Hi, I have sent those patches before 0.12, and updated them according to comments (hopefully you don't mind I send them all revised in the same thread) They bring: - domain audio <codec> selection, for ICH6 devices - domain port <forward>, for user-mode networking - storage <preallocation> mode for QCOW2 images Marc-André Lureau (9): qemu: test CAPS_HDA_MICRO domain: add <codec> sound sub-element qemu: honour sound <codec> sub-elements tests: add qemu-1.1-rc0 data tests: add ich6 codec type test to qemuxml2argv-sound-device storage: add preallocation element storage: learn to create qcow2 with preallocation domain: add <forward> element for user mode networking qemu: implement user mode port <forward> docs/formatdomain.html.in | 40 +++ docs/formatstorage.html.in | 6 + docs/schemas/domaincommon.rng | 58 +++- docs/schemas/storagevol.rng | 18 ++ src/conf/domain_conf.c | 286 +++++++++++++++++++- src/conf/domain_conf.h | 45 +++ src/conf/storage_conf.c | 26 ++ src/conf/storage_conf.h | 1 + src/libvirt_private.syms | 3 + src/qemu/qemu_capabilities.c | 3 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 213 +++++++++++++-- src/storage/storage_backend.c | 70 ++++- src/util/storage_file.c | 4 + src/util/storage_file.h | 10 + tests/qemuhelpdata/qemu-1.1 | 266 ++++++++++++++++++ tests/qemuhelpdata/qemu-1.1-device | 95 +++++++ tests/qemuhelptest.c | 70 +++++ tests/qemuxml2argvdata/qemuxml2argv-net-user.args | 5 +- tests/qemuxml2argvdata/qemuxml2argv-net-user.xml | 2 + .../qemuxml2argv-sound-device.args | 7 +- .../qemuxml2argvdata/qemuxml2argv-sound-device.xml | 7 + tests/qemuxml2argvtest.c | 3 +- tests/qemuxml2xmltest.c | 1 + tests/storagevolxml2xmlin/vol-qcow2.xml | 1 + tests/storagevolxml2xmlout/vol-qcow2.xml | 1 + 26 files changed, 1201 insertions(+), 41 deletions(-) create mode 100644 tests/qemuhelpdata/qemu-1.1 create mode 100644 tests/qemuhelpdata/qemu-1.1-device -- 1.7.10.1

[libvirt] [PATCH 0/2] qemu: Add support for -no-user-config
by Jiri Denemark 15 May '12

15 May '12

Eduardo submitted patches[1] for qemu implementing -no-user-config as a better alternative to all-or-nothing -nodefconfig. With this new option, we are finally able to use modern CPU models defined in qemu's configuration file without allowing user-supplied qemu configuration to mess up with qemu processes started by libvirt. The qemu patches are not committed upstream yet (and this patchset won't be committed either until qemu support is finished) but they are very close and are expected to make it into qemu-1.1.

[libvirt] [PATCH libvirt 0/5] Add ich6 <codec> sub-element
by Marc-André Lureau 15 May '12

15 May '12

Hi, Upcoming qemu 1.1 will have hda-micro codec device type, which helps to solve recording with some applications under Windows 7. The following series allows to specify the codecs attached to a ICH6 audio device, using the syntax described in commit comment 6cabc0b0d0fbc35a68bf1c0646898ac148d2fa3f: <sound model='ich6'> <codec type='micro'/> </sound> The codec type 'micro' maps to qemu 'hda-micro' device kind.

[libvirt] The config of IP address for 'macvtap' network
by Lei Li 15 May '12

15 May '12

Hi guys, I know the macvtap network is supported by libvirt as forward mode 'passthrough', I wonder is there anyway to configure the IP address for its interface? For example, If I create a network as below: <network> <name>vdsm-testnet</name> <uuid>31f6b3b3-e959-0dd1-ad3a-bf95db660415</uuid> <forward dev='eth0.8' mode='passthrough'> <interface dev='eth0.8'/> </forward> </network> For now, I have to set the IP address by 'ifconfig eth0.8 XXX.XXX.XXX.XXX' after defining the network. How can I set IP address for this VLAN device 'eth0.8' by libvirt, I mean does libvirt support to assign IP address in this mode now? If does, what is the xml format for it? It'd appreciate a lot if anybody could read my post and give me some suggestions! -- Lei
