[libvirt] [PATCH 00/10] Convert secret driver to use hashed object
by John Ferlan 19 Apr '16

19 Apr '16

This series replaces the usage of linked list in secret driver with a hashed object list as was suggested in the review in the last patch of the previous secret driver changes series: http://www.redhat.com/archives/libvir-list/2016-February/msg01274.html Patch 1 - starts the ball rolling Patch 2 - is yet another code optimization (as found in bridge_driver) Patches 3-8 - Add the new API's "slowly" (for review purposes) Patch 9 - replaces the usage of linked lists with the hashed object Patch 10 - moves the secretLoadAllConfigs to secret_conf The changes are loosely modeled after both virdomainobj and network_conf functionality. The real meat and potato(e)s is found in patches 5 and 9. Other functions should be relatively straightforward. I've done testing of various virsh secret-* commands (both valid and invalid options) as well as performing driver start, stop, and reload testing. Each patch was built using 'check' and 'syntax-check'. The end result is much more code in secret_conf and much less in secret_driver.

[libvirt] [PATCH v4 0/2] persistent live migration with specified XML
by Dmitry Andreev 18 Apr '16

18 Apr '16

v4: wrong param name in commit msg v3: - use shorter name for param and rename args - move qemuMigrationCookieAddPersistent out from qemuMigrationBakeCookie - rebase to master v2: reimplemented with new migration param Libvirt doesn't allow to specify destination persistent domain configuration.

[libvirt] [PATCH] ZFS: Support sparse volumes
by Richard Laager 17 Apr '16

17 Apr '16

By default, `zfs create -V ...` reserves space for the entire volsize, plus some extra (which attempts to account for overhead). If `zfs create -s -V ...` is used instead, zvols are (fully) sparse. A middle ground (partial allocation) can be achieved with `zfs create -s -o refreservation=... -V ...`. Both libvirt and ZFS support this approach, so the ZFS storage backend should support it.

14 Apr '16

Upcoming compression options for migration command patch series hits current limit of 32 possible options for a command. Lets take one step further and support 64 possible options. And all it takes is moving from 32 bit integers to 64 bit ones. The only less then trivial change i found is moving from 'ffs' to 'ffsl'.

[libvirt] [libxl] shutdown a domain before it finishes starting
by Zhangbo (Oscar) 13 Apr '16

13 Apr '16

Hi all: Suppose we have a guest domain which is pvops, for example, rhel6.4. Steps to produce the problem: 1 start the guest by virDomainCreate() 2 the API returns before the guest domain fully available, which means, the disks, network interfaces and some import services are not available inside the guest. 3 we call virDomainShutdown() to shutdown the guest. Expected result: The guest got shutdown. The result in fact: Because the guest is not available when we call virDomainShutdown(), it couldn't respond to our 'shutdown' xenstore request, the guest turns on later, rather than shutting down. So , the question is: In libxl_driver( xen-hypervisor environment), how can we tell that the guest is available or not, and is it suitable to shutdown the guest at that moment? Thanks in advance. Oscar.

[libvirt] [PATCH] qemuxml2argvtest: Adapt to ethernet automatic tap creation
by Michal Privoznik 13 Apr '16

13 Apr '16

After 9c17d665fdc5 the tap device for ethernet network type is automatically precreated before spawning qemu. Problem is, the qemuxml2argvtest wasn't updated and thus is failing. Because of all the APIs that new code is calling, I had to mock a lot. Also, since the tap FDs are labeled separately from the rest of the devices/files I had to enable NOP security driver for the test too. Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- There are only 2 problems with this patch. All of them are in virNetDevTapCreate mock implementation: 1) new tap device has constant name. Even within one domain 2) new tap FDs are constant. Even within one domain I'm unable to come with better approach though. Having a static variable that is incremented each time the mock is called would not fly as it will give different results when combined with VIR_TEST_RANGE. Therefore I assume we are good so far with these two limitations. cfg.mk | 2 +- tests/qemuhotplugtest.c | 7 ---- .../qemuxml2argv-graphics-spice-timeout.args | 2 +- .../qemuxml2argv-net-eth-ifname.args | 2 +- .../qemuxml2argv-net-eth-names.args | 4 +- tests/qemuxml2argvdata/qemuxml2argv-net-eth.args | 2 +- tests/qemuxml2argvmock.c | 49 ++++++++++++++++++++-- tests/testutilsqemu.c | 9 ++++ 8 files changed, 61 insertions(+), 16 deletions(-) diff --git a/cfg.mk b/cfg.mk index 6f28eef..f5573db 100644 --- a/cfg.mk +++ b/cfg.mk @@ -1139,7 +1139,7 @@ exclude_file_name_regexp--sc_copyright_usage = \ ^COPYING(|\.LESSER)$$ exclude_file_name_regexp--sc_flags_usage = \ - ^(docs/|src/util/virnetdevtap\.c$$|tests/(vir(cgroup|pci|usb)|nss)mock\.c$$) + ^(docs/|src/util/virnetdevtap\.c$$|tests/(vir(cgroup|pci|usb)|nss|qemuxml2argv)mock\.c$$) exclude_file_name_regexp--sc_libvirt_unmarked_diagnostics = \ ^(src/rpc/gendispatch\.pl$$|tests/) diff --git a/tests/qemuhotplugtest.c b/tests/qemuhotplugtest.c index 2298a68..1eb2b6a 100644 --- a/tests/qemuhotplugtest.c +++ b/tests/qemuhotplugtest.c @@ -341,7 +341,6 @@ mymain(void) { int ret = 0;

[libvirt] [PATCH 00/15] support for pxb and pxb-pcie controllers
by Laine Stump 12 Apr '16

12 Apr '16

These two controllers are used to create a new root bus on a 440fx (pxb) or q35 (pxb-pie) virtual machine. There may be other use cases, but the main reason for me taking the time to support a separate root bus is to have assigned devices be visible in the guest on a different NUMA node, so that the guest can be aware of the locality of the device wrt CPU and memory that are on different NUMA nodes - although you aren't required to, you can add a <node>N</node> subelement to the bus' <target> element to indicate which NUMA node it is on (it's up to the management application to place devices on that bus that really are on the given NUMA node in the host). There are several differences between pxb and pxb-pcie, which are detailed in the individual commit log messages, but in short: 1) pxb is for 440fx, pxb-pcie for q35 (they *might* work on other arches/machinetypes that have a PCI or PCIe bus, but I haven't enabled that) 2) pxb has an integrate d pci-bridge with 32 slots that are (should be) hotplug-capable, while pxb-pcie supplies only a single slot, and it will only accept a pcie-root-port (which will then accept a single device, hotplug-capable) or a pcie-switch-upstream-port. Along the way I encountered a few minor problems/ugliness that I took care of in patches 01/15 - 09/15. pxb support is in 10-12, and pxb-pcie is in 13-15 There is a bugzilla record associated with this: https://bugzilla.redhat.com/show_bug.cgi?id=1103314 Laine Stump (15): schema: make pci slot and function optional schema: rename uint8range/uint24range to uint8/uint24 schema: new basic type - uint16 schema: allow pci address attributes to be in decimal conf: use #define instead of literal for highest slot in upstream port conf: allow use of slot 0 in a dmi-to-pci-bridge conf/qemu: change the way VIR_PCI_CONNECT_TYPE_* flags work conf: utility function to convert PCI controller model into connect type qemu: set PCI controller default modelName in a separate function qemu: add capabilities bit for device "pxb" conf: new pci controller model pci-expander-bus qemu: support new pci controller model "pci-expander-bus" qemu: add capabilities bit for device "pxb-pcie" conf: new pci controller model pcie-expander-bus qemu: support new pci controller model "pcie-expander-bus" docs/formatdomain.html.in | 74 +++- docs/schemas/basictypes.rng | 63 ++-- docs/schemas/domaincommon.rng | 23 +- docs/schemas/networkcommon.rng | 12 +- docs/schemas/nwfilter.rng | 16 +- src/bhyve/bhyve_device.c | 10 +- src/conf/domain_addr.c | 119 +++++-- src/conf/domain_addr.h | 68 ++-- src/conf/domain_conf.c | 61 +++- src/conf/domain_conf.h | 11 +- src/libvirt_private.syms | 1 + src/qemu/qemu_capabilities.c | 4 + src/qemu/qemu_capabilities.h | 2 + src/qemu/qemu_command.c | 74 ++++ src/qemu/qemu_domain.c | 42 +++ src/qemu/qemu_domain_address.c | 305 +++++++++------- tests/qemucapabilitiesdata/caps_2.4.0-1.caps | 1 + tests/qemucapabilitiesdata/caps_2.5.0-1.caps | 1 + tests/qemucapabilitiesdata/caps_2.6.0-1.caps | 2 + tests/qemucapabilitiesdata/caps_2.6.0-1.replies | 3 + .../qemuxml2argv-aarch64-virtio-pci-default.args | 2 +- ...l2argv-aarch64-virtio-pci-manual-addresses.args | 2 +- .../qemuxml2argv-pci-expander-bus-bad-machine.xml | 167 +++++++++ .../qemuxml2argv-pci-expander-bus-bad-node.xml | 160 +++++++++ .../qemuxml2argv-pci-expander-bus.args | 87 +++++ .../qemuxml2argv-pci-expander-bus.xml | 167 +++++++++ .../qemuxml2argv-pcie-expander-bus-bad-machine.xml | 36 ++ .../qemuxml2argv-pcie-expander-bus.args | 123 +++++++ .../qemuxml2argv-pcie-expander-bus.xml | 247 +++++++++++++ .../qemuxml2argv-pcie-root-port.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-pcie-root.args | 2 +- .../qemuxml2argv-pcie-switch-downstream-port.args | 2 +- .../qemuxml2argv-pcie-switch-upstream-port.args | 2 +- .../qemuxml2argv-pcihole64-q35.args | 2 +- .../qemuxml2argv-q35-pm-disable-fallback.args | 2 +- .../qemuxml2argv-q35-pm-disable.args | 2 +- .../qemuxml2argv-q35-usb2-multi.args | 2 +- .../qemuxml2argv-q35-usb2-reorder.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-q35-usb2.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-q35.args | 2 +- .../qemuxml2argv-usb-controller-default-q35.args | 2 +- .../qemuxml2argv-usb-controller-explicit-q35.args | 2 +- tests/qemuxml2argvtest.c | 25 ++ .../qemuxml2xmlout-aarch64-virtio-pci-default.xml | 2 +- ...2xmlout-aarch64-virtio-pci-manual-addresses.xml | 2 +- .../qemuxml2xmlout-pci-expander-bus.xml | 207 +++++++++++ .../qemuxml2xmlout-pcie-expander-bus.xml | 384 +++++++++++++++++++++ .../qemuxml2xmlout-pcie-root-port.xml | 2 +- .../qemuxml2xmlout-pcie-root.xml | 2 +- .../qemuxml2xmlout-pcie-switch-downstream-port.xml | 2 +- .../qemuxml2xmlout-pcie-switch-upstream-port.xml | 2 +- .../qemuxml2xmlout-pcihole64-q35.xml | 2 +- .../qemuxml2xmlout-q35-usb2-multi.xml | 2 +- .../qemuxml2xmlout-q35-usb2-reorder.xml | 2 +- .../qemuxml2xmloutdata/qemuxml2xmlout-q35-usb2.xml | 2 +- tests/qemuxml2xmloutdata/qemuxml2xmlout-q35.xml | 2 +- tests/qemuxml2xmltest.c | 10 + 57 files changed, 2296 insertions(+), 261 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pci-expander-bus-bad-machine.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pci-expander-bus-bad-node.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pci-expander-bus.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pci-expander-bus.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pcie-expander-bus-bad-machine.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pcie-expander-bus.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pcie-expander-bus.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-pci-expander-bus.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-pcie-expander-bus.xml -- 2.5.5
