 100644 --- a/python/libvirt-override-api.xml +++ b/python/libvirt-override-api.xml @@ -237,10 +237,24 @@ <function name='virDomainGetVcpuPinInfo' file='python'> <info>Query the CPU affinity setting of all virtual CPUs of domain</info> <return type='unsigned char *' info='the array of cpumap'/> - <arg name='domain' type='virDomainPtr' info='pointer to domain object, or NULL for Domain0'/> + <arg name='domain' type='virDomainPtr' info='pointer to domain object'/> + <arg name='flags' type='int' info='an OR'ed set of virDomainModificationImpact'/> + </function> + <function name='virDomainGetEmulatorPinInfo' file='python'> + <info>Query the CPU affinity setting of the emulator process of domain</info> + <return type='unsigned char *' info='the array of cpumap'/> + <arg name='domain' type='virDomainPtr' info='pointer to domain object'/> <arg name='flags' type='int' info='an OR'ed set of virDomainModificationImpact'/> </function> - <function name='virDomainSetSchedulerParameters' file='python'> + <function name='virDomainPinEmulator' file='python'> + <info>Dynamically change the real CPUs which can be allocated to the emulator process of a domain. + This function requires privileged access to the hypervisor.</info> + <return type='int' info='0 in case of success, -1 in case of failure.'/> + <arg name='domain' type='virDomainPtr' info='pointer to domain object, or NULL for Domain0'/> + <arg name='cpumap' type='unsigned char *' info='pointer to a bit map of real CPUs (in 8-bit bytes) (IN) Each bit set to 1 means that corresponding CPU is usable.

[libvirt] [libvirt-designer PATCHv2] Add GvirDesignerDomain::osinfo_db
by Christophe Fergeau 20 Mar '13

20 Mar '13

virtxml was doing its own loading of the libosinfo database, and gvir_designer_init() was loading it a second time. By adding a GVirDesignerDomain::osinfo_db property, applications can share the same OsinfoDb as libvirt-designer. The association is made per libvirt-designer domain for more flexibility. If no OsinfoDb is associated with a domain when needed, libvirt-designer will automatically try to load it. --- examples/virtxml.c | 2 ++ libvirt-designer/libvirt-designer-domain.c | 49 +++++++++++++++++++++++++++- libvirt-designer/libvirt-designer-internal.h | 3 -- libvirt-designer/libvirt-designer-main.c | 12 ------- libvirt-designer/libvirt-designer-main.h | 2 ++ libvirt-designer/libvirt-designer.sym | 1 + 6 files changed, 53 insertions(+), 16 deletions(-) diff --git a/examples/virtxml.c b/examples/virtxml.c index a68843d..be6ee7a 100644 --- a/examples/virtxml.c +++ b/examples/virtxml.c @@ -559,6 +559,8 @@ main(int argc, char *argv[]) } domain = gvir_designer_domain_new(os, platform, caps);

[libvirt] [PATCH v3] add a boot option to do strict boot
by Amos Kong 19 Mar '13

19 Mar '13

Seabios already added a new device type to halt booting. Qemu can add "HALT" at the end of bootindex string, then seabios will halt booting after trying to boot from all selected devices. This patch added a new boot option to configure if boot from un-selected devices. This option only effects when boot priority is changed by bootindex options, the old style(-boot order=..) will still try to boot from un-selected devices. v2: add HALT entry in get_boot_devices_list() v3: rebase to latest qemu upstream Signed-off-by: Amos Kong <akong(a)redhat.com> --- As we discussed in the past, we need to introduce a general query-config command to tell libvirt the supported options.

[libvirt] [PATCH 0/5]Add startupPolicy attribute support for hard disks
by Guannan Ren 19 Mar '13

19 Mar '13

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. virBitmapNextLastSetBit: Search for the last clear bit before certain position.

[libvirt] [ANNOUNCE] libvirt-glib 0.1.6 release
by Daniel P. Berrange 18 Mar '13

18 Mar '13

I am pleased to announce that a new release of the libvirt-glib package, version 0.1.6, is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) New in this release: - Prefer g_strlcpy over strncpy - Fix potential crashes in some error handling cases - Fix typo in gvir_config_init docs which broke vala binding - Use 'transfer none' for argv parameter in all init functions - Ensure stream data parameters are annotated to be guint8 arrays, not gchar, since they're not NULL terminated strings. - Replace FSF address with URL in copyright headers - Add API for changing Spice compression parameters. libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable forever, with libvirt-glib we are not yet guaranteeing that libvirt-glib libraries are API/ABI permanently stable. As of the 0.0.8 release, we have tentatively frozen the API/ABI with the intent of being longterm stable hereafter, but there is still a small chance we might find flaws requiring an API/ABI change. The likelihood of this is low, however, and we will strive to avoid it. Follow up comments about libvirt-glib should be directed to the regular libvir-list(a)redhat.com development list. Thanks to all the people involved in contributing to this release.

[libvirt] [PATCH v8 0/3] DEVICE_DELETED event
by Michael S. Tsirkin 18 Mar '13

18 Mar '13

libvirt has a long-standing bug: when removing the device, it can request removal but does not know when the removal completes. Add an event so we can fix this in a robust way. First patch only adds the event with ID, second patch adds a path field. Split this way for ease of backport (stable downstreams without QOM would want to only take the first patch). Event without fields is still useful as management can use it to poll device list to figure out which device was removed. Signed-off-by: Michael S. Tsirkin <mst(a)redhat.com> If there are no more comments I'll stick this on my pci branch. Changes from v7: - none, v7 was malformed series sent by mistake Changes from v6: - make empty event use data: {}, Markus prefers this Changes from v5: - Emit an empty event on unnamed devices in patch 1/3, as suggested by Markus Changes from v4: - Add extra triggers and extra fields as requested by Markus Changes from v3: - Document that we only emit events for devices with and ID, as suggested by Markus Changes from v2: - move event toward the end of device_unparent, so that parents are reported after their children, as suggested by Paolo Changes from v1: - move to device_unparent - address comments by Andreas and Eric -- Anthony Liguori Michael S.

[libvirt] [PATCH] qemu: Fix startupPolicy regression
by Jiri Denemark 18 Mar '13

18 Mar '13

Commit 82d5fe543720da6d83c1d6bfa1c347d7d9fda278 qemu: check backing chains even when cgroup is omitted added backing file checks just before the code that removes optional disks if they are not present. However, the backing chain code fails in case the disk file does not exist, which makes qemuProcessStart fail regardless on configured startupPolicy. Note that startupPolicy implementation is still wrong after this patch since it only check the first file in a possible chain. It should rather check the complete backing chain. But this is an existing limitation that can be solved later. After all, startupPolicy is most useful for CDROM images and they won't make use of backing files in most cases. --- src/qemu/qemu_process.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 1941d4e..3d2b7d6 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -3621,14 +3621,15 @@ int qemuProcessStart(virConnectPtr conn, goto cleanup; VIR_DEBUG("Checking for CDROM and floppy presence"); + if (qemuDomainCheckDiskPresence(driver, vm, + flags & VIR_QEMU_PROCESS_START_COLD) < 0) + goto cleanup; + for (i = 0; i < vm->def->ndisks ; i++) { if (qemuDomainDetermineDiskChain(driver, vm->def->disks[i], false) < 0) goto cleanup; } - if (qemuDomainCheckDiskPresence(driver, vm, - flags & VIR_QEMU_PROCESS_START_COLD) < 0) - goto cleanup; /* Get the advisory nodeset from numad if 'placement' of * either <vcpu> or <numatune> is 'auto'. -- 1.8.1.5

[libvirt] Tails bounty for supporting the 'removable' flag for USB disks
by intrigeri 17 Mar '13

17 Mar '13

Hello, I'm part of the people developing the live system called Tails [1]. [1] https://tails.boum.org/ We are now preparing a bounties program to help developers work on upstream software and fix bugs or implement features needed for Tails. Daniel P. Berrange suggested we write to this list about it. More specifically, for our libvirt-based test suite, we need a way to emulate both removable and non-removable USB 2.0+ devices. This distinction is supported in QEMU since --device can receive an optional removable= property. So, what we lack is a way to tell libvirt to pass this or that value to QEMU for the removable= property of a given emulated USB 2.0+ device. For instance, on a Linux guest it controls the value of /sys/block/$dev/removable. We propose a USD $3000 bounty to implement this feature. We are already in contact with someone who is very interested in doing this work. Ticket: https://bugzilla.redhat.com/show_bug.cgi?id=922495 Thanks for your work on libvirt! Cheers, -- intrigeri | GnuPG key @ https://gaffer.ptitcanardnoir.org/intrigeri/intrigeri.asc | OTR fingerprint @ https://gaffer.ptitcanardnoir.org/intrigeri/otr.asc

The audit logs look like: For the 'random' backend: type=VIRT_RESOURCE msg=audit(1363099126.643:31): pid=995252 uid=0 auid=4294967295 ses=4294967295 msg='virt=kvm resrc=rng reason=start vm="qcow-test" uuid=118733ed-b658-3e22-a2cb-4fe5cb3ddf79 old-rng="?" new-rng="/dev/random": exe="/home/pipo/libvirt/daemon/.libs/libvirtd" hostname=? addr=? terminal=pts/0 res=success' For local character device source: type=VIRT_RESOURCE msg=audit(1363100164.240:96): pid=995252 uid=0 auid=4294967295 ses=4294967295 msg='virt=kvm resrc=rng reason=start vm="qcow-test" uuid=118733ed-b658-3e22-a2cb-4fe5cb3ddf79 old-rng="?" new-rng="/tmp/unix.sock": exe="/home/pipo/libvirt/daemon/.libs/libvirtd" hostname=? addr=? terminal=pts/0 res=success' --- Notes: Version 3: - don't log non-local resources for EGD backend - change order of blocks of code to optimize Version 2: - log also EGD backends - add example of audit message to commit message src/conf/domain_audit.c | 120 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 120 insertions(+) diff --git a/src/conf/domain_audit.c b/src/conf/domain_audit.c index 8cd522a..a776058 100644 --- a/src/conf/domain_audit.c +++ b/src/conf/domain_audit.c @@ -57,6 +57,37 @@ virDomainAuditGetRdev(const char *path ATTRIBUTE_UNUSED) } #endif + +static const char * +virDomainAuditChardevPath(virDomainChrSourceDefPtr chr) +{ + if (!chr) + return NULL; + + switch ((enum virDomainChrType) chr->type) { + case VIR_DOMAIN_CHR_TYPE_PTY: + case VIR_DOMAIN_CHR_TYPE_DEV: + case VIR_DOMAIN_CHR_TYPE_FILE: + case VIR_DOMAIN_CHR_TYPE_PIPE: + return chr->data.file.path; + + case VIR_DOMAIN_CHR_TYPE_UNIX: + return chr->data.nix.path; + + case VIR_DOMAIN_CHR_TYPE_TCP: + case VIR_DOMAIN_CHR_TYPE_UDP: + case VIR_DOMAIN_CHR_TYPE_NULL: + case VIR_DOMAIN_CHR_TYPE_VC: + case VIR_DOMAIN_CHR_TYPE_STDIO: + case VIR_DOMAIN_CHR_TYPE_SPICEVMC: + case VIR_DOMAIN_CHR_TYPE_LAST: + return NULL; + } + + return NULL; +} + + void virDomainAuditDisk(virDomainObjPtr vm, const char *oldDef, const char *newDef, @@ -100,6 +131,92 @@ cleanup: } +static void +virDomainAuditRNG(virDomainObjPtr vm, + virDomainRNGDefPtr newDef, virDomainRNGDefPtr oldDef, + const char *reason, bool success) +{ + char uuidstr[VIR_UUID_STRING_BUFLEN]; + char *vmname; + const char *newsrcpath = NULL; + const char *oldsrcpath = NULL; + char *oldsrc = NULL; + char *newsrc = NULL; + const char *virt; + + if (newDef) { + switch ((enum virDomainRNGBackend) newDef->backend) { + case VIR_DOMAIN_RNG_BACKEND_RANDOM: + if (newDef->source.file) + newsrcpath = newDef->source.file; + else + newsrcpath = "/dev/random"; + break; + + case VIR_DOMAIN_RNG_BACKEND_EGD: + newsrcpath = virDomainAuditChardevPath(newDef->source.chardev); + break; + + case VIR_DOMAIN_RNG_BACKEND_LAST: + break; + } + } + + if (oldDef) { + switch ((enum virDomainRNGBackend) oldDef->backend) { + case VIR_DOMAIN_RNG_BACKEND_RANDOM: + if (oldDef->source.file) + oldsrcpath = oldDef->source.file; + else + oldsrcpath = "/dev/random"; + break; + + case VIR_DOMAIN_RNG_BACKEND_EGD: + oldsrcpath = virDomainAuditChardevPath(oldDef->source.chardev); + break; + + case VIR_DOMAIN_RNG_BACKEND_LAST: + break; + } + } + + /* don't audit the RNG device if it doesn't use local resources */ + if (!oldsrcpath && !newsrcpath) + return; + + virUUIDFormat(vm->def->uuid, uuidstr); + if (!(vmname = virAuditEncode("vm", vm->def->name))) + goto no_memory; + + if (!(virt = virDomainVirtTypeToString(vm->def->virtType))) { + VIR_WARN("Unexpected virt type %d while encoding audit message", + vm->def->virtType); + virt = "?"; + } + + if (!(newsrc = virAuditEncode("new-rng", VIR_AUDIT_STR(newsrcpath)))) + goto no_memory; + + if (!(oldsrc = virAuditEncode("old-rng", VIR_AUDIT_STR(oldsrcpath)))) + goto no_memory; + + VIR_AUDIT(VIR_AUDIT_RECORD_RESOURCE, success, + "virt=%s resrc=rng reason=%s %s uuid=%s %s %s", + virt, reason, vmname, uuidstr, + oldsrc, newsrc); + +cleanup: + VIR_FREE(vmname); + VIR_FREE(oldsrc); + VIR_FREE(newsrc); + return; + +no_memory: + VIR_WARN("OOM while encoding audit message"); + goto cleanup; +} + + void virDomainAuditFS(virDomainObjPtr vm, virDomainFSDefPtr oldDef, virDomainFSDefPtr newDef, @@ -641,6 +758,9 @@ virDomainAuditStart(virDomainObjPtr vm, const char *reason, bool success) virDomainAuditRedirdev(vm, redirdev, "start", true); } + if (vm->def->rng) + virDomainAuditRNG(vm, vm->def->rng, NULL, "start", true); + virDomainAuditMemory(vm, 0, vm->def->mem.cur_balloon, "start", true); virDomainAuditVcpu(vm, 0, vm->def->vcpus, "start", true); -- 1.8.1.5

[libvirt] [PATCH 0/3] Fix virsh race and coredump
by Viktor Mihajlovski 15 Mar '13

15 Mar '13

I hope that this is an acceptable solution. The race is caused by referencing a disposed connection object in a callback. In the first patch we make sure that the object reference count is reflecting the callback registration. The second patch prevents the invocation of a NULL callback. The last one tries to ensure that we don't leak connection references.

[libvirt] [PATCH V1 0/6] Add support for guests with TPM passthrough device
by Stefan Berger 15 Mar '13

15 Mar '13

Hello! The following set of patches adds support to libvirt for adding a TPM passthrough device to a QEMU guest. Support for this was recently accepted into QEMU. This set of patches borrows a lot from the recently added support for rng's. This patch series builds on top of the patches for adding support for file descriptor sets. Regards, Stefan

[libvirt] [PATCH] remote: Prevent race when closing a connection
by Viktor Mihajlovski 15 Mar '13

15 Mar '13

A race condition can occur when virConnectClose is called parallel to the execution of the connection close callback in remoteClientCloseFunc. The race happens if the connection object is destroyed (including the mutex) while remoteClientCloseFunc is waiting for the connection mutex. After the destruction of the (non error checking) mutex remoteClientCloseFunc starts to process the callbacks. However the operations can occur against a freed (or even worse, reallocated) object. Another issue is that the closeFreeCallback is invoked even if it's NULL (this is the case for virsh). The solution is to clean out the callback pointers in virConnectDispose before destroying the mutex. This way remoteClientCloseFunc will return immediately after passing virMutexLock, thus avoiding potential data corruption. There's still the slight chance that the concluding virMutexUnlock could do harm on the freed connection object. This could be fixed using an error checking mutex which however has a much broader scope and impact.

[libvirt] [PATCHv2 1/1] Remove contiguous CPU indexes assumption
by Li Zhang 15 Mar '13

15 Mar '13

From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> When getting CPUs' information, it assumes that CPU indexes are not contiguous. But for ppc64 platform, CPU indexes are not contiguous because SMT is needed to be disabled, so CPU information is not right on ppc64 and vpuinfo, vcpupin can't work corretly. This patch is to remove the assumption to be compatible with ppc64. Test: 4 vcpus are assigned to one VM and execute vcpuinfo command. Without patch: There is only one vcpu informaion can be listed. With patch: All vcpus' information can be listed correctly.

[libvirt] [PATCH v2 1/2] json: add stream parser
by Dmitry Guryanov 15 Mar '13

15 Mar '13

Add function virJSONValueFromStream, which reads data from a stream and passes it to json parser. When end of the object is reached, it returns this object. To avoid reading from the stream by single bytes it reads to a buffer (in a structure virJSONStreamParserState), which should be passed to a consequent call of this function. So if the end of one object and the beginning of the next object have been read by a single system call - virJSONValueFromStream handle it correctly. example of usage: virJSONValuePtr v; virJSONStreamParserState state; memset(&state, 0, sizeof(state)); while (1) { v = virJSONValueFromStream(mon->fd, &state); if (v == (void *)-1) /* error */ break; if (v == NULL) /* file descriptor has been closed */ break; /* handle object 'v' */ } I need such function for the parallels driver. It caches info about domains and needs some mechanism to update this cache. There is a "prlsrvctl monitor" command which waits for events forever and prints info about events to stdout in json format. So parallels driver could start separate thread which will read from prlsrvctl's stdout and update cache accordingly. There is the same task in qemu_monitor_json, but each json object is printed in a separate line there. It's not possible in my case, because some fields could have line endings.

[libvirt] [libvirt-sandbox][PATCH] Avoid segfault if broadcast address is NULL
by Alex Jia 15 Mar '13

15 Mar '13

It seems the broadcast address parameter is not optional now, if users haven't specified the broadcast address to the network interface then a segfault will be raised. This patch is just a temporary solution to avoid segfault, and with the patch, users will get a expected error "Unable to parse networks: Unable to parse broadcast address (null)", of course, a better patch should automatically generate a broadcast address according to actual ip address. But AFAIK, the IPv6 hasn't defined broadcast address, so it needs to do address protocol judgement firstly, I will try to implement it later. * How to reproduce? # virt-sandbox -c lxc:/// --network address=192.168.122.1 /bin/sh or # virt-sandbox -c lxc:/// --network address=192.168.122.1/24 /bin/sh Signed-off-by: Alex Jia <ajia(a)redhat.com> --- libvirt-sandbox/libvirt-sandbox-config.c | 8 ++++++++ 1 files changed, 8 insertions(+), 0 deletions(-) diff --git a/libvirt-sandbox/libvirt-sandbox-config.c b/libvirt-sandbox/libvirt-sandbox-config.c index 3dc453a..f392f4b 100644 --- a/libvirt-sandbox/libvirt-sandbox-config.c +++ b/libvirt-sandbox/libvirt-sandbox-config.c @@ -873,6 +873,14 @@ gboolean gvir_sandbox_config_add_network_strv(GVirSandboxConfig *config, goto cleanup; } + if (!bcast) { + g_set_error(error, GVIR_SANDBOX_CONFIG_ERROR, 0, + "Unable to parse broadcast address %s", bcast); + g_free(primary); + goto cleanup; + + } + if (!(bcastaddr = g_inet_address_new_from_string(bcast))) { g_set_error(error, GVIR_SANDBOX_CONFIG_ERROR, 0, "Unable to parse address %s", bcast); -- 1.7.1

[libvirt] [PATCH v6 0/3] DEVICE_DELETED event
by Michael S. Tsirkin 15 Mar '13

15 Mar '13

libvirt has a long-standing bug: when removing the device, it can request removal but does not know when the removal completes. Add an event so we can fix this in a robust way. First patch only adds the event with ID, second patch adds a path field. Split this way for ease of backport (stable downstreams without QOM would want to only take the first patch). Event without fields is still useful as management can use it to poll device list to figure out which device was removed. Signed-off-by: Michael S. Tsirkin <mst(a)redhat.com> Changes from v5: - Emit an empty event on unnamed devices in patch 1/3, as suggested by Markus Changes from v4: - Add extra triggers and extra fields as requested by Markus Changes from v3: - Document that we only emit events for devices with and ID, as suggested by Markus Changes from v2: - move event toward the end of device_unparent, so that parents are reported after their children, as suggested by Paolo Changes from v1: - move to device_unparent - address comments by Andreas and Eric -- Anthony Liguori Michael S.

[libvirt] [PATCH] util: fix clear_emulator_capabilities=0
by Laine Stump 14 Mar '13

14 Mar '13

My commit 7a2e845a865dc7fa82d2393ea2a770cfc8cf00b4 (and its prerequisites) managed to effectively ignore the clear_emulator_capabilities setting in qemu.conf (visible in the code as the VIR_EXEC_CLEAR_CAPS flag when qemu is being exec'ed), with the result that the capabilities are always cleared regardless of the qemu.conf setting. This patch fixes it by passing the flag through to virSetUIDGIDWithCaps(), which uses it to decide whether or not to clear existing capabilities before adding in those that were requested. Note that the existing capabilities are *always* cleared if the new process is going to run as non-root, since the whole point of running non-root is to have the capabilities removed (it's still possible to add back individual capabilities as needed though). --- This will need to be backported to v1.0.3-maint. src/util/vircommand.c | 4 +++- src/util/virutil.c | 16 ++++++++++------ src/util/virutil.h | 3 ++- 3 files changed, 15 insertions(+), 8 deletions(-) diff --git a/src/util/vircommand.c b/src/util/vircommand.c index f672101..08d3d29 100644 --- a/src/util/vircommand.c +++ b/src/util/vircommand.c @@ -639,8 +639,10 @@ virExec(virCommandPtr cmd) cmd->capabilities || (cmd->flags & VIR_EXEC_CLEAR_CAPS)) { VIR_DEBUG("Setting child uid:gid to %d:%d with caps %llx", (int)cmd->uid, (int)cmd->gid, cmd->capabilities); - if (virSetUIDGIDWithCaps(cmd->uid, cmd->gid, cmd->capabilities) < 0) + if (virSetUIDGIDWithCaps(cmd->uid, cmd->gid, cmd->capabilities, + (cmd->flags & VIR_EXEC_CLEAR_CAPS)) < 0) { goto fork_error; + } } if (cmd->pwd) { diff --git a/src/util/virutil.c b/src/util/virutil.c index 4605c78..634b7e3 100644 --- a/src/util/virutil.c +++ b/src/util/virutil.c @@ -2998,18 +2998,21 @@ virGetGroupName(gid_t gid ATTRIBUTE_UNUSED) * errno). */ int -virSetUIDGIDWithCaps(uid_t uid, gid_t gid, unsigned long long capBits) +virSetUIDGIDWithCaps(uid_t uid, gid_t gid, unsigned long long capBits, + bool clearExistingCaps) { int ii, capng_ret, ret = -1; bool need_setgid = false, need_setuid = false; bool need_prctl = false, need_setpcap = false; - /* First drop all caps except those in capBits + the extra ones we - * need to change uid/gid and change the capabilities bounding - * set. + /* First drop all caps (unless the requested uid is "unchanged" or + * root and clearExistingCaps wasn't requested), then add back + * those in capBits + the extra ones we need to change uid/gid and + * change the capabilities bounding set. */ - capng_clear(CAPNG_SELECT_BOTH); + if (clearExistingCaps || (uid != 1 && uid != 0)) + capng_clear(CAPNG_SELECT_BOTH); for (ii = 0; ii <= CAP_LAST_CAP; ii++) { if (capBits & (1ULL << ii)) { @@ -3095,7 +3098,8 @@ cleanup: int virSetUIDGIDWithCaps(uid_t uid, gid_t gid, - unsigned long long capBits ATTRIBUTE_UNUSED) + unsigned long long capBits ATTRIBUTE_UNUSED, + bool clearExistingCaps ATTRIBUTE_UNUSED) { return virSetUIDGID(uid, gid); } diff --git a/src/util/virutil.h b/src/util/virutil.h index 2dc3403..665ad78 100644 --- a/src/util/virutil.h +++ b/src/util/virutil.h @@ -54,7 +54,8 @@ int virPipeReadUntilEOF(int outfd, int errfd, char **outbuf, char **errbuf); int virSetUIDGID(uid_t uid, gid_t gid); -int virSetUIDGIDWithCaps(uid_t uid, gid_t gid, unsigned long long capBits); +int virSetUIDGIDWithCaps(uid_t uid, gid_t gid, unsigned long long capBits, + bool clearExistingCaps); int virFileReadLimFD(int fd, int maxlen, char **buf) ATTRIBUTE_RETURN_CHECK; -- 1.8.1.4

[libvirt] [PATCH] v1:Support for adding a static route to a bridge
by Gene Czarcinski 14 Mar '13

14 Mar '13

This patch adds support for adding a static route for a network. The "via" specifies the gateway's IP address. Both IPv4 and IPv6 static routes are supported although it is expected that this functionality will have more use with IPv6. Extensive tests are done to validate that the input definitions are correct. For example, for a static route ip definition, the address must be for a network and not a host.

[libvirt] when define NAT network, assign what kind of forward dev is better
by yue 14 Mar '13

14 Mar '13

hi all: in my case, my physical machine has one ethernet, i want to use both bridge and nat network. i create a bridge outbr0(addif eth0), when creating NAT network, there are 3 options for forward-dev 1.<forward mode="nat" /> 2.<forward mode="nat" dev="outbr0"/> 3.<forward mode="nat" dev="eth0"/> i do not know which one is the best? thanks

[libvirt] Adding and Clearing bridge addresses
by Gene Czarcinski 14 Mar '13

14 Mar '13

I have been working on this patch to have libvirt optionally set static routes. So I found the function that adds both IPv4 and IPv6 addresses to the bridge in virnetdev.c. I found that besides the virNetDevAddIPv4Address() there is also virNetDevCleanIPv4Address(). I patterned my virNetDevAddGateway() after the virNetDevAddIPv4Address() function. What I am puzzled about is that it appears that nobody calls the Clear function. What don't I understand? It appears to me that the addresses and routes assigned to a bridge are all removed when the network is destroyed but otherwise remain. Gene

[libvirt] [PATCH] qemu: detect multi-head qxl via more than version check
by Eric Blake 14 Mar '13

14 Mar '13

Multi-head QXL support is so useful that distros have started to backport it to qemu earlier than 1.2. After discussion with Alon Levy, we determined that the existence of the qxl-vga.surfaces property is a reliable indicator of whether '-device qxl-vga' works, or whether we have to stick to the older '-vga qxl'. I'm leaving in the existing check for QEMU_CAPS_DEVICE_VIDEO_PRIMARY tied to qemu 1.2 and newer (in case qemu is built without qxl support), but for those distros that backport qxl, this additional capability check will allow the correct command line for both RHEL 6.3 (which lacks the feature) and RHEL 6.4 (where qemu still claims to be version 0.12.2.x, but has backported multi-head qxl). * src/qemu/qemu_capabilities.c (virQEMUCapsObjectPropsQxlVga): New property test.

Hello all, I am looking for a way to start a container with libvirt and bind multiple consoles to it. My container is running busybox, the filesystem created using the LXC package (0.8.0). My libvirt version is 0.10.1. Configuration of the filesystem: - in the container rootfs, /dev contains 2 devices - /dev/console and /dev/tty1 - the inittab file looks like this: ::sysinit:/etc/init.d/rcS tty1::respawn:/bin/getty -L tty1 115200 vt100 console::askfirst:/bin/sh - it will link the /bin/sh process to /dev/console and the /bin/getty process to /dev/tty - when starting the container with lxc-start, each of these processes gets his own local /dev/pts device: 25609 ? Ss 0:00 lxc-start -n foo -d 25612 ? Ss 0:00 \_ init 25684 ?

Is my scenario possible / supported? Thank you very much, Bogdan P. [1] http://libvirt.org/formatdomain.html#elementsConsole

[libvirt] [PATCHv6] virtio-rng: Add rate limiting options for virtio-RNG
by Peter Krempa 14 Mar '13

14 Mar '13

Qemu's implementation of virtio RNG supports rate limiting of the entropy used. This patch exposes the option to tune this functionality. This patch is based on qemu commit 904d6f588063fb5ad2b61998acdf1e73fb4 The rate limiting is exported in the XML as: <devices> ... <rng model='virtio'> <rate period='1234'>4321</rate> <backend model='random'/> </rng> ... --- Notes: Version 6: - use just attributes in XML instead of mixed attribute/contents - switch rate unit to bytes - tweak the rest to comply with the changes Version 5: - adjust after forbiding arbitrary name passthrough - rebase to master Version 4: - Reword docs - state it is available since 1.0.4 as the tree is frozen and this was actually never acked before Version 3: - State the time unit in docs Version 2: - qemu uses bytes/period, adapt the value according to that docs/formatdomain.html.in | 13 +++++++++++++ docs/schemas/domaincommon.rng | 21 ++++++++++++++++++++- src/conf/domain_conf.c | 19 +++++++++++++++++++ src/conf/domain_conf.h | 2 ++ src/qemu/qemu_command.c | 8 ++++++++ .../qemuxml2argv-virtio-rng-random.args | 2 +- .../qemuxml2argv-virtio-rng-random.xml | 1 + 7 files changed, 64 insertions(+), 2 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 35b47f2..1ef80b0 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -4294,6 +4294,7 @@ qemu-kvm -net nic,model=? /dev/null ... <devices> <rng model='virtio'> + <rate period="2000" bytes="1234"/> <backend model='random'>/dev/random</backend>  <backend model='egd' type='udp'> @@ -4316,6 +4317,18 @@ qemu-kvm -net nic,model=? /dev/null <li>'virtio' — supported by qemu and virtio-rng kernel module</li> </ul> </dd> + <dt><code>rate</code></dt> + <dd> + + The optional <code>rate</code> element allows limiting the rate at + which entropy can be consumed from the source.

[libvirt] [PATCH v7 0/3] DEVICE_DELETED event
by Michael S. Tsirkin 14 Mar '13

14 Mar '13

libvirt has a long-standing bug: when removing the device, it can request removal but does not know when the removal completes. Add an event so we can fix this in a robust way. First patch only adds the event with ID, second patch adds a path field. Split this way for ease of backport (stable downstreams without QOM would want to only take the first patch).

[libvirt] [PATCH] json: add stream parser
by Dmitry Guryanov 14 Mar '13

14 Mar '13

Add function virJSONValueFromStream, which reads data from a stream and passes it to json parser. When end of the object is reached, it returns this object. To avoid reading from the stream by single bytes it reads to a buffer (in a structure virJSONStreamParserState), which should be passed to a consequent call of this function. So if the end of one object and the beginning of the next object have been read by a single system call - virJSONValueFromStream handle it correctly. example of usage: virJSONValuePtr v; virJSONStreamParserState state; memset(&state, 0, sizeof(state)); while (1) { v = virJSONValueFromStream(mon->fd, &state); if (v == (void *)-1) /* error */ break; if (v == NULL) /* file descriptor has been closed */ break; /* handle object 'v' */ } I need such function for the parallels driver. It caches info about domains and needs some mechanism to update this cache. There is a "prlsrvctl monitor" command which waits for events forever and prints info about events to stdout in json format. So parallels driver could start separate thread which will read from prlsrvctl's stdout and update cache accordingly. There is the same task in qemu_monitor_json, but each json object is printed in a separate line there. It's not possible in my case, because some fields could have line endings.

by Daniel P. Berrange 14 Mar '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> When opening a stream to a device which is a TTY, that device may become the controlling TTY of libvirtd, if libvirtd was daemonized.

[libvirt] [PATCHv4 0/5] S390: Support for native CCW bus
by Viktor Mihajlovski 14 Mar '13

14 Mar '13

Originally, QEMU did not implement a native I/O bus for s390. The initial implementation had a machine type 's390-virtio' featuring a fully paravirtualized I/O system with an artificial bus type 'virtio-s390'. This bus had a number of short-comings, like the need for a non-standard device discovery mechanism, a limited number of devices, limited hotplugging capabilites and the lack of persistent device addresses. To resolve these issues a new machine type 's390-ccw-virtio' has been recently added to QEMU which implementa the native s390 CCW I/O bus. Guests with arch='s390x' and machine='s390-ccw-virtio' can now be defined with up to 262144 virtio devices. This series adds the support for the s390-ccw-virtio machine type and the CCW bus to libvirt. As usual we start with the documentation/schema, the generic configuration stuff, continue with the QEMU driver including device hotplug and finally add qemu2xml testcases. V2 Changes - use an attribute triple cssid, ssid, schid instead of devno to better represent the libvirt CCW address structure - rebase to current upstream, mainly address qemuCapsXXX rename V3 Changes - skip already acked patches 1/5 and 2/5 - revert machine-based capabilities - use machine definition from domain object V4 Changes - schid was technically wrong, the attribute name has to be devno: changed all occurrences accordingly - re-introduce reverted patches 1/5 and 2/5 with schid/devno correction - rebase to current upstream J.B.

[libvirt] separate module for pci passthrough device assigning and in-use tracking
by Chunyan Liu 14 Mar '13

14 Mar '13

Hi, Shradha, Laine Some time before I found you had a thread discussing in-use tracking for network and pci-passthrough devices[1], it mentioned code for tracking pci device allocation should be better as a separate module rather than a part of qemu, so that it could solve data sharing problem between hypervisor drivers and network driver. And after that, we wanted to add pci passthrough support to libxl driver[2], which turned to be the same problem, data sharing between libxl driver and other drivers, and there were code duplication between libxl and qemu driver. Laine suggested again to write code in common library as a separate module. Now I wonder if there is anyone already worked and pushed this thing to some status? If not, I am willing to try it. Thanks, Chunyan

[libvirt] [RFC PATCH 0/6] Add user namespace support for libvirt lxc
by Gao feng 14 Mar '13

14 Mar '13

This patchset try to add userns support for libvirt lxc. Since userns is nearly completed in linux-3.9, the old kernel doesn't support userns, I add some New XML elements to let people decide if enable userns.The userns is disabled by default. And because the uninit userns has no right to create devices, so we should create devices for container on host. This patch alse changes the owner of fuse and tty device. Cgroupfs is unavailable in userns now,so don't mount cgroupfs when we enable userns. Gao feng (6): LXC: New XML element for user namespace LXC: introduce virLXCControllerSetupUserns and lxcContainerSetUserns LXC: only mount cgroupfs when userns is disabled LXC: Creating devices for container on host side LXC: create tty device with proper permission for container LXC: fuse: Change files owner to the root user of container docs/formatdomain.html.in | 20 +++++- docs/schemas/domaincommon.rng | 36 ++++++++++ src/conf/domain_conf.c | 36 ++++++++++ src/conf/domain_conf.h | 21 ++++++ src/lxc/lxc_container.c | 122 ++++++++++++++++---------------- src/lxc/lxc_controller.c | 157 +++++++++++++++++++++++++++++++++++++++++- src/lxc/lxc_fuse.c | 6 ++ 7 files changed, 333 insertions(+), 65 deletions(-) -- 1.7.11.7

[libvirt] Race/broken mutex when closing a connection
by Viktor Mihajlovski 13 Mar '13

13 Mar '13

I received a report of a virsh coredump that happened on a heavy loaded system. Debugging the corefile I saw that under certain circumstances the mutex for a connection can be destroyed while another thread is waiting for the lock on that connection. Specifically this seems to happen when vshDeinit is called after the completion of vshRunCommand and at the same time the event loop is receiving a client disconnect. vshDeinit calls virConnectClose which unrefs the connection object destroying the lock mutex before releasing the memory and nulling the callback pointers. At the same time the event loop will call remoteClientCloseFunc which waits for the mutex while the connection is unrefed. It will obtain the (now invalid but non-error checking) mutex, copy the closeCallback pointer (shorty before the connection object is destroyed) and will die upon trying to call closeFreeCallback (NULL by now). First I would like to see whether someone finds an obvious flaw in my reasoning. Then I'd would like to discuss how to get around it. One thought would be to increase the refcount of the connection object in remoteClientCloseFunc before calling the closeCallback. -- Mit freundlichen Grüßen/Kind Regards Viktor Mihajlovski IBM Deutschland Research & Development GmbH Vorsitzender des Aufsichtsrats: Martina Köderitz Geschäftsführung: Dirk Wittkopp Sitz der Gesellschaft: Böblingen Registergericht: Amtsgericht Stuttgart, HRB 243294

[libvirt] [PATCHv5 0/3] DEVICE_DELETED event
by Michael S. Tsirkin 13 Mar '13

13 Mar '13

libvirt has a long-standing bug: when removing the device, it can request removal but does not know when the removal completes. Add an event so we can fix this in a robust way. First patch only adds the event for devices with ID, second path adds it for all devices and adds a path fields. Split this way for ease of backport (stable downstreams without QOM would want to only take the first patch), and also because the 2nd/3rd patches might turn out to be more controversial - if they really turn out such I'd like just the 1st one to get applied while we discuss 2 and 3. Signed-off-by: Michael S. Tsirkin <mst(a)redhat.com> Changes from v4: - Add extra triggers and extra fields as requested by Markus Changes from v3: - Document that we only emit events for devices with and ID, as suggested by Markus Changes from v2: - move event toward the end of device_unparent, so that parents are reported after their children, as suggested by Paolo Changes from v1: - move to device_unparent - address comments by Andreas and Eric -- Anthony Liguori Michael S.
