[libvirt] [PATCH] Fix bug #611823 prohibit pools with duplicate storage
by Lei Li 02 Aug '11

02 Aug '11

To make sure the unique storage pool defined and created from different directory to avoid inconsistent version of volume pool created, I add two API be called by storage driver to check for the probable duplicate pools and refused the duplicate pool. virStoragePoolObjFindByPath() provide a method to find pool object by target path in pool list. virStoragePoolTargetDuplicate() implement the function to check if there is duplicate pool. Add judgement for storagePoolCreate&storagePoolDefine by calling virStoragePoolTargetDuplicate() to avoid both transient storage pool and persistent storage pool be created repeatedly in storage driver.

[libvirt] [PATCHv4 0/2] vnc/spice listen address as a network name
by Laine Stump 02 Aug '11

02 Aug '11

This is the latest reincarnation of this patch series: https://www.redhat.com/archives/libvir-list/2011-July/msg01717.html In the previous version, I had created a new subelement of <graphics>, called <listen>, and placed all listen address and port attributes there. After discussion on the list and in IRC with Dan Berrange and Eric Blake, I became convinced that was overdoing things, and that really only the address or network name should be in the <listen> element, but that port/tlsPort/autoport should stay put. This version removes all changes to port-related attributes, paring it down to just the listen address (and the new listen network) attribute. This greatly simplifies the patch, so new review of it should be easier. Based on Eric's review, the nwe version tries to be more concise about what is accepted, what is ignored, and what is rejected in the XML, both by the parser and by the RNG. (since there is less to deal with, this is also easier.) Having a single port value but multiple addresses does create some potential future restrictions, which we can deal with an eliminate later if they become problematic. In particular, each graphics device will have only a single port, but could have multiple listen addresses; in this case, all the listen addresses would have to listen on the same port. (This isn't a problem right now, because all of our drivers can only listen on a single address anyway). (Note to Eric: I did consider putting the switch to helper functions into its own patch, but after removing all the ports from <listen>, the number of helper functions (and thus the number of changes created by switching to using them, has been reduced considerably, so the gain wouldn't be as much. (also, it's very late, and I'd like to get some sleep tonight :-)

[libvirt] [PATCH RFC] virsh: Add option to undefine storage with domains
by Peter Krempa 01 Aug '11

01 Aug '11

Adds an option to virsh undefine command to undefine managed storage volumes along with (inactive) domains. Storage volumes are enumerated and the user may interactivly choose volumes to delete. Unmanaged volumes are listed and the user shall delete them manualy. --- I marked this as a RFC because I am concerned about my "naming scheme" of the added parameters. I couldn't decide which of the following "volumes/storage/disks/..." to use. I'd appreciate your comments on this. This is my second approach to this problem after I got some really good critique from Eric, Daniel and Dave. The user has the choice to activate an interactive mode, that allows to select on a per-device basis which volumes/disks to remove along with the domain. To avoid possible problems, I only allowed to remove storage for inactive domains and unmanaged images (which sidetracked me a lot on my previous attempt) are left to a action of the user. (the user is notified about any unmanaged image for the domain). My next concern is about interactive of the user. I tried to implement a boolean query function, but I'd like to know if I took the right path, as I couldn't find any example in virsh from which I could learn.

[libvirt] [PATCH] support qemuMonitorSend() to be called at the same time
by Wen Congyang 01 Aug '11

01 Aug '11

Current, we support run sync job and async job at the same time. It means that the monitor commands for two jobs can be run in any order. In the function qemuDomainObjEnterMonitorInternal(): if (priv->job.active == QEMU_JOB_NONE && priv->job.asyncJob) { if (qemuDomainObjBeginNestedJob(driver, obj) < 0) We check whether the caller is an async job by priv->job.active and priv->job.asynJob. But when an async job is running, priv->job.active is QEMU_JOB_NONE if no sync job is running, or priv->job.active is not QEMU_JOB_NONE if a sync job is running. So we cannot check whether the caller is an async job in the function qemuDomainObjEnterMonitorInternal(). Unfortunately, if sync job and async job are running at the same time, we may try to send monitor command at the same time in two threads. It's very dangerous, and it will cause libvirtd crashed. We should enhance the function qemuMonitorSend() to support it to be called at the same time. If the last monitor command does not finish, the other monitor commands should wait it to finish. --- src/qemu/qemu_monitor.c | 22 +++++++++++++++++++++- 1 files changed, 21 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index db6107c..a10f53f 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -46,6 +46,8 @@ struct _qemuMonitor { virMutex lock; /* also used to protect fd */ virCond notify; + virCond send_notify; + int refs; int fd; @@ -675,7 +677,8 @@ qemuMonitorOpen(virDomainObjPtr vm, VIR_FREE(mon); return NULL; } - if (virCondInit(&mon->notify) < 0) { + if ((virCondInit(&mon->notify) < 0) || + (virCondInit(&mon->send_notify) < 0)) { qemuReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("cannot initialize monitor condition")); virMutexDestroy(&mon->lock); @@ -795,6 +798,22 @@ int qemuMonitorSend(qemuMonitorPtr mon, return -1; } + while (mon->msg) { + if (virCondWait(&mon->send_notify, &mon->lock) < 0) { + qemuReportError(VIR_ERR_INTERNAL_ERROR, "%s", + _("Unable to wait on monitor condition")); + goto cleanup; + } + } + + /* Check whether qemu quited unexpectedly again */ + if (mon->lastError.code != VIR_ERR_OK) { + VIR_DEBUG("Attempt to send command while error is set %s", + NULLSTR(mon->lastError.message)); + virSetError(&mon->lastError); + return -1; + } + mon->msg = msg; qemuMonitorUpdateWatch(mon); @@ -818,6 +837,7 @@ int qemuMonitorSend(qemuMonitorPtr mon, cleanup: mon->msg = NULL; qemuMonitorUpdateWatch(mon); + virCondBroadcast(&mon->send_notify); return ret; } -- 1.7.1

Alex, Regarding vdsm changing a device owner, Last time I asked in #virt for using usb device in vdsm hook in /dev/bus/usb/<addr> I was told that vdsm should change the owner to qemu:kvm. So for the sr-iov device /sys/bus/pci/devices/<addr>/resource*, rom, and reset libvirt should change the owner and not vdsm? Shahar Havivi.

[libvirt] [PATCH] network: don't forward DNS requests from isolated networks
by Laine Stump 29 Jul '11

29 Jul '11

This is in response to: https://bugzilla.redhat.com/show_bug.cgi?id=723862 which points out that a guest on an "isolated" network could potentially exploit the DNS forwarding provided by dnsmasq to create a communication channel to the outside. This patch eliminates that possibility by adding the "--no-resolv" argument to the dnsmasq commandline, which tells dnsmasq to not forward on any requests that it can't resolv itself (by looking at its own static hosts files and runtime lsit of dhcp clients), but to instead return a failure for those requests. This shouldn't cause any undesirable change from current behavior, even in the case where a guest is currently configured with multiple interfaces, one of them being connected to an isolated network, and another to a network that does have connectivity to the outside. If the isolated network's DNS server is queried for a name it doesn't know, it will return "Refused" rather than "Unknown", which indicates to the guest that it should query other servers, so it then queries the connected DNS server, and gets the desired response. --- src/network/bridge_driver.c | 11 ++++++++--- tests/networkxml2argvdata/isolated-network.argv | 3 ++- 2 files changed, 10 insertions(+), 4 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index b8c6c97..0a60bb8 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -531,10 +531,15 @@ networkBuildDnsmasqArgv(virNetworkObjPtr network, /* If this is an isolated network, set the default route option * (3) to be empty to avoid setting a default route that's - * guaranteed to not work. + * guaranteed to not work, and set --no-resolv so that no dns + * requests are forwarded on to the dns server listed in the + * host's /etc/resolv.conf (since this could be used as a channel + * to build a connection to the outside). */ - if (network->def->forwardType == VIR_NETWORK_FORWARD_NONE) - virCommandAddArg(cmd, "--dhcp-option=3"); + if (network->def->forwardType == VIR_NETWORK_FORWARD_NONE) { + virCommandAddArgList(cmd, "--dhcp-option=3", + "--no-resolv", NULL); + } if (network->def->dns != NULL) { virNetworkDNSDefPtr dns = network->def->dns; diff --git a/tests/networkxml2argvdata/isolated-network.argv b/tests/networkxml2argvdata/isolated-network.argv index f801396..7ea2e94 100644 --- a/tests/networkxml2argvdata/isolated-network.argv +++ b/tests/networkxml2argvdata/isolated-network.argv @@ -1,5 +1,6 @@ /usr/sbin/dnsmasq --strict-order --bind-interfaces --conf-file= \ ---except-interface lo --dhcp-option=3 --listen-address 192.168.152.1 \ +--except-interface lo --dhcp-option=3 --no-resolv \ +--listen-address 192.168.152.1 \ --dhcp-range 192.168.152.2,192.168.152.254 \ --dhcp-leasefile=/var/lib/libvirt/dnsmasq/private.leases --dhcp-lease-max=253 \ --dhcp-no-override\ -- 1.7.3.4

[libvirt] [PATCHv3 1/3] save: support qemu modifying xml on domain save/restore
by Eric Blake 29 Jul '11

29 Jul '11

With this, it is possible to update the path to a disk backing image on either the save or restore action, without having to binary edit the XML embedded in the state file. This also modifies virDomainSave to output a smaller xml (only the inactive xml, which is all the more virDomainRestore parses), while still guaranteeing padding for most typical abi-compatible xml replacements, necessary so that the next patch for virDomainSaveImageDefineXML will not cause unnecessary modifications to the save image file. * src/qemu/qemu_driver.c (qemuDomainSaveInternal): Add parameter, only use inactive state, and guarantee padding. (qemuDomainSaveImageOpen): Add parameter. (qemuDomainSaveFlags, qemuDomainManagedSave) (qemuDomainRestoreFlags, qemuDomainObjRestore): Update callers. --- v3: change virDomainSave to always output minimal information, but with fixed padding added, so that save file modification will always be more likely to succeed, and not generate quite as many xml differences on round trips. src/qemu/qemu_driver.c | 109 +++++++++++++++++++++++++++++------------------ 1 files changed, 67 insertions(+), 42 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 1401967..2b1df6c 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -2193,7 +2193,7 @@ qemuCompressProgramName(int compress) static int qemuDomainSaveInternal(struct qemud_driver *driver, virDomainPtr dom, virDomainObjPtr vm, const char *path, - int compressed, bool bypass_cache) + int compressed, bool bypass_cache, const char *xmlin) { char *xml = NULL; struct qemud_save_header header; @@ -2204,7 +2204,9 @@ qemuDomainSaveInternal(struct qemud_driver *driver, virDomainPtr dom, qemuDomainObjPrivatePtr priv; struct stat sb; bool is_reg = false; + size_t len; unsigned long long offset; + unsigned long long pad; int fd = -1; uid_t uid = getuid(); gid_t gid = getgid(); @@ -2239,15 +2241,54 @@ qemuDomainSaveInternal(struct qemud_driver *driver, virDomainPtr dom, } } - /* Get XML for the domain */ - xml = virDomainDefFormat(vm->def, VIR_DOMAIN_XML_SECURE); + /* Get XML for the domain.

As for images, use % virsh; and 'vol-create-as', or % qemu-img; command. % virsh -c qemu:///system ; and ' virsh # help vol-create-as ;' for details about this command. There is also % qemu-img;, however do not do things behind libvirt's back or it will backfire on you. I highly recommend to use either some cli tool/scripts eg. for VM definition or virt-manager or some other GUI tool.

[libvirt] [PATCH 0/4] xen callback cleanups
by Eric Blake 28 Jul '11

28 Jul '11

Noticed because of the recent xen break in commit 1edf5cc5 (fixed in 934fdcb3), which broke because it touched too many files, rather than focusing on just xen_driver.c. Renaming all xen callback structs makes it easier to grep for use of the callback structs, which in turn makes it easier to see what still remains in the goal of getting rid of the callback struct. And using C99 initialization syntax makes it less likely that future patches will needlessly try to patch too many files.

[libvirt] [PATCH] freebsd: Fix build problem due to picking up the wrong libvirt.h
by Matthias Bolte 28 Jul '11

28 Jul '11

AM_GNU_GETTEXT calls AM_ICONV_LINK. AM_ICONV_LINK saves and alters CPPFLAGS, but doesn't restore it when it finds libiconv. This results in /usr/local/include ending up in the gcc command line before the include path for the local include directory. This makes gcc pick a previous installed libvirt.h instead of the correct one from the source tree. Workaround this problem by saving and restoring CPPFLAGS around the AM_GNU_GETTEXT call. --- configure.ac | 8 ++++++++ 1 files changed, 8 insertions(+), 0 deletions(-) diff --git a/configure.ac b/configure.ac index b2ba930..8f46dbd 100644 --- a/configure.ac +++ b/configure.ac @@ -2011,8 +2011,16 @@ dnl Enable building libvirtd?

qemuMigrationUpdateJobStatus (called in a loop by migration and save tasks) uses qemuDomainObjEnterMonitorWithDriver; however, that function ended up starting a nested job without releasing the driver.

Hi Thanks for the reply. I think the links that you provided show how to deal with pci devices in case the hypervisor is kvm. Please correct me if I am wrong. But I am using LXC containers.I have skimmed through the libvirt lxc driver code and found no functionality of allowing specified devices into a container exists other than currently where only hard coded devices are allowed which can be seen in the file lxc_controller.c struct cgroup_device_policy devices[] = { {'c', LXC_DEV_MAJ_MEMORY, LXC_DEV_MIN_NULL}, {'c', LXC_DEV_MAJ_MEMORY, LXC_DEV_MIN_ZERO}, {'c', LXC_DEV_MAJ_MEMORY, LXC_DEV_MIN_FULL}, {'c', LXC_DEV_MAJ_MEMORY, LXC_DEV_MIN_RANDOM}, {'c', LXC_DEV_MAJ_MEMORY, LXC_DEV_MIN_URANDOM}, {'c', LXC_DEV_MAJ_TTY, LXC_DEV_MIN_TTY}, {'c', LXC_DEV_MAJ_TTY, LXC_DEV_MIN_PTMX}, {0, 0, 0}}; Please confirm this or let me know if there is any other interface libvirt_lxc provides to allow specific pci/other devices into container.

[libvirt] RFC: API additions for enhanced snapshot support
by Eric Blake 28 Jul '11

28 Jul '11

Right now, libvirt has a snapshot API via virDomainSnapshotCreateXML, but for qemu domains, it only works if all the guest disk images are qcow2, and qemu rather than libvirt does all the work. However, it has a couple of drawbacks: it is inherently tied to domains (there is no way to manage snapshots of storage volumes not tied to a domain, even though libvirt does that for qcow2 images associated with offline qemu domains by using the qemu-img application). And it necessarily operates on all of the images associated with a domain in parallel - if any disk image is not qcow2, the snapshot fails, and there is no way to select a subset of disks to save. However, it works on both active (disk and memory state) and inactive domains (just disk state). Upstream qemu is developing a 'live snapshot' feature, which allows the creation of a snapshot without the current downtime of several seconds required by the current 'savevm' monitor command, as well as means for controlling applications (libvirt) to request that qemu pause I/O to a particular disk, then externally perform a snapshot, then tell qemu to resume I/O (perhaps on a different file name or fd from the host, but with no change to the contents seen by the guest). Eventually, these changes will make it possible for libvirt to create fast snapshots of LVM partitions or btrfs files for guest disk images, as well as to select which disks are saved in a snapshot (that is, save a crash-consistent state of a subset of disks, without the corresponding RAM state, rather than making a full system restore point); the latter would work best with guest cooperation to quiesce disks before qemu pauses I/O to that disk, but that is an orthogonal enhancement. However, my first goal with API enhancements is to merely prove that libvirt can manage a live snapshot by using qemu-img on a qcow2 image rather than the current 'savevm' approach of qemu doing all the work. Additionally, libvirt provides the virDomainSave command, which saves just the state of the domain's memory, and stops the guest. A crude libvirt-only snapshot could thus already be done by using virDomainSave, then externally doing a snapshot of all disk images associated with the domain by using virStorageVol APIs, except that such APIs don't yet exist. Additionally, virDomainSave has no flags argument, so there is no way to request that the guest be resumed after the snapshot completes. Right now, I'm proposing the addition of virDomainSaveFlags, along with a series of virStorageVolSnapshot* APIs that mirror the virDomainSnapshot* APIs. This would mean adding: /* Opaque type to manage a snapshot of a single storage volume. */ typedef virStorageVolSnapshotPtr; /* Create a snapshot of a storage volume. XML is optional, if non-NULL, it would be a new top-level element <volsnapshot> which is similar to the top-level <domainsnapshot> for virDomainSnapshotCreateXML, to specify name and description. Flags is 0 for now. */ virStorageVolSnapshotPtr virDomainSnapshotCreateXML(virStorageVolPtr vol, const char *xml, unsigned int flags); [For qcow2, this would be implemented with 'qemu-img snapshot -c', similar to what virDomainSnapshotXML already does on inactive domains. Later, we can add LVM and btrfs support, or even allow full file copies of any file type. Also in the future, we could enhance XML to take a new element that describes a relationship between the name of the original and of the snapshot, in the case where a new filename has to be created to complete the snapshot process.] /* Probe if vol has snapshots. 1 if true, 0 if false, -1 on error. Flags is 0 for now. */ int virStorageVolHasCurrentSnapshot(virStorageVolPtr vol, unsigned int flags); [For qcow2 images, snapshots can be contained within the same file and managed with qemu-img -l, but for other formats, this may mean that libvirt has to start managing externally saved data associated with the storage pool that associates snapshots with filenames. In fact, even for qcow2 it might be useful to support creation of new files backed by the previous snapshot rather than cramming multiple snapshots in one file, so we may have a use for flags to filter out the presence of single-file vs. multiple-file snapshot setups.] /* Revert a volume back to the state of a snapshot, returning 0 on success. Flags is 0 for now. */ int virStorageVolRevertToSnapsot(virStorageVolSnapshotPtr snapshot, unsigned int flags); [For qcow2, this would involve qemu-img snapshot -a. Here, a useful flag might be whether to delete any changes made after the point of the snapshot; virDomainRevertToSnapshot should probably honor the same type of flag.] /* Return the most recent snapshot of a volume, if one exists, or NULL on failure. Flags is 0 for now. */ virStorageVolSnapshotPtr virStorageVolSnapshotCurrent(virStorageVolPtr vol, unsigned int flags); /* Delete the storage associated with a snapshot (although the opaque snapshot object must still be independently freed). If flags is 0, any child snapshots based off of this one are rebased onto the parent; if flags is VIR_STORAGE_VOL_SNAPSHOT_DELETE_CHILDREN , then any child snapshots based off of this one are also deleted. */ int virStorageVolSnapshotDelete(virStorageVolSnapshotPtr snapshot, unsigned int flags); [For qcow2, this would involve qemu-img snapshot -d. For multiple-file snapshots, this would also involve qemu-img commit.] /* Free the object returned by virStorageVolSnapshot{Current,CreateXML,LookupByName}. The storage snapshot associated with this object still exists, if it has not been deleted by virStorageVolSnapshotDelete. */ int virStorageVolSnapshotFree(virStorageVolSnapshotPtr snapshot); /* Return the <volsnapshot> XML details about this snapshot object. Flags is 0 for now. */ int virStorageVolSnapshotGetXMLDesc(virStorageVolSnapshotPtr snapshot, unsigned int flags); /* Return the names of all snapshots associated with this volume, using len from virStorageVolSnapshotLen. Flags is 0 for now. */ int virStorageVolSnapshotListNames(virStorageVolPtr vol, char **names, int nameslen, unsigned int flags); [For qcow2, this involves qemu-img -l. Additionally, if virStorageVolHasCurrentSnapshot learns to filter on in-file vs. multi-file snapshots, then the same flags would apply here.] /* Get the opaque object tied to a snapshot name. Flags is 0 for now. */ virStorageVolSnapshotPtr virStorageVolSnapshotLookupByName(virStorageVolPtr vol, const char *name, unsigned int flags); /* Determine how many snapshots are tied to a volume, or -1 on error. Flags is 0 for now. */ int virStorageVolSnapshotNum(virStorageVolPtr vol, unsigned int flags); [Same flags as for virStorageVolSnapshotListNames.] /* Save a domain into the file 'to' with additional actions. If flags is 0, then xml is ignored, and this is like virDomainSave. If flags includes VIR_DOMAIN_SAVE_DISKS, then all of the associated disk images are also snapshotted, as if by virStorageVolSnapshotCreateXML; the xml argument is optional, but if present, it should be a <domainsnapshot> element with <disk> sub-elements for directions on each disk that needs a non-empty xml argument for proper volume snapshot creation. If flags includes VIR_DOMAIN_SAVE_RESUME, then the guest is resumed after the offline snapshot is complete (note that VIR_DOMAIN_SAVE_RESUME without VIR_DOMAIN_SAVE_DISKS makes little sense, as a saved state file is rendered useless if the disk images are modified before it is resumed). If flags includes VIR_DOMAIN_SAVE_QUIESCE, this requests that a guest agent quiesce disk state before the saved state file is created. */ int virDomainSaveFlags(virDomainPtr domain, const char *to, const char *xml, unsigned int flags); Also, the existing virDomainSnapshotCreateXML can be made more powerful by adding new flags and enhancing the existing XML for <domainsnapshot>. When flags is 0, the current behavior of saving memory state alongside all disks (for running domains, via savevm) or just snapshotting all disks with default settings (for offline domains, via qemu-img) is kept. If flags includes VIR_DOMAIN_SNAPSHOT_LIVE, then the guest must be running, and the new monitor commands for live snapshots are used. If flags includes VIR_DOMAIN_SNAPSHOT_DISKS_ONLY, then only the disks are snapshotted (on a running guest, this generally means they will only be crash-consistent, and will need an fsck before that disk state can be remounted), but it will shave off time by not saving memory. If flags includes VIR_DOMAIN_SNAPSHOT_QUIESCE, then this will additionally request that a guest agent quiesce disk state before the live snapshot is taken (increasing the likelihood of a stable disk, rather than a crash-consistent disk; but it requires cooperation from the guest so it is no more reliable than memballoon changes). As for the XML changes, it makes sense to snapshot just a subset of disks when you only care about crash-consistent state or if you can rely on a guest agent to quiesce the subset of disk(s) you care about, so the existing <domainsnapshot> element needs a new optional subelement to control which disks are snapshotted; additionally, this subelement will be useful for disk image formats that require additional complexity (such as a secondary file name, rather than the inline snapshot feature of qcow2). I'm envisioning something like the following: <domainsnapshot> <name>whatever</name> <disk name='/path/to/image1' snapshot='no'/> <disk name='/path/to/image2'> <volsnapshot>...</volsnapshot> </disk> </domainsnapshot> where there can be up to as many <disk> elements as there are disk <devices> in the domain xml; any domain disk not listed is given default treatment. The name attribute of <disk> is mandatory, in order to match this disk element to one of the domain disks. The snapshot='yes|no' attribute is optional, defaulting to yes, in order to skip a particular disk. The <volsnapshot> subelement is optional, but if present, it would be the same XML as is provided to the virStorageVolSnapshotCreateXML. [And since my first phase of implementation will be focused on inline qcow2 snapshots, I don't yet know what that XML will need to contain for any other type of snapshots, such as mapping out how the snapshot backing file will be named in relation to the possibly new live file.] Any feedback on this approach? Any other APIs that would be useful to add? I'd like to get all the new APIs in place for 0.9.3 with minimal qcow2 functionality, then use the time before 0.9.4 to further enhance the APIs to cover more snapshot cases but without having to add any new APIs. -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

We've made efforts at the libvirt level to have useful error reporting here, so that the cause of failure is more obvious. Also, I patched virt-manager a while ago to use a shell script to handle both RH and debian 'nc' versions. Script is here: http://git.fedorahosted.org/git?p=virt-manager.git;a=blob;f=src/virtManager… Yeah, it's complete and utter crack, but this has been a constant frustration for users, so maybe worth revisiting at the libvirt level (and hey, launching nc over ssh is kinda crack to being with :) ). Even if we solved this in a clean way by providing our own /usr/libexec/libvirt_nc binary, we'd still probably have to play shell script games over SSH to handle connecting to older libvirt (or what if libvirt_nc was installed somewhere other than libexec?) - Cole

[libvirt] Environmental Variables inside a container
by Devendra K. Modium 27 Jul '11

27 Jul '11

Hi All I am trying to pass an environmental flag to the LXC container when it is started.I found libvirt_lxc is already doing it in lxc_container.c as shown below static virCommandPtr lxcContainerBuildInitCmd(virDomainDefPtr vmDef) { char uuidstr[VIR_UUID_STRING_BUFLEN]; virCommandPtr cmd; virUUIDFormat(vmDef->uuid, uuidstr); cmd = virCommandNew(vmDef->os.init); virCommandAddEnvString(cmd, "PATH=/bin:/sbin"); virCommandAddEnvString(cmd, "TERM=linux-deva"); virCommandAddEnvPair(cmd, "LIBVIRT_LXC_UUID", uuidstr); virCommandAddEnvPair(cmd, "LIBVIRT_LXC_NAME", vmDef->name); return cmd; } But only TERM flag is getting visible inside the container not remaining. Does it depends on how /sbin/init is receiving them? Is /sbin/init only recognizing TERM flag. If so what is intention of sending remaining flags in current libvirt. Please let me know if there is any elegant way to send environmental variable to container. Thanks for your time. Regards Devendra

[libvirt] Add support for image write mode in virtualbox driver
by Boris FELD 27 Jul '11

27 Jul '11

Hi everyone, We currently using libvirt for PYTI GSOC Project (it works very well!) and we encounter a problem. We use VM with two disk images, one which must to be snapshoted/rollbacked and the other one which must be not. We use VirtualBox as hypervisor and to do so, VirtualBox define "Special image write modes" (http://www.virtualbox.org/manual/ch05.html#hdimagewrites) What we need is to set the type of one image to "writethrough". This information seems defined in VM config file. For instance: <HardDisk uuid="{402aef07-4df8-4518-831c-eeb9ae2a32d2}" location="/home/boris/VirtualBox VMs/PYTI.vdi" format="VDI" type="Normal"/> <HardDisk uuid="{63acf6d9-b7db-4d8d-8389-1276c3d500bb}" location="/home/boris/VirtualBox VMs/adhock.vdi" format="VDI" type="Writethrough"/> I found two pages mentioning the type of medium, this one: http://www.virtualbox.org/sdkref/_virtual_box_8idl.html#b4abb9d1b9e44b997d1… and this one: http://www.virtualbox.org/sdkref/interface_i_medium_attachment.html. Hope it will help. Cheers, FELD Boris

[libvirt] [PATCH 00/10] Rollback migration when libvirtd restarts

This is the rest of the original 19 patch series updated with some bugfixes and rebased on current master, which is also available at https://gitorious.org/~jirka/libvirt/jirka-staging/commits/migration-recove… I didn't manage to run this through the libvirt-tck migration test but I did some additional testing with the following combinations of libvirt (current contains this series): source destination client ------------------------------------------- current current current current current 0.9.2-1.el6 current 0.9.2-2.fc15 current 0.9.2-2.fc15 current 0.9.2-1.el6 In all combinations I did - normal migration from src to dst - normal migration back - p2p migration from src to dst - p2p migration back To test failure recovery, I aborted the migration or libvirtd deamons at various places. All this was done with a single running domain without restarting it.

[libvirt] [PATCHv3 1/2] conf: add <listen> subelement to domain <graphics> element
by Laine Stump 27 Jul '11

27 Jul '11

Once it's plugged in, the <listen element will be an optional replacement for the "listen", "port", "tlsPort", and "autoport" attributes that graphics elements already have. If the <listen> type='address', it will have an attribute called 'address' which will contain an IP address or dns name that the guest's display server should listen on. If, however, type='network', the <listen> element should have an attribute called 'network' that will be set to the name of a network configuration to get the IP address from. * docs/schemas/domain.rng: updated to allow the <listen> element * docs/formatdomain.html.in: document the <listen> element and its attributes. * src/conf/domain_conf.[hc]: 1) The domain parser, formatter, and data structure are modified to support 0 or more <listen> subelements to each <graphics> element. The old style "legacy" attributes are also still accepted, and will be stored internally just as if they were a separate <listen> element. On output (i.e. format), the first <listen> element will be duplicated in the legacy attributes of the <graphic> element. 2) The following attributes have been removed from the unions in virDomainGRaphicsDef for graphics types vnc, rdp, and spice: listen port tlsPort autoport These attributes are all present in the <listen> subelement (aka virDomainGraphicsListenDef) 3) Several helper functions were written to provide simple access (both Get and Set) to the listen elements. * src/libvirt_private.syms: export the listen helper functions * src/qemu/qemu_command.c, src/qemu/qemu_driver.c, src/qemu/qemu_hotplug.c, src/qemu/qemu_migration.c, src/qemu/qemu_process.c, src/vbox/vbox_tmpl.c, src/vmx/vmx.c, src/xenxs/xen_sxpr.c, src/xenxs/xen_xm.c Modify all these files to use the listen helper functions rather than directly referencing the (now missing) listen, port, tlsPort, and autoport attributes. There can be multiple <listen> elements to a single <graphics>, but the drivers all currently only support one, so all replacements of direct access with a helper function indicate index "0". * tests/* - only 3 of these are new files added explicitly to test the new <listen> element. All the others have been modified to reflect the fact that any "legacy" attributes passed in to the domain parse will be saved in a <listen> element (i.e. one of the virDomainGraphicsListenDefs), and during the domain format function, both the <listen> element as well as the legacy attributes will be output. --- docs/formatdomain.html.in | 70 ++ docs/schemas/domain.rng | 46 ++

[libvirt] gnulib compiler warning detection broken on RHEL5 autoconf
by Daniel P. Berrange 27 Jul '11

27 Jul '11

I was wondering why I didn't see any compile warnings from the broken gnutls code on RHEL5 when I noticed that we were building without any compiler warning flags at all. It seems configure fails on RHEL5 vintage autoconf checking whether compiler handles -Wall... ./configure: line 75468: ${$as_gl_Warn+set}: bad substitution I'm guessing it is the gl_WARN_ADD() macro that is at fault somehow.

[libvirt] [PATCH] bandwidth: Integrate bandwidth into portgroups
by Michal Privoznik 27 Jul '11

27 Jul '11

Every DomainNetDef has a bandwidth, as does every portgroup. Whenever a DomainNetDef of type NETWORK is about to be used, a call is made to networkAllocateActualDevice(). This function chooses the "best" bandwidth object and places it in the DomainActualNetDef. >From that point on, whenever some code needs to use the bandwidth data for the interface, it's retrieved with virDomainNetGetActualBandwidth(), which will always return the "best" info as determined in the previous step. --- docs/formatnetwork.html.in | 2 + src/conf/domain_conf.c | 25 ++++++++++++++++++- src/conf/domain_conf.h | 3 ++ src/conf/network_conf.c | 10 +++++++ src/conf/network_conf.h | 1 + src/libvirt_private.syms | 1 + src/network/bridge_driver.c | 19 +++++++++++++- src/util/network.c | 56 +++++++++++++++++++++++++++++++++++++++++++ src/util/network.h | 2 + 9 files changed, 116 insertions(+), 3 deletions(-) diff --git a/docs/formatnetwork.html.in b/docs/formatnetwork.html.in index f0ff703..ddfa77c 100644 --- a/docs/formatnetwork.html.in +++ b/docs/formatnetwork.html.in @@ -129,6 +129,8 @@ numbers, The units for <code>average</code> and <code>peak</code> attributes are kilobytes per second, and for the <code>burst</code> just kilobytes.

[libvirt] [PATCH] Fix race in ref counting when handling RPC jobs
by Daniel P. Berrange 26 Jul '11

From: "Daniel P. Berrange" <berrange(a)redhat.com> When an incoming RPC message is ready for processing, virNetServerClientDispatchRead() will invoke the 'dispatchFunc' callback. This is set to virNetServerDispatchNewMessage This function puts the message + client in a queue for processing by the thread pool. The thread pool worker function is virNetServerHandleJob The first thing this does is acquire an extra reference on the 'client'. Unfortunately, between the time the message+client are put on the thread pool queue, and the time the worker runs, the client object may have had its last reference removed. We clearly need to add the reference to the client object before putting the client on the processing queue * src/rpc/virnetserverclient.c: Add a reference to the client when invoking the dispatch function * src/rpc/virnetserver.c: Don't acquire a reference to the client when in the worker thread --- src/rpc/virnetserver.c | 2 -- src/rpc/virnetserverclient.c | 2 ++ 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/rpc/virnetserver.c b/src/rpc/virnetserver.c index 2b9dd4d..c93c3f8 100644 --- a/src/rpc/virnetserver.c +++ b/src/rpc/virnetserver.c @@ -131,8 +131,6 @@ static void virNetServerHandleJob(void *jobOpaque, void *opaque) virNetServerProgramPtr prog = NULL; size_t i; - virNetServerClientRef(job->client); - virNetServerLock(srv); VIR_DEBUG("server=%p client=%p message=%p", srv, job->client, job->msg); diff --git a/src/rpc/virnetserverclient.c b/src/rpc/virnetserverclient.c index 317d59c..3c0dba8 100644 --- a/src/rpc/virnetserverclient.c +++ b/src/rpc/virnetserverclient.c @@ -763,10 +763,12 @@ readmore: /* Send off to for normal dispatch to workers */ if (msg) { + client->refs++; if (!client->dispatchFunc || client->dispatchFunc(client, msg, client->dispatchOpaque) < 0) { virNetMessageFree(msg); client->wantClose = true; + client->refs--; return; } } -- 1.7.6

We apply cpu bandwidth at the vcpu and the vm group level, so we must ensure that max(child_quota) <= parent_quota when we modify cpu bandwidth. --- src/qemu/qemu_cgroup.c | 38 ++++++++++------- src/qemu/qemu_driver.c | 103 ++++++++++++++++++++++++++++++++++++----------- 2 files changed, 101 insertions(+), 40 deletions(-) diff --git a/src/qemu/qemu_cgroup.c b/src/qemu/qemu_cgroup.c index d6e4cbc..2a10bd2 100644 --- a/src/qemu/qemu_cgroup.c +++ b/src/qemu/qemu_cgroup.c @@ -435,6 +435,7 @@ int qemuSetupCgroupForVcpu(struct qemud_driver *driver, virDomainObjPtr vm) unsigned int i; unsigned long long period = vm->def->cputune.period; long long quota = vm->def->cputune.quota; + long long vm_quota = 0; if (driver->cgroup == NULL) return 0; /* Not supported, so claim success */ @@ -447,26 +448,31 @@ int qemuSetupCgroupForVcpu(struct qemud_driver *driver, virDomainObjPtr vm) goto cleanup; } + /* Set cpu bandwidth for the vm */ + if (period || quota) { + if (qemuCgroupControllerActive(driver, VIR_CGROUP_CONTROLLER_CPU)) { + /* Ensure that we can multiply by vcpus without overflowing. */ + if (quota > LLONG_MAX / vm->def->vcpus) { + virReportSystemError(EINVAL, + _("%s"), + "Unable to set cpu bandwidth quota"); + goto cleanup; + } + + if (quota > 0) + vm_quota = quota * vm->def->vcpus; + else + vm_quota = quota; + if (qemuSetupCgroupVcpuBW(cgroup, period, vm_quota) < 0) + goto cleanup; + } + } + if (priv->nvcpupids == 0 || priv->vcpupids[0] == vm->pid) { /* If we does not know VCPU<->PID mapping or all vcpu runs in the same * thread, we cannot control each vcpu. */ - if (period || quota) { - if (qemuCgroupControllerActive(driver, VIR_CGROUP_CONTROLLER_CPU)) { - /* Ensure that we can multiply by vcpus without overflowing. */ - if (quota > LLONG_MAX / vm->def->vcpus) { - virReportSystemError(EINVAL, - _("%s"), - "Unable to set cpu bandwidth quota"); - goto cleanup; - } - - if (quota > 0) - quota *= vm->def->vcpus; - if (qemuSetupCgroupVcpuBW(cgroup, period, quota) < 0) - goto cleanup; - } - } + virCgroupFree(&cgroup); return 0; } diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 5df58b1..52e5d69 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -6051,43 +6051,98 @@ qemuSetVcpusBWLive(virDomainObjPtr vm, virCgroupPtr cgroup, qemuDomainObjPrivatePtr priv = vm->privateData; virCgroupPtr cgroup_vcpu = NULL; int rc; + long long vm_quota = 0; + long long old_quota = 0; + unsigned long long old_period = 0; if (period == 0 && quota == 0) return 0; - if (priv->nvcpupids == 0 || priv->vcpupids[0] == vm->pid) { - /* If we does not know VCPU<->PID mapping or all vcpu runs in the same - * thread, we cannot control each vcpu. - */ - /* Ensure that we can multiply by vcpus without overflowing. */ - if (quota > LLONG_MAX / vm->def->vcpus) { - virReportSystemError(EINVAL, - _("%s"), - "Unable to set cpu bandwidth quota"); - goto cleanup; - } + /* Ensure that we can multiply by vcpus without overflowing. */ + if (quota > LLONG_MAX / vm->def->vcpus) { + virReportSystemError(EINVAL, + _("%s"), + "Unable to set cpu bandwidth quota"); + goto cleanup; + } + + if (quota > 0) + vm_quota = quota * vm->def->vcpus; + else + vm_quota = quota; - if (quota > 0) - quota *= vm->def->vcpus; - return qemuSetupCgroupVcpuBW(cgroup, period, quota); + rc = virCgroupGetCpuCfsQuota(cgroup, &old_quota); + if (rc < 0) { + virReportSystemError(-rc, "%s", + _("unable to get cpu bandwidth tunable")); + goto cleanup; } - for (i = 0; i < priv->nvcpupids; i++) { - rc = virCgroupForVcpu(cgroup, i, &cgroup_vcpu, 0); - if (rc < 0) { - virReportSystemError(-rc, - _("Unable to find vcpu cgroup for %s(vcpu:" - " %d)"), - vm->def->name, i); - goto cleanup; + rc = virCgroupGetCpuCfsPeriod(cgroup, &old_period); + if (rc < 0) { + virReportSystemError(-rc, "%s", + _("unable to get cpu bandwidth period tunable")); + goto cleanup; + } + + /* + * If quota will be changed to a small value, we should modify vcpu's quota + * first.

[libvirt] [PATCH 1/2] Allow certificate sanity checking to be disabled

From: "Daniel P. Berrange" <berrange(a)redhat.com> When libvirtd starts it it will sanity check its own certs, and before libvirt clients connect to a remote server they will sanity check their own certs.

There is no strong reason to need to do this, other than to bypass possible libvirt bugs in sanity checking, or for testing purposes. libvirt.conf gains tls_no_sanity_certificate parameter to go along with tls_no_verify_certificate.

[libvirt] [PATCH] util: change virFile*Pid functions to return < 0 on failure
by Laine Stump 25 Jul '11

25 Jul '11

Although most functions in libvirt return 0 on success and < 0 on failure, there are a few functions lingering around that return errno (a positive value) on failure, and sometimes code calling those functions incorrectly assumes the <0 standard. I noticed one of these the other day when auditing networkStartDhcpDaemon after Guido Gunther found a place where success was improperly returned on failure (that patch has been acked and is pending a push). The problem was that it expected the return value from virFileReadPid to be < 0 on failure, but it was actually positive (it was also neglected to set the return code in this case, similar to the bug found by Guido). This all led to the fact that *all* of the virFile*Pid functions in util.c are returning errno on failure. This patch remedies that problem by changing them all to return -errno on failure, and makes any necessary changes to callers of the functions. (In the meantime, I also properly set the return code on failure of virFileReadPid in networkStartDhcpDaemon). --- src/lxc/lxc_controller.c | 6 +++--- src/lxc/lxc_driver.c | 4 ++-- src/network/bridge_driver.c | 5 +++-- src/qemu/qemu_process.c | 2 +- src/util/command.c | 2 +- src/util/util.c | 30 +++++++++++++++--------------- tests/commandtest.c | 4 ++-- 7 files changed, 27 insertions(+), 26 deletions(-) diff --git a/src/lxc/lxc_controller.c b/src/lxc/lxc_controller.c index 7eda7ef..99d9467 100644 --- a/src/lxc/lxc_controller.c +++ b/src/lxc/lxc_controller.c @@ -947,8 +947,8 @@ int main(int argc, char *argv[]) goto cleanup;

[libvirt] [PATCH v4 0/7] Add support for setting QoS
by Michal Privoznik 25 Jul '11

25 Jul '11

This patch series add support for setting traffic shaping and policing on both domain's interface and network's virtual bridge. Basically, this is done via 'tc' from iproute2 package. For shaping is HTB used, for policing we need u32 match selector. Both should be available in RHEL-6 kernel. How this works: On an virtual interface which has limits defined a root qdisc are replaced. Ingress root for outbound traffic shaping and egress for inbound. Basically, in inbound traffic policing is applied, on outbound shaping. New qdiscs are set to limit the traffic to rate set in XML. For shaping it is possible to set the size of buffer. Accepted values for rate, peak and burst are integer numbers. Units are kilobytes per second for rate or kilobytes for size. Supported devices are VIR_DOMAIN_NET_TYPE_NETWORK, VIR_DOMAIN_NET_TYPE_BRIDGE and VIR_DOMAIN_NET_TYPE_DIRECT. diff to v3: -Laine's review included diff to v2: -Jirka's review included diff to v1: -rebase to current HEAD -add support for macvtap devices Michal Privoznik (7): bandwidth: Define schema and create documentation bandwidth: Declare internal structures bandwidth: Add parsing and free functions bandwidth: Create format functions bandwidth: Implement functions to enable and disable QoS bandwidth: Add test cases for network bandwidth: Add domain schema test suite configure.ac | 4 + docs/formatdomain.html.in | 34 +++ docs/formatnetwork.html.in | 30 ++ docs/schemas/domain.rng | 3 + docs/schemas/network.rng | 3 + docs/schemas/networkcommon.rng | 48 +++ libvirt.spec.in | 2 +- src/conf/domain_conf.c | 8 + src/conf/domain_conf.h | 1 + src/conf/network_conf.c | 10 + src/conf/network_conf.h | 1 + src/libvirt_private.syms | 5 + src/network/bridge_driver.c | 18 ++ src/qemu/qemu_command.c | 11 +- src/util/macvtap.c | 12 +- src/util/macvtap.h | 3 +- src/util/network.c | 380 +++++++++++++++++++++++++ src/util/network.h | 22 ++ tests/domainschemadata/domain-bandwidth.xml | 72 +++++ tests/networkxml2xmlin/bandwidth-network.xml | 16 + tests/networkxml2xmlout/bandwidth-network.xml | 16 + tests/networkxml2xmltest.c | 1 + 22 files changed, 696 insertions(+), 4 deletions(-) create mode 100644 tests/domainschemadata/domain-bandwidth.xml create mode 100644 tests/networkxml2xmlin/bandwidth-network.xml create mode 100644 tests/networkxml2xmlout/bandwidth-network.xml -- 1.7.5.rc3

[libvirt] libvirt.org outage
by Eric Blake 25 Jul '11

25 Jul '11

libvirt.org appears to be down, possibly for as long as the entire weekend. While that doesn't help anyone trying to browse the online documentation, we at least have the benefit of git being a distributed version control system. For those who would like to track what will be pushed to upstream libvirt.git once it is back online, I've got my personal repo available for the purpose. Assuming that I caught things just before the power outage, then it will be a trivial sync to get everything from my master branch back upstream once things are back to normal. Browse the latest state at: http://repo.or.cz/w/libvirt/ericb.git Track the latest state of upstream patches with: git pull git://repo.or.cz/libvirt/ericb.git master Propose your own patches for me to merge in to the master branch (the mob branch has no push restrictions - anyone can push there, but that also means that anyone can rewind history there, so let me know the commit id of anything that you have pushed there that I should then sync into the master branch): git push mob@repo.or.cz:/srv/git/libvirt/ericb.git +HEAD:mob Feel free to ask questions on list or on irc://irc.oftc.net/virt if you want to coordinate on bleeding-edge development this weekend. -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

[libvirt] [PATCHv2 0/4] support the listenNetwork attribute in <graphics>
by Laine Stump 25 Jul '11

25 Jul '11

This patch series resolves the following bug: https://bugzilla.redhat.com/show_bug.cgi?id=703851 In short, it implements support for a new "listenNetwork" attribute in the domain's <graphics> element. When listenNetwork is specified, libvirt will look for a network of that name (from the networks that can be created within libvirt), and derive a listen address from the physical interface used to connect that network to the outside world. (More details are given in each commit message). This is V2. The main differences from V1 are: 1) everything was rebased 2) I eliminated #if WITH_NETWORK in the .c files by defining the one missing function as static inline when WITH_NETWORK is false. This series is meant to be applied on top of the "network physical device abstraction" patch series I sent a couple hours ago: https://www.redhat.com/archives/libvir-list/2011-July/msg01294.html Don't attempt to apply it by itself!

But even if you add new features to qemu to avoid needing this in the future, it doesn't change the past - libvirt will always have to know how to parse image files understood by older qemu, and so as long as libvirt already knows how to do that parsing, we might as well take advantage of it. Besides, I feel that having a well-documented file format, so that independent applications can both parse the same file with the same semantics by obeying the file format specification, is a good design goal. > >> It would be nice if libvirt had a way to pass fds for every disk and >> backing file up front; then, SELinux can work around the lack of NFS >> per-file labelling by blocking open() in qemu.

As nice as that sentiment is, it will never fly, because it would be a regression in current behavior. The whole reason that the virt_use_nfs SELinux bool exists is that some people are willing to make the partial security tradeoff. Besides, the use of sVirt via SELinux is more than just open() protection - while the current virt_use_nfs bool makes NFS less secure than otherwise possible, it still gives some nice guarantees to the rest of the qemu process such as passthrough accesses to local pci devices. Just because it is currently not as secure to mix NFS shared storage with backing files doesn't stop some people from wanting to do it [in fact, that's my current development setup - I use qcow2 images on NFS shared storage, keep SELinux enabled, and enable the virt_use_nfs bool]. This discussion is about adding enhancements that make SELinux even more powerful when using NFS shared storage, by adding fd passing (whether libvirt parses in advance, or whether qemu raises an event and requires feedback from libvirt), and not about crippling the existing capability to use the virt_use_nfs selinux bool. -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
