[libvirt] [PATCH 00/10] libxl: PVHv2 support
by Marek Marczykowski-Górecki 25 Sep '18

25 Sep '18

This is a respin of my old PVHv1 patch[1], converted to PVHv2. Should the code use "PVH" name (as libxl does internally), or "PVHv2" as in many places in Xen documentation? I've chosen the former, but want to confirm it. Also, not sure about VIR_DOMAIN_OSTYPE_XENPVH (as discussed on PVHv1 patch) - while it will be messy in many cases, there is libxl_domain_build_info.u.{hvm,pv,pvh} which would be good to not mess up. Also, PVHv2 needs different kernel features than PV (CONFIG_XEN_PVH vs CONFIG_XEN_PV), so keeping the same VIR_DOMAIN_OSTYPE_XEN could be confusing. On the other hand, libxl_domain_build_info.u.pv is used in very few places (one section of libxlMakeDomBuildInfo), so guarding u.hvm access with VIR_DOMAIN_OSTYPE_HVM may be enough. For now I've reused VIR_DOMAIN_OSTYPE_XEN - in the driver itself, most of the code is the same as for PV. Since PVHv2 relies on features in newer Xen versions, I needed to convert also some older code. For example b_info->u.hvm.nested_hvm was deprecated in favor of b_info->nested_hvm. While the code do handle both old and new versions (obviously refusing PVHv2 if Xen is too old), this isn't the case for tests. How it should be handled, if at all? First few preparatory patches can be applied independently.

[libvirt] [libvirt PATCH v3 0/4] Share cgroup code that is duplicated between QEMU and LXC
by Fabiano Fidêncio 24 Sep '18

24 Sep '18

virLXCCgroupSetupBlkioTune() and qemuSetupBlkioCgroup() and virLXCCgroupSetupCpuTune() and qemuSetupCpuCgroup() are the most similar functions between QEMU and LXC code. Let's move their common code to virCgroup. Mind that the first two patches are basically preparing the ground for the changes introduced in the last two patches. I know that Pavel Hrdina suggested taking a different path[0] for this series but I do believe Michal's and Jano's points are valid, thus I've decided to just do the changes suggested by Michal (at least for now). [0]: https://www.redhat.com/archives/libvir-list/2018-September/msg00534.html changes since v1: - Michal Privoznik pointed out (as did the `make syntax-check` :-)) that we do want to keep src/util independently of the parsing code (thus, including "conf/domain_conf.h" in vircgroup.h is not the way to go). This has been solved now by partially following Michal's suggestion and splitting the structs and functions that would be use in the common code to new different files. changes since v2: - Fixed `make syntax-check` errors that I've missed before (didn't have cppi installed); - Created a new section in src/libvirt_private.syms to correctly export the virBlkioDeviceArrayClear symbol; - Removed a virlkio.c from libvirt_setuid_rpc_client_la__SOURCES (why did I add it there in the first place? ;-)) - Explicitly included virmem.h in qemu_{domain,command}.c. Although there's nothing enforcing it, I do believe it's a good practive that should be followed and I've checked with Andrea and Peter about doing that and both agreed with the approach.

[libvirt] [PATCH v2 00/13] Implement vsh-table API to virsh and virt-admin
by Simon Kobyda 24 Sep '18

24 Sep '18

API is implemented in virsh and virt-admin. It fixes problems with table-alignment, makes tables more readable and deals with unicode. Table however could not be implemented in places, which do use simple lists, or table implementation would change content of output, which users might rely on. If you know about other place where it could be implemented, let me know. https://bugzilla.redhat.com/show_bug.cgi?id=1574624 https://bugzilla.redhat.com/show_bug.cgi?id=1584630 Changes in v2: - Implemented gettext function - Fixed few possible leaks caused by inserting "goto cleanup" statements - Implemented VIR_AUTOFREE where it's appropriate Simon Kobyda (13): virsh: Implement vsh-table to iface-list virsh: Implement vshTable API to net-list and net-dhcp-leases virsh: Implement vshTable API to secret-list virsh: Implement vshTable API to nwfilter-list and nwfilterbinding-list virsh: Implement vshTable API to snapshot-list. virsh: Set up cmdDomblkinfo() and cmdDomblkinfoPrint() for vshTable API implementation virsh: Implement vshTable API to domblkinfo virsh: Implement vshTable API to domblklist virsh: Implement vshTable API to domiflist virsh: Implement vshTable API to vcpupin, iothreadinfo, domfsinfo virsh: Implement vshTable API to pool-list virsh: Implement vshTable API to vol-list virt-admin: Implement vshTable API to server-list and client-list tools/virsh-domain-monitor.c | 147 ++++++++++++++++--------------- tools/virsh-domain.c | 98 +++++++++++++++------ tools/virsh-interface.c | 27 ++++-- tools/virsh-network.c | 59 ++++++++----- tools/virsh-nwfilter.c | 47 +++++++--- tools/virsh-pool.c | 162 +++++++---------------------------- tools/virsh-secret.c | 28 ++++-- tools/virsh-snapshot.c | 33 ++++--- tools/virsh-volume.c | 129 ++++++---------------------- tools/virt-admin.c | 47 +++++++--- 10 files changed, 371 insertions(+), 406 deletions(-) -- 2.17.1

[libvirt] [PATCH] qemuProcess: update hostdevs before connectting qemu monitor
by Wu Zongyong 22 Sep '18

22 Sep '18

In a following case: virsh start $domain service libvirtd stop <shutdown> the guest from within the $domain service libvirtd start Notice that PCI devices which have been assigned to the $domain will still be bound to stub drivers instead rebound to host drivers. In that case the call stack is like below: libvirtd start qemuProcessReconnect qemuProcessStop qemuHostdevReAttachDomainDevices qemuHostdevReAttachPCIDevices virHostdevReAttachPCIDevices qemuHostdevUpdateActiveDomainDevices won't be called because the monitor channel is closed. So host devices in $domain will not be added to either activePCIHostdevs list or inactivePCIHostdev list. And therefore, virHostdevReAttachPCIDevices just neglects these host PCI devices which are bound to stub drivers and don't rebind them to host drivers. This patch fixs that by moving qemuHostdevUpdateActiveDomainDevices before qemuConnectMonitor.
