The libvirt build for mingw explicitly wants to avoid pthread_*, and use native threading instead (at least we wanted to explicitly avoid the old pthreads-w32, and since we already have native thread support, we might as well use it instead of dragging in winpthreads). Probably a case of our configure checks not detecting the right situation once winpthreads are turned on. I'll see if we can get this fixed up for libvirt 1.1.2 (due real soon now), or if it will have to wait for 1.1.3 (a month out, but probably still in time to make it into F20). Is there an easy environment to set up (such as rawhide + a repo) for testing a mingw cross-build with winpthreads? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

[libvirt] [PATCH] build: hoist system-specific checks before library checks
by Eric Blake 18 Sep '13

18 Sep '13

Commit f92c7e3 fixed a regression for native builds, but introduced a regression for cross-compilation builds; in particular, ./autobuild.sh on a Fedora system with mingw cross-compiler fails with: checking for qemu-kvm... /usr/bin/qemu-kvm checking for yajl_parse_complete in -lyajl... no checking for yajl_tree_parse in -lyajl... no configure: error: You must install the libyajl library & headers to compile libvirt Since we default $with_qemu to 'yes' rather than 'check', and then flip that default based on platform-specific checks, those platform specifics need to come prior to any library checks that depend on the value of $with_qemu. * configure.ac: Ensure system defaults are sane before checking for things that make decisions based on system default.

[libvirt] [PATCH] build: skip ld_preload tests on non-Linux systems
by Eric Blake 18 Sep '13

18 Sep '13

A cross build to mingw fails with: CC virsystemdtest-virsystemdtest.o ../../tests/virsystemdtest.c: In function 'testCreateNoSystemd': ../../tests/virsystemdtest.c:97:9: error: implicit declaration of function 'unsetenv' [-Werror=implicit-function-declaration] unsetenv("FAIL_NO_SERVICE"); ^ ../../tests/virsystemdtest.c:97:9: error: nested extern declaration of 'unsetenv' [-Werror=nested-externs] We could cop out and pull in the gnulib unsetenv module. But when you stop and think about it, this test requires LD_PRELOAD to work, and systemd is a Linux-only concept anyways, both of which mean the test could never work on mingw in the first place. Simpler is to just fix the test to behave like our other LD_PRELOAD tests. * tests/virsystemdtest.c: Provide non-Linux implementation.

The specifics of how that happens are left up to the bridge.) Yes, I think this the test that interests me. The key fact in my scenario is that I'm not preconfiguring a bridge. I wouldn't be able to set the forward mode as 'bridge' unless I already prepared a bridge. I recongize that if I prepared a bridge that I could add more portgroups to it with thier unique vlan tags and not expect anything to actually cross the physical interface. I think this is what is is reccomended among the blogs when one searches for "openvswitch fake bridge." > You'll need to post a copy of your network config for me to understand > for sure, but I'm guessing that you're missing one of the two items in > your config, possibly indicating that you've misunderstood how to > configure a libvirt network that uses an openvswitch bridge. > > So can you send a copy of your network XML? The network that I'm trying to define is described as the following. Note there there is no <forward> element as I'm not expcting there to be a *real* bridge and I don't expect that I need to preconfigre explicit bridges. I expect an ephemeral virtual bridge to be created. <network> <name>ajith-net1</name> <virtualport type='openvswitch'/> <portgroup name='client_lan'> <vlan> <tag id='1'/> </vlan> </portgroup> <portgroup name='client_wan'> <vlan> <tag id='2'/> </vlan> </portgroup> </network> When I include the VLAN tags I get the error: error: unsupported configuration: <vlan> element specified for network ajith-net1, whose type doesn't support vlan configuration When I omit the VLAN tags as follows I am able to create the network: <network> <name>ajith-net1</name> <virtualport type='openvswitch'/> <portgroup name='client_lan'> </portgroup> <portgroup name='client_wan'> </portgroup> </network> In my domain configs I specify the network like so: <interface type='network'> <source network='ajith-net1' portgroup='client_lan'/> <virtualport type='openvswitch'/> <model type='virtio'/> </interface> The resulting ephemeral bridge(virbr1) looks like the following when my network(w/o vlans) and two domains are started. I don't know if the portgroup was meaningful, but it was accepted in the definition: $ sudo ovs-vsctl show <...> Bridge "virbr1" Port "vnet23" Interface "vnet23" Port "vnet25" Interface "vnet25" Port "virbr1" Interface "virbr1" type: internal Port "virbr1-nic" Interface "virbr1-nic" ovs_version: "1.9.3" My goal is assign unique vlan tags to the two portgroups. While the network and the domains are started, I can manually add tags to the ports: $ sudo ovs-vsctl set port vnet25 tag=2 $ sudo ovs-vsctl set port vnet23 tag=1 $ sudo ovs-vsctl show Bridge "virbr1" Port "vnet23" tag: 1 Interface "vnet23" Port "vnet25" tag: 2 Interface "vnet25" Port "virbr1" Interface "virbr1" type: internal Port "virbr1-nic" Interface "virbr1-nic" ovs_version: "1.9.3" This configuration behaves exactly as I want. I'm interested to learn how to prepare this without the manual step of tagging the ports outside of the libvirt operations. Ultimately my goal is to prepare isolated test environments that consist of several VM's attached to a similar qty of vlans. I intend to create many of these environments per host. I also recongnize that instead of portgroups, I could use separate networks altogether. From an administrative standpoint, I'd prefer to have one "network" per test environment, with several portgroups, instead of *many* networks. FWIW, I'm doing something similar on ESX, where I create a "vSwitch" and then create several "portgroups", each with its own vlan tag. These vSwitches are not attached to any physical interfaces. (My esx work is directly against the vsphere API, so I'm not sure if the same could be configured via libvirt) I'm looking to port this work to KVM. It seems like a pretty natural thing to support.

[libvirt] [PATCH 1/2] blkiotune: add support for device iops and bps throttle

18 Sep '13

From: Guan Qiang <hzguanqiang(a)corp.netease.com> This adds per-device iops and bps throttle to <blkiotune>. By extending the existed 'domainSetBlkioParameters' interface, read/write iops and bps throttle for per-device can be set with blkio cgroup. The blkiotune xml entry is now looked like: <domain ...> <blkiotune> <device> <path>/path/to/block</path> <weight>1000</weight> <read_bps>100000</read_bps> <write_bps>100000</write_bps> <read_iops>100000</read_iops> <write_iops>1000000</write_iops> </device> </blkiotune> .. Elments <weight>,<read_bps>,<write_bps>,<read_iops>,<write_iops> are all optional, but must have one. --- docs/formatdomain.html.in | 8 + docs/schemas/domaincommon.rng | 28 +- include/libvirt/libvirt.h.in | 40 ++ src/conf/domain_conf.c | 115 +++- src/conf/domain_conf.h | 16 +- src/libvirt_private.syms | 4 +- src/lxc/lxc_cgroup.c | 9 +- src/qemu/qemu_cgroup.c | 10 +- src/qemu/qemu_driver.c | 579 ++++++++++++++++++-- src/util/vircgroup.c | 79 ++- src/util/vircgroup.h | 8 +- .../qemuxml2argv-blkiotune-device.xml | 4 + 12 files changed, 789 insertions(+), 111 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index a927643..daf4f7a 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -753,10 +753,18 @@ <device> <path>/dev/sda</path> <weight>1000</weight> + <read_bps>20000000</read_bps> + <write_bps>30000000</write_bps> + <read_iops>4000</read_iops> + <write_iops>5000</write_iops> </device> <device> <path>/dev/sdb</path> <weight>500</weight> + <read_bps>30000000</read_bps> + <write_bps>30000000</write_bps> + <read_iops>4300</read_iops> + <write_iops>6000</write_iops> </device> </blkiotune> ... diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index 4d333a8..10553af 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -621,9 +621,31 @@ <element name="path"> <ref name="absFilePath"/> </element> - <element name="weight"> - <ref name="weight"/> - </element> + <optional> + <element name="weight"> + <ref name="weight"/> + </element> + </optional> + <optional> + <element name="read_bps"> + <data type="unsignedLong"/> + </element> + </optional> + <optional> + <element name="write_bps"> + <data type="unsignedLong"/> + </element> + </optional> + <optional> + <element name="read_iops"> + <data type="unsignedLong"/> + </element> + </optional> + <optional> + <element name="write_iops"> + <data type="unsignedLong"/> + </element> + </optional> </interleave> </element> </zeroOrMore> diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index a47e33c..fd4a2e5 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -1780,6 +1780,46 @@ char * virDomainGetSchedulerType(virDomainPtr domain, #define VIR_DOMAIN_BLKIO_DEVICE_WEIGHT "device_weight" +/** + * VIR_DOMAIN_BLKIO_THROTTLE_DEVICE_READ_BPS: + * + * Macro for the BLKIO tunable throttle.read_bps_device: it represents the read + * bytes per second permitted through a block device, as a string. + * The string is parsed as a series of /path/to/device,read_bps elements, + * separated by ',', with element read_bps as a ullong. + */ +#define VIR_DOMAIN_BLKIO_THROTTLE_DEVICE_READ_BPS "device_read_bps" + +/** + * VIR_DOMAIN_BLKIO_THROTTLE_DEVICE_WRITE_BPS: + * + * Macro for the BLKIO tunable throttle.write_bps_device: it represents the write + * bytes per second permitted through a block device, as a string. + * The string is parsed as a series of /path/to/device,write_bps elements, + * separated by ',', with element write_bps as a ullong. + */ +#define VIR_DOMAIN_BLKIO_THROTTLE_DEVICE_WRITE_BPS "device_write_bps" + +/** + * VIR_DOMAIN_BLKIO_THROTTLE_DEVICE_READ_IOPS: + * + * Macro for the BLKIO tunable throttle.read_iops_device: it represents the read + * I/O operations per second permitted through a block device, as a string. + * The string is parsed as a series of /path/to/device,read_iops elements, + * separated by ',', with element read_iops as a ullong. + */ +#define VIR_DOMAIN_BLKIO_THROTTLE_DEVICE_READ_IOPS "device_read_iops" + +/** + * VIR_DOMAIN_BLKIO_THROTTLE_DEVICE_WRITE_IOPS: + * + * Macro for the BLKIO tunable throttle.write_iops_device: it represents the write + * I/O operations per second permitted through a block device, as a string. + * The string is parsed as a series of /path/to/device,write_iops elements, + * separated by ',', with element write_iops as a ullong. + */ +#define VIR_DOMAIN_BLKIO_THROTTLE_DEVICE_WRITE_IOPS "device_write_iops" + /* Set Blkio tunables for the domain*/ int virDomainSetBlkioParameters(virDomainPtr domain, virTypedParameterPtr params, diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 05c1de4..f9df10f 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -880,47 +880,100 @@ virDomainXMLOptionGetNamespace(virDomainXMLOptionPtr xmlopt) void -virBlkioDeviceWeightArrayClear(virBlkioDeviceWeightPtr deviceWeights, +virBlkioDeviceIoTuneInfoArrayClear(virBlkioDeviceIoTuneInfoPtr devices, int ndevices) { size_t i;
