[libvirt] Question about virtio-pci in Aarch64
by Kevin Zhao 19 Aug '16

19 Aug '16

Hi Cole && All, Nice meeting you in the libvirt mail-list. Greetings from Linaro !!! I am Kevin Zhao from Linaro and working for OpenStack on Aarch64. Nowadays I find that the default "virtio" bus is "virtio-mmio" , not "virtio-pci". Since virtio-mmio do not has the host plugged function , something is wrong with the function in OpenStack Nova. Then I search and find some mail information as belows by Cole :-) 1) https://www.redhat.com/archives/libvir-list/2015-December/msg00217.html 2) https://www.redhat.com/archives/libvir-list/2016-March/msg00167.html I see some efforts have been doing by you. Really thanks for your efforts for Aarch64. And I have some small questions. 1. Is Libvirt planning to replace the default virtio-mmio to virtio-pci for Aarch64? 2. If not , how can I change the xml file(generated by Virsh) for virtio-pci so that Qemu can recognize it ? Really big thanks for your help. Looking forwards to your response! Best Regards, Kevin Zhao

[libvirt] [PATCH 0/7]
by Nikolay Shirokovskiy 18 Aug '16

18 Aug '16

filesystem pools inception Filesystem pools is a facility to manage filesystems resources similar to how storage pools manages volume resources. Furthermore new API follows storage API closely where it makes sense. Uploading/downloading operations are not defined yet as it is not obvious how to make it properly. I guess we can use some kind of tar to make a stream from a filesystem. Please share you thoughts on this particular issue. The patchset provides 'dir' backend which simply expose directories in some directory in host filesystem. The virsh commands are provided too. So it is ready to play with, just replace 'pool' in xml descriptions and virsh commands to 'fspool' and 'volume' to 'item'. Olga Krishtal (7): fspool: introduce filesystem pools API fspool: usual driver based implementation of filesystem pools API fspools: configuration and internal representation fspools: acl support for filesystem pools remote: filesystem pools driver implementation fspool: default implementation of filesystem pools virsh: filesystem pools commands configure.ac | 33 + daemon/Makefile.am | 4 + daemon/libvirtd.c | 10 + daemon/remote.c | 35 + include/libvirt/libvirt-fs.h | 273 +++++ include/libvirt/libvirt.h | 1 + include/libvirt/virterror.h | 8 + po/POTFILES.in | 6 + src/Makefile.am | 46 + src/access/viraccessdriver.h | 12 + src/access/viraccessdrivernop.c | 19 + src/access/viraccessdriverpolkit.c | 47 + src/access/viraccessdriverstack.c | 49 + src/access/viraccessmanager.c | 31 + src/access/viraccessmanager.h | 11 + src/access/viraccessperm.c | 15 +- src/access/viraccessperm.h | 124 +++ src/conf/fs_conf.c | 1624 +++++++++++++++++++++++++++ src/conf/fs_conf.h | 310 ++++++ src/datatypes.c | 154 +++ src/datatypes.h | 94 ++ src/driver-fs.h | 210 ++++ src/driver.h | 3 + src/fs/fs_backend.h | 85 ++ src/fs/fs_backend_dir.c | 334 ++++++ src/fs/fs_backend_dir.h | 8 + src/fs/fs_driver.c | 2164 ++++++++++++++++++++++++++++++++++++ src/fs/fs_driver.h | 10 + src/libvirt-fs.c | 1715 ++++++++++++++++++++++++++++ src/libvirt.c | 28 + src/libvirt_private.syms | 53 + src/libvirt_public.syms | 46 + src/remote/remote_driver.c | 72 +- src/remote/remote_protocol.x | 522 ++++++++- src/rpc/gendispatch.pl | 19 +- src/util/virerror.c | 37 + tools/Makefile.am | 4 + tools/virsh-fspool.c | 1728 ++++++++++++++++++++++++++++ tools/virsh-fspool.h | 36 + tools/virsh-item.c | 1274 +++++++++++++++++++++ tools/virsh-item.h | 37 + tools/virsh.c | 4 + tools/virsh.h | 9 + 43 files changed, 11294 insertions(+), 10 deletions(-) create mode 100644 include/libvirt/libvirt-fs.h create mode 100644 src/conf/fs_conf.c create mode 100644 src/conf/fs_conf.h create mode 100644 src/driver-fs.h create mode 100644 src/fs/fs_backend.h create mode 100644 src/fs/fs_backend_dir.c create mode 100644 src/fs/fs_backend_dir.h create mode 100644 src/fs/fs_driver.c create mode 100644 src/fs/fs_driver.h create mode 100644 src/libvirt-fs.c create mode 100644 tools/virsh-fspool.c create mode 100644 tools/virsh-fspool.h create mode 100644 tools/virsh-item.c create mode 100644 tools/virsh-item.h -- 1.8.3.1

[libvirt] [PATCH v1 00/19] Implementation of QEMU vhost-scsi
by Eric Farman 17 Aug '16

17 Aug '16

This patch series provides a libvirt implementation of the vhost-scsi interface in QEMU. As near as I can see, this was discussed upstream in July 2014[1], and ended in a desire to replace a vhost-scsi controller in favor of a hostdev element instead[2]. There is no capability check in this series for vhost-scsi in the underlying QEMU. Using a recent QEMU built with --disable-vhost-scsi fails with "not a valid device model name." Host Filesystem Example: # ls /sys/kernel/config/target/vhost/ discovery_auth naa.5001405df3e54061 version # ls /sys/kernel/config/target/vhost/naa.5001405df3e54061/tpgt_1/lun/ lun_0 QEMU Example (snippet): -device vhost-scsi-ccw,wwpn=naa.5001405df3e54061,devno=fe.0.1000 Libvirt Example (snippet): <hostdev mode='subsystem' type='scsi'> <source protocol='vhost' wwpn='naa.5001405df3e54061'/> <address type='ccw' cssid='0xfe' ssid='0x0' devno='0x1000'/> </hostdev> Guest Viewpoint: # lsscsi [1:0:1:0] disk LIO-ORG disk0 4.0 /dev/sda # dmesg | grep 1: [ 6.065735] scsi host1: Virtio SCSI HBA [ 6.093892] scsi 1:0:1:0: Direct-Access LIO-ORG disk0 4.0 PQ: 0 ANSI: 5 [ 6.313615] sd 1:0:1:0: Attached scsi generic sg0 type 0 [ 6.314981] sd 1:0:1:0: [sda] 29360128 512-byte logical blocks: (15.0 GB/14.0 GiB) [ 6.317290] sd 1:0:1:0: [sda] Write Protect is off [ 6.317566] sd 1:0:1:0: [sda] Mode Sense: 43 00 10 08 [ 6.317853] sd 1:0:1:0: [sda] Write cache: enabled, read cache: enabled, supports DPO and FUA [ 6.352722] sd 1:0:1:0: [sda] Attached SCSI disk [1] http://www.redhat.com/archives/libvir-list/2014-July/msg01235.html [2] http://www.redhat.com/archives/libvir-list/2014-July/msg01390.html Eric Farman (19): conf: Add definitions for "vhost" protocol in hostdev tags util: Allow a vhost protocol for scsi hostdev security: Allow a vhost protocol for scsi hostdev qemu: Refactor qemuIsSharedHostdev for readability/extendability qemu: Allow a vhost protocol for scsi hostdev conf: Parse vhost-scsi XML tag conf: Prevent use of shareable on vhost-scsi devices qemu: Introduce vhost-scsi capability qemu: Refactor qemuBuildHostdevCommandLine for non-vhost devices qemu: Add vhost-scsi string for -device parameter qemu: Add vhost-scsi to hostdev schema docs: Add vhost-scsi to documentation qemu: Refactor hotplug in preparation for vhost-scsi qemu: Allow hotplug of vhost-scsi device conf: Create vhost-scsi hostdev protocol in dumpxml conf: Set up vhost-scsi hostdev to self-close source tag tests: Introduce basic vhost-scsi test conf: Do not create a virtio-scsi controller for vhost-scsi hostdev qemu: Allow the specification of a vhost-scsi devno docs/formatdomain.html.in | 16 +++ docs/schemas/domaincommon.rng | 12 +++ src/conf/domain_conf.c | 94 ++++++++++++++-- src/conf/domain_conf.h | 8 ++ src/libvirt_private.syms | 1 + src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_cgroup.c | 5 + src/qemu/qemu_command.c | 120 +++++++++++++++++++-- src/qemu/qemu_command.h | 6 ++ src/qemu/qemu_conf.c | 21 +++- src/qemu/qemu_domain_address.c | 10 ++ src/qemu/qemu_hotplug.c | 76 +++++++++---- src/qemu/qemu_monitor.c | 21 ++++ src/qemu/qemu_monitor.h | 4 + src/security/security_apparmor.c | 5 +- src/security/security_dac.c | 10 +- src/security/security_selinux.c | 10 +- src/util/virhostdev.c | 13 ++- src/util/virscsi.c | 26 +++++ src/util/virscsi.h | 1 + tests/qemucapabilitiesdata/caps_1.5.3.x86_64.xml | 1 + tests/qemucapabilitiesdata/caps_1.6.0.x86_64.xml | 1 + tests/qemucapabilitiesdata/caps_1.7.0.x86_64.xml | 1 + tests/qemucapabilitiesdata/caps_2.1.1.x86_64.xml | 1 + tests/qemucapabilitiesdata/caps_2.4.0.x86_64.xml | 1 + tests/qemucapabilitiesdata/caps_2.5.0.x86_64.xml | 1 + .../caps_2.6.0-gicv2.aarch64.xml | 1 + .../caps_2.6.0-gicv3.aarch64.xml | 1 + tests/qemucapabilitiesdata/caps_2.6.0.ppc64le.xml | 1 + tests/qemucapabilitiesdata/caps_2.6.0.x86_64.xml | 1 + .../qemuxml2argv-hostdev-scsi-vhost-scsi.args | 24 +++++ .../qemuxml2argv-hostdev-scsi-vhost-scsi.xml | 33 ++++++ tests/qemuxml2argvmock.c | 12 +++ tests/qemuxml2argvtest.c | 3 + 35 files changed, 486 insertions(+), 58 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hostdev-scsi-vhost-scsi.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hostdev-scsi-vhost-scsi.xml -- 1.9.1
