[libvirt] [PATCH] libxl: include a XLU_Config in _libxlDriverConfig
by Olaf Hering 07 May '15

07 May '15

Upcoming changes for vscsi will use libxlutil.so to prepare the configuration for libxl. The helpers needs a xlu struct for logging. Provide one and reuse the existing output as log target.

[libvirt] [PATCH] lxc: don't up the veth interfaces unless explicitly asked to
by Lubomir Rintel 06 May '15

06 May '15

Upping an interface for no reason and not configuring it is a cardinal sin. With the default addrgenmode if eui64 it sticks a link-local address to the interface. That is not good, as NetworkManager would see an address configured, assume the interface is already configured and won't touch it iself and the interface might stay unconfigured until the end of the days.

[libvirt] [PATCH] virsh: fix no error output when parse cpulist fail
by Luyao Huang 06 May '15

06 May '15

When we pass a invalid cpulist or the lastcpu in the cpulist exceed the maxcpu, we cannot get any error. like this: # virsh vcpupin test3 1 aaa # virsh vcpupin test3 1 1000 Because virBitmapParse() use virReportError() to set the error message, virsh client use vshError to output error. If we want get the error which set by virReportError(), we need virGetLastError/virGetLastErrorMessage to help us. However instead of do this, i chose use vshError to output error when parse failed.

I have CCed Eric Blake and the libvirt mailing list. This is a good time to discuss libvirt requirements for backup APIs. Current work for QEMU 2.4: * QMP command to take incremental backup of guest disks in a single atomic operation * Dirty bitmap persistence across live migration and QEMU restart Eric: Do you have any opinion on a differential backup feature in addition to incremental backup. My thoughts are that QEMU should only copy out changed blocks and let the backup application worry about concepts like incremental vs differential. From a host performance perspective, copying out the same blocks that have already been sent in a previous backup is a waste of I/O bandwidth. Even backup applications that want differential backup may not actually use the QEMU feature for this reason. Regarding the size of the patch, there's a cost to adding the tests, documentation, and commiting to QMP APIs. These costs dwarf the small code change that preserves the dirty bitmap. If there's a concrete requirement for this feature then I'm happy with it, but let's not add bells and whistles just because we can. Stefan

[libvirt] [PATCH] test: remove s390 tests used only for testing usb and ide controllers
by Laine Stump 05 May '15

05 May '15

Back in 2013, commit 877bc089 added in some tests that made sure no error was generated on a domain definition that had an automatically added usb controller if that domain didn't have a PCI bus to attach the usb controller to. In particular, two s390-specific tests were added, one with <controller type='usb' model='none'/> and another (called "s390-piix-controllers") that had both usb and ide controllers, but nothing attached to them. Then in February of this year, commit 09ab9dcc eliminated the annoying auto-adding of a usb device for s390 and s390x machines, stating: "Since s390 does not support usb the default creation of a usb controller for a domain should not occur." Since s390 doesn't support usb and usb controllers aren't added to s390 domain definitions automatically, there is no reason to have the tests with a usb controller and expect them to succeed. And since the only reference of an IDE controller wrt s390 that I've found is in the one test case mentioned above, and the commit log that added it specifically mentions the purpose to be quieting error messages on machines with no PCI bus, I'm assuming that the s390 also doesn't support IDE controllers. Based on that reasoning (and the fact that s390-piix-controllers causes a test error for an upcoming patch), this patch removes those two tests. --- .../qemuxml2argv-s390-piix-controllers.args | 12 -------- .../qemuxml2argv-s390-piix-controllers.xml | 34 ---------------------- .../qemuxml2argv-s390-usb-none.args | 12 -------- .../qemuxml2argv-s390-usb-none.xml | 29 ------------------ tests/qemuxml2argvtest.c | 10 ------- 5 files changed, 97 deletions(-) delete mode 100644 tests/qemuxml2argvdata/qemuxml2argv-s390-piix-controllers.args delete mode 100644 tests/qemuxml2argvdata/qemuxml2argv-s390-piix-controllers.xml delete mode 100644 tests/qemuxml2argvdata/qemuxml2argv-s390-usb-none.args delete mode 100644 tests/qemuxml2argvdata/qemuxml2argv-s390-usb-none.xml diff --git a/tests/qemuxml2argvdata/qemuxml2argv-s390-piix-controllers.args b/tests/qemuxml2argvdata/qemuxml2argv-s390-piix-controllers.args deleted file mode 100644 index e939be4..0000000 --- a/tests/qemuxml2argvdata/qemuxml2argv-s390-piix-controllers.args +++ /dev/null @@ -1,12 +0,0 @@ -LC_ALL=C PATH=/bin HOME=/home/test USER=test LOGNAME=test QEMU_AUDIO_DRV=none \ -/usr/bin/qemu-system-s390x -S -M s390-virtio -m 214 -smp 1 -nographic \ --nodefconfig -nodefaults \ --chardev socket,id=charmonitor,path=/tmp/test-monitor,server,nowait \ --mon chardev=charmonitor,id=monitor,mode=readline -no-acpi \ --device virtio-serial-s390,id=virtio-serial0 -drive \ -file=/dev/HostVG/QEMUGuest1,if=none,id=drive-virtio-disk0 \ --device virtio-blk-s390,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 \ --chardev pty,id=charconsole0 \ --device virtconsole,chardev=charconsole0,id=console0 \ --object rng-random,id=objrng0,filename=/dev/hwrng \ --device virtio-rng-s390,rng=objrng0,id=rng0 diff --git a/tests/qemuxml2argvdata/qemuxml2argv-s390-piix-controllers.xml b/tests/qemuxml2argvdata/qemuxml2argv-s390-piix-controllers.xml deleted file mode 100644 index a8b72d7..0000000 --- a/tests/qemuxml2argvdata/qemuxml2argv-s390-piix-controllers.xml +++ /dev/null @@ -1,34 +0,0 @@ -<domain type='qemu'> -
