by Jim Fehlig 28 Aug '15

28 Aug '15

This reverts commit 1ce7c1d20cfd5afb26d2dbc88201085d52415d0e, which introduced a significant semantic change to the virDomainGetInfo() API. Additionally, the change was only made to 2 of the 15 virt drivers.

[libvirt] [PATCH] network type ethernet not needs to be reconnected
by Vasiliy Tolstov 28 Aug '15

28 Aug '15

libvirt docs says that network type ethernet not fully managed by libvirt, so don't check for ip. This fixes issue when no ip assigned to interface in libvirt domain xml and somebody want to change link state of interface.

[libvirt] Should external snapshots be possible with type volume image files?
by Stefan Bader 28 Aug '15

28 Aug '15

At least up to libvirt version 1.2.16 an external snapshot fails when the image file (supported type like QCOW2) is not specified as type='file' by as type='volume' to a pool that consists of image files (type directory). The reason there is that the source element of the disk definition does not contain the full path but only references to pool and volume name. Which would require an additional indirection in order to find that it actually is a file and what the path is. And that would make things more complicated. So my question is whether this should work and needs fixing in code or was never meant to be used that way. If the latter, then maybe needs a clarification in the documentation. At least the wiki did read for me as only requiring to be a image file of a supported type. And we got at least one bug report about it. Thanks, Stefan

[libvirt] [PATCH 0/9] qemu: assign addresses to USB devices
by Ján Tomko 28 Aug '15

28 Aug '15

For https://bugzilla.redhat.com/show_bug.cgi?id=1215968 For domains started without the addresses specified on the command line, QEMU makes up the addresses and adds USB hubs if the device is added to the second-to-last USB port. A domain started with these exact ports and hubs specified on the command line is not compatible with this domain. This series only generates the addresses for new domains, to avoid breaking migrating already existing domains. Ján Tomko (9): Remove dead code from qemuDomainAttachControllerDevice Remove unused virDomainVirtioSerialAddrSetRemoveController Store USB port path as an array of integers Add newDomain parameter to qemuDomainAssignAddresses Introduce virDomainUSBAddressSet Add functions for adding usb controllers to addrs Reserve existing USB addresses Assign addresses to USB devices Assign addresses on USB device hotplug src/conf/domain_addr.c | 406 +++++++++++++++++++-- src/conf/domain_addr.h | 53 ++- src/conf/domain_conf.c | 29 +- src/conf/domain_conf.h | 4 +- src/libvirt_private.syms | 10 +- src/qemu/qemu_command.c | 235 +++++++++++- src/qemu/qemu_command.h | 3 +- src/qemu/qemu_domain.h | 1 + src/qemu/qemu_driver.c | 22 +- src/qemu/qemu_hotplug.c | 57 ++- src/qemu/qemu_process.c | 6 +- tests/qemuhotplugtest.c | 2 +- ...qemuhotplug-console-compat-2+console-virtio.xml | 4 +- .../qemuhotplug-hotplug-base+disk-usb.xml | 1 + .../qemuxml2argvdata/qemuxml2argv-bios-nvram.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-bios.args | 2 +- .../qemuxml2argv-console-compat-2.xml | 4 +- .../qemuxml2argv-controller-order.args | 7 +- .../qemuxml2argv-controller-order.xml | 2 + .../qemuxml2argv-disk-usb-device-removable.args | 3 +- .../qemuxml2argv-disk-usb-device.args | 3 +- .../qemuxml2argv-graphics-spice-timeout.args | 2 +- ...muxml2argv-hostdev-usb-address-device-boot.args | 2 +- .../qemuxml2argv-hostdev-usb-address-device.args | 3 +- .../qemuxml2argv-hugepages-numa.args | 2 +- .../qemuxml2argv-input-usbmouse-addr.args | 2 +- .../qemuxml2argv-input-usbmouse-addr.xml | 2 +- .../qemuxml2argv-pseries-usb-kbd.args | 2 +- .../qemuxml2argv-serial-spiceport.args | 2 +- .../qemuxml2argv-smartcard-controller.args | 2 +- .../qemuxml2argv-smartcard-host-certificates.args | 2 +- .../qemuxml2argv-smartcard-host.args | 2 +- ...emuxml2argv-smartcard-passthrough-spicevmc.args | 3 +- .../qemuxml2argv-smartcard-passthrough-tcp.args | 2 +- .../qemuxml2argv-sound-device.args | 2 +- .../qemuxml2argv-usb-hub-conflict.xml | 22 ++ .../qemuxml2argv-usb-port-autoassign.args | 15 + .../qemuxml2argv-usb-port-autoassign.xml | 27 ++ tests/qemuxml2argvtest.c | 11 +- tests/qemuxmlnstest.c | 2 +- 40 files changed, 854 insertions(+), 109 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-hub-conflict.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-port-autoassign.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-port-autoassign.xml -- 2.4.6
