[libvirt] [PATCH v3] virsh: Add more human-friendly output of domblkstat command
by Peter Krempa 07 Sep '11

07 Sep '11

Users of virsh complain that output of the domblkstat command is not intuitive enough. This patch adds explanation of fields returned by this command to the help section for domblkstat and the man page of virsh. Also a switch --human is added for domblkstat that prints the fields with more descriptive texts. https://bugzilla.redhat.com/show_bug.cgi?id=731656 Changes to v2: - Modify for new fields in virDomainBlockStatsFlags Changes to v1: - Rebase to current head --- tools/virsh.c | 114 ++++++++++++++++++++++++++++++++++++++++++++++-------- tools/virsh.pod | 16 +++++++- 2 files changed, 112 insertions(+), 18 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index 629233f..458252b 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -1054,16 +1054,46 @@ cleanup: */ static const vshCmdInfo info_domblkstat[] = { {"help", N_("get device block stats for a domain")}, - {"desc", N_("Get device block stats for a running domain.")}, + {"desc", N_("Get device block stats for a running domain.\n\n" + " Explanation of fields:\n" + " rd_req - count of read operations (old format)\n" + " rd_operations - count of read operations (new format)\n" + " rd_bytes - count of read bytes\n" + " rd_total_times - total time read operations took\n" + " wr_req - count of write operations (old format)\n" + " wr_operations - count of write operations (new format)\n" + " wr_bytes - count of written bytes\n" + " flush_operations - count of flush operations\n" + " flush_total_times - total time flush operations took\n" + " errs - error count")}, {NULL,NULL} };

[libvirt] [RFC] netlink monitor thread
by D. Herrendoerfer 07 Sep '11

07 Sep '11

Hello, I'm trying to get libvirt to recognize port profile disassociations, i.e. when the switch removes a port profile because lldpad has unexpectedly quit or the profile has been changed in the switches profile database, or when something went wrong otherwise. My take on this for testing was to have an external deamon log port profiles and changes to them, and tell lldpad to set them again if needed. But this is not really practical. I would like to find a way to have the libvitrd monitor netlink and take appropriate measures if, for example, a port profile is removed unexpectedly, that is: to call the VMs network setup again if macvtap/VEPA is used. There would be other benefits, like the detection if a link goes down on a used interface, or a device is unexpectedly configured down by another component. Looking at the deamon code I'm unclear on how to do this properly, this is a very linux specific thing, and the asynchronous nature of the request handling makes starting the monitor thread later on difficult. Thoughts, ideas ? D. Herrendoerfer

[libvirt] [PATCH] esx: Support folders in the path of vpx:// connection URIs
by Matthias Bolte 06 Sep '11

06 Sep '11

Allow the datacenter and compute resource parts of the path to be prefixed with folders. Therefore, the way the path is parsed has changed. Before, it was split in 2 or 3 items and the items' meanings were determined by their positions. Now the path can have 2 or more items and the the vCenter server is asked whether a folder, datacenter of compute resource with the specified name exists at the current hierarchy level. Before the datacenter and compute resource lookup automatically traversed folders during lookup. This is logic got removed and folders have to be specified explicitly. The proper datacenter path including folders is now used when accessing a datastore over HTTPS. This makes virsh dumpxml and define work for datacenters in folders. https://bugzilla.redhat.com/show_bug.cgi?id=732676 --- docs/drvesx.html.in | 10 ++- src/esx/esx_driver.c | 14 ++-- src/esx/esx_util.c | 19 +--- src/esx/esx_util.h | 1 + src/esx/esx_vi.c | 223 ++++++++++++++++++++++++++++++++++------ src/esx/esx_vi_generator.input | 4 + 6 files changed, 215 insertions(+), 56 deletions(-) diff --git a/docs/drvesx.html.in b/docs/drvesx.html.in index da9d2a1..aa8ecd4 100644 --- a/docs/drvesx.html.in +++ b/docs/drvesx.html.in @@ -56,7 +56,7 @@ esx://example-esx.com/?no_verify=1 (ESX over HTTPS, but doesn't verify the s URIs have this general form (<code>[...]</code> marks an optional part). </p> <pre> -type://[username@]hostname[:port]/[datacenter[/cluster]/server][?extraparameters] +type://[username@]hostname[:port]/[[folder/...]datacenter/[folder/...][cluster/]server][?extraparameters] </pre> <p> The <code>type://</code> is either <code>esx://</code> or @@ -80,6 +80,14 @@ type://[username@]hostname[:port]/[datacenter[/cluster]/server][?extraparameters <pre> vpx://example-vcenter.com/dc1/cluster1/example-esx.com </pre> + <p> + Datacenters and clusters can be organized in folders, those have to be + specified as well.

Users of virsh complain that output of the domblkstat command is not intuitive enough. This patch adds explanation of fields returned by this command to the help section for domblkstat and the man page of virsh. Also a switch --human is added for domblkstat that prints the fields with more descriptive texts. https://bugzilla.redhat.com/show_bug.cgi?id=731656 Changes to v1: -Rebased to current head --- tools/virsh.c | 52 +++++++++++++++++++++++++++++++++++++++++----------- tools/virsh.pod | 11 ++++++++++- 2 files changed, 51 insertions(+), 12 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index c7240e5..09337cb 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -1054,13 +1054,21 @@ cleanup: */ static const vshCmdInfo info_domblkstat[] = { {"help", N_("get device block stats for a domain")}, - {"desc", N_("Get device block stats for a running domain.")}, + {"desc", N_("Get device block stats for a running domain.\n\n" + " Explanation of fields:\n" + " rd_req - count of read requests\n" + " rd_bytes - count of read bytes\n" + " wr_req - count of write requests\n" + " wr_bytes - count of written bytes\n" + " errs - error count")}, {NULL,NULL} }; static const vshCmdOptDef opts_domblkstat[] = { {"domain", VSH_OT_DATA, VSH_OFLAG_REQ, N_("domain name, id or uuid")}, {"device", VSH_OT_DATA, VSH_OFLAG_REQ, N_("block device")}, + {"human", VSH_OT_BOOL, 0, N_("print a more human readable output")}, + {NULL, 0, 0, NULL} }; @@ -1070,6 +1078,7 @@ cmdDomblkstat (vshControl *ctl, const vshCmd *cmd) virDomainPtr dom; const char *name = NULL, *device = NULL; struct _virDomainBlockStats stats; + int humanReadable = vshCommandOptBool(cmd, "human"); if (!vshConnectionUsability (ctl, ctl->conn)) return false; @@ -1088,20 +1097,41 @@ cmdDomblkstat (vshControl *ctl, const vshCmd *cmd) return false; } - if (stats.rd_req >= 0) - vshPrint (ctl, "%s rd_req %lld\n", device, stats.rd_req); + if (humanReadable) { + /* human friendly output */ + vshPrint(ctl, N_("Device: %s\n"), device); + + if (stats.rd_req >= 0) + vshPrint (ctl, N_("read request count: %lld\n"), stats.rd_req); + + if (stats.rd_bytes >= 0) + vshPrint (ctl, N_("number of read bytes: %lld\n"), stats.rd_bytes); + + if (stats.wr_req >= 0) + vshPrint (ctl, N_("write request count: %lld\n"), stats.wr_req); - if (stats.rd_bytes >= 0) - vshPrint (ctl, "%s rd_bytes %lld\n", device, stats.rd_bytes); + if (stats.wr_bytes >= 0) + vshPrint (ctl, N_("number of written bytes: %lld\n"), stats.wr_bytes); - if (stats.wr_req >= 0) - vshPrint (ctl, "%s wr_req %lld\n", device, stats.wr_req); + if (stats.errs >= 0) + vshPrint (ctl, N_("error count: %lld\n"), stats.errs); + } else { + /* script friendly output */ + if (stats.rd_req >= 0) + vshPrint (ctl, "%s rd_req %lld\n", device, stats.rd_req); + + if (stats.rd_bytes >= 0) + vshPrint (ctl, "%s rd_bytes %lld\n", device, stats.rd_bytes); - if (stats.wr_bytes >= 0) - vshPrint (ctl, "%s wr_bytes %lld\n", device, stats.wr_bytes); + if (stats.wr_req >= 0) + vshPrint (ctl, "%s wr_req %lld\n", device, stats.wr_req); - if (stats.errs >= 0) - vshPrint (ctl, "%s errs %lld\n", device, stats.errs); + if (stats.wr_bytes >= 0) + vshPrint (ctl, "%s wr_bytes %lld\n", device, stats.wr_bytes); + + if (stats.errs >= 0) + vshPrint (ctl, "%s errs %lld\n", device, stats.errs); + } virDomainFree(dom); return true; diff --git a/tools/virsh.pod b/tools/virsh.pod index 30c0721..c333b2a 100644 --- a/tools/virsh.pod +++ b/tools/virsh.pod @@ -501,10 +501,19 @@ be lost once the guest stops running, but the snapshot contents still exist, and a new domain with the same name and UUID can restore the snapshot metadata with B<snapshot-create>. -=item B<domblkstat> I<domain> I<block-device> +=item B<domblkstat> I<domain> I<block-device> [I<--human>] Get device block stats for a running domain. +Use I<--human> for a more human readable output. + +B<Explanation of fields:> + rd_req - count of read requests + rd_bytes - count of read bytes + wr_req - count of write requests + wr_bytes - count of written bytes + errs - error count + =item B<domifstat> I<domain> I<interface-device> Get network interface stats for a running domain. -- 1.7.3.4

[libvirt] [PATCH RFC 0/2] XML: Improve XML parse error reporting
by Peter Krempa 06 Sep '11

06 Sep '11

First patch modifies the error reporting function on parse errors of XML files. A new, more informative message is presented to the user, containing filename of the offending file, error description and context of the error in libxml2 style. Second patch changes default filenames used while parsing XML strings in memory to NULL, so that the error reporting function does not print bougus filename. src/conf/domain_conf.c - change "domain.xml" to NULL src/security/virt-aa-helper.c - change "domain.xml" to NULL src/util/xml.c - modify error reporting function Peter Krempa (2): XML: Improve XML parsing error messages XML: Suppress printing "domain.xml" for parse errors on XML strings src/conf/domain_conf.c | 2 +- src/security/virt-aa-helper.c | 2 +- src/util/xml.c | 88 +++++++++++++++++++++++++++++++++++------ 3 files changed, 78 insertions(+), 14 deletions(-) -- 1.7.3.4

[libvirt] [PATCH v3 0/5] Virtual interface link state modification
by Peter Krempa 06 Sep '11

06 Sep '11

This patchset adds the ability for libvirt users to control interface link state of the virtual network devices provided by hypervisors. Modification of the link state is accomplished by adding a new XML element <link state"up"> or "down" to the domain XML. The corresponding network interface is thereafter initialised with the desired state. Live modification of the link state is achieved by calling virDomainUpdateDeviceFlags containing a modified interface configuration. Yet, users may modify only link state of an interface. This feature allows propagation of network topology changes to guests, testing scenarios in complex virtual networks, etc ... Future upgrade: - add support for VirtualBox Modifications to v2: - Rebase to curent HEAD Modifications to v1: - use virUpdateDeviceFlags instead of dedicated API - incorporate helpful comments by Eric Blake https://bugzilla.redhat.com/show_bug.cgi?id=643373 Peter Krempa (5): link-state: util: Add equality comparision functions for structures link-state: conf: Add element to XML for controling link state link-state: qemu: Add monitor handling for link state modification link-state: qemu: Add net intf modification to virUpdateDeviceFlags link-state: virsh: Add wrapper commands for changing link state docs/formatdomain.html.in | 21 +++ docs/schemas/network.rng | 11 ++ src/conf/domain_conf.c | 24 ++++ src/conf/domain_conf.h | 11 ++ src/qemu/qemu_driver.c | 24 ++++ src/qemu/qemu_hotplug.c | 176 ++++++++++++++++++++++++++ src/qemu/qemu_hotplug.h | 8 ++ src/qemu/qemu_monitor.c | 19 +++ src/qemu/qemu_monitor.h | 4 + src/qemu/qemu_monitor_json.c | 23 ++++ src/qemu/qemu_monitor_json.h | 4 + src/qemu/qemu_monitor_text.c | 46 +++++++ src/qemu/qemu_monitor_text.h | 4 + src/qemu/qemu_process.c | 47 +++++++- src/util/network.c | 62 +++++++++ src/util/network.h | 5 + tools/virsh.c | 286 ++++++++++++++++++++++++++++++++++++++++++ tools/virsh.pod | 11 ++ 18 files changed, 785 insertions(+), 1 deletions(-) -- 1.7.3.4

[libvirt] [PATCH 0/8 v2] Report disk latency info
by Osier Yang 06 Sep '11

06 Sep '11

This patch series introduces a new API to report the disk latency related information, which is supported by upstream QEMU just a few days ago (commit c488c7f649, Thu Aug 25). Per previous dicussion on the ABI compatiblity, and API design principle, the new API is defined with style: int virDomainBlockStatsFlags (virDomainPtr dom, const char *path, virTypeParamsPtr params, int *nparams, unsigned int flags) V1 - V2: * Use virTypedParameter instead of creating a new struct for the new API. * Update comments for the API, (Eric's suggestion). [PATCH 1/8] latency: Define new public API and structure [PATCH 2/8] latency: Define the internal driver callback [PATCH 3/8] latency: Implemente the public API [PATCH 4/8] latency: Wire up the remote protocol [PATCH 5/8] latency: Update monitor functions for new latency fields [PATCH 6/8] latency: Implemente internal API for qemu driver [PATCH 7/8] latency: Expose the new API for Python binding [PATCH 8/8] latency: Update cmdBlkStats to use new API Regards, Osier

[libvirt] [PATCH 0/3] Libvirt RPC dispatching and unresponsive QEMU
by Michal Privoznik 05 Sep '11

05 Sep '11

If there is an unresponsive qemu process and libvirt access it's monitor, it will not get any response and this thread will block indefinitely, until the qemu process resumes or it's destroyed. If users continues executing APIs against that domain, libvirt will run out of worker threads and hangs (if those APIs will access monitor as well). Although, they will timeout in approx 30 seconds, which will free some workers, during that time is libvirt unable to process any request. Even worse - if the number of unresponsive qemu exceeds the size of worker thread pool, libvirt will hangs forever, and even restarting the daemon will not make it any better. This patch set heals the daemon on several levels, so nothing from written above will cause it to hangs: 1. RPC dispatching - all APIs are now annotated as 'high' or 'low' priority. Then a special thread pool is created. Low priority APIs will be still placed into usual pool, but high priority can be placed into this new pool if the former has no free worker. Which APIs should be marked high and which low? The splitting presented here is my guessing. It is not something written in stone, but from the logic of things it is not safe to annotate any API which is NOT guaranteed to end in reasonable small time as high priority call. 2. Job queue size limit - this sets bound on the number of threads blocked by a stuck qemu. Okay, there exists timeout on this, but if user application continue dispatching low priority calls it can still consume all (low priority) worker threads and therefore affect other users/VMs. Even if they timeout in approx 30 secs. 3. Run monitor re-connect in a separate thread per VM. If libvirtd is restarted, it tries to reconnect to all running qemu processes. This is potentially risky - one stuck qemu block daemon startup. However, putting the monitor startup code into one thread per VM allows libvirtd to startup, accept client connections and work with all VMs which monitor was successfully re-opened. Unresponsive qemu will hold job until we open the monitor. So clever user application can destroy such domain. All APIs requiring job will just fail in acquiring lock.

You are right, but we would want to have the option to prevent that from happening in case we wouldn't want to allow it. We can make the ability to migrate between different network types configurable, and we would like an easy way to tell libvirt - "please allow/don't allow it". > > > So, in the networks at the host level you will have: > > <network type='direct'> > > <name>red-network</name> > > <source mode='vepa'> > > <pool> > > <interface> > > <name>eth0</name> > > ..... > > </interface> > > <interface> > > <name>eth4</name> > > ..... > > </interface> > > <interface> > > <name>eth18</name> > > ..... > > </interface> > > </pool> > > </source> > > </network> > > > > And in the guest you will have (for vepa): > > <interface type='network'> > > <source network='red-network'/> > > <virtualport type="802.1Qbg"> > > <parameters managerid="11" typeid="1193047" typeidversion="2" > > instanceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f"/> > > </virtualport> > > </interface> > > > > Or (for vnlink): > > <interface type='network'> > > <source network='red-network'/> > > <virtualport type="802.1Qbh"> > > <parameters profile_name="profile1"/> > > </virtualport> > > </interface> > > This illustrates the problem I was wondering about - in your example > it > would not be possible for the guest to migrate from the host using a > vepa switch to the host using a vnlink switch (and it would be > possible You are right.

What I meant to say in that is that we would like to have the ability to say if an attribute must me used, or not. The issues you mention are indeed interesting. I'm cc-ing libvirt-list to see what other people think. Putting it on the guest will indeed make it problematic to migrate between networks that need different parameters (vnlink/vepa for example).

[libvirt] [v3 00/14] USB improvements and new redirdev
by Marc-André Lureau 03 Sep '11

03 Sep '11

Hei, Here we go with the third version of this patch series that leads to support for various USB controllers, USB hubs, and USB redirection devices. Major change since v2 is the creation of a new element 'redirdev' instead of reusing the existing 'hostdev'. Marc-André Lureau (14): Add various USB devices QEMU_CAPS Split virDomainControllerModel to virDomainControllerModelSCSI Add USB controller models Add a new controller type 'usb' with optionnal 'model' USB controller can have a PCI address child element USB devices gain a new USB address child element Add USB companion controllers support Add USB hub device Modify USB port to be defined as a port path qemu: don't reserve slot 1 if a PIIX3 USB controller is defined there qemu: Don't append 0 at usb id, so that it is compatible with legacy -usb Add a usb1 & usb2 qemuxml2argv test Add "redirdev" redirection device Learn to use spicevmc as a redirection type for usb-redir docs/formatdomain.html.in | 105 +++++- docs/schemas/domain.rng | 100 ++++- src/conf/domain_audit.c | 65 +++ src/conf/domain_audit.h | 5 + src/conf/domain_conf.c | 443 +++++++++++++++++++- src/conf/domain_conf.h | 104 +++++- src/esx/esx_driver.c | 8 +- src/libvirt_private.syms | 11 +- src/qemu/qemu_capabilities.c | 28 ++ src/qemu/qemu_capabilities.h | 9 + src/qemu/qemu_command.c | 342 ++++++++++++++- src/qemu/qemu_command.h | 14 +- src/qemu/qemu_driver.c | 7 + src/qemu/qemu_hotplug.c | 55 +++- src/qemu/qemu_hotplug.h | 3 + src/vmx/vmx.c | 32 +- tests/qemuhelptest.c | 17 +- .../qemuxml2argv-input-usbmouse-addr.args | 1 + .../qemuxml2argv-input-usbmouse-addr.xml | 27 ++ .../qemuxml2argv-usb-controller.args | 1 + .../qemuxml2argv-usb-controller.xml | 16 + tests/qemuxml2argvdata/qemuxml2argv-usb-hub.args | 1 + tests/qemuxml2argvdata/qemuxml2argv-usb-hub.xml | 19 + .../qemuxml2argv-usb-ich9-companion.args | 6 + .../qemuxml2argv-usb-ich9-companion.xml | 30 ++ .../qemuxml2argv-usb-ich9-ehci-addr.args | 1 + .../qemuxml2argv-usb-ich9-ehci-addr.xml | 18 + .../qemuxml2argv-usb-piix3-controller.args | 1 + .../qemuxml2argv-usb-piix3-controller.xml | 16 + tests/qemuxml2argvdata/qemuxml2argv-usb-ports.args | 1 + tests/qemuxml2argvdata/qemuxml2argv-usb-ports.xml | 31 ++ tests/qemuxml2argvdata/qemuxml2argv-usb-redir.args | 10 + tests/qemuxml2argvdata/qemuxml2argv-usb-redir.xml | 40 ++ tests/qemuxml2argvdata/qemuxml2argv-usb1-usb2.args | 15 + tests/qemuxml2argvdata/qemuxml2argv-usb1-usb2.xml | 74 ++++ tests/qemuxml2argvtest.c | 30 ++ tests/qemuxml2xmltest.c | 2 + tests/xml2vmxtest.c | 2 +- 38 files changed, 1598 insertions(+), 92 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-input-usbmouse-addr.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-input-usbmouse-addr.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-controller.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-controller.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-hub.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-hub.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ich9-companion.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ich9-companion.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ich9-ehci-addr.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ich9-ehci-addr.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-piix3-controller.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-piix3-controller.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ports.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ports.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-redir.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-redir.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb1-usb2.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb1-usb2.xml -- 1.7.6

[libvirt] [PATCH 0/8] Report disk latency info
by Osier Yang 02 Sep '11

02 Sep '11

This patch series introduces a new API to report the disk latency related information, which is supported by upstream QEMU just a few days ago (commit c488c7f649, Thu Aug 25). Per previous dicussion on the ABI compatiblity, and API design principle, the new API is defined with style: typedef struct _virDomainBlockStatsFlags virDomainBlockStatsFlagsStruct; typedef virDomainBlockStatsFlagsStruct *virDomainBlockStatsFlagsPtr; struct _virDomainBlockStatsFlags { char field[VIR_DOMAIN_BLOCK_STATS_FIELD_LENGTH]; long long value; }; int virDomainBlockStatsFlags (virDomainPtr dom, const char *path, virDomainBlockStatsFlagsPtr params, int *nparams, unsigned int flags) Other points: 1) With the new API, output of virsh command "domblkstat" is different, this might affect the existed scripts. But considering we are even introducing new feilds, so this can be fine? 2) qemuMonitorJSONGetBlockStatsInfo set "*errs = 0" before, it will cause "domblkstat" always print things like "vda errs 0". However, QEMU doesn't support this field. Fixed it in these patches (*errs = -1). And new API qemuDomainBlockStatsFlags won't even set a field for "errs". 3) Is it deserved to update gendispatch.pl to generate remote codes for functions take argument like "virNodeCPUStatsPtr params", "virNodeMemoryStatsPtr params"? All of these argument points to structs has same structure. Perhaps we can define an alias for these structs and generate the remote codes just like for "virTypedParameterPtr params". [PATCH 1/8] latency: Define new public API and structure [PATCH 2/8] latency: Define the internal driver callback [PATCH 3/8] latency: Implemente the public API [PATCH 4/8] latency: Wire up the remote protocol [PATCH 5/8] latency: Update monitor functions for new latency fields [PATCH 6/8] latency: Implemente internal API for qemu driver [PATCH 7/8] latency: Expose the new API for Python binding [PATCH 8/8] latency: Update cmdBlkStats to use new API Regards, Osier

[libvirt] [PATCH 0/3 v4] Add filesystem pool formatting
by Osier Yang 02 Sep '11

02 Sep '11

The following patches add the ability to format filesystem pools when the appropriate flags are passed to pool build. This patch set introduces two new flags: VIR_STORAGE_POOL_BUILD_NO_OVERWRITE causes the build to probe for an existing pool of the requested type. The build operation formats the filesystem if it does not find an existing filesystem of that type. VIR_STORAGE_POOL_BUILD_OVERWRITE causes the build to format unconditionally. This patch set is mainly based on v3 by Dave Allan. http://www.redhat.com/archives/libvir-list/2010-June/msg00042.html [PATCH 1/3] storage: Add mkfs and libblkid to build system [PATCH 2/3] storage: Add fs pool formatting [PATCH 3/3] storage: Add virsh support for fs pool formating Regards, Osier

[libvirt] Preparing for next release 0.9.5
by Daniel Veillard 02 Sep '11

02 Sep '11

To try to keep good habits and stay predictable I would suggest to enter development freeze this week-end to plan an upstream release on Friday 2nd Sep or early the following week. I may also switch the libvirt.org server to a new box at that time, but it's not really urgent, th new box would be less powerful, but with overall better network reliability.

Hi, qemu supports specification of NUMA topology on command line using -numa option. -numa node[,mem=size][,cpus=cpu[-cpu]][,nodeid=node] I see that there is no way to specify such NUMA topology in libvirt XML. Are there plans to add support for NUMA topology specification ? Is anybody already working on this ? If not I would like to add this support for libvirt. Currently the topology specification available in libvirt ( <topology sockets='1' cores='2' threads='1'/>) translates to "-smp sockets=1,cores=2,threads=1" option of qemu. There is not equivalent in libvirt that could generate -numa command line option of qemu. How about something like this ? (OPTION 1) <cpu> ... <numa nodeid='node' cpus='cpu[-cpu]' mem='size'> ... </cpu> And we could specify multiple such lines, one for each node. -numa and -smp options in qemu do not work all that well since they are parsed independent of each other and one could specify a cpu set with -numa option that is incompatible with sockets,cores and threads specified on -smp option. This should be fixed in qemu, but given that such a problem has been observed, should libvirt tie the specification of numa and smp (sockets,threads,cores) together so that one is forced to specify only valid combinations of nodes and cpus in libvirt ? May be something like this: (OPTION 2) <cpu> ... <topology sockets='1' cores='2' threads='1' nodeid='0' cpus='0-1' mem='size'> <topology sockets='1' cores='2' threads='1' nodeid='1' cpus='2-3' mem='size'> ... </cpu This should result in a 2 node system with each node having 1 socket with 2 cores. Comments, suggestions ? Regards, Bharata. -- http://bharata.sulekha.com/blog/posts.htm, http://raobharata.wordpress.com/

[libvirt] [PATCH] start: allow discarding managed save
by Eric Blake 02 Sep '11

02 Sep '11

There have been several instances of people having problems with a broken managed save file causing 'virsh start' to fail, and not being aware that they could use 'virsh managedsave-remove dom' to fix things. Making it possible to do this as part of starting a domain makes the same functionality easier to find, and one less API call. * include/libvirt/libvirt.h.in (VIR_DOMAIN_START_FORCE_BOOT): New flag. * src/libvirt.c (virDomainCreateWithFlags): Document it. * src/qemu/qemu_driver.c (qemuDomainObjStart): Alter signature.

[libvirt] [PATCH] lxc: do not require 'ifconfig' or 'ipconfig' in container
by Scott Moser 02 Sep '11

02 Sep '11

Currently, the lxc implementation invokes 'ip' and 'ifconfig' commands inside a container using 'virRun'. That has the side effect of requiring those commands to be present and to function in a manner consistent with the usage. Some small roots (such as ttylinux) may not have 'ip' or 'ifconfig'. This patch replaces the use of these commands with usage of netdevice. The result is that lxc containers do not have to implement those commands, and lxc in libvirt is only dependent on the netdevice interface. I've tested this patch locally against the ubuntu libvirt version enough to verify its generally sane. I attempted to build upstream today, but failed with: /usr/bin/ld: ../src/.libs/libvirt_driver_qemu.a(libvirt_driver_qemu_la-qemu_domain.o): undefined reference to symbol 'xmlXPathRegisterNs@@LIBXML2_2.4.30 Thats probably a local issue only, but I wanted to get this patch up and see what others thought of it.

[libvirt] [RFC] Create ptmx as a device
by Serge Hallyn 02 Sep '11

02 Sep '11

Hi, I'm seeing an issue with udev and libvirt-lxc. Libvirt-lxc creates /dev/ptmx as a symlink to /dev/pts/ptmx. When udev starts up, it checks the device type, sees ptmx is 'not right', and replaces it with a 'proper' ptmx. In lxc, /dev/ptmx is bind-mounted from /dev/pts/ptmx instead of being symlinked, so udev sees the right device type and leaves it alone. A patch like the following seems to work for me. Would there be any objections to this? >From 4c5035de52de7e06a0de9c5d0bab8c87a806cba7 Mon Sep 17 00:00:00 2001 From: Ubuntu <ubuntu(a)domU-12-31-39-14-F0-B3.compute-1.internal> Date: Wed, 31 Aug 2011 18:15:54 +0000 Subject: [PATCH 1/1] make ptmx a bind mount rather than symlink udev on some systems checks the device type of /dev/ptmx, and replaces it if not as expected.

[libvirt] [PATCH] Increase size of buffer for xend response

[libvirt] Problems with "attach-interface" command of libvirt
by Tao Siheng 01 Sep '11

01 Sep '11

Dear libvirt-developer: I'm a student of computer science and technology in China. I encountered a problem when I want to attach a bridge to an existed Virtual Machine. I used the command "attach-interface domain_id bridge br0 --target tap0". "br0" was created by brctl and "tap0" was created by tunctl.Here is the error information: error: Failed to attach interface error: internal error unable to send TAP file handle: No file descriptor supplied via SCM_RIGHTS. I know there are some bugs in the earlier version of libvirt. So I upgraded the ubuntu kernel to 2.6.38.8 and added the module "macvtap" by the using the command "sudo modprobe macvtap". I have installed libvirt0.8.8, QEMU 0.8.8 and QEMU 0.12.3.Although I did all the above, the problem is still not solved. I need your help sincerely. Tao Siheng 2011.9.1

[libvirt] [PATCH 0/6] Support online block resizing
by Osier Yang 01 Sep '11

01 Sep '11

Upstream QEMU introduced online block resizing to resize the block device when domain is running since commit 6d4a2b3a4795. It simply reuses existing "bdrv_truncate" method which is used by "qemu-img" to resize the images. This means it supports to resize all the format that "qemu-img resize" supports. E.g. qcow2, raw, qed, qcow, etc. (NB, it doesn't support to shrink size of qcow2 image, and QEMU reports "An undefined error has ocurred" in this case). For block device of virtio bus, the guest can update the device size automatically, needs kernel support, since kernel-2.6.32-117: http://patchwork.usersys.redhat.com/patch/33040/ For block device of SCSI bus, one needs to execute command like below in the guest (linux) to update the size: % echo > /sys/class/scsi_device/0:0:0:0/device/rescan For block device of IDE bus, seems there is no way to let guest update the size after resizing. The new API is defined as: int virDomainBlockResize (virDomainPtr dom, const char *device, unsigned long long size, unsigned int flags) * @device is the name of block device, E.g. vda, vdb. * Units for @size is KB. [PATCH 1/6] block_resize: Define the new API [PATCH 2/6] block_resize: Implemente the public API [PATCH 3/6] block_resize: Wire up the remote protocol [PATCH 4/6] block_resize: Implemente the qemu monitor functions [PATCH 5/6] block_resize: Implemente the internal API for qemu [PATCH 6/6] block_resize: Expose the new API in virsh Regards, Osier

[libvirt] [v2 00/13] various USB support improvements
by Marc-André Lureau 01 Sep '11

01 Sep '11

Hola, This is the second version of the patch set which should address most of the comments I recieved. It should be good enough to let virt-manager & co support USB2 & usb-redirection. Some of the auto-assign of USB addresses etc.. are leftover for future improvements. It should not introduce regressions. Marc-André Lureau (13): Add various USB devices QEMU_CAPS Split virDomainControllerModel to virDomainControllerModelSCSI Add USB controller models Add a new controller type 'usb' with optionnal 'model' USB controller can have a PCI address child element USB devices gain a new USB address child element Add USB companion controllers support Add USB hub device Modify USB port to be defined as a port path qemu: don't reserve slot 1 if a PIIX3 USB controller is defined there qemu: Don't append 0 at usb id, so that it is compatible with legacy -usb Add a usb1 & usb2 qemuxml2argv test Add usb-redir device docs/formatdomain.html.in | 81 ++++- docs/schemas/domain.rng | 122 +++++-- src/conf/domain_conf.c | 369 +++++++++++++++++++- src/conf/domain_conf.h | 82 ++++- src/esx/esx_driver.c | 8 +- src/libvirt_private.syms | 8 +- src/qemu/qemu_capabilities.c | 28 ++ src/qemu/qemu_capabilities.h | 9 + src/qemu/qemu_cgroup.c | 3 +- src/qemu/qemu_command.c | 284 ++++++++++++++-- src/qemu/qemu_command.h | 10 +- src/qemu/qemu_hostdev.c | 2 + src/qemu/qemu_hotplug.c | 66 ++++- src/qemu/qemu_hotplug.h | 3 + src/security/security_dac.c | 6 + src/security/security_selinux.c | 6 + src/vmx/vmx.c | 32 +- tests/qemuhelptest.c | 17 +- .../qemuxml2argv-input-usbmouse-addr.args | 1 + .../qemuxml2argv-input-usbmouse-addr.xml | 27 ++ .../qemuxml2argv-usb-controller.args | 1 + .../qemuxml2argv-usb-controller.xml | 16 + tests/qemuxml2argvdata/qemuxml2argv-usb-hub.args | 1 + tests/qemuxml2argvdata/qemuxml2argv-usb-hub.xml | 19 + .../qemuxml2argv-usb-ich9-companion.args | 6 + .../qemuxml2argv-usb-ich9-companion.xml | 30 ++ .../qemuxml2argv-usb-ich9-ehci-addr.args | 1 + .../qemuxml2argv-usb-ich9-ehci-addr.xml | 18 + .../qemuxml2argv-usb-piix3-controller.args | 1 + .../qemuxml2argv-usb-piix3-controller.xml | 16 + tests/qemuxml2argvdata/qemuxml2argv-usb-ports.args | 1 + tests/qemuxml2argvdata/qemuxml2argv-usb-ports.xml | 31 ++ tests/qemuxml2argvdata/qemuxml2argv-usb-redir.args | 8 + tests/qemuxml2argvdata/qemuxml2argv-usb-redir.xml | 33 ++ tests/qemuxml2argvdata/qemuxml2argv-usb1-usb2.args | 15 + tests/qemuxml2argvdata/qemuxml2argv-usb1-usb2.xml | 74 ++++ tests/qemuxml2argvtest.c | 29 ++ tests/xml2vmxtest.c | 2 +- 38 files changed, 1350 insertions(+), 116 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-input-usbmouse-addr.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-input-usbmouse-addr.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-controller.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-controller.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-hub.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-hub.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ich9-companion.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ich9-companion.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ich9-ehci-addr.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ich9-ehci-addr.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-piix3-controller.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-piix3-controller.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ports.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-ports.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-redir.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-redir.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb1-usb2.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb1-usb2.xml -- 1.7.6

[libvirt] [PATCH] Fix tracking of RPC messages wrt streams
by Daniel P. Berrange 01 Sep '11

From: "Daniel P. Berrange" <berrange(a)redhat.com> Commit 2c85644b0b51fbe5b6244e6773531af29933a727 attempted to fix a problem with tracking RPC messages from streams by doing - if (msg->header.type == VIR_NET_REPLY) { + if (msg->header.type == VIR_NET_REPLY || + (msg->header.type == VIR_NET_STREAM && + msg->header.status != VIR_NET_CONTINUE)) { client->nrequests--; In other words any stream packet, with status NET_OK or NET_ERROR would cause nrequests to be decremented. This is great if the packet from from a synchronous virStreamFinish or virStreamAbort API call, but wildly wrong if from a server initiated abort. The latter resulted in 'nrequests' being decremented below zero. This then causes all I/O for that client to be stopped. Instead of trying to infer whether we need to decrement the nrequests field, from the message type/status, introduce an explicit 'bool tracked' field to mark whether the virNetMessagePtr object is subject to tracking. Also add a virNetMessageClear function to allow a message contents to be cleared out, without adversely impacting the 'tracked' field as a naive memset() would do * src/rpc/virnetmessage.c, src/rpc/virnetmessage.h: Add a 'bool tracked' field and virNetMessageClear() API * daemon/remote.c, daemon/stream.c, src/rpc/virnetclientprogram.c, src/rpc/virnetclientstream.c, src/rpc/virnetserverclient.c, src/rpc/virnetserverprogram.c: Switch over to use virNetMessageClear() and pass in the 'bool tracked' value when creating messages. --- daemon/remote.c | 2 +- daemon/stream.c | 10 +++++----- src/rpc/virnetclientprogram.c | 2 +- src/rpc/virnetclientstream.c | 4 ++-- src/rpc/virnetmessage.c | 14 ++++++++++++-- src/rpc/virnetmessage.h | 6 +++++- src/rpc/virnetserverclient.c | 12 +++++------- src/rpc/virnetserverprogram.c | 2 +- 8 files changed, 32 insertions(+), 20 deletions(-) diff --git a/daemon/remote.c b/daemon/remote.c index 34c6364..d5ead81 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -2495,7 +2495,7 @@ remoteDispatchDomainEventSend(virNetServerClientPtr client, { virNetMessagePtr msg;

[libvirt] Python stream callback removal
by Dave Allan 31 Aug '11

31 Aug '11

I'm trying to write an example serial console implementation in python (attached), but I'm having some trouble getting stream events to do what I want. The console itself works fine as long as the domain stays up, but as soon as the domain shuts down the python script goes into a tight loop repeatedly calling the stream event callback. Debugging indicates that the stream event callback is being requested to be removed, but it never actually is removed which makes me think I am not properly releasing some resource, but I was under the impression that an error on a stream resulting in the stream aborting was supposed to free all the resources for me. Is that not correct? Thanks for any help anybody can provide, Dave

[libvirt] [PATCH] Don't leak memory if a cgroup is mounted multiple times

Yes, I agree it would be simplest to pick the right mechanism, depending on the type of throttling the user wants.

Am I correct or are we > suggesting that the Qemu throttling approach should always be used for Qemu > domains? QEMU I/O throttling does not provide a proportional share mechanism. So you cannot assign weights to VMs and let them receive a fraction of the available disk time. That is only supported by cgroups blkio-controller because it requires a global view which QEMU does not have. So I think the two are complementary: If proportional share should be used on a host block device, use cgroups blkio-controller. Otherwise use QEMU I/O throttling. Stefan

[libvirt] [PATCH] snapshot: forbid snapshot on autodestroy domain

There is no reason to forbid pausing an autodestroy domain (not to mention that 'virsh start --paused --autodestroy' succeeds in creating a paused autodestroy domain). Meanwhile, qemu was failing to enforce the API documentation that autodestroy domains cannot be saved.

[libvirt] [PATCH] build: simplify use of verify
by Eric Blake 30 Aug '11

30 Aug '11

Back in 2008 when this line of util.h was written, gnulib's verify module didn't allow the use of multiple verify() in one file in combination with our choice of gcc -W options. But that has since been fixed in gnulib, and newer gnulib even maps verify() to the C1x feature of _Static_assert, which gives even nicer diagnostics with a new enough compiler, so we might as well go with the simpler verify(). * src/util/util.h (VIR_ENUM_IMPL): Use simpler verify, now that gnulib module is smarter. --- As pointed out here: https://www.redhat.com/archives/libvir-list/2011-August/msg01348.html src/util/util.h | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/util/util.h b/src/util/util.h index 6e6265f..908ba7b 100644 --- a/src/util/util.h +++ b/src/util/util.h @@ -202,7 +202,7 @@ const char *virEnumToString(const char *const*types, # define VIR_ENUM_IMPL(name, lastVal, ...) \ static const char *const name ## TypeList[] = { __VA_ARGS__ }; \ - extern int (* name ## Verify (void)) [verify_true (ARRAY_CARDINALITY(name ## TypeList) == lastVal)]; \ + verify(ARRAY_CARDINALITY(name ## TypeList) == lastVal); \ const char *name ## TypeToString(int type) { \ return virEnumToString(name ## TypeList, \ ARRAY_CARDINALITY(name ## TypeList), \ -- 1.7.4.4

[libvirt] [PATCH v2 0/5] Virtual interface link state modification
by Peter Krempa 30 Aug '11

30 Aug '11

This patchset adds the ability for libvirt users to control interface link state of the virtual network devices provided by hypervisors. Modification of the link state is accomplished by adding a new XML element <link state"up"> or "down" to the domain XML. The corresponding network interface is thereafter initialised with the desired state. Live modification of the link state is achieved by calling virDomainUpdateDeviceFlags containing a modified interface configuration. Yet, users may modify only link state of an interface. This feature allows propagation of network topology changes to guests, testing scenarios in complex virtual networks, etc ... Future upgrade: - add support for VirtualBox Modifications to v1: - use virUpdateDeviceFlags instead of dedicated API - incorporate helpful comments by Eric Blake https://bugzilla.redhat.com/show_bug.cgi?id=643373 Peter Krempa (5): link-state: util: Add equality comparision functions for structures link-state: conf: Add element to XML for controling link state link-state: qemu: Add monitor handling for link state modification link-state: qemu: Add net intf modification to virUpdateDeviceFlags link-state: virsh: Add wrapper commands for changing link state docs/formatdomain.html.in | 21 +++ docs/schemas/domain.rng | 11 ++ src/conf/domain_conf.c | 24 ++++ src/conf/domain_conf.h | 11 ++ src/qemu/qemu_driver.c | 24 ++++ src/qemu/qemu_hotplug.c | 176 ++++++++++++++++++++++++++ src/qemu/qemu_hotplug.h | 8 ++ src/qemu/qemu_monitor.c | 19 +++ src/qemu/qemu_monitor.h | 4 + src/qemu/qemu_monitor_json.c | 23 ++++ src/qemu/qemu_monitor_json.h | 4 + src/qemu/qemu_monitor_text.c | 46 +++++++ src/qemu/qemu_monitor_text.h | 4 + src/qemu/qemu_process.c | 47 +++++++- src/util/network.c | 62 +++++++++ src/util/network.h | 5 + tools/virsh.c | 286 ++++++++++++++++++++++++++++++++++++++++++ tools/virsh.pod | 11 ++ 18 files changed, 785 insertions(+), 1 deletions(-) -- 1.7.3.4

But currently i met some design questions, and don't make sure if we should extend blkiotune to support block I/O throttling or introduce one new libvirt command "blkiothrottle" to cover it or not. If you have some better idea, pls don't hesitate to drop your comments. If one new libvirt command "blkiothrottle" is introduced, I plan to design its usage syntax as below: virsh # help blkiothrottle NAME blkiothrottle - Set or display a block disk I/O throttle setting. SYNOPSIS blkiothrottle <domain> <device> [--bps <number>] [--bps_rd <number>] [--bps_wr <number>] [--iops <number>] [--iops_rd <number>] [--iops_wr <number>] DESCRIPTION Set or display a block disk I/O throttle setting. OPTIONS [--domain] <string> domain name, id or uuid [--device] <string> block device --bps <number> total throughput limits in bytes/s --bps_rd <number> read throughput limits in bytes/s --bps_wr <number> write throughput limits in bytes/s --iops <number> total operation limits in numbers/s --iops_rd <number> read operation limits in numbers/s --iops_wr <number> write operation limits in numbers/s virsh # 2.) If blkiotune command is extended to enable block I/O throttling function. virsh # help blkiotune NAME blkiotune - Get or set blkio parameters SYNOPSIS blkiotune <domain> [--weight <number>] [--config] [--live] [--current] [--bps <number>] [--bps_rd <number>] [--bps_wr <number>] [--iops <number>] [--iops_rd <number>] [--iops_wr <number>] DESCRIPTION Get or set the current blkio parameters for a guest domain. To get the blkio parameters use following command: virsh # blkiotune <domain> OPTIONS [--domain] <string> domain name, id or uuid --weight <number> IO Weight in range [100, 1000] --config affect next boot --live affect running domain --current affect current domain Welcome to your suggestions or comments about how to choose it. thanks. -- Regards, Zhi Yong Wu

[libvirt] [v2 0/4] python-virtinst USB improvements
by Marc-André Lureau 29 Aug '11

29 Aug '11

Hi, Here are a few patches that go with the libvirt series to improve USB support. It adds --controller and --usbredir, as well as providing some new API for virt-manager. The last patch default USB controller to ich9/usb2 on Windows 7 guest. More OS probably support it, since it's been around since early 2007. v2 adds support for USB redirection over Spice.

[libvirt] [PATCH 0/3] Enable automatic kill of running guests
by Daniel P. Berrange 26 Aug '11

26 Aug '11

I am building an application which uses KVM to run specific tasks, rather than as a general purpose guest OS. I want to ensure that when the app exits, the guest goes away too. To enable this, this series introduces the concept of 'autokill', whereby a guest is forcably destroyed when the virConnectPtr that launched it closes. This also lets us fix a long standing problem with migration leaving an unkillable guest

[libvirt] [PATCH] rpc: Don't close connection if program is unknown
by Jiri Denemark 26 Aug '11

26 Aug '11

In case we add a new program in the future (we did that in the past and we are going to do it again soon) current daemon will behave badly with new client that wants to use the new program. Before the RPC rewrite we used to just sent an error reply to any request with unknown program. With the RPC rewrite in 0.9.3 the daemon just closes the connection through which such request was sent.

[libvirt] [PATCH 0/3 TCK] Some tests for snapshot management
by Daniel P. Berrange 26 Aug '11

26 Aug '11

All these tests fail with current GIT, but are intended to work with Eric's snapshot series applied. The first test in this list, however, does not pass. Eric's current tree forbids calling 'Destroy' on a transient guest which has snapshots present. IMHO this is wrong, because the guest may itself exit at any time, which leaves us in the same state as is 'Destroy' had been called wrt snapshots. IMHO, we should be allowed to call 'virDomainDestroy' on a transient guest with snapshots, and then later 'virDomainCreateXML' to re-create the guest and still have access to the snapshots In other words, just because a transient guest is not currently present, does not mean we should forget about its snapshots as a management app can re-create it again at any time. Forbidding virDomainUndefine with snapshots is more reasonable, but I think its still possible to argue that it should be allowed and that a later virDomainDefine with the same name+uuid should resurrect any previous snapshots.

[libvirt] [PATCH 1/2] Fix keymap used to talk with QEMU
by Daniel P. Berrange 26 Aug '11

26 Aug '11

From: "Daniel P. Berrange" <berrange(a)redhat.com> The QEMU 'sendkey' command expects keys to be encoded in the same way as the RFB extended keycode set. Specfically it wants extended keys to have the high bit of the first byte set, while the Linux XT KBD driver codeset uses the low bit of the second byte. To deal with this we introduce a new keymap 'RFB' and use that in the QEMU driver * include/libvirt/libvirt.h.in: Add VIR_KEYCODE_SET_RFB * src/qemu/qemu_driver.c: Use RFB keycode set instead of XT KBD * src/util/virkeycode-mapgen.py: Auto-generate the RFB keycode set from the XT KBD set * src/util/virkeycode.c: Add RFB keycode entry to table.
