[libvirt] [PATCH v2] deprecate fclose() and introduce VIR_{FORCE_}FCLOSE()
by Stefan Berger 15 Nov '10

15 Nov '10

V2: - following Eric's suggestion, deprecating fdclose(), introducing VIR_FDCLOSE() - following some other nits that Eric pointed out - replaced some more fclose () I previously had missed (last 2 files in patch) Similarly to deprecating close(), I am now deprecating fclose() and introduce VIR_FORCE_FCLOSE() and VIR_FCLOSE(). Also, fdopen() is replaced with VIR_FDOPEN(). Most of the files are opened in read-only mode, so usage of VIR_FORCE_CLOSE() seemed appropriate. Others that are opened in write mode already had the fclose() < 0 check and I converted those to VIR_FCLOSE() < 0. I did not find occurrences of possible double-closed files on the way.

[libvirt] [PATCH] interface.rng: Make miimon and arpmon optional for bond interfaces
by Laine Stump 15 Nov '10

This has been optional in netcf for awhile, but the change hadn't been propogated to the libvirt copy of the RNG. --- I noticed this was out of date while updating the netcf RNG with the new regex for ipv4-address. Note that, although the diff is long, it's just adding <optional>...</optional> around the section, and re-indenting. Everything in the middle is only whitespace changes. docs/schemas/interface.rng | 77 +++++++++++++++++++++++--------------------- 1 files changed, 40 insertions(+), 37 deletions(-) diff --git a/docs/schemas/interface.rng b/docs/schemas/interface.rng index 75893b5..4dd1bb4 100644 --- a/docs/schemas/interface.rng +++ b/docs/schemas/interface.rng @@ -177,43 +177,46 @@ xmit_hash_policy (since 2.6.3/3.2.2) --> - <choice> - <element name="miimon"> -  - <attribute name="freq"><ref name="uint"/></attribute> - <optional> - <attribute name="downdelay"><ref name="uint"/></attribute> - </optional> - <optional> - <attribute name="updelay"><ref name="uint"/></attribute> - </optional> - <optional> -  - <attribute name="carrier"> - <choice> -  - <value>ioctl</value> -  - <value>netif</value> - </choice> - </attribute> - </optional> - </element> - <element name="arpmon"> - <attribute name="interval"><ref name="uint"/></attribute> - <attribute name="target"><ref name="ipv4-addr"/></attribute> - <optional> - <attribute name="validate"> - <choice> - <value>none</value> - <value>active</value> - <value>backup</value> - <value>all</value> - </choice> - </attribute> - </optional> - </element> - </choice> + <optional> + <choice> + <element name="miimon"> +  + <attribute name="freq"><ref name="uint"/></attribute> + <optional> + <attribute name="downdelay"><ref name="uint"/></attribute> + </optional> + <optional> + <attribute name="updelay"><ref name="uint"/></attribute> + </optional> + <optional> +  + <attribute name="carrier"> + <choice> +  + <value>ioctl</value> +  + <value>netif</value> + </choice> + </attribute> + </optional> + </element> + <element name="arpmon"> + <attribute name="interval"><ref name="uint"/></attribute> + <attribute name="target"><ref name="ipv4-addr"/></attribute> + <optional> + <attribute name="validate"> + <choice> + <value>none</value> + <value>active</value> + <value>backup</value> + <value>all</value> + </choice> + </attribute> + </optional> + </element> + </choice> + </optional> + <oneOrMore>  <ref name="bare-ethernet-interface"/> -- 1.7.2.3

[libvirt] [PATCH] [TCK] Convert scripts to also run with dash
by Stefan Berger 15 Nov '10

15 Nov '10

I am converting the shell-scripted tap tests to also run using the dash shell, fixing some other problems on the way as well. Two of the tests' data files contained '\\1' in an sed command. This created char(1) with the dash, '\1' with the bash. I found it easier to replace the sed command with a different one than figuring out how to solve this escape problem so it works for both shells.

[libvirt] [PATCH v2] macvtap: convert send / recv function to use libnl

-V2: - adapting patch due to changes in the same file by another patch In a second step I am converting the netlink send/receive functions to use libnl. I tested this with 802.1Qbg profiles and my test server and did not see a regression.

[libvirt] [PATCH] RFC: Remove all object hashtable caches from virConnectPtr
by Daniel P. Berrange 15 Nov '10

15 Nov '10

The virConnectPtr struct will cache instances of all other objects. APIs like virDomainLookupByUUID will return a cached object, so if you do virDomainLookupByUUID twice in a row, you'll get the same exact virDomainPtr instance. This does not have any performance benefit, since the actual logic in virDomainLookupByUUID (and other APIs returning virDomainPtr, etc instances) is not short-circuited. All it does is to ensure there is only one single virDomainPtr in existance for any given UUID. The caching has a number of downsides though, all relating to stale data. If APIs aren't careful to always overwrite the 'id' field in virDomainPtr it may become out of data. Likewise for the name field, if a guest is renamed, or if a guest is deleted, and then a new one created with the same UUID but different name. This has been an ongoing, endless source of bugs for all applications using libvirt from languages with garbage collection, causing them to get virDomainPtr instances from long ago with stale data. The caching is also a waste of memory resources, since both applications, and language bindings often maintain their own hashtable caches of object instances. This patch removes all the hash table caching, so all APIs return brand new virDomainPtr (etc) object instances. Other options include - Explicitly overrite the 'name' field in the cached objects every time they are looked up, to ensure fully up2date objects - Add a flag to virConnectOpen to allow apps to turn off caching themselves. * src/datatypes.h: Delete all hash tables. * src/datatypes.c: Remove all object caching code --- src/datatypes.c | 657 +++++++++++++------------------------------------------ src/datatypes.h | 10 - 2 files changed, 149 insertions(+), 518 deletions(-) diff --git a/src/datatypes.c b/src/datatypes.c index 46009ae..66dbc99 100644 --- a/src/datatypes.c +++ b/src/datatypes.c @@ -41,120 +41,6 @@ * * ************************************************************************/ -/** - * virDomainFreeName: - * @domain: a domain object - * - * Destroy the domain object, this is just used by the domain hash callback. - * - * Returns 0 in case of success and -1 in case of failure. - */ -static int -virDomainFreeName(virDomainPtr domain, const char *name ATTRIBUTE_UNUSED) -{ - return (virUnrefDomain(domain));

[libvirt] [RFC] Proposed API to support block device streaming
by Adam Litke 15 Nov '10

15 Nov '10

I've been working with Anthony Liguori and Stefan Hajnoczi to enable data streaming to copy-on-read disk images in qemu. This work is working its way through peer review and I expect it to be upstream soon as part of the support for the new QED disk image format. I would like to enable these commands in libvirt in order to support at least two compelling use cases: 1) Rapid deployment of domains: Creating a new domain from a central repository of images can be time consuming since a local copy of the image must be made before the domain can be started. With copy-on-read and streaming, up-front copy time is eliminated and the domain can be started immediately. Streaming can run while the domain runs to fully populate the disk image. 2) Post-copy live block migration: A qemu-nbd server is started on the source host and serves the domain's block device to the destination host. A QED image is created on the destination host with backing to the nbd server. The domain is migrated as normal. When migration completes, a stream command is executed to fully populate the destination QED image. After streaming completes, the qemu-nbd server can be shut down and the domain (including local storage) is fully independent of the source host. Qemu will support two streaming modes: full device and single sector. Full device streaming is the easiest to use because one command will cause the whole device to be streamed as fast as possible. Single sector mode can be used if one wants to throttle streaming to reduce I/O pressure. In this mode, the user issues individual commands to stream single sectors. To enable this support in libvirt, I propose the following API... virDomainStreamDisk() initiates either a full device stream or a single sector stream (depending on virDomainStreamDiskFlags). For a full device stream, it returns either 0 or -1. For a single sector stream, it returns an offset that can be used to continue streaming with a subsequent call to virDomainStreamDisk(). virDomainStreamDiskInfo() returns the status of a currently-running full device stream (the device name, current streaming position, and total size). Comments on this design would be greatly appreciated.

[libvirt] Ask for help about libvirt error: this function is not supported by the connection driver..
by Feng Dan Liu 15 Nov '10

15 Nov '10

Hi, I'm a libvirt user, I encountered a problem when I use the libvirt java bindings, could you please help me take a look？ Thanks in advance! Any suggestions from anyone of you will be very appreciated. Here is my scenario: Remote access machine A is a RHEL 5.4 workstation with the command "virsh version" results: Compiled against library: libvir 0.8.1 Using library: libvir 0.8.1 Using API: Xen 3.0.1 Running hypervisor: Xen 3.1.0 Hypervisor machine B is a Fedora Core 14 Linux workstation with the command "virsh version" results: Compiled against library: libvir 0.8.3 Using library: libvir 0.8.3 Using API: QEMU 0.8.3 Running hypervisor: QEMU 0.13.0 I finished the code using libvirt java bindings and run it on machine A, try to remote connect to the hypervisor on machine B. It can be connected succussfully, but when the code calls the function of conn.listDefinedStoragePools() or conn.listStoragePools, the libvirt on machine B will get the errors below: 04:19:10.467: error : phypStorageOpen:3884 : invalid argument in phypStorageOpen: unsupported flags (0x1) 04:19:11.354: warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit status '1', qemu probably failed 04:19:12.128: error : virLibConnError:448 : this function is not supported by the connection driver: virConnectNumOfStoragePools With the errors above, my code can't run the functions of conn.listDefinedStoragePools() or conn.listStoragePools successfully. Could you please give me some suggestions? By the way, I try to use the libvirt java bindings 0.3.2 and 0.4.6, both of them have this problem.

Re: [libvirt] Is there an API for clone?
by Alex Jia 14 Nov '10

14 Nov '10

Hi lancer, As Osier said, libvirt hasn't a independent API for cloning an existing guest, instead of using virStorageVolGetXMLDesc API to get a guest volume xml description and then calling virStorageVolCreateXMLFrom API to clone a new volume. For python-virtinst component, you may use virt-clone to implement this, for libvirt component, you may directly use python binding API or virsh tool 'vol-clone' to implement it. I hope it's helpful for you. - Alex ----- Original Message ----- From: "黄亮" <lancerhuang(a)163.com> To: "libvir-list" <libvir-list(a)redhat.com> Sent: Wednesday, November 10, 2010 9:30:28 AM GMT +08:00 Beijing / Chongqing / Hong Kong / Urumqi Subject: [libvirt] Is there an API for clone? Hi, guys I know there is a command "virt-clone", but I couldn't find the equivalent API here : http://libvirt.org/html/libvirt-libvirt.html So, is there an API to clone an existing VM or not? Thank you! Regards 2010-11-10 Lancer -- libvir-list mailing list libvir-list(a)redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

[libvirt] First Virsh command Reference Pages online
by Justin Clift 13 Nov '10

13 Nov '10

Hi all, Started work on a Virsh "Command Reference" a few days ago, as a way to "Officially Document" (!) the many virsh commands. My plan is to add to the commands here as I work on related sections. So, as I'm working on "Virtual Networking" at the moment, it's the net-* commands that have been added. This is a first go, and it's on the wiki: http://wiki.libvirt.org/page/VirshCmdRef The net-* commands there should all be accurate at this point: http://wiki.libvirt.org/page/VirshCmdNetAutostart http://wiki.libvirt.org/page/VirshCmdNetCreate http://wiki.libvirt.org/page/VirshCmdNetDefine http://wiki.libvirt.org/page/VirshCmdNetDestroy http://wiki.libvirt.org/page/VirshCmdNetDumpXML http://wiki.libvirt.org/page/VirshCmdNetEdit http://wiki.libvirt.org/page/VirshCmdNetList http://wiki.libvirt.org/page/VirshCmdNetName http://wiki.libvirt.org/page/VirshCmdNetStart http://wiki.libvirt.org/page/VirshCmdNetUndefine http://wiki.libvirt.org/page/VirshCmdNetUUID Does anyone have time to look over them, and make sure there aren't any obvious mistakes? If things are ok, I'll convert them to standard HTML tomorrow and move them to the main libvirt docs. Regards and best wishes, Justin Clift

[libvirt] boostrap: gzip version check problem on FreeBSD
by Matthias Bolte 13 Nov '10

13 Nov '10

boostrap.conf lists gzip as build dependency. bootstrap then tries to get it's version number using a get_version() function that executes 'gzio --version' and tries to parse the result. The sed expression expects the version number to contain a dot as gzip outputs it on Linux: $ gzip --version gzip 1.3.12 But on FreeBSD it outputs this: # gzip --version FreeBSD gzip 20100407 Therefore, the sed expression should be relaxed, or bootstrap should not try to parse the version number when it doesn't need it because gzip is listed with '-' as version requirement.
