[libvirt] [PATCH] qemu: Adjust size for qcow2/qed if not on sector boundary (rewrite)
by John Ferlan 12 May '14

12 May '14

A post commit id 'e3d66229' review (and followup): http://www.redhat.com/archives/libvir-list/2014-May/msg00268.html noted some issues with the code, so I have adjusted the code accordingly. The difference between this and the commit prior to the change (commit id 'f3be5f0c') will just be the check for qcow2/qed using a non 512 block aligned size will result in a round up of size. If the size is within the last 512 bytes to ULLONG_MAX, then just set it there rather than erroring out.

[libvirt] [PATCH] util: Fix return type mismatch for nl_recv
by Wangrui (K) 12 May '14

12 May '14

1. As shown in the definition of nl_recv, its return value is of INT type. int nl_recv(struct nl_handle *handle, struct sockaddr_nl *nla, unsigned char **buf, struct ucred **creds) However, in function virNetlinkCommand, it uses an unsigned int param, respbuflen, to receive its return value. Thus, the branch "*respbuflen < 0" is unreachable, negative return values are handled incorrectly. 2. It's said in nl_recv's description that "The caller is responsible for freeing the buffer allocated * in \c *buf if a positive value is returned." which means, we needn't to free it in case it fails. Additionally, nl_recv has a BUG in handling buf: in the error branch, it frees the buf, but didn't set it to NULL. Freeing it outside in the caller function will cause double free. Thus, we set but(resp) to NULL if nl_recv fails.

[libvirt] [VHPC’14] LAST Call for Papers - Deadline in 4 weeks
by VHPC 14 12 May '14

12 May '14

================================================================= CALL FOR PAPERS 9th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '14) held in conjunction with Euro-Par 2014, August 25-29, Porto, Portugal (Springer LNCS) ================================================================= Date: August 26, 2014 Workshop URL: http://vhpc.org Paper Submission Deadline: June 9, 2014 (extended) Confirmed Keynote Speakers: Ron Brightwell, Sandia National Laboratory Hobbes: Using Virtualization to Enable Exascale Applications and Helge Meinhard, CERN CALL FOR PAPERS Virtualization technologies constitute a key enabling factor for flexible resource management in modern data centers, and particularly in cloud environments. Cloud providers need to dynamically manage complex infrastructures in a seamless fashion for varying workloads and hosted applications, independently of the customers deploying software or users submitting highly dynamic and heterogeneous workloads. Thanks to virtualization, we have the ability to manage vast computing and networking resources dynamically and close to the marginal cost of providing the services, which is unprecedented in the history of scientific and commercial computing. Various virtualization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple under-utilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization, with its capability to isolate multiple user-space environments and to allow for their co-existence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; I/O Virtualization allows physical NICs/HBAs to take traffic from multiple VMs; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology and IP addressing, provides the fundamental ground on top of which evolved network services can be realized with an unprecedented level of dynamicity and flexibility; the increasingly adopted paradigm of Software-Defined Networking (SDN) promises to extend this flexibility to the control and data planes of network paths. These technologies have to be inter-mixed and integrated in an intelligent way, to support workloads that are increasingly demanding in terms of absolute performance, responsiveness and interactivity, and have to respect well-specified Service- Level Agreements (SLAs), as needed for industrial-grade provided services. Indeed, among emerging and increasingly interesting application domains for virtualization, we can find big-data application workloads in cloud infrastructures, interactive and real-time multimedia services in the cloud, including real-time big-data streaming platforms such as used in real-time analytics supporting nowadays a plethora of application domains. Distributed cloud infrastructures promise to offer unprecedented responsiveness levels for hosted applications, but that is only possible if the underlying virtualization technologies can overcome most of the latency impairments typical of current virtualized infrastructures (e.g., far worse tail-latency). What is more, in data communications Network Function Virtualization (NFV) is becoming a key technology enabling a shift from supplying hardware-based network functions, to providing them in a software-based and elastic way. In conjunction with (public and private) cloud technologies, NFV may be used for constructing the foundation for cost-effective network functions that can easily and seamlessly adapt to demand, still keeping their major carrier-grade characteristics in terms of QoS and reliability. The Workshop on Virtualization in High-Performance Cloud Computing (VHPC) aims to bring together researchers and industrial practitioners facing the challenges posed by virtualization in order to foster discussion, collaboration, mutual exchange of knowledge and experience, enabling research to ultimately provide novel solutions for virtualized computing systems of tomorrow.

[libvirt] [RFC PATCH] Add support for invtsc timer
by Ján Tomko 12 May '14

12 May '14

Not yet merged in upstream QEMU: https://lists.gnu.org/archive/html/qemu-devel/2014-04/msg05024.html Add support for invariant TSC timer running at constant rate in all ACPI P-, C- and T-states. It can be enabled by specifying: <clock> <timer name='invtsc' present='yes'/> </clock> in the domain XML. Migration and saving the domain does not work with this timer. The support for this timer is indicated by bit 8 of EDX after calling CPUID with 0x80000007. It does not show up in /proc/cpuinfo [1] and since we're calling qemu without 'enforce', it doesn't error out if the host doesn't support this. Alternatively, we could expose it in libvirt as a cpu flag: <cpu mode='custom' match='exact'> <model fallback='forbid'>qemu64</model> <feature policy='require' name='invtsc'/> </cpu> or maybe add +invtsc to qemu args when the 'nonstop_tsc' flag is requested?

[libvirt] [PATCH] ESX: add virStorageVolGetInfo in iSCSI backend.

by Ján Tomko 08 May '14

08 May '14

Add suport for invariant TSC flag (CPUID 0x80000007, bit 8 of EDX). If this flag is enabled, the TSC ticks at a constant rate across all ACPI P-, C- and T-states. This can be enabled by adding: <feature name='invtsc'/> to the <cpu> element. Migration and saving the domain does not work with this flag. QEMU support for this is not merged yet: https://lists.gnu.org/archive/html/qemu-devel/2014-04/msg05024.html The feature name "invtsc" differs from the name "" used by the linux kernel: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/x… --- v1: https://www.redhat.com/archives/libvir-list/2014-May/msg00183.html src/cpu/cpu_map.xml | 5 +++++ src/qemu/qemu_migration.c | 14 ++++++++++++++ 2 files changed, 19 insertions(+) diff --git a/src/cpu/cpu_map.xml b/src/cpu/cpu_map.xml index 7d34d40..ffaeb92 100644 --- a/src/cpu/cpu_map.xml +++ b/src/cpu/cpu_map.xml @@ -327,6 +327,11 @@ <cpuid function='0x00000007' ebx='0x00100000'/> </feature> +  + <feature name='invtsc'> + <cpuid function='0x80000007' edx='0x00000100'/> + </feature> +  <model name='486'> <feature name='fpu'/> diff --git a/src/qemu/qemu_migration.c b/src/qemu/qemu_migration.c index a9f7fea..9ae3047 100644 --- a/src/qemu/qemu_migration.c +++ b/src/qemu/qemu_migration.c @@ -1513,6 +1513,20 @@ qemuMigrationIsAllowed(virQEMUDriverPtr driver, virDomainObjPtr vm, return false; } + for (i = 0; i < def->cpu->nfeatures; i++) { + virCPUFeatureDefPtr feature = &def->cpu->features[i]; + + if (feature->policy != VIR_CPU_FEATURE_REQUIRE) + continue; + + if (STREQ(feature->name, "invtsc")) { + virReportError(VIR_ERR_OPERATION_INVALID, + _("domain has CPU feature: %s"), + feature->name); + return false; + } + } + return true; } -- 1.8.3.2

[libvirt] [PATCH] qemu: Adjust size for qcow2/qed if not on sector boundary
by John Ferlan 08 May '14

08 May '14

https://bugzilla.redhat.com/show_bug.cgi?id=1002813 If qemuDomainBlockResize() is passed a size not on a KiB boundary - that is passed a size based in bytes (VIR_DOMAIN_BLOCK_RESIZE_BYTES), then depending on the source format (qcow2 or qed), the value passed must be on a sector (or 512 byte) boundary. Since other libvirt code quietly adjusts the capacity values, then do so here as well - of course ensuring that adjustment still fits.

[libvirt] [PATCH] LXC: don't doubly link /dev/console
by Dwight Engen 07 May '14

07 May '14

When a console is configured, /dev/console and /dev/tty1 are created as symlinks to the same underlying pts. This causes problems since a separate getty will be spawned for /dev/console and /dev/tty1, but they are each controlling the same device. This patch makes it so that /dev/console is the sole symlink to the first console, /dev/tty1 to the second, /dev/tty2 to the third and so on.

Hello, I'd like to continue working on the parallels driver. So here is a set of patches, which resolves some problems. Now Parallels has a definite goal with this driver: we want OpenStack to be working with Parallels Cloud Server (PCS) over libvirt, and we a ready to implement all needed API calls in libvirt's driver and make necessary changes in PCS.

Additionally a preexisting condition where if deleteVol didn't exist or failed, the volume would not be removed from volumes.objs[] even though it doesn't exist. This results in virsh vol-list and vol-info not finding the volume and emitting error messages.

[libvirt] [question]qemu: migrate and destory vm immediately on destination causes libvirt deadlock or segment fault
by Wangrui (K) 07 May '14

07 May '14

Hi everyone, I do ram migration operation in KVM environment(libvirt1.2.4 qemu1.5.1). I encountered libvirtd deadlock or segmentfault when I destroy the migration VM on destination. I got the problem by flowing steps: step 1: migrate VM. step 2: execute "virsh destroy [VMName]" to destroy the migration VM on destination immediately. step 3: the destination libvirtd will be probably deadlock or segmentfault. Deadlock stack as followed: #0 0x00007fb5c18132d4 in __lll_lock_wait () from /lib64/libpthread.so.0 #1 0x00007fb5c180e659 in _L_lock_1008 () from /lib64/libpthread.so.0 #2 0x00007fb5c180e46e in pthread_mutex_lock () from /lib64/libpthread.so.0 #3 0x00007fb5c45d175f in virMutexLock (m=0x7fb5b0066ed0) at util/virthread.c:88 #4 0x00007fb5c45b6b04 in virObjectLock (anyobj=0x7fb5b0066ec0) at util/virobject.c:323 #5 0x00007fb5b8f4842a in qemuMonitorEmitEvent (mon=0x7fb5b0066ec0, event=0x7fb5b00688d0 "SHUTDOWN", seconds=1399374472, micros=509994, details=0x0) at qemu/qemu_monitor.c:1185 #6 0x00007fb5b8f62af2 in qemuMonitorJSONIOProcessEvent (mon=0x7fb5b0066ec0, obj=0x7fb5b0069080) at qemu/qemu_monitor_json.c:158 #7 0x00007fb5b8f62d25 in qemuMonitorJSONIOProcessLine (mon=0x7fb5b0066ec0, line=0x7fb5b005bbe0 "{\"timestamp\": {\"seconds\": 1399374472, \"microseconds\": 509994}, \"event\": \"SHUTDOWN\"}",msg=0x7fb5bd873c80) at qemu/qemu_monitor_json.c:195 #8 0x00007fb5b8f62f85 in qemuMonitorJSONIOProcess (mon=0x7fb5b0066ec0, data=0x7fb5b0060770 "{\"timestamp\": {\"seconds\": 1399374472, \"microseconds\": 509994},\"event\": \"SHUTDOWN\"}\r\n", len=85, msg=0x7fb5bd873c80) at qemu/qemu_monitor_json.c:237 #9 0x00007fb5b8f49aa0 in qemuMonitorIOProcess (mon=0x7fb5b0066ec0) at qemu/qemu_monitor.c:402 #10 0x00007fb5b8f4a09b in qemuMonitorIO (watch=20, fd=24, events=0, opaque=0x7fb5b0066ec0) at qemu/qemu_monitor.c:651 #11 0x00007fb5c458c4d9 in virEventPollDispatchHandles (nfds=17, fds=0x7fb5b0068a60) at util/vireventpoll.c:510 #12 0x00007fb5c458decf in virEventPollRunOnce () at util/vireventpoll.c:659 #13 0x00007fb5c458bfcc in virEventRunDefaultImpl () at util/virevent.c:308 #14 0x00007fb5c51a17a9 in virNetServerRun (srv=0x7fb5c5411d70) at rpc/virnetserver.c:1139 #15 0x00007fb5c5157f63 in main (argc=3, argv=0x7fff7fc04f48) at libvirtd.c:150 After analysis, I found it may be caused by multithreaded simultaneously access to the global variables "vm->privateData->mon". When problems occur，there are three libvirtd threads at work on destination host，suppose： ThreadA: migration thread，do qemuProcessStart. ThreadB: destroy thread，do qemuDoaminDestroy -> qemuProcessStop. ThreadC：Monitor Thread，do IOWrite、IORead and some other operations according to the mon->msg when mon->fd change. When threadB destroy happpens, this thread would handle the SUHTDOWN event. In threadA, when it sends QMP command to Qemu, it will operate the vm->privateData->mon lock. Such as the operation "qemuDomainObjEnterMonitor -> qemuMonitorSetBalloon -> qemuDomainObjExitMonitor", but it's not an atomic operation. If "virsh destroy [VMName]" happens during this operation, threadB will set the lock vm->privateData->mon to NULL in qemuProcessStop. And then in threadA, the function qemuDomainObjExitMonitor will fail to unlock vm->privateData->mon as it's NULL. So, threadC will never acquire the vm->privateData->mon lock and the deadlock problem happened. what was worse, if qemuMonitorSetBalloon perform succeed in threadA. ThreadA will coutinue to execute till it enter the function qemuMonitorSetDomainLog, it would cause segmentfault at VIR_FORCE_CLOSE(mon->logfd) due to mon is NULL. I could not find a good way to sovle this problem. Does anyone have good ideas? Thanks. Ps: I find an easy way to reproduce this problem more probably by following steps: step 1: Fault Injection, fit into this patch and update the libvirtd on destination host: --- src/qemu/qemu_process.c 2014-05-06 19:06:00.000000000 +0800 +++ src/qemu/qemu_process.c 2014-05-06 19:07:12.000000000 +0800 @@ -4131,6 +4131,8 @@ vm->def->mem.cur_balloon); goto cleanup; } + VIR_DEBUG("Fault Injection, sleep 3 seconds."); + sleep(3); qemuDomainObjEnterMonitor(driver, vm); if (vm->def->memballoon && vm->def->memballoon->period) qemuMonitorSetMemoryStatsPeriod(priv->mon, vm->def->memballoon->period); step 2: migrate VM. step 3: execute "virsh destroy [VMName]" to destroy the migration VM on destination when log prints "Fault Injection, sleep 3 seconds." step 4: the libvirtd deadlock stack occurs as above mentioned.

[libvirt] [libvirt PATCH] udev: consider the device a CDROM when ID_CDROM=1
by Giuseppe Scrivano 07 May '14

07 May '14

Some CDROM devices are reported by udev to have an ID_TYPE="generic" thus it is necessary to check if ID_CDROM is present. As a side effect, treating ID_TYPE="generic" as a missing ID_TYPE will enable checks for ID_DRIVE_FLASH_SD and ID_DRIVE_FLOPPY and the udevKludgeStorageType heuristic.

[libvirt] [PATCH] PCI: Introduce new device binding path using pci_dev.driver_override
by Alex Williamson 06 May '14

06 May '14

The driver_override field allows us to specify the driver for a device rather than relying on the driver to provide a positive match of the device. This shortcuts the existing process of looking up the vendor and device ID, adding them to the driver new_id, binding the device, then removing the ID, but it also provides a couple advantages. First, the above existing process allows the driver to bind to any device matching the new_id for the window where it's enabled. This is often not desired, such as the case of trying to bind a single device to a meta driver like pci-stub or vfio-pci. Using driver_override we can do this deterministically using: echo pci-stub > /sys/bus/pci/devices/0000:03:00.0/driver_override echo 0000:03:00.0 > /sys/bus/pci/devices/0000:03:00.0/driver/unbind echo 0000:03:00.0 > /sys/bus/pci/drivers_probe Previously we could not invoke drivers_probe after adding a device to new_id for a driver as we get non-deterministic behavior whether the driver we intend or the standard driver will claim the device. Now it becomes a deterministic process, only the driver matching driver_override will probe the device. To return the device to the standard driver, we simply clear the driver_override and reprobe the device: echo > /sys/bus/pci/devices/0000:03:00.0/preferred_driver echo 0000:03:00.0 > /sys/bus/pci/devices/0000:03:00.0/driver/unbind echo 0000:03:00.0 > /sys/bus/pci/drivers_probe Another advantage to this approach is that we can specify a driver override to force a specific binding or prevent any binding. For instance when an IOMMU group is exposed to userspace through VFIO we require that all devices within that group are owned by VFIO. However, devices can be hot-added into an IOMMU group, in which case we want to prevent the device from binding to any driver (preferred driver = "none") or perhaps have it automatically bind to vfio-pci. With driver_override it's a simple matter for this field to be set internally when the device is first discovered to prevent driver matches. Signed-off-by: Alex Williamson <alex.williamson(a)redhat.com> --- Changes since RFC: - Add ABI documentation (gregkh) - Documentation wording clarification (Christoffer) Nobody puked on the RFC and platform folks have posted a working version of this for platform devices, so I guess the only thing left to do is formally propose this as a new driver binding mechanism. I don't see much incentive to push this into the driver core since the match ultimately needs to be done by the bus driver. I think this is therefore like new_id/remove_id where PCI and USB implement separate, but consistent interfaces. I've pruned the CC list a bit from the RFC, but I've added libvirt folks since I expect they would be the first userspace tool that would adopt this.

[libvirt] LSN-2014-0003: Unsafe parsing of XML documents allows arbitrary file read
by Daniel P. Berrange 06 May '14

06 May '14

Libvirt Security Notice: LSN-2014-0003 ====================================== Summary: Unsafe parsing of XML documents allows arbitrary file read Reported on: 20140411 Published on: 20140506 Fixed on: 20140506 Reported by: Daniel P. Berrange <berrange(a)redhat.com> Richard Jones <rjones(a)redhat.com> Patched by: Daniel P. Berrange <berrange(a)redhat.com> See also: CVE-2014-0179 Description ----------- When parsing XML documents, libvirt passes the XML_PARSE_NOENT flag to libxml2 which instructs it to expand all entities in the XML document during parsing. This can be used to insert the contents of host OS files in the resulting parsed content. Although the flaw was introduced in 0.0.5, it was dormant having no ill effects, since the APIs involved all required the user to authenticate with privileges equivalent to root. In version 0.7.5 or later the virConnectCompareCPU / virConnectBaselineCPU methods activate the dormant bug, allowing for denial of service. In version 1.0.0 or later, if the admin opts in to using the new fine grained access control feature, there is potential for unprivileged information disclosure. Impact ------ A malicious user can pass libvirt an XML document which contains an entity that points to an arbitrary file on the host. When libvirt parses this document, it will insert the contents of that host file, which could allow the user to read the contents of files that they otherwise do not have permission to view. It also has the potential to cause a denial of service / indefinite hang of libvirt, if the entity points to a named pipe with no writer connected or certain proc files. If the libvirt installation is not using fine grained access control then virConnectCompareCPU and virConnectBaselineCPU APIs can be used by a read-only user to inflict a denial of service attack. If the libvirt installation is using fine grained access control, then as well as the denial of service attack, one or more of the following APIs can be used for information disclosure of files: virDomainDefineXML, virNetworkCreateXML, virNetworkDefineXML, virStoragePoolCreateXML, virStoragePoolDefineXML, virStorageVolCreateXML, virDomainCreateXML, virNodeDeviceCreateXML, virInterfaceDefineXML, virStorageVolCreateXMLFrom, virConnectDomainXMLFromNative, virConnectDomainXMLToNative, virSecretDefineXML, virNWFilterDefineXML, virDomainSnapshotCreateXML, virDomainSaveImageDefineXML, virDomainCreateXMLWithFiles, virConnectCompareCPU, virConnectBaselineCPU. Workaround ---------- Stop use of the fine grained access control mechanism, and restrict access to all the libvirt TCP/UNIX sockets to only trusted authenticated users. Simply denying access to the affected APIs in the access control policy is insufficient to mitigate the bug, since the XML document typically needs to be parsed before the access control check is applied in order to extra the UUID/name of the object to check. Access to the readonly libvirt socket must also be revoked Affected product ---------------- Name: libvirt Repository: git://libvirt.org/git/libvirt.git http://libvirt.org/git/?p=libvirt.git Branch:

[libvirt] [PATCH] util: changing all the "enum" structures into typedef's in "src/util/" directory.
by Julio Faracco 06 May '14

06 May '14

In "src/util/" there are many enumeration (enum) structures. Sometimes, it's better using a typedef for variable types, function types and other usages. Other enumeration will be changed to typedef's in the future.

[libvirt] [PATCH 1/5] conf: changing all the "enum" structures into typedef's in "src/conf/" directory.
by Julio Faracco 06 May '14

06 May '14

In "src/conf/" there are many enumeration (enum) structures like "src/util" directory. Sometimes, it's better using a typedef for variable types, function types and other usages. Other enumeration and folders will be changed to typedef's in the future. Most of the files changed in this commit included CPU (cpu_conf) enum structures.

To whom it may concern, I’m just beginning to use the libvirt suite of tools and, in going through your wiki, I’ve found a couple of minor things (mostly typos) that I would immediately correct. Also, if I get my project up, I may be able to provide some less-trivial examples of network setup xml as well. Please feel free to NOT forward this email after moderation as it will likely be of little interest to the group at large. ;-) Thanks, Jim Thornsberry

[libvirt] [PATCH v3 0/3] bhyve: implement PCI address allocation
by Roman Bogorodskiy 06 May '14

06 May '14

The first attempt to share PCI allocation code from qemu driver with bhyve. To this point it went pretty smooth and I didn't have to make any changes to the implementation of the extracted PCI code. The only slight change I made is extracing virDomainPCIAddressSetAlloc() from DomainPCIAddressSetCreate() to perform the actual memory allocation, just because having virDomainPCIAddressSetFree() without Alloc() felt a little inconsistent. During testing I spotted only one problem (so far): the domain defined on libvirtd without new PCI allocation doesn't start on a new version because the definition didn't have addresses auto-assigned.

[libvirt] libvirt 1.2.4 and virt-manager 0.9.0 are not incompatible
by xeon_feng 06 May '14

06 May '14

Hello everyone I encountered a problem when I completed the update of libvirt from 0.10 to 1.2.4 . The problem was that virt-manager(version 0.9.0) could not start and reported error : "ImportError: /usr/lib64/libvirt.so.0: version 'LIBVIRT_PRIVIATE_0.10.2' not found (required by /usr/lib64/python2.6/site-packages/libvirtmod.so)". I found the libvirt.so.0 link file just in the /usr/lib64/ directory , but it was linking to libvirt.so.0.1002.4 .not to the libvirt.so.0.10.2 I made libvirt.so.0 to link to libvirt.so.0.10.2 and restarted virt-manager , virt-manager started normally then restarted libvirtd failure, reporting error:l “ibvirtd: /usr/lib64/libvirt.so.0: version 'LIBVIRT_1.2.3' not found (require by libvirtd) .....” I made libvirt.so.0 to link to libvirt.so.0.1002.4 and restart libvirtd , libvirtd started normally again. Please help me to resolve the problem and give me some advise.... Thanks a lot.. Xeon.Feng

[libvirt] Question about QCOW2 and Libvirt Storage Pools
by Solly Ross 05 May '14

05 May '14

Hi, I'm doing some work getting libvirt storage pools into OpenStack, as they definitely make certain operations much easier for the Nova libvirt driver. However, one thing I noticed is that since storage pools automatically refresh on reboot, initial creation information gets lost. This poses a problem, since libvirt probes for file type for the filesystem-based pools (dir, fs, netfs, etc), and can erroneously detect a RAW file as another file type (for instance, QCOW2). Is there a reason libvirt doesn't have an option to persist (to disk) the unchanging parts of the volume XML? Best Regards, Solly Ross P.S. we currently deal with a similar problem in OpenStack by saving the file type to disk the first time we use the image file. However, it would be nice if libvirt could handle this for us, at some point, as it seems like it would be a good thing to have in libvirt.

[libvirt] [PATCH v3] storageVolCreateXMLFrom: Allow multiple accesses to origvol
by Michal Privoznik 05 May '14

05 May '14

When creating a new volume, it is possible to copy data into it from another already existing volume (referred to as @origvol). Obviously, the read-only access to @origvol is required, which is thread safe (probably not performance-wise though). However, with current code both @newvol and @origvol are marked as building for the time of copying data from the @origvol to @newvol. The rationale behind is to disallow some operations on both @origvol and @newvol, e.g. vol-wipe, vol-delete, vol-download. While it makes sense to not allow such operations on partly copied mirror, but it doesn't make sense to disallow vol-create on the source (@origvol).

[libvirt] CPU type/flags when converting a physical machine to run on libvirt
by Richard W.M. Jones 03 May '14

03 May '14

I'm in the process of rewriting virt-p2v which is our program for converting physical machines to become virtual machines, running on top of libvirt + KVM. The physical machine has certain characteristics -- eg: - number of physical cores - amount of RAM - CPU type (eg. AMD Opteron, Intel Core i7) - CPU flags (eg. ACPI, SSE4) which it might make sense to reflect in the libvirt XML of the virtual machine we create. The old version of virt-p2v is pretty simplistic about this. It generates *only* an i386 or x86-64 VM, and the only flags it considers are 'apic', 'acpi', 'pae' and 'lm' [the latter to distinguish between 32 and 64 bit x86]. What should the new version do? Particular questions: - Should we try to reflect the CPU type of the physical machine in the virtual machine? eg. If it's an Opteron, we generate an Opteron target machine. (I believe the answer is *no*, because this is not live migration, and most guests can boot on any compatible CPU). - How can I ask libvirt to give me the best possible CPU, and not some baseline? Normally I use host-model, but I think that prevents migration. - What CPU flags should be reflected in the target libvirt XML? - Is it worth modelling CPU thread layout? (I suspect this will be a lot of work with the potential to break things rather than provide any measurable benefits.) - Is there anything else I haven't thought about? However the overriding rule is: - We *must not* end up with a target virtual machine which doesn't work! Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-p2v converts physical machines to virtual machines.

[libvirt] qemu: managedsave vs. save
by Richard Weinberger 02 May '14

02 May '14

Hi! My KVM hosts share the same filesystem and I'm facing an issue using managedsave. If I save vmX using managedsave on hostA and restore it later using "virsh restore" in hostB the qemu process consumes 100% CPU and makes no progress. On the other hand, if I save vmX using save the restore works fine on hostB. Why can't I restore vms saved by managedsave using restore? Or is this a known issue on libvirt-0.10.X (CentOS 6)? -- Thanks, //richard

[libvirt] [PATCHv2] storageVolCreateXMLFrom: Allow multiple accesses to origvol
by Michal Privoznik 02 May '14

02 May '14

When creating a new volume, it is possible to copy data into it from another already existing volume (referred to as @origvol). Obviously, the read-only access to @origvol is required, which is thread safe (probably not performance-wise though). However, with current code both @newvol and @origvol are marked as building for the time of copying data from the @origvol to @newvol. The rationale behind is to disallow some operations on both @origvol and @newvol, e.g. vol-wipe, vol-delete, vol-download. While it makes sense to not allow such operations on partly copied mirror, but it doesn't make sense to disallow the operations on the source (@origvol).

[libvirt] [PATCH] Restore skipping of setting capacity
by John Ferlan 02 May '14

02 May '14

Commit id 'ac9a0963' refactored out the 'withCapacity' for the virStorageBackendUpdateVolInfo() API. See: http://www.redhat.com/archives/libvir-list/2014-April/msg00043.html This resulted in a difference in how 'virsh vol-info --pool <poolName> <volume>' or 'virsh vol-list vol-list --pool <poolName> --details' outputs the capacity information for a directory pool with a qcow2 sparse file. For example, using the following XML mkdir /home/TestPool cat testpool.xml <pool type='dir'> <name>TestPool</name> <uuid>6bf80895-10b6-75a6-6059-89fdea2aefb7</uuid> <source> </source> <target> <path>/home/TestPool</path> <permissions> <mode>0755</mode> <owner>0</owner> <group>0</group> </permissions> </target> </pool> virsh pool-create testpool.xml virsh vol-create-as --pool TestPool temp_vol_1 \ --capacity 1048576 --allocation 1048576 --format qcow2 virsh vol-info --pool TestPool temp_vol_1 Results in listing a Capacity value. Prior to the commit, the value would be '1.0 MiB' (1048576 bytes). However, after the commit the output would be (for example) '192.50 KiB', which for my system was the size of the volume in my file system (eg 'ls -l TestPool/temp_vol_1' results in '197120' bytes or 192.50 KiB). While perhaps technically correct, it's not necessarily what the user expected (certainly virt-test didn't expect it).

[libvirt] [PATCH] tests: don't fail with newer gnutls
by Martin Kletzander 02 May '14

02 May '14

gnutls-3.3.0 and newer leaves 2 FDs open in order to be backwards compatible when it comes to chrooted binaries [1]. Linking commandhelper with gnutls then leaves these two FDs open and commandtest fails thanks to that. This patch does not link commandhelper with libvirt.la, but rather only the utilities making the test pass. Based on suggestion from Daniel [2].

We are seeing issues(data is unavailable) with usage of the following Libvirt APIs, on RHEL5, while they are working Ok with RHEL 6, SLES10/11. CPU dumpxml from Domain.getXMLDesc() returns no xml nodes for CPU model and topology and its sub-elements such as sockets, cores, threads. Domain.memoryStats(int) : added since 0.5.0 Please guide.

[libvirt] Test failures with newest gnutls
by Martin Kletzander 01 May '14

01 May '14

Hi everyone, after upgrade to gnutls-3.3.0, I discovered (commandtest fails) that any code linked with -lgnutls will have not 3, but 5 open file descriptors upon the entry into main(). I asked on gnutls-help [1] if they know they are leaking file descriptors. The response was, that this is intended with the explanation being that these FDs (pointing to /dev/urandom) are kept open for backward compatibility with programs that may chroot into environment without /dev/urandom as the previous version didn't require to have access to /dev/urandom when calling gnutls code. Does that seem like our bug that we're relying on fixed number of open file descriptors? Or that we're linking to gnutls when we don't need it in commandhelper? Or should this be fixed somewhere else? Have a nice day, Martin [1] http://lists.gnutls.org/pipermail/gnutls-help/2014-April/003415.html

[libvirt] [PATCH] php: implement libvirt_node_get_free_memory.
by Dawid Zamirski 01 May '14

01 May '14

This patch adds support for virNodeGetFreeMemory which is available in libvirt since v0.3.3. While the php bindings alredy provide libvirt_node_get_mem_stats from which such info could be obtained, not all hypervisors support it, e.g. vbox and esx driver don't have it but they do implement virNodeGetFreeMemory. Since virNodeGetFreeMemory returns free bytes as unsigned long long which PHP cannot handle, I've added LONGLONG_RETURN_AS_STRING macro which returns the amount bytes as a string - similarly to how bcmath handles such numbers. --- src/libvirt-php.c | 30 ++++++++++++++++++++++++++++++ src/libvirt-php.h | 1 + 2 files changed, 31 insertions(+) diff --git a/src/libvirt-php.c b/src/libvirt-php.c index 07ae137..94a0c6b 100644 --- a/src/libvirt-php.c +++ b/src/libvirt-php.c @@ -198,6 +198,7 @@ static zend_function_entry libvirt_functions[] = { PHP_FE(libvirt_node_get_cpu_stats, NULL) PHP_FE(libvirt_node_get_cpu_stats_for_each_cpu, NULL) PHP_FE(libvirt_node_get_mem_stats, NULL) + PHP_FE(libvirt_node_get_free_memory, NULL) /* Nodedev functions */ PHP_FE(libvirt_nodedev_get, NULL) PHP_FE(libvirt_nodedev_capabilities, NULL) @@ -1428,6 +1429,11 @@ str_out = estrndup(str_in, strlen(str_in)); \ add_index_long(out, key,in); \ } +#define LONGLONG_RETURN_AS_STRING(in) \ + snprintf(tmpnumber, 63, "%llu", in); \ + RETURN_STRING(tmpnumber, 1); + + /* Authentication callback function.

[libvirt] [PATCH v6 0/6] Expose FSFreeze/FSThaw within the guest as API
by Tomoki Sekiyama 01 May '14

01 May '14

Hello, This is patchset v6 to add FSFreeze/FSThaw API for custom disk snapshotting. Changes since v5: * replace disks and ndisks parameter with mountpoints and nmountpoints to specify filesystem to be frozen/thawed, so that we can specify non-disk-backed filesystems * add PATCH 6 to support 'mountpoints' argument for 'guest-fsfreeze-freeze' command of qemu-guest-agent. (This requires a patch for qemu-guest-agent, which isn't merged yet: https://lists.gnu.org/archive/html/qemu-devel/2014-04/msg04434.html ) * drop nested fsfreeze request feature * change API version to 1.2.5 (v5: https://www.redhat.com/archives/libvir-list/2014-April/msg00140.html ) === Description === Currently FSFreeze and FSThaw are supported by qemu guest agent and they are used internally in snapshot-create command with --quiesce option. However, when users want to utilize the native snapshot feature of storage devices (such as LVM over iSCSI, enterprise storage appliances, etc.), they need to issue fsfreeze command separately from libvirt-driven snapshots. (OpenStack cinder provides these storages' snapshot feature, but it cannot quiesce the guest filesystems automatically for now.) Although virDomainQemuGuestAgent() API could be used for this purpose, it is only for debugging and is not supported officially. This patchset adds virDomainFSFreeze()/virDomainFSThaw() APIs and virsh domfsfreeze/domfsthaw commands to enable the users to freeze and thaw domain's filesystems cleanly. <updated> The APIs take disks and ndisks parameters, which is a list of mountpoints of filesystems to be frozen/thawed. If the option is not provided, or guest agent doesn't support the 'mountpoints' argument, every mounted filesystem is frozen/thawed. </updated> The APIs have flags option currently unsupported for future extension. --- Tomoki Sekiyama (6): Introduce virDomainFSFreeze() and virDomainFSThaw() public API remote: Implement virDomainFSFreeze and virDomainFSThaw qemu: track quiesced status in qemuDomainSnapshotFSFreeze qemu: Implement virDomainFSFreeze and virDomainFSThaw virsh: Expose new virDomainFSFreeze and virDomainFSThaw API qemu: Support mountpoints option of guest-fsfreeze-freeze include/libvirt/libvirt.h.in | 10 +++ src/access/viraccessperm.c | 2 - src/access/viraccessperm.h | 6 ++ src/driver.h | 14 ++++ src/libvirt.c | 93 ++++++++++++++++++++++++ src/libvirt_public.syms | 6 ++ src/qemu/qemu_agent.c | 47 +++++++++++- src/qemu/qemu_agent.h | 3 + src/qemu/qemu_domain.c | 5 + src/qemu/qemu_domain.h | 2 + src/qemu/qemu_driver.c | 160 ++++++++++++++++++++++++++++++++++++++---- src/remote/remote_driver.c | 2 + src/remote/remote_protocol.x | 38 +++++++++- src/remote_protocol-structs | 18 +++++ src/rpc/gendispatch.pl | 2 + tests/qemuagenttest.c | 8 +- tools/virsh-domain.c | 130 ++++++++++++++++++++++++++++++++++ tools/virsh.pod | 23 ++++++ 18 files changed, 544 insertions(+), 25 deletions(-)

[libvirt] [PATCH] qemu: fix crash when removing <filterref> from interface with update-device
by Laine Stump 01 May '14

01 May '14

If a domain network interface that contains a <filterref> is modified "live" using "virsh update-device --live", libvirtd would crash. This was because the code supporting live update of an interface's filterref was assuming that a filterref might be added or modified, but didn't account for removing the filterref, resulting in a null dereference of the filter name. Introduced with commit 258fb278, which was first in libvirt v1.0.1.

[libvirt] [PATCH v7 0/4] Handling of undefine and re define snapshots with VirtualBox 4.2 or higher
by Yohan BELLEGUIC 01 May '14

01 May '14

Hello, This is a new series of patches in order to support undefining and redefining snapshots with VirtualBox 4.2 or higher. These patches are based on Manuel Vives' patches, taking into account Daniel P. Berrange's remarks. The VirtualBox API provides only high level operations to manipulate snapshots, so it not possible to support flags like VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and VIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY with only API calls. Following an IRC talk with Eric Blake, the decision was made to emulate these behaviours by manipulating directly the .vbox XML files. The first patch adds extra details in the snapshot XML returned by libvirt. We will need those details in order to redefine the snapshots. The second patch adds a new API to manipulate the VirtualBox XML file. It provides several structs describing the VirtualBox XML file nodes and functions which can manipulate these structs. The third patch adds support of the VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and VIR_DOMAIN_SNAPSHOT_CREATE_CURRENT flags in virDomainSnapshotCreateXML. The idea is to unregister the machine, add the snapshot in the Virtualbox XML file and re-register the machine. However, VirtualBox forbids a machine to have snapshots but no current snapshot. So, if the real current snapshot has not been redefined yet, we create fake disks, allowing us to have an intermediate state in order to not corrupt the snapshot's read-write disks. These fake disks will be deleted during the next redefine. The fourth and last patch adds support of the VIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY flag in virDomainSnapshotDelete. As in the third patch, we also create fake disks to not corrupt the snapshot's read-write disks. The patches were only tested with VirtualBox 4.3.10 and VirtualBox 4.2.24. Regards Yohan BELLEGUIC v7: * Add vbox_snapshot_conf.{h,c} files to (de)serialize VirtualBox XML files * Update the code to use the API exposed by vbox_snapshot_conf.h * Handle the fact that VirtualBox forbids a machine to have snapshots but no current snapshot v6: * Rebased because of a massive change in vbox_tmpl.c due to changes in the handling of different versions of VirtualBox v5: * The patches are modified according to a first review by Laine Stump: * renamed virSearchUuid to virSearchRegex and moved it from viruuid.{c,h} to virstring.{c,h}. * Various fixes. v4: * The code is compliant with Virtualbox 4.3 API * Some minor modifications in order to satisfy "make syntax-check" v3: * Use of STREQ_NULLABLE instead of STREQ in one case * Fix the method for finding uuids according to Ján Tomko review v2: * Fix a licence problem with the method for string replacement Manuel VIVES (1): vbox_tmpl.c: Better XML description for snapshots Yohan BELLEGUIC (3): Add vbox_snapshot_conf struct vbox_tmpl.c: Patch for redefining snapshots vbox_tmpl.c: Add function for undefining snapshot po/POTFILES.in | 1 + src/Makefile.am | 1 + src/vbox/vbox_snapshot_conf.c | 1383 +++++++++++++++++++++++++ src/vbox/vbox_snapshot_conf.h | 100 ++ src/vbox/vbox_tmpl.c | 2225 +++++++++++++++++++++++++++++++++++++---- 5 files changed, 3538 insertions(+), 172 deletions(-) create mode 100644 src/vbox/vbox_snapshot_conf.c create mode 100644 src/vbox/vbox_snapshot_conf.h -- 1.7.10.4

[libvirt] [PATCH] conf: handle 'vda[-1]' uniformly
by Eric Blake 01 May '14

01 May '14

Commit f22b7899 stumbled across a difference between 32-bit and 64-bit platforms; on 64-bit, parsing "-1" as a long produces 0xffffffffffffffff, which does not fit in unsigned int; but on 32-bit, it parses as 0xffffffff, which DOES fit. Another patch will tweak virStrToLong_ui to behave the same across platforms, but regardless of which of the two choices it makes, the chain lookup code wants to reject negative numbers rather than treating it as large integers. * src/util/virstoragefile.c (virStorageFileParseChainIndex): Reject negative sign. Signed-off-by: Eric Blake <eblake(a)redhat.com> --- Therefore, although this qualifies as a build-breaker fix on 32-bit, I haven't pushed it yet: I'm still working on my patch to virstring.c for uniform behavior; and that turned up the fact that virstringtest.c doesn't have coverage of integer parsing, so of course, I have to expand that test too... src/util/virstoragefile.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/src/util/virstoragefile.c b/src/util/virstoragefile.c index dcce1ef..5d933a4 100644 --- a/src/util/virstoragefile.c +++ b/src/util/virstoragefile.c @@ -1525,7 +1525,9 @@ virStorageFileParseChainIndex(const char *diskTarget, if (virStringListLength(strings) != 2) goto cleanup; - if (virStrToLong_ui(strings[1], &suffix, 10, &idx) < 0 || + /* Rule out spaces or negative sign */ + if (!c_isdigit(*strings[1]) || + virStrToLong_ui(strings[1], &suffix, 10, &idx) < 0 || STRNEQ(suffix, "]")) goto cleanup; -- 1.9.0

by Stefan Berger 30 Apr '14

30 Apr '14

From: Stefan Berger <stefanb(a)linux.vnet.ibm.com> An IP or IPv6 rule with port specification but without protocol specification cannot be instantiated by ebtables. The documentation points to 'protocol' being required but implementation does not enforce it to be given. Implement a rule validation function that checks whether the rule is valid when it is defined. This for example prevents the definition of rules like: <ip dstportstart='53'> where a protocol attribute would be required for it to be valid and for ebtables to be able to instantiate it.

[libvirt] [PATCH V5] libxl: add migration support
by Jim Fehlig 30 Apr '14

30 Apr '14

This patch adds initial migration support to the libxl driver, using the VIR_DRV_FEATURE_MIGRATION_PARAMS family of migration functions. Signed-off-by: Jim Fehlig <jfehlig(a)suse.com> --- V4 here https://www.redhat.com/archives/libvir-list/2014-April/msg01070.html In V5: Use libvirt's V3 migration protocol for handshake and control instead of duplicating that in the libxl driver. po/POTFILES.in | 1 + src/Makefile.am | 3 +- src/libxl/libxl_conf.h | 6 + src/libxl/libxl_domain.h | 1 + src/libxl/libxl_driver.c | 235 +++++++++++++++++++ src/libxl/libxl_migration.c | 544 ++++++++++++++++++++++++++++++++++++++++++++ src/libxl/libxl_migration.h | 78 +++++++ 7 files changed, 867 insertions(+), 1 deletion(-) diff --git a/po/POTFILES.in b/po/POTFILES.in index e35eb82..a72dc1e 100644 --- a/po/POTFILES.in +++ b/po/POTFILES.in @@ -73,6 +73,7 @@ src/lxc/lxc_process.c src/libxl/libxl_domain.c src/libxl/libxl_driver.c src/libxl/libxl_conf.c +src/libxl/libxl_migration.c src/network/bridge_driver.c src/network/bridge_driver_linux.c src/node_device/node_device_driver.c diff --git a/src/Makefile.am b/src/Makefile.am index e9dc9e0..0dbda7f 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -706,7 +706,8 @@ XENAPI_DRIVER_SOURCES = \ LIBXL_DRIVER_SOURCES = \ libxl/libxl_conf.c libxl/libxl_conf.h \ libxl/libxl_domain.c libxl/libxl_domain.h \ - libxl/libxl_driver.c libxl/libxl_driver.h + libxl/libxl_driver.c libxl/libxl_driver.h \ + libxl/libxl_migration.c libxl/libxl_migration.h UML_DRIVER_SOURCES = \ uml/uml_conf.c uml/uml_conf.h \ diff --git a/src/libxl/libxl_conf.h b/src/libxl/libxl_conf.h index 24e1720..b798567 100644 --- a/src/libxl/libxl_conf.h +++ b/src/libxl/libxl_conf.h @@ -43,6 +43,9 @@ # define LIBXL_VNC_PORT_MIN 5900 # define LIBXL_VNC_PORT_MAX 65535 +# define LIBXL_MIGRATION_PORT_MIN 49152 +# define LIBXL_MIGRATION_PORT_MAX 49216 + # define LIBXL_CONFIG_DIR SYSCONFDIR "/libvirt/libxl" # define LIBXL_AUTOSTART_DIR LIBXL_CONFIG_DIR "/autostart" # define LIBXL_STATE_DIR LOCALSTATEDIR "/run/libvirt/libxl" @@ -115,6 +118,9 @@ struct _libxlDriverPrivate { /* Immutable pointer, self-locking APIs */ virPortAllocatorPtr reservedVNCPorts;

[libvirt] [PATCH 0/2] Add support of SASL authentication for QEMU migration
by Sahid Orentino Ferdjaoui 30 Apr '14

30 Apr '14

This is a first contribution, I have tried to follow the most as possible rules marked in HACKING. I hope this commit will be conform with the specifications. make check OK make syntax-check OK make -C tests valgrind OK Currently with peer to peer migration provided by virDomainMigrateToURI, QEMU migration code uses virConnectOpen() which means that all authentication callbacks are disabled. Since no auth callback is present, SASL doesn't find any mechanisms and thus auth fails with the error: "authentication failed: Failed to start SASL negotiation: -4 (SASL(-4): no mechanism available: No worthy mechs found)" The PATCH 1/2 adds a new example to illustrate how to use peer to peer migration. This patch is not necessary to fix the problem and can be removed. It is provided to help reviewers by avoiding the necessary to create code that use this feature. Also as it demonstrates the performance of libvirt I have thought it could be interesting to keep it for new users. The PATCH 2/2 fixes the problem by configuring QEMU migration code to use virConnectOpenAuth instead of virConnectOpen. Indeed this function will call if necessary a callback responsible to fetching credentials.

[libvirt] [PATCH] virstoragetest: Don't run the test on 32 bit arches
by Michal Privoznik 30 Apr '14

30 Apr '14

Currently, there's an issue with virStrToLong_* APIs that they turn "-1" into UINT_MAX. While this is not acceptable, it works on 64 bit architectures and doesn't work on 32 bit ones. I know that much cleaner solution is required, but given that we are in the freeze we may as well just skip the test on 32 bits.

[libvirt] Entering freeze for libvirt-1.2.4
by Daniel Veillard 30 Apr '14

30 Apr '14

As planned on Friday, I tagged the tree earlier today for Release Candidate 1, the tarball and rpms are available from the usual place: ftp://libvirt.org/libvirt/ Seems to work fine in my limited testing, but distcheck failed with xsltproc being unable to access ../../ . I don't think anything changed there on my side so it smells like a new problem. Otherwise looks good to me so far, with a bit of luck we can push 1.2.4 end of Friday or sometime next week-end, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH 00/26] Rewrite firewall code to use formal API
by Daniel P. Berrange 29 Apr '14

29 Apr '14

Currently we have three places which interact with the firewall - util/virebtables - simple MAC filtering used by QEMU driver - util/viriptables - used by network driver - nwfilter - general purpose guest filtering All of these have been hacked to support firewalld by re-directing them via the 'firewall-cmd' command line tool. Unfortunately talking to firewalld via this CLI tool is incredibly inefficient. eg timing the network driver $ for i in `seq 1 10` ; do virsh net-start default; virsh net-destroy default ; done Direct iptables: 3 seconds Via firewall-cmd: 42 seconds Or timing the nwfilter driver via libvirt-tck/scripts/nwfilter/050-apply-verify-host.t Direct iptables: 28 seconds Via firewall-cmd: 479 seconds IOW it is more than x10 slower to use firewall-cmd. Testing revealed that this performance penalty is entirely due to the 'firewall-cmd' command line tool. If you talk directly to firewalld over DBus then the performance is near native. Unfortunately switching to use the DBus API is non-trivial since all the code we have for interacting with the firewall is just constructing virCommand instances directly (viriptables) or constructing gross shell scripts (nwfilter). Thus to enable use of the DBus API this series introduces the concept of a new object and APIs for interacting with the firewall "virFirewall". This API is designed to be a fairly generic basis for interacting with any firewall. It just has a concept of a level (ethernet, ipv4 or ipv6) and lists of rules, where each rule is just a string array of args. The idea is that the mechanism for interacting with the firewall can be generic and portable, even though the actual rules will be different on Linux vs FreeBSD vs other OS. The initial virFirewall implementation supports direct iptables/ebtables invocation or the DBus firewalld API. Use of firewall-cmd has been killed completely. Adapting code to use virFirewall has been a pretty horrific job, so is split up into as many patches as is practical. By far the worst/hardest patch is the one for nwfilter applyNewRules method (patch 23). Fortunately the libvirt-tck has a large set of XML data files and corresponding expected iptables/ebtables rules. This series passes the libvirt-tck 100% before and after, so I'm fairly confident that all the core functionality is working correctly. I also introduced new unit tests, that re-use the XML files from the libvirt-tck to validate the actual iptables/ebtables commands that libvirt tests. I've run this unit test under valgrind and under the OOM simulator to identify and fix any crashes / leaks that the refactoring introduced. With this series applied the performance is vastly improved for firewalld eg timing the network driver $ for i in `seq 1 10` ; do virsh net-start default; virsh net-destroy default ; done Direct iptables: 3 seconds Via firewall-cmd: 3 seconds Or timing the nwfilter driver via libvirt-tck/scripts/nwfilter/050-apply-verify-host.t Direct iptables: 29 seconds Via firewall-cmd: 37 seconds IOW firewalld is only marginly slower than direct iptables usage now.

[libvirt] [PATCH] libxl: support ACPI shutdown flag
by Jim Fehlig 29 Apr '14

29 Apr '14

Add support for VIR_DOMAIN_SHUTDOWN_ACPI_POWER_BTN flag in libxlDomainShutdownFlags(). Inspired by similar functionality in the Xen xl client. Signed-off-by: Jim Fehlig <jfehlig(a)suse.com> --- I considered invoking libxl_send_trigger() immediately when VIR_DOMAIN_SHUTDOWN_ACPI_POWER_BTN flag is specified, but in the end decided to only honor the flag if a "normal" shutdown request failed. This behavior is similar to xl and conforms to the virDomainShutdownFlags() docs "If @flags is set to zero, then the hypervisor will choose the method of shutdown it considers best. To have greater control pass one or more of the virDomainShutdownFlagValues. The order in which the hypervisor tries each shutdown method is undefined, and a hypervisor is not required to support all methods." I'm certainly receptive to only invoking libxl_send_trigger() when VIR_DOMAIN_SHUTDOWN_ACPI_POWER_BTN is specified if folks think that is a better approach. src/libxl/libxl_driver.c | 26 ++++++++++++++++++++++---- 1 file changed, 22 insertions(+), 4 deletions(-) diff --git a/src/libxl/libxl_driver.c b/src/libxl/libxl_driver.c index b3f8df6..2b30c08 100644 --- a/src/libxl/libxl_driver.c +++ b/src/libxl/libxl_driver.c @@ -868,7 +868,7 @@ libxlDomainShutdownFlags(virDomainPtr dom, unsigned int flags) int ret = -1; libxlDomainObjPrivatePtr priv; - virCheckFlags(0, -1); + virCheckFlags(VIR_DOMAIN_SHUTDOWN_ACPI_POWER_BTN, -1); if (!(vm = libxlDomObjFromDomain(dom))) goto cleanup; @@ -883,17 +883,35 @@ libxlDomainShutdownFlags(virDomainPtr dom, unsigned int flags) } priv = vm->privateData; - if (libxl_domain_shutdown(priv->ctx, vm->def->id) != 0) { + ret = libxl_domain_shutdown(priv->ctx, vm->def->id); + if (ret == ERROR_NOPARAVIRT) { + if (flags & VIR_DOMAIN_SHUTDOWN_ACPI_POWER_BTN) { + VIR_DEBUG("PV control interface not available, " + "sending ACPI power button event."); + ret = libxl_send_trigger(priv->ctx, vm->def->id, + LIBXL_TRIGGER_POWER, 0); + } else { + virReportError(VIR_ERR_OPERATION_INVALID, + "%s", _("PV control interface not available, " + "preventing external graceful shutdown.

[libvirt] [PATCH] qemu: properly quit migration with abort_on_error
by Martin Kletzander 29 Apr '14

29 Apr '14

When EIO comes to qemu while it's replying to qemuMigrationUpdateJobStatus(), qemu blocks, the migration of RAM can complete in the meantime, and when qemu unblocks, it sends us BLOCK_IO_ERROR plus migrations "status": "complete". Even though we act upon the BLOCK_IO_ERROR by setting the proper state of the domain, the call still waits for the proper reply on monitor for query_migrate and after it gets it, it checks that migration is completed and the migration is finished. This is what abort_on_error flag was meant for (we can migrate with these errors, but this flag must inhibit such behaviour). Changing the order of the steps guarantees the flag works properly.
