[libvirt] [PATCH v2 0/6]qemu: add usb-bot scsi controller support
by Guannan Ren 17 Sep '13

17 Sep '13

BZ:https://bugzilla.redhat.com/show_bug.cgi?id=917702 v2: After discussion in BZ, qemu guys hope the usb-bot(+usb-uas) can be supported although the absence of its hot-plug feature. In this patch, libvirt gives an unsupported error in this case. v1: https://www.redhat.com/archives/libvir-list/2013-September/msg00020.html And as the missing of hot-plug feature, the replacement of usb-storage is not a urgent thing. disk attached to usb-storage supports hot-plug/unplug already.

[libvirt] Release of libvirt-java-0.5.0
by Daniel Veillard 17 Sep '13

17 Sep '13

With a bit of delay, the release needed by Wido is finally available, it is tagged in git and I have pushed tarball, jar and rpms to the FTP: ftp://libvirt.org/libvirt/java/ Wido maybe you can push to Maven, I'm unsure how to do this and last time I tried I made a mess :-) I bumped the intermediate release number as this release includes more improvements and fixes than the previous ones and deprecates a couple of things: Portability: - Fix the rpm build (Daniel Veillard) - Explicitly set includeAntRuntime to false for javac tasks. (Claudio Bley) - Fix build with jna >= 3.5.0 (Jiri Denemark) Bug Fixes: - Fixed broken dates in Changelog (Daniel Veillard) - Fix memory leaks for libvirt functions returning newly allocated memory. (Claudio Bley) - Fix memory leak for virDomainGetSchedulerType. (Claudio Bley) Improvements: - Implement and use virDomainMigrateToURI2 by overloading migrateToUri (Wido den Hollander) - Implement virDomainMigrate2 and use it for a new migrate method. (Wido den Hollander) - Overload Domain.snapshotCreateXML with a method that has an argument for flags (Wido den Hollander) - Overload Domain.snapshotListNames with a method that has an additional flags argument. (Wido den Hollander) - Implement virDomainUndefineFlags by overloading the existing undefine method (Wido den Hollander) - Implement virStorageVolResize by adding resize to StorageVol (Wido den Hollander) - Implement virDomainBlockResize (Wido den Hollander) - Avoid creating new Arrays and Lists on every struct instantiation (Claudio Bley) - Make the build fail if any of the JUnit tests have errors or failures (Claudio Bley) - Avoid unnecessary copying and calling virResetLastError. (Claudio Bley) - Split "build" target and automatically rebuild out of date files. (Claudio Bley) - Split JUnit tests and use a fixture for Connect. (Claudio Bley) - Call processError only if a libvirt function indicates an error. (Claudio Bley) - Change visibility of class members to private to enforce encapsulation. (Claudio Bley) - Make finalize() methods protected. (Claudio Bley) - Add findbugs build file for ant. (Claudio Bley) - Introduce a javac.debug property. (Claudio Bley) - maint: correct name for license file (Eric Blake) - Add Javadoc and Source JARs to Maven repo (Wido den Hollander) - Fix the Maven build system with Ant (Wido den Hollander) Cleanups: - trivial remove unused imports (Stefan Majer) - Remove unused imports (Stefan Majer) - Remove functions not intended to be used by libvirt bindings. (Claudio Bley) - Remove the libvirt instance attribute from all classes. (Claudio Bley) - Mark virConnCopyLastError and virConnGetLastError as deprecated. (Claudio Bley) - Remove redundant public modifier from Libvirt interface methods. (Claudio Bley) Thanks Claudio, Wido and everybody else who contributed !

[libvirt] [bug] State of "in shutdown".
by Dongsheng Yang 17 Sep '13

17 Sep '13

Hi experts: I got the following description by <man virsh>: ``` STATES shutdown The domain is in the process of shutting down, i.e. the guest operating system has been notified and should be in the process of stopping its operations gracefully. ``` But I found the state of VM is "running" even when it is in process of shutting down. e.g: # virsh list Id Name State ---------------------------------------------------- 41 virt-tests-vm1 running # virsh shutdown virt-tests-vm1;echo $?;virsh domstate virt-tests-vm1 --reason Domain virt-tests-vm1 is being shutdown 0 running (booted) # virsh domstate virt-tests-vm1 --reason running (booted) ... ... # virsh domstate virt-tests-vm1 --reason shut off (shutdown) As shown above, I can not get a "shutdown" (or "in shutdown") for the VM state. Do you think it is a bug, or something not good enough? Wish your help!!

[libvirt] [PATCHv4 0/4] VMX: CD-ROM handling improvements
by Doug Goldstein 17 Sep '13

17 Sep '13

A user came into #virt the other day and was trying to get libvirtd to work with VMware Fusion 5, which is basically the Mac OS X version of VMware Workstation. In helping him out I noticed a few limitations of our VMX parser so I've added support through this patchset. I don't personally have access or own VMware's product. v4: * Half the patchset has been merged at this point * Add back 'auto detect' support via <source startupPolicy='optional'/> * Made device='lun' match device='cdrom' * Patch 1 & 2 are new to the series v3: * Dropped 'auto detect' support from series as it needs more work based on feedback * Added patch to combine virVMXFormatHardDisk and virVMXFormatCDROM into one function. * Converted to <disk type='block' device='lun'> instead of adding a <driver> element to better match the behavior available via QEMU. v2: * Added additional test cases and fixed issues that arose from those *** BLURB HERE *** Doug Goldstein (4): Allow LUN type disks to have no source Allow <source> for type=block to have no dev VMX: Add support for 'auto detect' fileNames VMX: Add a VMWare Fusion 5 configuration for tests docs/schemas/domaincommon.rng | 8 +- src/conf/domain_conf.c | 9 ++- src/vmx/vmx.c | 28 +++++-- .../vmx2xml-cdrom-ide-raw-auto-detect.vmx | 5 ++ .../vmx2xml-cdrom-ide-raw-auto-detect.xml | 24 ++++++ .../vmx2xml-cdrom-scsi-raw-auto-detect.vmx | 6 ++ .../vmx2xml-cdrom-scsi-raw-auto-detect.xml | 24 ++++++ tests/vmx2xmldata/vmx2xml-fusion-in-the-wild-1.vmx | 88 ++++++++++++++++++++++ tests/vmx2xmldata/vmx2xml-fusion-in-the-wild-1.xml | 39 ++++++++++ tests/vmx2xmltest.c | 4 + .../xml2vmx-cdrom-ide-raw-auto-detect.vmx | 14 ++++ .../xml2vmx-cdrom-ide-raw-auto-detect.xml | 14 ++++ .../xml2vmx-cdrom-scsi-raw-auto-detect.vmx | 15 ++++ .../xml2vmx-cdrom-scsi-raw-auto-detect.xml | 14 ++++ tests/xml2vmxdata/xml2vmx-fusion-in-the-wild-1.vmx | 30 ++++++++ tests/xml2vmxdata/xml2vmx-fusion-in-the-wild-1.xml | 41 ++++++++++ tests/xml2vmxtest.c | 4 + 17 files changed, 356 insertions(+), 11 deletions(-) create mode 100644 tests/vmx2xmldata/vmx2xml-cdrom-ide-raw-auto-detect.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-cdrom-ide-raw-auto-detect.xml create mode 100644 tests/vmx2xmldata/vmx2xml-cdrom-scsi-raw-auto-detect.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-cdrom-scsi-raw-auto-detect.xml create mode 100644 tests/vmx2xmldata/vmx2xml-fusion-in-the-wild-1.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-fusion-in-the-wild-1.xml create mode 100644 tests/xml2vmxdata/xml2vmx-cdrom-ide-raw-auto-detect.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-cdrom-ide-raw-auto-detect.xml create mode 100644 tests/xml2vmxdata/xml2vmx-cdrom-scsi-raw-auto-detect.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-cdrom-scsi-raw-auto-detect.xml create mode 100644 tests/xml2vmxdata/xml2vmx-fusion-in-the-wild-1.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-fusion-in-the-wild-1.xml -- 1.8.1.5

[libvirt] [PATCHv3 0/4] Introduce APIs to extract DHCP leases info
by Nehal J Wani 17 Sep '13

17 Sep '13

This API returns the leases information stored in the DHCP leases file of dnsmasq for a given virtual network. It contacts the bridge network driver, which parses the leases file. It supports two methods: 1. Return info for all network interfaces connected to a given virtual network 2. Return information for a particular network interface in a given virtual network by providing its MAC Address v3 * Mostly small nits, change in MACRO names, use of virSocketAddrGetIpPrefix to retrieve IP prefix from @dom XML. v2 * Since DHCPv6 is supposed to be suported in future, virNetworkGetDHCPLeasesForMAC changed, prefix and virIPAddrType added in virNetworkDHCPLeases struct. Refer: https://www.redhat.com/archives/libvir-list/2013-September/msg00732.html v1 * Refer: https://www.redhat.com/archives/libvir-list/2013-September/msg00620.html * The need for these APIs were result of a RFC was proposed on the list.

[libvirt] [PATCHv2] build: make autobuild require rpm build deps
by Eric Blake 17 Sep '13

17 Sep '13

I spent far too long on a new machine trying to figure out why ./autobuild.sh failed due to an rpm build failure (complaining that libvirt_parthelper was supposed to be packaged but was not built), and finally traced it to a missing parted-devel installation. I learned that --nodeps is in place for autobuilder setups, but for developers, removing it would make rpmbuild error out much sooner for a less cryptic failure. * autobuild.sh: Conditionally drop --nodeps from rpmbuild lines.
