[libvirt] [PATCH v2 0/8] Add throttle blkio cgroup support for libvirt
by Gao feng 21 Jan '14

21 Jan '14

Right now, libvirt only supports the cfq based blkio cgorup, this means if the block devices doesn't use cfq scheduler, the blkio cgroup will loss effect. This patchset adds the throttle blkio cgroup support for libvirt, introduces four elements for domain configuration and extend the virsh command blkiotune. This patchset is a new version of Guan Qiang's patchset ://www.redhat.com/archives/libvir-list/2013-October/msg01066.html Change from v1: 1, rearrange the order of patches 2, change the options/elements of throttle blkio cgroup to consist with disk iotune. 3, fix complie error when cgroup is unavailable. 4, remove virCgroupSetBlkioDevice, split virCgroupSetBlkioDeviceBps and virCgroupSetBlkioDeviceIops Change from Guan Qiang's patchset: 1, split to 8 patches, make logic more clear 2, change the type of read/write iops form unsigned long long to unsigned int, trying to set read/write iops to the value which bigger than max number of unsigned int will fail. 3, fix some logic shortage. Gao feng (8): rename virDomainBlkioDeviceWeightParseXML to virDomainBlkioDeviceParseXML rename virBlkioDeviceWeightArrayClear to virBlkioDeviceArrayClear rename virBlkioDeviceWeightPtr to virBlkioDevicePtr domain: introduce xml elements for throttle blkio cgroup blkio: Setting throttle blkio cgroup for domain virsh: add setting throttle blkio cgroup option to blkiotune qemu: allow to setup throttle blkio cgroup through virsh lxc: allow to setup throttle blkio cgroup through virsh docs/schemas/domaincommon.rng | 28 +- include/libvirt/libvirt.h.in | 45 ++ src/conf/domain_conf.c | 113 +++- src/conf/domain_conf.h | 16 +- src/libvirt_private.syms | 6 +- src/lxc/lxc_cgroup.c | 29 +- src/lxc/lxc_driver.c | 649 ++++++++++++++++++++- src/qemu/qemu_cgroup.c | 29 +- src/qemu/qemu_driver.c | 443 ++++++++++++-- src/util/vircgroup.c | 224 ++++++- src/util/vircgroup.h | 16 + .../qemuxml2argv-blkiotune-device.xml | 8 + tools/virsh-domain.c | 64 ++ tools/virsh.pod | 36 +- 14 files changed, 1583 insertions(+), 123 deletions(-) -- 1.8.3.1

[libvirt] 'host-passthrough' for arm64
by Oleg Strikov 20 Jan '14

20 Jan '14

Hello guys, I'm trying to come up with basic OpenStack support for arm64 node. I'd like to use 'libvirt_cpu_mode=host-passthrough' configuration option with Nova which issues <cpu mode='host-passthrough'> to libvirt xml config. But with this option passed libvirt crashes with 'error: unsupported configuration: CPU specification not supported by hypervisor'. This happens because the following handlers are not implemented (or implemented as stubs) inside src/cpu/cpu_aarch64.c: * AArch64Decode() * AArch64Update() * AArch64guestData() To solve exactly this 'host-passthrough'-related issue that's enough to have the following set of handlers: AArch64Decode(<...>) { virCheckFlags(VIR_CONNECT_BASELINE_CPU_EXPAND_FEATURES, -1); /* I don't know any way to detect 'cortex-a57' or any other armv8 CPU for now */ /* But I don't think that we can meet anything else than cortex-a57 */ /* We may also put 'host' there to specifically point out that qemu-aarch64 supports only '-cpu host' for now */ /* pm215 told me that the ETA for '-cpu cortex-a57' and friends is around 3 months from now */ return !(VIR_STRDUP(cpu->model, "host" or "cortex-a57") == 1); } static int AArch64Update(<...>) { /* qemu-aarch64 supports only '-cpu host' for now */ guest->match = VIR_CPU_MATCH_EXACT; virCPUDefFreeModel(guest); return virCPUDefCopyModel(guest, host, true); } static virCPUCompareResult AArch64guestData(<..>) { return VIR_CPU_COMPARE_IDENTICAL; } That's clear that these handlers provide just basic functionality ('host-passthrough'-only) and have to be extended in future. But is it something we can commit for now? Another way to deal with this issue is to adopt some code from PPC handlers (including CPU model detection and best fit qemu configuration discovery). But this way will be blocked until: (1) I find any way to reliably detect CPU model on ARMv8 board (any ideas?) (2) pm215 implements TCG for arm64 What is the best way to choose to come up with the commitable code? Many thanks for your help! Oleg

[libvirt] [RFC PATCH 0/3] Implement two-tier driver loading
by Adam Walters 20 Jan '14

20 Jan '14

This patchset implements a two-tier driver loading system. I split the hypervisor drivers out into their own tier, which is loaded after the other drivers. This has the net effect of ensuring that things like secrets, networks, etc., are initialized and auto-started before any hypervisors, such as qemu, lxc, etc., are touched. This resolves the race condition present when starting libvirtd while domains are running, which happens when restarting libvirtd after having started at least one domain. This patch will work without my config driver patchset, but does prevent RBD storage pools from auto-starting. It may also affect other pool types, but I only have file and RBD to test with, personally. The RBD storage pool is only affected because it requires a hypervisor connection (prior to this patchset, that connection was hardcoded to be a connection to qemu on localhost) in order to look up secrets. Any pool type that does not use/need data outside of the base storage pool definition should continue to auto-start (file backed pools definitely still work) and also no longer be part of the restart race condition. For anyone who is not familiar with the race condition I mentioned above, the basic description is the upon restarting libvirtd, any running QEMU domains using storage pool backed disks are killed (randomly) due to their storage pool not being online. This is due to storage pool auto-start not having finished before QEMU initalization runs. I would appreciate any comments and suggestions about this patchset. It works for me on 4 machines running three different distros of Linux (Archlinux, Gentoo, and CentOS), so I would imagine it should work most anywhere.

[libvirt] How to configure MacVtap passthrough mode to SR-IOV VF?
by opendaylight 20 Jan '14

20 Jan '14

Hi guys. These days I'm doing research on SR-IOV & Live migration. As we all know there is big problem that SR-IOV & Live migration can not exist at the same time. I heard that KVM + SRIOV + MacVtap can solve this problem. So I want to try. My environment: Host: Dell R610, OS: RHEL 6.4 ( kernel 2.6.32) NIC: intel 82599 I follow a document from intel guy, it said that I should write xml like below: ============================ <network> <name>macvtap_passthrough’</name> <forward mode=’passthrough> <interface dev=’vf0’ /> <interface dev=’vf1’ /> .. .. </forward> </network> ============================ I guess here the vf0 & vf1 should be the VFs of Intel 82599. What make me confused is that we know we can not see the vf 0 & vf 1 directly from the host server with "ifconfig", that is to say, vf 0 & vf1 are not a real physical interface. I try #: virsh net-define macvtap_passthrough.xml #: virsh net-start macvtap_passthrough When I try to configure macvtap_passthrough for a VNIC of a VM, the virt-manager told : "Can't get vf 0, no such a device". When I try from virt-manager: add hardware--->network--->host device (macvtap_passthrough:pass_through network), I got error like : "Error adding device: xmlParseDoc() failed". I guess I can not write like this " <interface dev=’vf0’ />" in the xml. I try to change as below, but the result is same. ============================ <network> <name>macvtap_passthrough’</name> <forward mode=’passthrough> <pf dev=’p2p1’ /> // p2p1 is intel sriov physical nic </forward> </network> ============================ I don't know how to write correctly. Please help me. You can refer to intel document as below. Many thanks. ==========document from intel======================== Linux/KVM VM Live Migration (SRIOV And MacVtap) By Waseem Ahmad (waseem.ahmad(a)intel.com In this scenario we are using 3 machines:  Server 1: DNS/NFS – nfs.vtt.priv  Server 2: Hv1  Server3: Hv2 HV1 and HV2 are Linux/KVM machines. We will get to them in a minute however we first must address kvm and nfs. NFS:  Create a storage area, where both HV1, and HV2 can access it. There are several methods available for this (FCOE/ISCSI/NFS). For this write-up use nfs. Configure NFS:  Create a directory on nfs.vtt.priv where you want your storage to be. In this case used /home/vmstorage  Edit /etc/exports and add the following /home/vmstorage 172.0.0.0/1(rw,no_root_squash,sync)  Now to /etc/sysconfig/nfs Uncomment RPCNFSDARGS=”-N 4” This will disable nfs v4. If you don’t do this you will have issues with not being able to access the share from within VirtManager.  Add all three machines ip addresses to each machines /hosts file. MIGRATION WILL NOT WORK WITHOUT FULLY QUALIFIED DOMAIN NAMES. KVM: On both HV1, and HV2 servers:  Edit /etc/selinux/config SELINUX=disabled  Edit /etc/libvirt/qemu.conf Change security_driver=none  On HV1 and HV2 start Virtual Machine Manager  Double click on localhost(QEMU)  Then click on the storage tab at the top of the window that pops up  Down in the left hand corner is a box with a + sign in it, click on that. A new window will appear entitled Add a New Storage Pool  In the name box type vmstorage, then click on the type box and select netfs: Network Exported Directory, now click next.  You will see the last step of the network Storage Pool Dialog. The first option is the target path. This is the path where we will mount our storage on the local server. I have chosen to leave this alone.  The next option is format, leave this set on auto: Host name: nfs.vtt.priv Source path: /home/vmstorage  Click on finish  Repeat the above steps on HV2 server Create vms  On HV1 server go back to the connection details screen, (this is the one that showed up when you double clicked on localhost (qemu), and click on the storage tab again.  Click on vmstorage then click on new volume at the bottom.  A new dialog will appear entitled add a storage volume.  In the Name box type vm1  In the Max Capacity box type 20000  And do the same in the allocation box then click finish.  Now you can close the connection details box by click on the x in the corner.  Now click on the terminal in the corner, right underneath file, and type the name of our vm in the box that is entitled Name, vm1 choose how your installation media, probably local install media, and click forward. Click on use cdrom or dvd, and place a rh6.2 dvd in the dvd player on HV1. Select Linux, for the OS type, and Red Hat Enterprise Linux 6 for the version. Memory I chose to leave this at its default of 1024, and assigned 1 cpu to the guest. Click forward, select “select managed or other existing storage” and click the browse button. Click on vmstoarge, and select vm1.img then click forward. Then click on finish.  We will configure network after we make sure migration between the two servers works properly.  Now go ahead and install the operating system as you would normally. Create networks Create a file that looks like the following < there is no support for adding a macvtap interface from the gui as of yet, this is the only manual step in the process. Create a file named macvtap_passthrough.xml with the following contents. <network> <name>macvtap_passthrough’</name> <forward mode=’passthrough> <interface dev=’vf0’ /> <interface dev=’vf1’ /> .. .. </forward> </network> <network> <name>’macvtap_bridge’</name> <forward mode=’bridge’> <interface dev=’p3p1’/> </forward> </network> Save it and run the following commands:  virsh net-define macvtap_passthrough.xml  virsh net-start macvtap_passthrough Make sure all of your virtual interfaces that you used in the xml file are up. for i in $(ifconfig –a | awk ‘/eth/ {print $1}’); do ifconfig $i up; done Then double click on your vm and click on the big blue i On the next screen click on add hardware, then on network, then select Virtual network “macvtap_passthrough” Then click on finish. Start your vm and make sure that the macvtap was created on the host by doing ip link | grep ‘macvtap’ In the vm configure the ip information for the virtio adapter. In the virtual machine manager click on file, add connection. Then check the connect to remote host fill in the username and hostname, then click on connect Right click on your VM and select Migrate, select the host you want to migrate the machine to, then click on advanced options, check the address box, and type the ip address of the machine you want to migrate to, and click the migrate button.

The last patch is a tad quirky (happy to hear suggestions on alternative ways), in that it widens the permissible value set at the .domainBlockStats slot: for lxc guests, it is relatively likely to have zero disk devices, since host filesystems can be used via passthrough bind mounts. Therefore, passing the null ptr or the zero-length string as device path, is interpreted as 'return summary stats for the entire domains's block io'. Thorsten Behrens (6): Add util virCgroupGetBlkioIo*Serviced methods. Implement domainMemoryStats API slot for LXC driver. Make qemuGetDomainTotalCPUStats a virCgroup function. Implement domainGetCPUStats for lxc driver.

[libvirt] [libvirt-glib] Fix GVirConfigDomainTimerPit parent class/object
by Christophe Fergeau 18 Jan '14

18 Jan '14

GVirConfigDomainTimerPit is correctly define as inheriting from GVirConfigDomainTimer in the G_DEFINE_TYPE macro, but it only embeds GVirConfigObject/GVirConfigObjectClass structs. This is an ABI break as this changes the size of the GVirConfigDomainTimerPit/GVirConfigDomainTimerPitClass structs However, since these structs only have non-public members, users of the library will not be trying to access fields of the struct past the first field (which is the one which changed size). This would also be an issue if anything had subclassed GVirConfigDomainTimerPit, which is unlikely at this point. All in all, it's imo more convenient to silently fix this without an soname bump. I've tested that GNOME Boxes built with an older version of libvirt-gconfig still generates the correct GVirConfigDomainTimerPit elements when using a version of libvirt-gconfig with this patch. --- libvirt-gconfig/libvirt-gconfig-domain-timer-pit.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/libvirt-gconfig/libvirt-gconfig-domain-timer-pit.h b/libvirt-gconfig/libvirt-gconfig-domain-timer-pit.h index b644c52..7802ac4 100644 --- a/libvirt-gconfig/libvirt-gconfig-domain-timer-pit.h +++ b/libvirt-gconfig/libvirt-gconfig-domain-timer-pit.h @@ -42,7 +42,7 @@ typedef struct _GVirConfigDomainTimerPitClass GVirConfigDomainTimerPitClass; struct _GVirConfigDomainTimerPit { - GVirConfigObject parent; + GVirConfigDomainTimer parent; GVirConfigDomainTimerPitPrivate *priv; @@ -51,7 +51,7 @@ struct _GVirConfigDomainTimerPit struct _GVirConfigDomainTimerPitClass { - GVirConfigObjectClass parent_class; + GVirConfigDomainTimerClass parent_class; gpointer padding[20]; }; -- 1.8.4.2

[libvirt] [libvirt-glib 0/4] Add API to build <timer name="hpet" present="no"/>
by Christophe Fergeau 18 Jan '14

This series allows to generate <timer name="hpet" present="no"/> using libvirt-gconfig. This is a prerequisite for fixing this Boxes bug https://bugzilla.gnome.org/show_bug.cgi?id=722293 Patch 2/4 doesn't anything to do in this series, but this was easy to implement after 1/4 so I slipped it there.

[libvirt] [PATCH] build: add $(prefix) to SYSTEMD_UNIT_DIR
by Laine Stump 17 Jan '14

17 Jan '14

I noticed this problem when adding systemd support to netcf, because I setup the configure.ac to automatically prefer using systemd over initscripts when possible - although I had copied the install-data-local target from the example of libvirt's "libvirt-guests" service more or less verbatim, "make distcheck" would fail because it was trying to install the service file directly into /lib/systemd/system rather than into /home/user/some/unimportant/name/lib/systemd/system. This is caused by the install/uninstall rules for the systemd unit files relying on $(DESTDIR) pointing the installed files to the right place, but in reality $(DESTDIR) is empty during this part of make distcheck - it instead sets $(prefix) with the toplevel directory used for its test build/install/uninstall cycle. (This problem hasn't been seen when running "make distcheck" in libvirt because libvirt will never build/install systemd support unless explicitly told to do so on the configure commandline, and "make distcheck" doesn't put the "--with-initscript=..." option on the configure commandline.) I verified that the same problem does exist in libvirt by modifying libvirt's configure.ac to set: init_systemd=yes with_init_script=systemd+redhat This forces a build/install of the systemd unit files during distcheck, which yields an error like this: /usr/bin/install -c -m 644 virtlockd.service \ /lib/systemd/system/ libtool: install: warning: relinking `libvirt-qemu.la' /usr/bin/install: cannot remove '/lib/systemd/system/virtlockd.service': Permission denied make[4]: *** [install-systemd] Error 1 After adding $(prefix) to all the definitions of SYSTEMD_UNIT_DIR, make distcheck now completes successfully with the modified configure.ac, and the above lines change to something like this: /usr/bin/install -c -m 644 virtlockd.service \ /home/laine/devel/libvirt/libvirt-1.2.1/_inst/lib/systemd/system/ --- daemon/Makefile.am | 4 ++-- src/Makefile.am | 4 ++-- tools/Makefile.am | 4 ++-- 3 files changed, 6 insertions(+), 6 deletions(-) diff --git a/daemon/Makefile.am b/daemon/Makefile.am index e5c5db8..00221ab 100644 --- a/daemon/Makefile.am +++ b/daemon/Makefile.am @@ -1,6 +1,6 @@ ## Process this file with automake to produce Makefile.in -## Copyright (C) 2005-2013 Red Hat, Inc. +## Copyright (C) 2005-2014 Red Hat, Inc. ## ## This library is free software; you can redistribute it and/or ## modify it under the terms of the GNU Lesser General Public @@ -387,7 +387,7 @@ endif !

[libvirt] Libvirt Security Notices
by Daniel P. Berrange 17 Jan '14

17 Jan '14

Hi Folks, After much work I've finally got a formal Libvirt Security Notice (LSN) setup worked out. Every security issue that is reported & confirmed on the libvirt security mailing list will have a formal LSN prepared. This is a simple XML document containing metadata & other information about the issue we deem relevant. Initially this will be private if there is an embargo applied. Once the issue is made public, will the LSN notices will be added to the following public GIT repository: http://libvirt.org/git/?p=libvirt-security-notice.git;a=summary This GIT repository is used to populate a new public website http://security.libvirt.org/ A plain text rendering of the LSN will also be sent to the mailing list libvirt-announce(a)redhat.com Every issue is available in text, html and xml formats eg http://security.libvirt.org/2014/0002.txt http://security.libvirt.org/2014/0002.html http://security.libvirt.org/2014/0002.xml If anyone backports a fix for a security issue to various -maint branches, the LSN notice in GIT should be updated with GIT hash of the backports. If a maint release is created, the tag should also be added to the LSN. After countless hours investigation I have populated the repository with a list of all historical issues in libvirt that I'm aware of.

[libvirt] Add GVirConfigDomainDiskDriver
by Christophe Fergeau 17 Jan '14

17 Jan '14

Hey, I wanted to add support in libvirt-gconfig for the 'discard' attribute of the disk driver node. If I follow the way the API is currently done, it would be an additional method to GVirConfigDomainDisk. However, there are quite a few attributes attached to the disk driver node, so I felt it was preferrable to have a dedicated GVirConfigDomainDiskDriver class. This also matches better other places of libvirt-gconfig API. I've implemented support for most of the attributes of the disk driver node, as a result the corresponding methods in GVirConfigDomainDisk have been deprecated. Christophe

[libvirt] [PATCH] virSecuritySELinuxSetFileconHelper: Don't fail on read-only NFS
by Michal Privoznik 17 Jan '14

17 Jan '14

https://bugzilla.redhat.com/show_bug.cgi?id=996543 When starting up a domain, the SELinux labeling is done depending on current configuration. If the labeling fails we check for possible causes, as not all labeling failures are fatal. For example, if the labeled file is on NFS which lacks SELinux support, the file can still be readable to qemu process. These cases are distinguished by the errno code: NFS without SELinux support returns EOPNOTSUPP. However, we were missing one scenario. In case there's a read-only disk on a read-only NFS (and possibly any FS) and the labeling is just optional (not explicitly requested in the XML) there's no need to make the labeling error fatal. In other words, read-only file on read-only NFS can fail to be labeled, but be readable at the same time.

[libvirt] On Archbsd which uses Freebsd10 kernel and world the libvirt-glib with enable-introspection does not compile (using gcc or clang)
by Claudiu Traistaru 17 Jan '14

I have already posted a bug request about this. https://bugzilla.redhat.com/show_bug.cgi?id=1054657 The issue appears when trying to build with --enable-introspections flag. I think it would be super if somebody had a solution for this, because virt-manager is an nice tool to have.

[libvirt] [libvirt-glib] config: Fix typo preventing clock removal from a domain
by Christophe Fergeau 16 Jan '14

Commit 1c8ce29 added a way to unset a GVirConfigDomainClock set on a GVirConfigDomain by calling gvir_config_domain_set_clock() with a NULL argument. However, a typo in a g_return_if_fail precondition prevents this code from ever being called: g_return_if_fail(clock != NULL) is used while it should have been g_return_if_fail(clock == NULL) as in all other preconditions in 1c8ce29. --- libvirt-gconfig/libvirt-gconfig-domain.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libvirt-gconfig/libvirt-gconfig-domain.c b/libvirt-gconfig/libvirt-gconfig-domain.c index 3c28a4a..6cd2f86 100644 --- a/libvirt-gconfig/libvirt-gconfig-domain.c +++ b/libvirt-gconfig/libvirt-gconfig-domain.c @@ -552,7 +552,7 @@ void gvir_config_domain_set_clock(GVirConfigDomain *domain, GVirConfigDomainClock *klock) { g_return_if_fail(GVIR_CONFIG_IS_DOMAIN(domain)); - g_return_if_fail(klock != NULL || GVIR_CONFIG_IS_DOMAIN_CLOCK(klock)); + g_return_if_fail(klock == NULL || GVIR_CONFIG_IS_DOMAIN_CLOCK(klock)); gvir_config_object_attach_replace(GVIR_CONFIG_OBJECT(domain), "clock", -- 1.8.4.2

v2 of my patch series started here, after applying all patches already reviewed in that thread: https://www.redhat.com/archives/libvir-list/2013-December/msg01284.html Patches 1-3 can be considered bug fixes (particularly patch 3), so I'd like them in 1.2.1 if they get a favorable review. Patches 4-6 are less urgent, but might as well finish the work all within one release.

16 Jan '14

Hi all, We've created a new wiki page [1] where we would like to create a list of areas that we should focus on testing. If there is something critical or important what you think that should be really tested please feel free to update the wiki page. You should write down what part or functionality of libvirt should be tested and how do you think it should be tested. Regards, Pavel [1] <http://wiki.libvirt.org/page/AreasToFocusOnTesting>

[libvirt] [PATCH] virsh nodecpustats returns incorrect stats of cpu on Linux when the number of online cpu exceed 9.
by mars＠linux.vnet.ibm.com 16 Jan '14

16 Jan '14

From: Bing Bu Cao <mars(a)linux.vnet.ibm.com> To retrieve node cpu statistics on Linux system, the linuxNodeGetCPUstats function simply uses STRPREFIX() to match the cpuid with the cpuid read from /proc/stat, it will cause obvious error. For example: 'virsh nodecpustats 1' will display stats of cpu1* if the latter is online and cpu1 is offline. This patch fixes this bug.

[libvirt] [PATCH v2] lxcDomainShutdownFlags and lxcDomainReboot: Cleanup @flags usage

[libvirt] About libvirt.py stdout redirection
by me,apporc 16 Jan '14

16 Jan '14

Dear developers, As we know libvirt.py using libvirtmod.so, eg: def defineXML(self, xml): """Define a domain, but does not start it. This definition is persistent, until explicitly undefined with virDomainUndefine(). A previous definition for this domain would be overriden if it already exists. """ ret = libvirtmod.virDomainDefineXML(self._o, xml) if ret is None:raise libvirtError('virDomainDefineXML() failed', conn=self) __tmp = virDomain(self,_obj=ret) return __tmp In my python program #test.py import libvirt conn=libvirt.open("qemu:///system") xml=... conn.defineXML(xml) # Because i need this xml to be wrong for feature testing here # Error will happen here, and error message is printed to stderr. The error message is annoying. I need to know how to hide the error message printing to stderr by libvirtmod. After i add sys.stderr = open('xxx', 'w') before invoking conn.defineXML(xml), the error message is still printed to the terminal. Which means, i can redirect stderr to anywhere else in my python program, but it changes back to terminal when control flow go to libvirtmod. Any ideas? -- Regards, apporc

[libvirt] [PATCH 0/4] CVE-2014-0028: domain events vs. ACL filtering
by Eric Blake 16 Jan '14

16 Jan '14

I have pushed the following series to the master branch, as well as the the backport of patch 4 to all branches impacted by the CVE (v1.1.0 onwards). Basically, when ACLs permit fine-grained control of what domains a user can manage, a user that was denied domain:getattr for a particular domain, or denied connect:search_domains in general, could use the event registration API to gain access to domains that should have been hidden from that user. The patch was reviewed offlist during the time when the vulnerability was under embargo. In the process of fixing this, I made quite a few improvements to the underlying mechanisms for events. Among other things, I want to switch libvirt over to using server-side filtering rather than the current implementation of client-side filtering, for increased efficiency in the case where a hypervisor hosts many guests but the client only cares about events on a small subset of those guests. The existing RPC calls for domain events did not allow this, but the brand new network events had not yet had their RPC baked with a formal release. At one point, I had tried making the use of connect:search_networks conditional on whether a non-NULL network had been requested, which requires server-side filtering. The final incarnation of the CVE fix no longer bypasses connect:search_networks for a NULL network, so the first three patches are now technically unrelated to the CVE fix; but as the work is already done and reviewed and as it is easier to avoid bloat in the RPC protocol by getting it right from the beginning, I still pushed those patches to the master branch. NOTE: if you were testing network events with libvirt.git or with the 1.2.1 release candidates, you must ensure that you match your client's use of libvirt.so with the libvirtd - early users of network events are unable to communicate with the RPC wire representation that will actually be in 1.2.1 as a result of this series. I will also be posting a followup series, for application after 1.2.1 is released, which adds server-side filtering of domain events, as the counterpart of the network event filtering added in this series. There, we already have existing RPC code baked into releases, so there is no longer a rush to get the patches in before a release freezes a mistake.

[libvirt] [PATCH 0/5] server-side filtering of domain events
by Eric Blake 16 Jan '14

16 Jan '14

This work was originally done with the thought that the fix for CVE-2014-0028 would require server-side filtering to make the check of connect:search_domains conditional on whether the user passed NULL or a domain when registering for an event. The final version of the CVE fix no longer needs the conditional behavior, so there is no longer a rush to get this in to 1.2.1; but for 1.2.2, the code changes offer a nice efficiency gain for the use case of libvirtd managing lots of domains while a client only cares about events from a small subset of domains. While this will not be in 1.2.1 proper, I also tested that the entire series can be backported without breaking the .so versioning, if any downstream distro wants to include the efficiency gain as part of their value added maintenance of an older version.

[libvirt] [PATCH] BSD: implement nodeGetCPUStats
by Roman Bogorodskiy 15 Jan '14

15 Jan '14

I had doubts how to implement that. Looks like the current implementation is tied to Linux CPU metrics: user nice system idle iowait That list is hardcoded into virsh-host.c. FreeBSD has a slightly different set of metrics: user nice system intr idle I.e. it's interrupt time instead of i/o time. I decided to go without virsh-host.c modification and used VIR_NODE_CPU_STATS_UTILIZATION. If you know better way of doing that, I'm open for suggestions.

[libvirt] [PATCHv2] tests: be more explicit on qcow2 versions in virstoragetest
by Eric Blake 15 Jan '14

15 Jan '14

While working on v1.0.5-maint (the branch in use on Fedora 19) with the host at Fedora 20, I got a failure in virstoragetest. I traced it to the fact that we were using qemu-img to create a qcow2 file, but qemu-img changed from creating v2 files by default in F19 to creating v3 files in F20. Rather than leaving it up to qemu-img, it is better to write the test to force testing of BOTH file formats (better code coverage and all). This patch alone does not fix all the failures in v1.0.5-maint; for that, we must decide to either teach the older branch to understand v3 files, or to reject them outright as unsupported. But for upstream, making the test less dependent on changing qemu-img defaults is always a good thing. * tests/virstoragetest.c (testPrepImages): Simplify creation of raw file; check if qemu supports compat and if so use it.

[libvirt] [PATCH v2] vbox: add support for v4.2.20+ and v4.3.4+
by Manuel VIVES 15 Jan '14

15 Jan '14

Hi, While working on adding virDomain*Stats support to the vbox driver, we found bugs in the VirtualBox API C bindings. These bugs have been fixed in versions 4.2.20 and 4.3.4. However, the changes in the C bindings are incompatible with the vbox_CAPI_v4_2.h and vbox_CAPI_v4_3.h files which are bundled in libvirt source code. This is why the following patch adds vbox_CAPI_v4_2_20.h and vbox_CAPI_v4_3_4.h. As stated by Matthias Bolte, the actual underlying problem here is that libvirt assumes that VirtualBox API can only change between release versions (4.2 -> 4.3), but we have a case here where it changed (or got fixed) between minor versions (4.2.18 -> 4.2.20). This patch makes the VBOX_API_VERSION represent the full API version number (i.e 4002 => 4002000) so there are specific version numbers for Vbox 4.2.20 (4002020) and 4.3.4 (4003004) As the patch is too big for the mailing list, it is publicly available at http://git-lab.diateam.net/cots/libvirt.git/ with the branch name 'vbox-4.2.20-4.3.4-support-v2' Regards, Manuel VIVES

[libvirt] [PATCH] Really don't crash if a connection closes early
by Jiri Denemark 15 Jan '14

15 Jan '14

https://bugzilla.redhat.com/show_bug.cgi?id=1047577 When writing commit 173c291, I missed the fact virNetServerClientClose unlocks the client object before actually clearing client->sock and thus it is possible to hit a window when client->keepalive is NULL while client->sock is not NULL. I was thinking client->sock == NULL was a better check for a closed connection but apparently we have to go with client->keepalive == NULL to actually fix the crash.

[libvirt] [PATCH] Add helper program to create custom leases
by Nehal J Wani 14 Jan '14

14 Jan '14

Introduce helper program to catch events from dnsmasq and maintain a custom lease file per network. It supports dhcpv4 and dhcpv6. The file is saved as "<interface-name>.status". The format of each lease is: <expiry-time (epoch time)> <mac> <iaid> <ip-address> <hostname> <clientid> Example of custom leases file content: 1385245780 52:54:00:2f:ba:76 * 192.168.150.153 * * 1385245781 52:54:00:2f:ba:76 3127926 2001:db8:ca2:2:1::6c * 00:04:76:00:cf:ae:b3:0b:fc:cd:0e:22:2e:97:76:65:74:ec 1385245964 52:54:00:44:7c:d7 * 192.168.150.219 iiit-ad885e4aa1 01:52:54:00:44:7c:d7 1385245964 52:54:00:44:7c:d7 * 192.168.150.219 * 01:52:54:00:44:7c:d7 1385246016 52:54:00:5d:99:92 * 192.168.150.212 iiit-ad885e4aa1 01:52:54:00:5d:99:92 1385246041 52:54:00:3b:16:e0 * 192.168.150.207 * * 1385246081 52:54:00:db:dd:98 * 192.168.150.234 * * 1385246088 52:54:00:db:dd:98 14409112 2001:db8:ca2:2:1::6d * 00:04:76:00:cf:ae:b3:0b:fc:cd:0e:22:2e:97:76:65:74:ec --- src/util/leaseshelper.c | 232 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 232 insertions(+) create mode 100644 src/util/leaseshelper.c diff --git a/src/util/leaseshelper.c b/src/util/leaseshelper.c new file mode 100644 index 0000000..9ed22a6 --- /dev/null +++ b/src/util/leaseshelper.c @@ -0,0 +1,232 @@ +/* + * leasehelper.c: Helper program to create custom leases file + * + * Copyright (C) 2013 Red Hat, Inc. + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[libvirt] [PATCH v2] conf: Always use VIR_ERR_CONFIG_UNSUPPORTED on enumFromString() failures

Currently, during XML parsing, when a call to a FromString() function to get an enum value fails, the error which is reported is either VIR_ERR_CONFIG_UNSUPPORTED, VIR_ERR_INTERNAL_ERROR or VIR_ERR_XML_ERROR.

[libvirt] [PATCH] vbox: add support for v4.2.20+ and v4.3.4+
by Jean-Baptiste Rouault 14 Jan '14

14 Jan '14

While working on adding virDomain*Stats support to the vbox driver, we found bugs in the VirtualBox API C bindings. These bugs have been fixed in versions 4.2.20 and 4.3.4. However, the changes in the C bindings are incompatible with the vbox_CAPI_v4_2.h and vbox_CAPI_v4_3.h files which are bundled in libvirt source code. This is why the following patch adds vbox_CAPI_v4_2_20.h and vbox_CAPI_v4_3_4.h. We tried to keep compatibility with older VirtualBox 4.2.x and 4.3.x releases so we added a "SPECIAL_VERSION" identifier to conditionnaly include the right header. I'm not really pleased with this "SPECIAL_VERSION" identifier, maybe we could instead increase the precision of "VBOX_API_VERSION", for example 4002 would become 4002000. This would permit us to select the right header based on the VBOX_API_VERSION only, what do you think ?

[libvirt] libvirt on armhf with selinux driver
by Ivan Gooten 14 Jan '14

14 Jan '14

hi, recently i've been busy with libvirt(d) v1.2.0 and v1.2.1 from GIT on armhf and i see, even if selinux sec driver is enabled on the configure stage, the driver is not finally created. i pass these configure parameters: --with-selinux --with-secdriver-selinux --with-selinux-mount=/sys/fs/selinux the /sys/fs/selinux is valid, selinux is running in permissive mode, got also libselinux DEV package installed, so no missing req. headers here. when trying to run libvirtd, i'm getting: error : virSecurityDriverLookup:78 : unsupported configuration: Security driver selinux not enabled error : lxcSecurityInit:1461 : Failed to initialise security drivers error : virStateInitialize:854 : Initialisation of LXC state driver failed: unsupported configuration: Security driver selinux not enabled error : daemonRunStateInit:909 : Driver state initialisation failed here i provide the configure summary: http://pastebin.com/un0UnFCP for me it looks okay, and below is is the sestatus: SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: default Current mode: permissive Mode from config file: permissive Policy MLS status: enabled Policy deny_unknown status: allowed Max kernel policy version: 28 the platform is running custom kernel 3.10 with debian testing a.k.a. jessie. also, my friend with the same configuration on rpi, except for his newer kernel, is having same stranginess. someone got any clue what may be causing this and/or howto debug this? thanks, ivan gooten

[libvirt] [PATCH] build: fix build on mingw with winpthreads
by Eric Blake 13 Jan '14

13 Jan '14

On my Fedora 20 box with mingw cross-compiler, the build failed with: ../../src/rpc/virnetclient.c: In function 'virNetClientSetTLSSession': ../../src/rpc/virnetclient.c:745:14: error: unused variable 'oldmask' [-Werror=unused-variable] sigset_t oldmask, blockedsigs; ^ I traced it to the fact that mingw64-winpthreads installs a header that does #define pthread_sigmask(...) 0, which means any argument only ever passeed to pthread_sigmask is reported as unused.

[libvirt] [PATCH] Don't crash if a connection closes early
by Jiri Denemark 13 Jan '14

13 Jan '14

https://bugzilla.redhat.com/show_bug.cgi?id=1047577 When a client closes its connection to libvirtd early during virConnectOpen, more specifically just after making REMOTE_PROC_CONNECT_SUPPORTS_FEATURE call to check if VIR_DRV_FEATURE_PROGRAM_KEEPALIVE is supported without even waiting for the result, libvirtd may crash due to a race in keep-alive initialization. Once receiving the REMOTE_PROC_CONNECT_SUPPORTS_FEATURE call, the daemon's event loop delegates it to a worker thread. In case the event loop detects EOF on the connection and calls virNetServerClientClose before the worker thread starts to handle REMOTE_PROC_CONNECT_SUPPORTS_FEATURE call, client->keepalive will be disposed by the time virNetServerClientStartKeepAlive gets called from remoteDispatchConnectSupportsFeature. Because the flow is common for both authenticated and read-only connections, even unprivileged clients may cause the daemon to crash. To void the crash, virNetServerClientStartKeepAlive needs to check if the connection is still open before starting keep-alive protocol. Every libvirt release since 0.9.8 is affected by this bug.

[libvirt] [PATCH] Exercise the ABI stability check code in test suite

Any test suite which involves a virDomainDefPtr should call virDomainDefCheckABIStability with itself just as a basic sanity check that the identity-comparison always succeeds. This would have caught the recent NULL pointer access crash. Make sure we cope with def->name being NULL since the VMWare config parser produces NULL names. Signed-off-by: Daniel P.

[libvirt] [PATCH] conf: Always use VIR_ERR_XML_ERROR on enumFromString() failures

[libvirt] [v9 0/6] Write separate module for hostdev passthrough
by Chunyan Liu 10 Jan '14

These patches implements a separate module for hostdev passthrough so that it could be shared by different drivers and can maintain a global state of a host device. patch 1/6: extract hostdev passthrough function from qemu_hostdev.c and make it reusable by multiple drivers. patch 2/6: add a unit test for hostdev common library. patch 3/6: switch qemu driver to use the common library instead of its own hostdev passthrough APIs. patch 4/6: switch lxc driver to use the common library instead of its own hostdev passthrough APIs. patch 5/6: add a hostdev pci backend type for xen usage. patch 6/6: add pci passthrough to libxl driver. --- Changes * rebase to lasest source code * fix ioctl return value in virHostdevHostSupportsPassthroughKVM() Chunyan Liu (6): add hostdev passthrough common library add unit test for hostdev common library change qemu driver to use hostdev common library change lxc driver to use hostdev common library add hostdev pci backend type for xen add pci passthrough to libxl driver docs/schemas/domaincommon.rng | 1 + po/POTFILES.in | 3 +- src/Makefile.am | 3 +- src/conf/domain_conf.c | 3 +- src/conf/domain_conf.h | 1 + src/libvirt_private.syms | 21 + src/libxl/libxl_conf.c | 63 + src/libxl/libxl_conf.h | 4 + src/libxl/libxl_domain.c | 9 + src/libxl/libxl_driver.c | 448 +++++- src/lxc/lxc_conf.h | 4 - src/lxc/lxc_driver.c | 47 +- src/lxc/lxc_hostdev.c | 413 ----- src/lxc/lxc_hostdev.h | 43 - src/lxc/lxc_process.c | 24 +- src/qemu/qemu_command.c | 4 +- src/qemu/qemu_conf.h | 9 +- src/qemu/qemu_domain.c | 22 + src/qemu/qemu_driver.c | 81 +- src/qemu/qemu_hostdev.c | 1454 ----------------- src/qemu/qemu_hostdev.h | 76 - src/qemu/qemu_hotplug.c | 136 +- src/qemu/qemu_process.c | 40 +- src/util/virhostdev.c | 1703 ++++++++++++++++++++ src/util/virhostdev.h | 134 ++ src/util/virpci.c | 30 +- src/util/virpci.h | 9 +- src/util/virscsi.c | 28 +- src/util/virscsi.h | 8 +- src/util/virusb.c | 29 +- src/util/virusb.h | 8 +- tests/Makefile.am | 5 + .../qemuxml2argv-hostdev-pci-address.xml | 1 + .../qemuxml2argvdata/qemuxml2argv-net-hostdev.xml | 1 + tests/qemuxml2argvdata/qemuxml2argv-pci-rom.xml | 2 + tests/virhostdevtest.c | 481 ++++++ tests/virpcimock.c | 23 +- 37 files changed, 3159 insertions(+), 2212 deletions(-) delete mode 100644 src/lxc/lxc_hostdev.c delete mode 100644 src/lxc/lxc_hostdev.h delete mode 100644 src/qemu/qemu_hostdev.c delete mode 100644 src/qemu/qemu_hostdev.h create mode 100644 src/util/virhostdev.c create mode 100644 src/util/virhostdev.h create mode 100644 tests/virhostdevtest.c

[libvirt] [PATCH] test driver: Add authentication to test driver.
by Richard W.M. Jones 10 Jan '14

10 Jan '14

There is no easy way to test authentication against libvirt. This commit modifies the test driver to allow simple username/password authentication. You modify the test XML by adding: <node> ... <auth> <user password="123456">rich</user> <user>jane</user> </auth> </node> If there are any /node/auth/user elements, then authentication is required by the test driver (if none are present, then the test driver will work as before and not require authentication).

[libvirt] Regression testing libvirt authentication
by Richard W.M. Jones 10 Jan '14

10 Jan '14

I'm trying to find a way to regression-test a program which uses libvirt authentication (virConnectAuth, virConnectAuthPtr). Ideally the test:/// driver would be able to fake authentication demands, but it doesn't seem to be able to do that. Any suggestions? Would this feature belong in the test driver or elsewhere?

[libvirt] New feature discussion: Grouping multiple libvirt's in a "pool"
by Ahmed Ossama 10 Jan '14

10 Jan '14

Greetings All, I would like to say "Hi" to everyone on the list since this is my first message. I have couple of servers running CentOS and Debian with kvm and libvirt on top. Lately I've been thinking of coordinating them together in a pool like XenServer groups servers in a "Pool". I am totally aware that this feature can be achieved by installing OpenStack or any similar orchestrator on top of libvirt. But I would like to achieve this feature using libvirt alone as I don't want to install any stuff above libvirt. I was also thinking if each libvirt on every server is aware of other resources (Domains, Storage and Network), this could provide better support and view to any higher orchestrator utilizing libvirt. So I am wondering if such feature was discussed previously? And would like to hear thoughts or concerns about it. -- Regards, Ahmed Ossama

[libvirt] [PATCH] qemu: Add support for changing timeout value to open unix monitor socket
by Pavel Fux 10 Jan '14

10 Jan '14

Hi, I am talking about *Bug 987088*<https://bugzilla.redhat.com/show_bug.cgi?id=987088>, I have added a patch and a description of the fix, this is a copy of my comment on the bug: the default code behavior is wait for 3 seconds and if the socket is not opened yet, print this error and terminate. the code is in src/qemu/qemu_monitor.c in function qemuMonitorOpenUnix. In 2009 there was a patch that added the original 3 seconds retry, the patch can be found here: http://www.redhat.com/archives/libvir-list/2009-July/msg00335.html I have added a patch with this solution: the default behavior stays the same, but a user can add a configuration variable to qemu.conf and change the timeout value. every system needs a different value according to their system configuration but anyway 3 seconds is not suitable for all cases. I am attaching my patch. Pavel Fux.

[libvirt] [PATCH 0/2] v2: spice: expose the disable file transfer option
by Francesco Romani 10 Jan '14

10 Jan '14

Here it is the second version of the patch which export the spice agent disable file transfer. I followed Eric's advice and added detection of the support in QEMU in the first patch; the second builds upon the first and exports the support to libvirt. The XML format is intentionally similar to the 'clipboard' element, I thought the share enough similiarities; however, suggestions are more than welcome here. Please also feel free to suggest how to extend the testing, and if what was added here is enough. As everyone probably already noticed it's my first libvirt contribution; I tried to follow HACKING's advice caredully but I can have missed something (more).

[libvirt] [PATCH] event: don't queue NULL event on OOM
by Eric Blake 10 Jan '14

10 Jan '14

Ever since commit 61ac8ce, Coverity complained about remoteNetworkBuildEventLifecycle not checking for NULL failure to build an event, compared to other calls in the code base. But the problem is latent from copy and paste; all 17 of our remote*BuildEvent* functions in remote_driver.c have the same issue - if an OOM causes an event to not be built, we happily pass NULL to remoteEventQueue(), but that function has marked event as a nonnull parameter. We were getting lucky (the event queue's first use of the event happened to be a call to virIsObjectClass(), which acts gracefully on NULL, so there was no way to crash); but this is a latent bug waiting to bite us due to the disregard for the nonnull attribute, as well as a waste of resources in the event queue. Better is to just refuse to queue NULL. The discard is silent, since the problem only happens on OOM, and since events are already best effort - if we fail to get an event, it's not like we have any memory left to report the issue, nor any idea of who would benefit from knowing we couldn't create or queue the event. * src/remote/remote_driver.c (remoteEventQueue): Ignore NULL event. Signed-off-by: Eric Blake <eblake(a)redhat.com> --- I don't know if this will actually shut up Coverity, or if we have to modify all 17 calls to remoteEventQueue to do the NULL check there.

[libvirt] [PATCHv2 0/7] lxc: honor mount namespaces
by Eric Blake 10 Jan '14

10 Jan '14

We are still awaiting a CVE number to be assigned, but Reco reported in Debian bug #732394 that a malicious guest could cause virDomainShutdown and virDomainReboot to cause the host to misbehave, if the host blindly follows symlinks in its own mount namespace instead of the guest's namespace. I have not yet tried to patch the bugs in virDomainDeviceAttach dereferencing /dev from the wrong namespace, which also suffers from the same vulnerability, but virProcessRunInMountNamespace should also be usable in that situation. While working on this series, I found several issues with virFork and virt-login-shell; since those are also related to correct namespace usage, I've bundled everything into one series; but the CVE is not fixed until patch 7/7 plus the future patch to /dev. I've done some pretty decent testing on the new virt-login-shell, but did not get as much testing on virDomainReboot. Since this series does address a CVE, and also regressions caused by our previous CVE fix in the same area of code (CVE-2013-4400 is unfortunately a poor example of shipping "fixes" without testing that the code still worked), I'd definitely appreciate a close review. Patch 6/7 is interesting: it uses virFork to use the mount namespace without impacting the parent process. However, since setns() is thread-safe, I wonder if it would be simpler to instead use pthread_create to do the callback within the same process instead of having to create a separate process, as that would make for easier coordination for passing the results back to the remaining threads that have not changed namespace. Thankfully, I think we came up with a good abstraction - I'm fairly confident that 6/7 could be rewritten to use pthread_create without changing the function signatures, in which case patch 7/7 would not need any changes to pick up the changed backend.

[libvirt] [libvirt-java] [PATCH 00/15] Refactor error handling
by Claudio Bley 09 Jan '14

09 Jan '14

The error handling in libvirt-java is sort of a mess. Each and every class contains a processError() method which just forwards to ErrorHandler.processError(jna.Libvirt). Furthermore, this processError() method is often called unnecessarily after every libvirt call, although its return code did not indicate an error at all. So, this patchset removes the cruft with the added benefit of avoiding calls into native code when possible. Patch #1 starts the refactoring. It adds a few helper methods to the ErrorHandler class which will be removed by patch #15. Patch #2 to #13 are mostly mechanical, just wrapping calls of any libvirt function into a call to processError(int) or processError<T>(T). Patch #14 removes the obsolete processError(Libvirt) method. Patch #15 cleans up patch #1. Claudio Bley (15): Start refactoring of error handling Remove processError from Device class Remove processError from Domain class Remove processError from DomainSnapshot class Remove processError from Interface class Remove processError method from Network class Remove processError method from NetworkFilter class Remove processError method from Secret class Remove processError method from StoragePool class Remove processError method from StorageVol class Remove processError method from Stream class Remove processError method from Connect class Call processError only when virInitialize signalled an error Remove ErrorHandler.processError(Libvirt) method fixup!

[libvirt] [libvirt-java] [PATCH 0/2] Fixes for Device.listCapabilities
by Claudio Bley 09 Jan '14

09 Jan '14

Let the Device.listCapabilities method return an array filled with non-null string objects. Furthermore, the decoding of the character data does no longer depend upon the default JVM charset. This also fixes a memleak because the allocated memory was not freed in the old code. Patch #2 just adds a unit test which simply uses this function.

Yeah, I had numerous inquires and bugs come my way even after fixing vfb and vkb devid initialization in libxl with xen.git commit 5420f265. It took some time for the fix to make its way to downstream users. Since there is not yet a fix in Xen, it only makes sense to do the nic devid initialization in libvirt to fix PXE booting HVM domains. > The change here should accept any auto-assignment that makes it into > libxl_device_nic_init.

Otherwise, if intel_iommu=off, the ioctl returns 0, the function returns true, and we attempt to start a domain that is destined to fail. I've been doing a fair bit of testing of this series and with the exception of the above issue, haven't noticed any problems thus far. Unfortunately, you will need to rebase the series and post a v9, but I'm confident we can get this pushed after the 1.2.1 freeze. Thanks!

[libvirt] [PATCHv2] test driver: Add authentication to test driver.
by Richard W.M. Jones 08 Jan '14

08 Jan '14

There is no easy way to test authentication against libvirt. This commit modifies the test driver to allow simple username/password authentication. You modify the test XML by adding: <node> ... <auth> <user password="123456">rich</user> <user>jane</user> </auth> </node> If there are any /node/auth/user elements, then authentication is required by the test driver (if none are present, then the test driver will work as before and not require authentication). In the example above, two phony users are added: rich password: 123456 jane no password required The test driver will demand a username. If the password attribute is present (or if the username entered is wrong), then the password is also asked for and checked: $ virsh -c test://$(pwd)/testnode.xml list Enter username for localhost: rich Enter rich's password for localhost: *** Id Name State ---------------------------------------------------- 1 fv0 running 2 fc4 running Signed-off-by: Richard W.M.

[libvirt] [PATCH] event: clean up client side RPC code
by Eric Blake 08 Jan '14

08 Jan '14

Commit cfd62c1 was incomplete; I found more cases where error messages were being overwritten, and where the code between the three registration/deregistration APIs was not consistent. Since it is fairly easy to trigger an attempt to register an unregistered object, I also changed the error message from VIR_ERR_INTERNAL_ERROR to VIR_ERR_INVALID_ARG. * src/conf/object_event.c (virObjectEventCallbackListEventID): Inline... (virObjectEventStateEventID): ...into lone caller, and report error on failure. (virObjectEventCallbackListAddID, virObjectEventStateCallbackID) (virObjectEventCallbackListRemoveID) (virObjectEventCallbackListMarkDeleteID): Tweak error category. * src/remote/remote_driver.c (remoteConnectDomainEventRegister): Don't leak registration on failure. (remoteConnectDomainEventDeregisterAny) (remoteConnectNetworkEventDeregisterAny): Don't overwrite error.

[libvirt] [libvirt-java] [PATCH 0/3] Make the Java wrapper more fun to use
by Claudio Bley 08 Jan '14

08 Jan '14

This patchset first implements the ByteChannel interface for the Stream class which makes it readily usable with any standard Java library. Note, that this changes the wrapping of the virStreamRecv and virStreamSend function of the jna.Libvirt interface (which also makes this more efficient because a ByteBuffer is used instead of an Array). However, this interface should not be considered part of the public interface of the library, as with all classes part of the org.libvirt.jna package. In order to put this new functionality to use, the virDomainScreenshot function is wrapped and a unit test added to exercise it a bit.
