[libvirt] [PATCH v3 0/3] usb devices with same vendorID, productID hotplug support
by Guannan Ren 04 May '12

04 May '12

https://bugzilla.redhat.com/show_bug.cgi?id=815755 The set of patch tries to fix the issue when multiple usb devices with same idVendor, idProduct are availible on host, the usb device with lowest bus:device will be attached to guest if usb xml file is given like this: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x15e1'/> <product id='0x2007'/> </source> </hostdev> The reason is that the usb hotplug function searchs usb device in system files to match vendor and product id, the file with lowest number is always found first. After fix, in this case, libvirt will report an error like: # virsh attach-device rhel6u1 /tmp/usb.xml error: Failed to attach device from /tmp/usb.xml error: operation failed: multiple USB devices for 15e1:2007, use <address> to specify one At the same time, the usb part of domain initilization is also updated in patch 2/3 These patches also fix the problem when using the following xml, the usb device could be hotplugged in two domains without raising errors <hostdev mode='subsystem' type='usb' managed='yes'> <source> <address bus='6' device='7'/> </source> </hostdev> # virsh attach-device rhel6u12nd /tmp/usb_by_bus.xml error: Failed to attach device from /tmp/usb_by_bus.xml error: Requested operation is not valid: USB device 006:007 is in use by domain rhel6u1

[libvirt] [PATCH 2/2] Modify interface qemuDefaultScsiControllerModel().
by Li Zhang 04 May '12

04 May '12

Now, the libvirt sets the default module as 'ibmvscsi' for pseries, and 'lsi' for other platforms.The controller model should be set according to controller type, not only just the platform, otherwise, it will have to set controller's model externally to select right model for specific controller type. This patch is to modify the qemuDefaultScsiControllerModel() interface to set right controller model according to the controller's type. For pseries guest, PCI scsi controller is also supported. So the default scsi controller model is set according to the contrller type. If it is PCI scsi controller, the default model is set as lsi, and if it is VSCSI controller, the default model is set as ibmvscsi.

[libvirt] [PATCH 1/1] Support libnl-3 as well as libnl-1
by Serge Hallyn 04 May '12

04 May '12

configure.ac: Check for libnl-3. If found, find libnl-route-3. If not found, do the original check to look for libnl-1. src/util/virnetlink.c: support libnl3 api. I could play games to make the patch smaller, but this would just hide what is actually needing to be done at the expense of clarity. src/Makefile.am and daemon/Makefile.am: Add LIBNL_ROUTE3_{LIBS,CFLAGS} Unfortunately libnl3 moves netlink/msg.h to /usr/include/libnl3/netlink/msg.h, which is the reason why the LIBNL_CFLAGS need to be added to a bunch of places where they weren't needed with libnl1. Those spots probaby don't actually need to also have LIBNL*LIBS added, but while I may be looking at it wrong, it seemed right to do so. I haven't gotten as far as to compile this into a package on ubuntu, but the source does build with libnl-3 as well as with libnl-1.

[libvirt] [PATCH v6 0/9] Add basic driver for Parallels Virtuozzo Server
by Dmitry Guryanov 03 May '12

03 May '12

Parallels Virtuozzo Server is a cloud-ready virtualization solution that allows users to simultaneously run multiple virtual machines and containers on the same physical server. Current name of this product is Parallels Server Bare Metal and more information about it can be found here - http://www.parallels.com/products/server/baremetal/sp/. This driver will work with PVS version 6.0 , beta version scheduled at 2012 Q2. Dmitry Guryanov (9): pvs: add driver skeleton util: add functions for interating over json object pvs: add functions to list domains and get info pvs: implement functions for domain life cycle management pvs: get info about serial ports pvs: add support of VNC remote display pvs: implement virDomainDefineXML operation for existing domains pvs: add storage driver pvs: implement VM creation AUTHORS | 1 + cfg.mk | 1 + configure.ac | 23 + docs/drvpvs.html.in | 28 + include/libvirt/virterror.h | 1 + libvirt.spec.in | 7 + mingw32-libvirt.spec.in | 6 + po/POTFILES.in | 4 + src/Makefile.am | 23 + src/conf/domain_conf.c | 3 +- src/conf/domain_conf.h | 1 + src/driver.h | 1 + src/libvirt.c | 12 + src/pvs/pvs_driver.c | 1309 ++++++++++++++++++++++++++++++++++++++ src/pvs/pvs_driver.h | 75 +++ src/pvs/pvs_storage.c | 1458 +++++++++++++++++++++++++++++++++++++++++++ src/pvs/pvs_utils.c | 131 ++++ src/util/json.c | 30 + src/util/json.h | 4 + src/util/virterror.c | 3 + 20 files changed, 3120 insertions(+), 1 deletions(-) create mode 100644 docs/drvpvs.html.in create mode 100644 src/pvs/pvs_driver.c create mode 100644 src/pvs/pvs_driver.h create mode 100644 src/pvs/pvs_storage.c create mode 100644 src/pvs/pvs_utils.c

[libvirt] [PATCH] util: remove error log from stub versions of virNetlinkEventServiceStart|Stop
by Laine Stump 03 May '12

03 May '12

These two functions are called from main() on all platforms, and always return success on platforms that don't support libnl. They still log an error message, though, which doesn't make sense - they should just be NOPs on those platforms. --- src/util/virnetlink.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/src/util/virnetlink.c b/src/util/virnetlink.c index a249e94..34d56ef 100644 --- a/src/util/virnetlink.c +++ b/src/util/virnetlink.c @@ -615,7 +615,6 @@ int virNetlinkCommand(struct nl_msg *nl_msg ATTRIBUTE_UNUSED, */ int virNetlinkEventServiceStop(void) { - netlinkError(VIR_ERR_INTERNAL_ERROR, "%s", _(unsupported)); return 0; } @@ -625,7 +624,6 @@ int virNetlinkEventServiceStop(void) */ int virNetlinkEventServiceStart(void) { - netlinkError(VIR_ERR_INTERNAL_ERROR, "%s", _(unsupported)); return 0; } -- 1.7.10
