[libvirt] [PATCHv3 0/4] util: fix libvirtd startup failure due to netlink error
by Laine Stump 07 May '12

07 May '12

The initial patch in this series is the same as the single patch I provided before, but in addition there are 3 new patches that take care of the fallout from 1/4 by: 2/4) removing hard-coding of the src nl_pid when virNetLinkCommand is sending a message 3/4) adding a helper function to retrieve the local nl_pid from a libnl socket and 4/4) using that value when appropriate (I think). As before, I'm unable to fully test this myself, so I won't push unless/until I get verification it works.

[libvirt] Submission Deadline Extension
by VHPC 12 06 May '12

06 May '12

we apologize if you receive multiple copies of this CFP =================================================================== CALL FOR PAPERS 7th Workshop on Virtualization in High-Performance Cloud Computing VHPC '12 as part of Euro-Par 2012, Rhodes Island, Greece =================================================================== Date: August 28, 2012 Workshop URL: http://vhpc.org SUBMISSION DEADLINE: June 11, 2012 - Full paper submission (extended) SCOPE: Virtualization has become a common abstraction layer in modern data centers, enabling resource owners to manage complex infrastructure independently of their applications. Conjointly, virtualization is becoming a driving technology for a manifold of industry grade IT services. The cloud concept includes the notion of a separation between resource owners and users, adding services such as hosted application frameworks and queueing. Utilizing the same infrastructure, clouds carry significant potential for use in high-performance scientific computing. The ability of clouds to provide for requests and releases of vast computing resources dynamically and close to the marginal cost of providing the services is unprecedented in the history of scientific and commercial computing. Distributed computing concepts that leverage federated resource access are popular within the grid community, but have not seen previously desired deployed levels so far. Also, many of the scientific data centers have not adopted virtualization or cloud concepts yet. This workshop aims to bring together industrial providers with the scientific community in order to foster discussion, collaboration and mutual exchange of knowledge and experience. The workshop will be one day in length, composed of 20 min paper presentations, each followed by 10 min discussion sections. Presentations may be accompanied by interactive demonstrations. TOPICS Topics of interest include, but are not limited to: Higher-level cloud architectures, focusing on issues such as: - Languages for describing highly-distributed compute jobs - Workload characterization for VM-based environments - Optimized communication libraries/protocols in the cloud - Cross-layer optimization of numeric algorithms on VM infrastructure - System and process/bytecode VM convergence - Cloud frameworks and API sets - Checkpointing/migration of large compute jobs - Instrumentation interfaces and languages - VMM performance (auto-)tuning on various load types - Cloud reliability, fault-tolerance, and security - Software as a Service (SaaS) architectures - Research and education use cases - Virtualization in cloud, cluster and grid environments - Cross-layer VM optimizations - Cloud use cases including optimizations - VM-based cloud performance modelling - Performance and cost modelling Lower-level design challenges for Hypervisors, VM-aware I/O devices, hardware accelerators or filesystems in VM environments, especially: - Cloud, grid and distributed filesystems - Hardware for I/O virtualization (storage/network/accelerators) - Storage and network I/O subsystems in virtualized environments - Novel software approaches to I/O virtualization - Paravirtualized I/O subsystems for modified/unmodified guests - Virtualization-aware cluster interconnects - Direct device assignment - NUMA-aware subsystems in virtualized environments - Hardware Accelerators in virtualization (GPUs/FPGAs) - Hardware extensions for virtualization - VMMs/Hypervisors for embedded systems Data Center management methods, including: - QoS and and service levels - VM cloud and cluster distribution algorithms - VM load-balancing in Clouds - Hypervisor extensions and tools for cluster and grid computing - Fault tolerant VM environments - Virtual machine monitor platforms - Management, deployment and monitoring of VM-based environments - Cluster provisioning in the Cloud PAPER SUBMISSION Papers submitted to the workshop will be reviewed by at least two members of the program committee and external reviewers. Submissions should include abstract, key words, the e-mail address of the corresponding author, and must not exceed 10 pages, including tables and figures at a main font size no smaller than 11 point. Submission of a paper should be regarded as a commitment that, should the paper be accepted, at least one of the authors will register and attend the conference to present the work. Accepted papers will be published in the Springer LNCS series - the format must be according to the Springer LNCS Style. Initial submissions are in PDF; authors of accepted papers will be requested to provide source files. Format Guidelines: http://www.springer.de/comp/lncs/authors.html Style template: ftp://ftp.springer.de/pub/tex/latex/llncs/latex2e/llncs2e.zip Abstract Submission Link: http://edas.info/newPaper.php?c=11943 IMPORTANT DATES Rolling abstract submission June 11, 2012 - Full paper submission (extended) June 29, 2012 - Acceptance notification July 20, 2012 - Camera-ready version due August 28, 2012 - Workshop Date CHAIR Michael Alexander (chair), TU Wien, Austria Gianluigi Zanetti (co-chair), CRS4, Italy Anastassios Nanos (co-chair), NTUA, Greece PROGRAM COMMITTEE Paolo Anedda, CRS4, Italy Giovanni Busonera, CRS4, Italy Brad Calder, Microsoft, USA Roberto Canonico, University of Napoli Federico II, Italy Tommaso Cucinotta, Alcatel-Lucent Bell Labs, Ireland Werner Fischer, Thomas-Krenn AG, Germany William Gardner, University of Guelph, USA Marcus Hardt, Forschungszentrum Karlsruhe, Germany Sverre Jarp, CERN, Switzerland Shantenu Jha, Louisiana State University, USA Xuxian Jiang, NC State, USA Nectarios Koziris, National Technical University of Athens, Greece Simone Leo, CRS4, Italy Ignacio Llorente, Universidad Complutense de Madrid, Spain Naoya Maruyama, Tokyo Institute of Technology, Japan Jean-Marc Menaud, Ecole des Mines de Nantes, France Dimitrios Nikolopoulos, Foundation for Research&Technology Hellas, Greece Jose Renato Santos, HP Labs, USA Walter Schwaiger, TU Wien, Austria Yoshio Turner, HP Labs, USA Kurt Tutschku, University of Vienna, Austria Lizhe Wang, Indiana University, USA Chao-Tung Yang, Tunghai University, Taiwan DURATION: Workshop Duration is one day.

[libvirt] [PATCH] qemu: don't modify domain on failed blockiotune
by Eric Blake 04 May '12

04 May '12

If you have a qemu build that lacks the blockio tune monitor command, then this command: $ virsh blkdeviotune rhel6u2 hda --total_bytes_sec 1000 error: Unable to change block I/O throttle error: internal error Unexpected error fails as expected (well, the error message is lousy), but the next dumpxml shows that the domain was modified anyway. Worse, that means if you save the domain then restore it, the restore will likely fail due to throttling being unsupported, even though no throttling should even be active because the monitor command failed in the first place. * src/qemu/qemu_driver.c (qemuDomainSetBlockIoTune): Check for error before making modification permanent. --- src/qemu/qemu_driver.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index a36c348..2fde15b 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -12011,9 +12011,9 @@ qemuDomainSetBlockIoTune(virDomainPtr dom, qemuDomainObjEnterMonitorWithDriver(driver, vm); ret = qemuMonitorSetBlockIoThrottle(priv->mon, device, &info); qemuDomainObjExitMonitorWithDriver(driver, vm); - vm->def->disks[idx]->blkdeviotune = info; if (ret < 0) goto endjob; + vm->def->disks[idx]->blkdeviotune = info; } if (flags & VIR_DOMAIN_AFFECT_CONFIG) { -- 1.7.7.6

[libvirt] disable usb?
by Gerd Hoffmann 04 May '12

04 May '12

Hi, Is there some way to disable usb altogether? libvirt used to just pass in '-usb'. With the arrival of usb2 support that changed into '-device uhci,...'. Problem is that this breaks with several machine types such as isapc. '-usb' is silently ignored in case the machine type can't handle usb. '-device uhci,...' leads to an error message though and the guest doesn't start. /me tried "<controller type='usb' model='none'/>" which didn't work. Just removing the controller from the xml doesn't work too, it gets automagically readded. Suggestions? thanks, Gerd

[libvirt] [PATCH v3 0/3] usb devices with same vendorID, productID hotplug support
by Guannan Ren 04 May '12

04 May '12

https://bugzilla.redhat.com/show_bug.cgi?id=815755 The set of patch tries to fix the issue when multiple usb devices with same idVendor, idProduct are availible on host, the usb device with lowest bus:device will be attached to guest if usb xml file is given like this: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x15e1'/> <product id='0x2007'/> </source> </hostdev> The reason is that the usb hotplug function searchs usb device in system files to match vendor and product id, the file with lowest number is always found first. After fix, in this case, libvirt will report an error like: # virsh attach-device rhel6u1 /tmp/usb.xml error: Failed to attach device from /tmp/usb.xml error: operation failed: multiple USB devices for 15e1:2007, use <address> to specify one At the same time, the usb part of domain initilization is also updated in patch 2/3 These patches also fix the problem when using the following xml, the usb device could be hotplugged in two domains without raising errors <hostdev mode='subsystem' type='usb' managed='yes'> <source> <address bus='6' device='7'/> </source> </hostdev> # virsh attach-device rhel6u12nd /tmp/usb_by_bus.xml error: Failed to attach device from /tmp/usb_by_bus.xml error: Requested operation is not valid: USB device 006:007 is in use by domain rhel6u1

[libvirt] [PATCH 2/2] Modify interface qemuDefaultScsiControllerModel().
by Li Zhang 04 May '12

04 May '12

Now, the libvirt sets the default module as 'ibmvscsi' for pseries, and 'lsi' for other platforms.The controller model should be set according to controller type, not only just the platform, otherwise, it will have to set controller's model externally to select right model for specific controller type. This patch is to modify the qemuDefaultScsiControllerModel() interface to set right controller model according to the controller's type. For pseries guest, PCI scsi controller is also supported. So the default scsi controller model is set according to the contrller type. If it is PCI scsi controller, the default model is set as lsi, and if it is VSCSI controller, the default model is set as ibmvscsi.

[libvirt] [PATCH 1/1] Support libnl-3 as well as libnl-1
by Serge Hallyn 03 May '12

03 May '12

configure.ac: Check for libnl-3. If found, find libnl-route-3. If not found, do the original check to look for libnl-1. src/util/virnetlink.c: support libnl3 api. I could play games to make the patch smaller, but this would just hide what is actually needing to be done at the expense of clarity. src/Makefile.am and daemon/Makefile.am: Add LIBNL_ROUTE3_{LIBS,CFLAGS} Unfortunately libnl3 moves netlink/msg.h to /usr/include/libnl3/netlink/msg.h, which is the reason why the LIBNL_CFLAGS need to be added to a bunch of places where they weren't needed with libnl1. Those spots probaby don't actually need to also have LIBNL*LIBS added, but while I may be looking at it wrong, it seemed right to do so. I haven't gotten as far as to compile this into a package on ubuntu, but the source does build with libnl-3 as well as with libnl-1.

[libvirt] [PATCH - 2 alternatives] util: fix libvirtd startup failure due to netlink error
by Laine Stump 03 May '12

03 May '12

The two following patches fix the same problem (described in https://bugzilla.redhat.com/show_bug.cgi?id=816465) in two alternate ways - one by retrying the failing operation after a delay, the other by using knowledge of how libnl works internally to artificially "reserve" a particular address so libnl doesn't attempt to bind to it. You might think that libnl is the right place to fix this bug. Unfortunately, that isn't possible, because it would involve changing libnl's API - currently libnl decides what address to use for future binds of a netlink socket at the time nl_handle_alloc() is called, but doesn't actually attempt to bind it. Later, during nl_connect(), it calls bind() with the address it had earlier decided. It would be nice if we could just retry the bind with a different address when the first attempt failed, but libnl allows client applications to retrieve the bind address *before nl_connect() is called*, so an application may have already gotten the address prior to calling nl_connect(), and changing it would render the applications information incorrect. So the best we can do (for now at least) is work around the problem, and these are two possible workarounds.

[libvirt] [PATCH] Use XDG Base Directories instead of storing in home directory
by William Jon McCann 03 May '12

03 May '12

As defined in: http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html This offers a number of advantages: * Allows sharing a home directory between different machines, or sessions (eg. using NFS) * Cleanly separates cache, runtime (eg. sockets), or app data from user settings * Supports performing smart or selective migration of settings between different OS versions * Supports reseting settings without breaking things * Makes it possible to clear cache data to make room when the disk is filling up * Allows us to write a robust and efficient backup solution * Allows an admin flexibility to change where data and settings are stored * Dramatically reduces the complexity and incoherence of the system for administrators --- AUTHORS | 1 + daemon/libvirtd-config.c | 10 +-- daemon/libvirtd.c | 143 +++++++++++++++++++++++++++++++++------- daemon/libvirtd.pod.in | 2 +- docs/auth.html.in | 2 +- docs/uri.html.in | 2 +- src/libvirt.c | 4 +- src/libvirt_private.syms | 4 ++ src/network/bridge_driver.c | 8 ++- src/nwfilter/nwfilter_driver.c | 11 +--- src/qemu/qemu_driver.c | 32 +++++---- src/remote/remote_driver.c | 4 +- src/remote/remote_driver.h | 2 +- src/secret/secret_driver.c | 11 +--- src/storage/storage_driver.c | 13 +--- src/uml/uml_driver.c | 10 +-- src/util/util.c | 67 +++++++++++++++++++ src/util/util.h | 4 ++ src/util/virauth.c | 4 +- tools/virsh.c | 6 +- 20 files changed, 251 insertions(+), 89 deletions(-) diff --git a/AUTHORS b/AUTHORS index 06b830a..668eca1 100644 --- a/AUTHORS +++ b/AUTHORS @@ -234,6 +234,7 @@ Patches have also been contributed by: Jan Kiszka <jan.kiszka(a)siemens.com> Ryan Woodsmall <rwoodsmall(a)gmail.com> Wido den Hollander <wido(a)widodh.nl> + William Jon McCann <jmccann(a)redhat.com> [....send patches to get your name here....] diff --git a/daemon/libvirtd-config.c b/daemon/libvirtd-config.c index 471236c..8b95969 100644 --- a/daemon/libvirtd-config.c +++ b/daemon/libvirtd-config.c @@ -205,16 +205,16 @@ daemonConfigFilePath(bool privileged, char **configfile) if (!(*configfile = strdup(SYSCONFDIR "/libvirt/libvirtd.conf"))) goto no_memory;

[libvirt] [PATCH v2 0/3]usb devices with same vendorID, productID hotplug support
by Guannan Ren 03 May '12

03 May '12

https://bugzilla.redhat.com/show_bug.cgi?id=815755 The set of patch tries to fix the issue when multiple usb devices with same idVendor, idProduct are availible on host, the usb device with lowest bus:device will be attached to guest if usb xml file is given like this: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x15e1'/> <product id='0x2007'/> </source> </hostdev> The reason is that the usb hotplug function searchs usb device in system files to match vendor and product id, the file with lowest number is always found first. After fix, in this case, libvirt will report an error as follows: At the same time, the usb part of domain initilization is also update in patch 2/3 # virsh attach-device rhel6u1 /tmp/usb.xml error: Failed to attach device from /tmp/usb.xml error: XML error: multiple USB deivces 15e1:2007, use <address> to specify one. The patch also fix the problem when using the following xml, the usb device could be hotplugged in two domains without raising errors. <hostdev mode='subsystem' type='usb' managed='yes'> <source> <address bus='6' device='4'/> </source> </hostdev>

[libvirt] [PATCH] Use XDG Base Directories instead of storing in home
by William Jon McCann 03 May '12

03 May '12

Hi, New to the list so hopefully I'm following the correct protocol. Attached is a patch (mostly untested at the moment) to change the default storage location from .libvirt to the locations defined in the XDG Base Directory Specification (http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) This has a number of advantages for us: It allows sharing a home directory between different machines, or sessions (eg. using NFS) Cleanly separates cache, runtime (eg. sockets), or app data from user settings Supports performing smart or selective migration of settings between different OS versions Supports reseting settings without breaking things Makes it possible to clear cache data to make room when the disk is filling up Allows us to write a robust and efficient backup solution Allows an admin flexibility to change where data and settings are stored It dramatically reduces the complexity and incoherence of the system for administrators This is a pretty important set of features for both enterprise and individual use cases. I hope you will please consider the change. Thanks, Jon PS. This is also related to a goal for upstream GNOME https://live.gnome.org/GnomeGoals/XDGConfigFolders

[libvirt] [PATCH qemu v2 0/6] -no-user-config option, move CPU models to /usr/share
by Eduardo Habkost 02 May '12

02 May '12

Changes v1 -> v2: - Move qemu_read_default_config_files() prototype to qemu-config.h - Make defconfig and userconfig variable bool - Coding style change Patches 1 to 4 just move some code around, patch 5 just adds the new option without adding any new config file. Patch 6 finally creates a /usr/share/qemu /cpus-x86_64.conf file, with the CPU models we currently have on Qemu. Reference to previous discussion: - http://marc.info/?l=qemu-devel&m=133278877315665 Eduardo Habkost (6): move code to read default config files to a separate function (v2) eliminate arch_config_name variable move list of default config files to an array vl.c: change 'defconfig' variable to bool implement -no-user-config command-line option (v2) move CPU definitions to /usr/share/qemu/cpus-x86_64.conf (v2) Makefile | 12 +++- arch_init.c | 32 ++++++++- arch_init.h | 2 - qemu-config.h | 4 + qemu-options.hx | 16 ++++- sysconfigs/target/cpus-x86_64.conf | 128 ++++++++++++++++++++++++++++++++++ sysconfigs/target/target-x86_64.conf | 128 ---------------------------------- vl.c | 18 ++--- 8 files changed, 193 insertions(+), 147 deletions(-) create mode 100644 sysconfigs/target/cpus-x86_64.conf -- 1.7.3.2

[libvirt] [PATCH 1/2] virsh: make -h always give help
by Eric Blake 01 May '12

01 May '12

https://bugzilla.redhat.com/show_bug.cgi?id=817244 mentions that unlike most other tools, where --help or --version prevent all further parsing of all later options, virsh was strange in that --version stopped parsing but --help tried to plow on to the end.

[libvirt] [PATCH] util: fix crash when starting macvtap interfaces
by Laine Stump 01 May '12

01 May '12

This patch resolves https://bugzilla.redhat.com/show_bug.cgi?id=815270 The function virNetDevMacVLanVPortProfileRegisterCallback() takes an arg "virtPortProfile", and was checking it for non-NULL before using it. However, the prototype for virNetDevMacVLanPortProfileRegisterCallback had marked that arg with ATTRIBUTE_NONNULL(). Contrary to what one may think, ATTRIBUTE_NONNULL() does not provide any guarantee that an arg marked as such really is always non-null; the only effect to the code generated by gcc, is that gcc *assumes* it is non-NULL; this results in, for example, the check for a non-NULL value being optimized out. (Unfortunately, this code removal only occurs when optimization is enabled, and I am in the habit of doing local builds with optimization off to ease debugging, so the bug didn't show up in my earlier local testing). In general, virPortProfile might always be NULL, so it shouldn't be marked as ATTRIBUTE_NONNULL. One other function prototype made this same error, so this patch fixes it as well. --- src/util/virnetdevmacvlan.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/util/virnetdevmacvlan.h b/src/util/virnetdevmacvlan.h index 2299f1d..07d54e2 100644 --- a/src/util/virnetdevmacvlan.h +++ b/src/util/virnetdevmacvlan.h @@ -82,7 +82,7 @@ int virNetDevMacVLanRestartWithVPortProfile(const char *cr_ifname, virNetDevVPortProfilePtr virtPortProfile, enum virNetDevVPortProfileOp vmOp) ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) - ATTRIBUTE_NONNULL(4) ATTRIBUTE_NONNULL(5) ATTRIBUTE_RETURN_CHECK; + ATTRIBUTE_NONNULL(4) ATTRIBUTE_RETURN_CHECK; int virNetDevMacVLanVPortProfileRegisterCallback(const char *ifname, const unsigned char *macaddress , @@ -91,5 +91,5 @@ int virNetDevMacVLanVPortProfileRegisterCallback(const char *ifname, virNetDevVPortProfilePtr virtPortProfile, enum virNetDevVPortProfileOp vmOp) ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) -ATTRIBUTE_NONNULL(4) ATTRIBUTE_NONNULL(5) ATTRIBUTE_RETURN_CHECK; +ATTRIBUTE_NONNULL(4) ATTRIBUTE_RETURN_CHECK; #endif /* __UTIL_MACVTAP_H__ */ -- 1.7.10

[libvirt] [PATCH V13 0/5] Add DHCP snooping support to nwfilter
by Stefan Berger 01 May '12

01 May '12

This series of patches adds DHCP snooping support to libvirt's nwfilter subsystem. DHCP snooping detects DHCP leases obtained by a VM and automatically adjusts the network traffic filters to reflect the IP addresses with which a VM may send its traffic, thus for example preventing IP address spoofing. Once leases on IP addresses expire or if a VM gives up on a lease on an IP address, the filters are also adjusted. All leases are persisted and automatically applied upon a VM's restart. Leases are associated with the tuple of VM-UUID and interface MAC address. The following interface XML activates and uses the DHCP snooping: <interface type='bridge'> <source bridge='virbr0'/> <filterref filter='clean-traffic'> <parameter name='CTRL_IP_LEARNING' value='dhcp'/> </filterref> </interface> Once an IP address has been detected on an interface, 'virsh dumpxml <vm>' would show the IP address lease in the format <IP address>,<lease timeout in seconds>: <interface type='bridge'> <source bridge='virbr0'/> <filterref filter='clean-traffic'> <parameter name='CTRL_IP_LEARNING' value='dhcp'/> <parameter name='IP_LEASE' value='192.168.122.210,180'/> </filterref> </interface> Regards, David and Stefan

[libvirt] [PATCH 0/3] usb devices with same vendor, productID hotplug support
by Guannan Ren 01 May '12

01 May '12

https://bugzilla.redhat.com/show_bug.cgi?id=815755 The set of patch tries to fix the issue when multiple usb devices with same idVendor, idProduct are availible on host, the usb device with lowest bus:device will be attached to guest if usb xml file is given like this: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x15e1'/> <product id='0x2007'/> </source> </hostdev> The reason is that the usb hotplug function searchs usb device in system files to match vendor and product id, the file with lowest number is always found first. After fix, in this case, libvirt will report an error like: At the same time, the usb part of domain initilization is also update in patch 2/3 # virsh attach-device rhel6u1 /tmp/usb.xml error: Failed to attach device from /tmp/usb.xml error: XML error: multiple USB deivces 15e1:2007, use <address> to specify one.

[libvirt] [PATCH] Ensure libvirt_lxc process loads the live XML config
by Daniel P. Berrange 30 Apr '12

30 Apr '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> Currently the libvirt_lxc process uses VIR_DOMAIN_XML_INACTIVE when loading the XML for the container. This means it looses any dynamic data such as the, just allocated, SELinux label. Further there is an inconsistency in the libvirt LXC driver whereby it saves the live config XML and then later overwrites the file with the live status XML instead. Add a comment about this for future reference. * src/lxc/lxc_controller.c: Remove VIR_DOMAIN_XML_INACTIVE when loading XML * src/lxc/lxc_driver.c: Add comment about inconsistent config file formats Signed-off-by: Daniel P.

[libvirt] A couple of questions on snapshot-create/ snapshot-create-as
by Kashyap Chamarthy 30 Apr '12

30 Apr '12

Hi (Eric?), I got a couple of questions for 'snapshot-create' / 'snapshot-create-as' : 1/ can '--disk-only' option (when used with virsh snapshot-create-as) be run on an offline guest and generate an 'external snapshot' ? Or a running guest is needed? 2/ Can anyone point me to a bit more verbose info on these below options while creating snapshots? --quiesce quiesce guest's file systems --atomic require atomic operation --reuse-external reuse any existing external files Thanks. /kashyap

[libvirt] [PATCH] storage: Break out the loop if duplicate pool is found
by Osier Yang 30 Apr '12

30 Apr '12

It doesn't break out the "for" loop even if duplicate pool is found, and thus the "matchpool" could be overriden as NULL again if there is different pool afterwards.

[libvirt] [PATCH] storage: Allow multiple hosts for a storage pool
by Wido den Hollander 30 Apr '12

30 Apr '12

The current storage pools for NFS and iSCSI only require one host to connect to. Future storage pools like RBD and Sheepdog will require multiple hosts. This patch allows multiple source hosts and rewrites the current storage drivers.

[libvirt] [PATCH] qemu: Make sure qemu can access its directory in hugetlbfs
by Jiri Denemark 30 Apr '12

30 Apr '12

When libvirtd is started, we create "libvirt/qemu" directories under hugetlbfs mount point. Only the "qemu" subdirectory is chowned to qemu user and "libvirt" remains owned by root. If umask was too restrictive when libvirtd started, qemu user may lose access to "qemu" subdirectory.

[libvirt] libvirt stable releases
by Cole Robinson 29 Apr '12

29 Apr '12

Hi all, An idea we've kicked around for awhile in Red Hat/Fedora land is doing official libvirt stable releases, but nothing ever took shape. The idea was brought up again recently and I've offered to help get something going. I've pushed an upstream v0.9.11-maint branch with a bunch of patches cherry-picked to libvirt 0.9.11. Shortly I'll be cutting a 0.9.11.1 and pushing it to the website, like other releases. Why 0.9.11? Because that's what we will be shipping in Fedora 17 :) Typically our policy with fedora is to stick with one libvirt version for the length of a release. Cutting stable releases should save us from having to backport patches, and hopefully get us more bug fixes than backporting only what our users report. So I don't plan on doing a similar branch for 0.9.12 or 0.9.13, but will probably do a branch in 6 months time for whatever libvirt version we are shipping in Fedora 18. While my primary motiviation at the moment is making Fedora maintenance easier, I hope that other distros will use the stable releases as well, where we can all benefit from each others QA and attention. Any feedback appreciated! Thanks, Cole

[libvirt] Schedule for next release libvirt-0.9.12
by Daniel Veillard 28 Apr '12

28 Apr '12

Assuming we try to stay on a monthly schedule, then I would suggest to enter the freeze around next Friday (27th April) and shoot for a release around the 4th of May. I'm supposed to be in vacation most of next week, but I think I will still be able to make the release candidate 1 We have a number of patch set which need further review to be pushed fully, and there are a few things in http://libvirt.org/pending.html which aren't false positive that we really ought to check and push :-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH v2] qemu_agent: Report error class at least
by Michal Privoznik 28 Apr '12

28 Apr '12

Currently, qemu GA is not providing 'desc' field for errors like we are used to from qemu monitor. Therefore, we fall back to this general 'unknown error' string. However, GA is reporting 'class' which is not perfect, but much more helpful than generic error string. Thus we should fall back to class firstly and if even no class is presented, then we can fall back to that generic string.

[libvirt] [PATCHv2] blockjob: fix block-stream bandwidth race
by Eric Blake 27 Apr '12

27 Apr '12

With RHEL 6.2, virDomainBlockPull(dom, dev, bandwidth, 0) has a race with non-zero bandwidth: there is a window between the block_stream and block_job_set_speed monitor commands where an unlimited amount of data was let through, defeating the point of a throttle. This race was first identified in commit a9d3495e, and libvirt was able to reduce the size of the window for that race. In the meantime, the qemu developers decided to fix things properly; per this message: https://lists.gnu.org/archive/html/qemu-devel/2012-04/msg03793.html the fix will be in qemu 1.1, and changes block-job-set-speed to use a different parameter name, as well as adding a new optional parameter to block-stream, which eliminates the race altogether. Since our documentation already mentioned that we can refuse a non-zero bandwidth for some hypervisors, I think the best solution is to do just that for RHEL 6.2 qemu, so that the race is obvious to the user (anyone using stock RHEL 6.2 binaries won't have this patch, and anyone building their own libvirt with this patch for RHEL can also rebuild qemu to get the modern semantics, so it is no real loss in behavior). Meanwhile the code must be fixed to honor actual qemu 1.1 naming. Rename the parameter to 'modern', since the naming difference now covers more than just 'async' block-job-cancel. And while at it, fix an unchecked integer overflow. * src/qemu/qemu_monitor.h (enum BLOCK_JOB_CMD): Drop unused value, rename enum to match conventions. * src/qemu/qemu_monitor.c (qemuMonitorBlockJob): Reflect enum rename. * src/qemu_qemu_monitor_json.h (qemuMonitorJSONBlockJob): Likewise. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONBlockJob): Likewise, and support difference between RHEL 6.2 and qemu 1.1 block pull. * src/qemu/qemu_driver.c (qemuDomainBlockJobImpl): Reject bandwidth during pull with too-old qemu. * src/libvirt.c (virDomainBlockPull, virDomainBlockRebase): Document this. --- v2: fix integer overflow, improve variable naming src/libvirt.c | 8 ++++- src/qemu/qemu_driver.c | 8 +++-- src/qemu/qemu_monitor.c | 25 +++++++++++++----- src/qemu/qemu_monitor.h | 15 +++++----- src/qemu/qemu_monitor_json.c | 59 +++++++++++++++++++++++------------------ src/qemu/qemu_monitor_json.h | 6 ++-- 6 files changed, 72 insertions(+), 49 deletions(-) diff --git a/src/libvirt.c b/src/libvirt.c index b01ebba..cfd7711 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -18145,7 +18145,9 @@ error: * The maximum bandwidth (in Mbps) that will be used to do the copy can be * specified with the bandwidth parameter.

[libvirt] [ANNOUNCE] libvirt-glib 0.0.8 release
by Daniel P. Berrange 27 Apr '12

27 Apr '12

am pleased to announce that a new release of the libvirt-glib package, version 0.0.8 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: - Fix build of test suites with Debian's libtool - Add API for disk source startup policy - Add API for domain controller devices - Add APIs for USB controllers - Add APIs for USB / PCI device addressing schemes - Add APIs for USB redirection devices - Add ASync API for fetching domain info - Add APIs for domain timer configuration 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, for the first few releases, we are *NOT* guaranteeing that libvirt-glib libraries are API/ABI stable. ABI stability will only be guaranteed once the bulk of the APIs have been fleshed out and proved in non-trivial application usage. We anticipate this will be within the next 6 months in order to line up with Fedora 17. Follow up comments about libvirt-glib should be directed to the regular libvir-list redhat com development list. Thanks to all the people involved in contributing to this release. -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|

[libvirt] Memory leak due to virCopyError()
by Stefan Berger 27 Apr '12

27 Apr '12

If someone has the time ... I am seeing a memory leak in this code path. The leak seems to be triggerable by shutting down a VM: ==4717== 40 bytes in 1 blocks are definitely lost in loss record 547 of 1,014 ==4717== at 0x4A05E46: malloc (vg_replace_malloc.c:195) ==4717== by 0x38EC27FC01: strdup (strdup.c:43) ==4717== by 0x4EA55E0: virCopyError (virterror.c:255) ==4717== by 0x4EA58B1: virCopyLastError (virterror.c:356) ==4717== by 0x4CB4B6: qemuMonitorIO (qemu_monitor.c:646) ==4717== by 0x4E80C7F: virEventPollDispatchHandles (event_poll.c:490) ==4717== by 0x4E8150B: virEventPollRunOnce (event_poll.c:637) ==4717== by 0x4E7F5B7: virEventRunDefaultImpl (event.c:247) ==4717== by 0x4FA4F50: virNetServerRun (virnetserver.c:713) ==4717== by 0x4221AF: main (libvirtd.c:1133) My guess is the leak is related to the initialization of the error structure as for example here: int virConnCopyLastError(virConnectPtr conn, virErrorPtr to) { /* We can't guarantee caller has initialized it to zero */ memset(to, 0, sizeof(*to)); if (conn == NULL) return -1; virMutexLock(&conn->lock); if (conn->err.code == VIR_ERR_OK) virResetError(to); else After memset'ting 'to' to all zeros, the call to virResetError() seems pointless... Such memsets are also in other places potentially overwriting previously allocated pointers... Stefan

[libvirt] [libvirt-TCK][PATCH] use 'raw' format as the format of backing file of qcow2 image
by Guannan Ren 27 Apr '12

27 Apr '12

If we don't explicitly specify the format of backing file, it should use raw by default, if so, libvirt's security drivers should *not* grant access to the last.img file & the guest should not see the last.img data.

[libvirt] [PATCH 2/2] [TCK] nwfilter: Add test cases for ipset
by Stefan Berger 27 Apr '12

27 Apr '12

Add test cases for the ipset extension. Since ipset may not be available on all system, the first line of the XML file containing the test filter has been extended with a specially formatted XML comment containing a command line test for whether the test case can be run at all. The format of that line is:  If the tests in this line don't succeed, the test case is skipped. Also add a test case cleaning up the created ipset. Run this test after all other tests using alphabetical ordering. --- scripts/nwfilter/nwfilter2vmtest.sh | 36 +++++++-- scripts/nwfilter/nwfilterxml2fwallout/ipset-test.fwall | 39 ++++++++++ scripts/nwfilter/nwfilterxml2fwallout/zzz-ipset-cleanup.fwall | 1 scripts/nwfilter/nwfilterxml2xmlin/ipset-test.xml | 25 ++++++ scripts/nwfilter/nwfilterxml2xmlin/zzz-ipset-cleanup.xml | 5 + 5 files changed, 99 insertions(+), 7 deletions(-) Index: libvirt-tck/scripts/nwfilter/nwfilterxml2xmlin/ipset-test.xml =================================================================== --- /dev/null +++ libvirt-tck/scripts/nwfilter/nwfilterxml2xmlin/ipset-test.xml @@ -0,0 +1,25 @@ + +<filter name='tck-testcase' chain='root'> + <uuid>5c6d49af-b071-6127-b4ec-6f8ed4b55335</uuid> + <rule action='accept' direction='out'> + <all ipset='tck_test' ipsetflags='src,dst' /> + </rule> + <rule action='accept' direction='in'> + <all state='NONE' ipset='tck_test' ipsetflags='src,dst' comment='in+NONE'/> + </rule> + <rule action='accept' direction='out'> + <all state='NONE' ipset='tck_test' ipsetflags='src,dst' comment='out+NONE'/> + </rule> + <rule action='accept' direction='in'> + <all ipset='tck_test' ipsetflags='SRC,DST,SRC' /> + </rule> + <rule action='accept' direction='in'> + <all ipset='tck_test' ipsetflags='SRC,dSt,SRC' /> + </rule> + <rule action='accept' direction='in'> + <all ipset='$IPSETNAME' ipsetflags='src,dst' /> + </rule> + <rule action='accept' direction='inout'> + <all ipset='$IPSETNAME' ipsetflags='src,dst' comment='inout'/> + </rule> +</filter> Index: libvirt-tck/scripts/nwfilter/nwfilter2vmtest.sh =================================================================== --- libvirt-tck.orig/scripts/nwfilter/nwfilter2vmtest.sh +++ libvirt-tck/scripts/nwfilter/nwfilter2vmtest.sh @@ -107,6 +107,7 @@ checkExpectedOutput() { ifname="$3" flags="$4" skipregex="$5" + skiptest="$6" regex="s/${ORIG_IFNAME}/${ifname}/g" tmpdir=$(mktmpdir) @@ -147,6 +148,18 @@ checkExpectedOutput() { break fi + if [ -n "${skiptest}" ]; then + # treat all skips as passes + passctr=$(($passctr + 1)) + [ $(($flags & $FLAG_VERBOSE)) -ne 0 ] && \ + echo "SKIP ${xmlfile} : ${cmd}" + [ $(($flags & $FLAG_LIBVIRT_TEST)) -ne 0 ] && \ + test_result $(($passctr + $failctr)) "" 0 + [ $(($flags & $FLAG_TAP_TEST)) -ne 0 ] && \ + tap_pass $(($passctr + $failctr)) "SKIP: ${xmlfile} : ${skiptest}" + break + fi + diff -w ${tmpfile} ${tmpfile2} >/dev/null if [ $?

[libvirt] [PATCH v2 0/2] QEMU copyright update
by Andreas Färber 27 Apr '12

27 Apr '12

Hello, For 1.0 I had brought up the issue that the copyright statement reads 2008. Mentor Graphics have solved this for their Sourcery CodeBench fork by printing: Copyright (c) 2003-2008 Fabrice Bellard, 2008-2011 Mentor Graphics For the QEMU community it's less clear whom to assign the copyright to, thus my proposal is the appendix "and contributors". v2 applies this change to softmmus, linux-user and bsd-user (pointed out by PMM). darwin-user is intentionally left out as there is a pending PULL for its removal. Also included is a change to the bsd-user version banner. CC'ing libvirt since it has been sensitive to changes there in the past. Regards, Andreas Cc: Anthony Liguori <anthony(a)codemonkey.ws> Cc: Fabrice Bellard <fabrice(a)bellard.org> Cc: Peter Maydell <peter.maydell(a)linaro.org> Cc: Natalia Portillo <claunia(a)claunia.com> Cc: libvirt <libvir-list(a)redhat.com> Andreas Färber (2): Update copyright banners bsd-user: Output package version bsd-user/main.c | 3 ++- linux-user/main.c | 2 +- vl.c | 3 ++- 3 files changed, 5 insertions(+), 3 deletions(-) -- 1.7.7

[libvirt] How to disconnect a NIC
by Hendrik Schwartke 27 Apr '12

27 Apr '12

Hi, some time ago I wrote I patch to change the source bridge of a running domain. Now I'm wondering what's the best way to disconnect a NIC. My first thought was to set virDomainNetDef.data.bridge.brname to NULL. There are quite some places in the code that had to be modified to support this, but that should be doable. Another idea is to create a new interface type 'disconnected'. The purpose of this type would be specifying NICs (whose link state is either up or down) without any network connectivity. The type of this interface had to be changeable while the domain is running. Any thoughts would greatly appreciated. Hendrik Schwartke

Can we just update the tar format in configure or does that come with caveats? Thanks, Cole

[libvirt] udevadm settle can take too long
by Jim Paris 27 Apr '12

27 Apr '12

Hi, http://bugs.debian.org/663931 is a bug I'm hitting, where virt-manager times out on the initial connection to libvirt. The basic problem is that, while checking storage volumes, virt-manager causes libvirt to call "udevadm settle". There's an interaction where libvirt's earlier use of network namespaces (to probe LXC features) had caused some uevents to be sent that get filtered out before they reach udev. This confuses "udevadm settle" a bit, and so it sits there waiting for a 2-3 minute built-in timeout before returning. Eventually libvirtd prints: 2012-04-22 18:22:18.678+0000: 30503: warning : virKeepAliveTimer:182 : No response from client 0x7feec4003630 after 5 keepalive messages in 30 seconds and virt-manager prints: 2012-04-22 18:22:18.931+0000: 30647: warning : virKeepAliveSend:128 : Failed to send keepalive response to client 0x25004e0 and the connection gets dropped. One workaround could be to specify a shorter timeout when doing the settle. The patch appended below allows virt-manager to work, although the connection still has to wait for the 10 second timeout before it succeeds. I don't know what a better solution would be, though. It seems the udevadm behavior might not be considered a bug from the udev/kernel point of view: https://lkml.org/lkml/2012/4/22/60 I'm using Linux 3.2.14 with libvirt 0.9.11. You can trigger the udevadm issue using a program I posted at the Debian bug report link above. -jim >From 17e5b9ebab76acb0d711e8bc308023372fbc4180 Mon Sep 17 00:00:00 2001 From: Jim Paris <jim(a)jtan.com> Date: Sun, 22 Apr 2012 14:35:47 -0400 Subject: [PATCH] shorten udevadmin settle timeout Otherwise, udevadmin settle can take so long that connections from e.g. virt-manager will get closed. --- src/util/util.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/util/util.c b/src/util/util.c index 6e041d6..dfe458e 100644 --- a/src/util/util.c +++ b/src/util/util.c @@ -2593,9 +2593,9 @@ virFileFindMountPoint(const char *type ATTRIBUTE_UNUSED) void virFileWaitForDevices(void) { # ifdef UDEVADM - const char *const settleprog[] = { UDEVADM, "settle", NULL }; + const char *const settleprog[] = { UDEVADM, "settle", "--timeout", "10", NULL }; # else - const char *const settleprog[] = { UDEVSETTLE, NULL }; + const char *const settleprog[] = { UDEVSETTLE, "--timeout", "10", NULL }; # endif int exitstatus; -- 1.7.7

[libvirt] [PATCH] qemu: improve errors related to offline domains
by Eric Blake 26 Apr '12

26 Apr '12

https://bugzilla.redhat.com/show_bug.cgi?id=816662 pointed out that attempting 'virsh blockpull' on an offline domain gave a misleading error message about qemu lacking support for the operation, even when qemu was specifically updated to support it. The real problem is that we have several capabilities that are only determined when starting a domain, and therefore are still clear when first working with an inactive domain (namely, any capability set by qemuMonitorJSONCheckCommands). While this patch was able to hoist an existing check in one of the three culprits, it had to add redundant checks in the other two places (because you always have to check for an active domain after obtaining a VM job lock, but the capability bits were being checked prior to obtaining the job lock). Someday it would be nice to patch libvirt to cache the set of capabilities per qemu binary (as determined by inode and timestamp), rather than re-probing the binary every time a domain is started, and to teach the cache how to query the monitor during the one time the probe is made rather than having to wait until a guest is started; then, a capability probe would succeed even for offline guests because it just refers to the cache, and the single check for an active domain after grabbing the job lock would be sufficient. But since that will involve a lot more coding, I'm happy to go with this simpler solution for an immediate solution. * src/qemu/qemu_driver.c (qemuDomainPMSuspendForDuration) (qemuDomainSnapshotCreateXML, qemuDomainBlockJobImpl): Check for offline state before checking an online-only cap. --- src/qemu/qemu_driver.c | 24 ++++++++++++++++++------ 1 files changed, 18 insertions(+), 6 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index d3aa34d..3a1c1c4 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -10389,6 +10389,12 @@ qemuDomainSnapshotCreateXML(virDomainPtr domain, goto cleanup; if (flags & VIR_DOMAIN_SNAPSHOT_CREATE_DISK_ONLY) { + if (!virDomainObjIsActive(vm)) { + qemuReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("disk snapshots of inactive domains not " + "implemented yet")); + goto cleanup; + } if (virDomainSnapshotAlignDisks(def, VIR_DOMAIN_DISK_SNAPSHOT_EXTERNAL, false) < 0) @@ -10443,12 +10449,6 @@ qemuDomainSnapshotCreateXML(virDomainPtr domain, * makes sense, such as checking that qemu-img recognizes the * snapshot name in at least one of the domain's disks? */ } else if (flags & VIR_DOMAIN_SNAPSHOT_CREATE_DISK_ONLY) { - if (!virDomainObjIsActive(vm)) { - qemuReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", - _("disk snapshots of inactive domains not " - "implemented yet")); - goto cleanup; - } if (qemuDomainSnapshotCreateDiskActive(domain->conn, driver, &vm, snap, flags) < 0) goto cleanup; @@ -11642,6 +11642,12 @@ qemuDomainBlockJobImpl(virDomainPtr dom, const char *path, const char *base, _("no domain with matching uuid '%s'"), uuidstr); goto cleanup; } + if (!virDomainObjIsActive(vm)) { + qemuReportError(VIR_ERR_OPERATION_INVALID, "%s", + _("domain is not running")); + goto endjob; + } + priv = vm->privateData; if (qemuCapsGet(priv->qemuCaps, QEMU_CAPS_BLOCKJOB_ASYNC)) { async = true; @@ -12637,6 +12643,12 @@ qemuDomainPMSuspendForDuration(virDomainPtr dom, priv = vm->privateData; + if (!virDomainObjIsActive(vm)) { + qemuReportError(VIR_ERR_OPERATION_INVALID, + "%s", _("domain is not running")); + goto endjob; + } + if (!qemuCapsGet(priv->qemuCaps, QEMU_CAPS_WAKEUP) && (target == VIR_NODE_SUSPEND_TARGET_MEM || target == VIR_NODE_SUSPEND_TARGET_HYBRID)) { -- 1.7.7.6

[libvirt] [PATCH] blockjob: fix block-stream bandwidth race
by Eric Blake 26 Apr '12

26 Apr '12

With RHEL 6.2, virDomainBlockPull(dom, dev, bandwidth, 0) has a race with non-zero bandwidth: there is a window between the block_stream and block_job_set_speed monitor commands where an unlimited amount of data was let through, defeating the point of a throttle. This race was first identified in commit a9d3495e, and libvirt was able to reduce the size of the window for that race. In the meantime, the qemu developers decided to fix things properly; per this message: https://lists.gnu.org/archive/html/qemu-devel/2012-04/msg03793.html the fix will be in qemu 1.1, and changes block-job-set-speed to use a different parameter name, as well as adding a new optional parameter to block-stream, which eliminates the race altogether. Since our documentation already mentioned that we can refuse a non-zero bandwidth for some hypervisors, I think the best solution is to do just that for RHEL 6.2 qemu, so that the race is obvious to the user. Meanwhile the code must be fixed to honor actual qemu 1.1 naming. * src/qemu/qemu_monitor.h (enum BLOCK_JOB_CMD): Drop unused value. * src/qemu/qemu_driver.c (qemuDomainBlockJobImpl): Reject bandwidth during pull with too-old qemu. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONBlockJob): Support difference between RHEL 6.2 and qemu 1.1 block pull. * src/libvirt.c (virDomainBlockPull, virDomainBlockRebase): Document this. --- src/libvirt.c | 6 +++- src/qemu/qemu_driver.c | 8 ++++-- src/qemu/qemu_monitor.h | 3 +- src/qemu/qemu_monitor_json.c | 53 +++++++++++++++++++++++------------------ 4 files changed, 40 insertions(+), 30 deletions(-) diff --git a/src/libvirt.c b/src/libvirt.c index af42d3b..67f324a 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -18145,7 +18145,8 @@ error: * The maximum bandwidth (in Mbps) that will be used to do the copy can be * specified with the bandwidth parameter.

[libvirt] SR-IOV VLANs
by Dax Kelson 26 Apr '12

26 Apr '12

How should libvirt deal with different SR-IOV VLAN scenarios? Hardware with full SR-IOV and ACS support is increasingly available and in production. I just took delivery of such a server this week. It would be nice if the software can fully take advantage of the hardware. == Scenario A - Transparent VLAN == In the first scenario a /single/ VLAN can be tied to a a VF and the tagging and stripping of the VLAN tag happens outside of the view of the VM. Since the VLAN management happens outside the VM there isn't any security concerns from a malicious VM. Today this can configured with the ip command: ip link set <pf> vf <vfN> vlan <vlanID> But, unless I'm reading it wrong, libvirtd will blow away any pre-configured transparent VLAN in qemuDomainHostdevNetConfigReplace == Scenario B - VM VLAN tagging == In the second scenario, tagged frames are delivered to the VM and the VM uses them like normal. There are security considerations here. You don't want a malicious VM to access arbitrary VLANs. There should be a way to have a whitelist of allowed VLAN tags that can be enforced per VF at lower layer than the VM. Unfortunately it doesn't seem like hardware today supports this granularity. The Intel x540 datasheet indicates that a VLAN filter can be programmed with up to 8 VLANs, but I'm not sure if that is per VF or a global limit. With Emulex hardware, running: "ip link set <pf> vf <vfN> vlan 4095" allows the VM with the given VF to configure any VLAN. Likewise, the Intel ixgbe driver has ixgbe_set_vlan_anti_spoofing (and ixgbe_set_mac_anti_spoofing) on a per VF basis. It isn't clear to me if IFLA_VF_SPOOFCHK toggles both or just the mac anti spoofing.

[libvirt] [PATCH] build: fix bootstrap on RHEL
by Eric Blake 25 Apr '12

25 Apr '12

Commit 8fe455fd364cd7462e02170084c45a58ee302cc3 tried to work around a regression introduced in upstream gnulib that requires gettext 0.18 or newer on all projects using bootstrap, by making libvirt require gettext 0.18. But this fails on RHEL 6.2, which still ships gettext 0.17. Revert that change, and instead, import the latest round of gnulib updates that fix that problem properly. If you have already built in the window where libvirt required 0.18, be aware that incremental updates may run into problems: this is because 'autopoint --force' will not downgrade m4/po.m4 back to an older version, but it must be downgraded back to 0.17 levels to work with this patch. You may either manually remove that file then rerun bootstrap, or it may prove easier to just clean up all non-git files to start from a clean slate. * bootstrap.conf: Revert minimum gettext back to 0.17. * configure.ac: Likewise. * .gnulib: Update to latest, for bootstrap fixes. * bootstrap: Resync from gnulib. --- Pushing under the build-breaker rule (and this took me a lot longer than I wanted, but I'm happy with the solution). * .gnulib f15a17d...bb2f564 (6): > bootstrap: only force latest Makefile.in.in for gettext module > doc: Mention reason for replacement on glibc/Linux systems. > pwrite: Don't replace on all platforms. > rint* tests: Avoid gcc warnings. > users.txt: Update. > Large File Support for native Windows platforms. .gnulib | 2 +- bootstrap | 12 ++++++++++-- bootstrap.conf | 2 +- configure.ac | 2 +- 4 files changed, 13 insertions(+), 5 deletions(-) diff --git a/.gnulib b/.gnulib index f15a17d..bb2f564 160000 --- a/.gnulib +++ b/.gnulib @@ -1 +1 @@ -Subproject commit f15a17dc1f5d2b1fc8a423795c54b211552c0483 +Subproject commit bb2f5640d5379c5b4eec2d62341413bbab1aa308 diff --git a/bootstrap b/bootstrap index 5aa73cc..6b45868 100755 --- a/bootstrap +++ b/bootstrap @@ -1,6 +1,6 @@ #! /bin/sh # Print a version string. -scriptversion=2012-04-19.22; # UTC +scriptversion=2012-04-25.17; # UTC # Bootstrap this package from checked-out sources. @@ -873,7 +873,15 @@ if test $with_gettext = yes; then } ' po/Makevars.template >po/Makevars || exit 1 - cat $GNULIB_SRCDIR/build-aux/po/Makefile.in.in > po/Makefile.in.in || exit 1 + # If the 'gettext' module is in use, grab the latest Makefile.in.in. + # If only the 'gettext-h' module is in use, assume autopoint already + # put the correct version of this file into place. + case $gnulib_modules in + *gettext-h*) ;; + *gettext*) + cp $GNULIB_SRCDIR/build-aux/po/Makefile.in.in po/Makefile.in.in || exit 1 + ;; + esac if test -d runtime-po; then # Similarly for runtime-po/Makevars, but not quite the same. diff --git a/bootstrap.conf b/bootstrap.conf index 56911e0..c6620e5 100644 --- a/bootstrap.conf +++ b/bootstrap.conf @@ -195,7 +195,7 @@ buildreq="\ autoconf 2.59 automake 1.9.6 autopoint - -gettext 0.18 +gettext 0.17 git 1.5.5 gzip - libtool - diff --git a/configure.ac b/configure.ac index 5936d31..89fe818 100644 --- a/configure.ac +++ b/configure.ac @@ -2300,7 +2300,7 @@ dnl compute the difference between save_CPPFLAGS and CPPFLAGS and append it dnl to INCLUDES in order to preserve changes made by gettext but in a place dnl that does not break the build save_CPPFLAGS="$CPPFLAGS" -AM_GNU_GETTEXT_VERSION([0.18]) +AM_GNU_GETTEXT_VERSION([0.17]) AM_GNU_GETTEXT([external]) GETTEXT_CPPFLAGS= if test "x$save_CPPFLAGS" != "x$CPPFLAGS"; then -- 1.7.7.6

[libvirt] More SR-IOV VF support needed (IFLA_VF_VLAN/IFLA_VF_SPOOFCHK)
by Dax Kelson 25 Apr '12

25 Apr '12

Hi guys, I have some brand new hardware with a Intel X540-AT2 10Gbe NIC. I see that 0.9.11 added <interface type='hostdev'> with the ability define a MAC address to address the randomly generated MAC address issue. Thank you! I believe that additional functionality is needed in two areas, namely support for transparent VLAN tagging and the ability to disable MAC spoof checking within the NIC's embedded switch. With transparent VLAN tagging (IFLA_VF_VLAN), the PF transparently tags all traffic from the VF with a configured VLAN ID and strips the VLAN tag from traffic going to the VM. The VM is not aware of the VLAN tag. Disabling of the MAC spoof check (IFLA_VF_SPOOFCHK) allows the VM to be able to do NIC bonding of two VFs. These two features correspond to the following commands: ip link set em<X> vf <n> vlan <VLAN> ip link set em<X> vf <n> spoofchk [on|off] (note, requires iproute2 v3.3.0) As far as XML format, how about something like: <devices> <interface type='hostdev'> <source> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </source> <mac address='52:54:00:6d:90:02'> <vlan id='241'> <disablespoofchk/> </interface> </devices> Comments?

[libvirt] [PATCH] virNetDevMacVLanVPortProfileRegisterCallback: Fix segfault

[libvirt] [PATCH 0/2] Filesystem limits for containers
by Guido Günther 24 Apr '12

24 Apr '12

Hi, the following two patches are a first stab at filesystem limits for containers. They're not ment for detailed review just to start the discussion. With these two patches space and inode limits in openvz containers are printed in the domain config as: <filesystem type='template' accessmode='passthrough'> <source name='debian'/> <target dir='/'/> <hardlimit>1153024</hardlimit> <softlimit>1048576</softlimit> <inodes_hardlimit>220000</inodes_hardlimit> <inodes_softlimit>200000</inodes_softlimit> </filesystem> Does this look o.k.? If so I'd cook up the schema updates and more parsing code. Other container solutions like lxc might have similar needs. Cheers, -- Guido Guido Günther (2): domain_conf: add filesystem limits to virDomainFSDef openvz; support file system quota reporting src/conf/domain_conf.c | 15 ++++++ src/conf/domain_conf.h | 4 ++ src/openvz/openvz_conf.c | 114 +++++++++++++++++++++++++++++----------------- 3 files changed, 92 insertions(+), 41 deletions(-) -- 1.7.10
