[libvirt] [PATCH 0/3] Properly deal with multiple netdevs per PCI device when converting VF <-> PF
by Laine Stump 07 Aug '17

07 Aug '17

The commit log of Patch 1 explains the majority of the reason for these patches. In short, they disambiguate the multiple netdevs per PCI device on the SRIOV PF and VFs of a Mellanox dual port NIC *when converting from a VF netdev to a PF netdev and vice versa*. This permits us to set the vlan tag and MAC address for the correct VF netdev (and detect the online status of the correct PF netdev for that VF) when using a VF in macvtap passthrough mode. (in other words, with these patches in place, it is possible to use *all* the VF netdevs on both ports of a dual port mellanox NIC for macvtap passthrough.) These patches *do not* solve the problem of saving/setting the mac address/vlan tag for both ports when using a dual port VF for PCI device assignment with VFIO (see my RFC email from yesterday). That is a much more complex problem. (These patches are a prerequisite to anything that might come out of that RFC though). Laine Stump (3): util: new function virNetDevGetPhysPortID() util: support matching a phys_port_id in virPCIGetNetName() util: match phys_port_id when converting PF-netdev to/from VF-netdev src/libvirt_private.syms | 1 + src/util/virhostdev.c | 2 +- src/util/virnetdev.c | 84 +++++++++++++++++++++++++++++++++++++++++++++--- src/util/virnetdev.h | 5 +++ src/util/virpci.c | 49 ++++++++++++++++++++++------ src/util/virpci.h | 4 ++- 6 files changed, 129 insertions(+), 16 deletions(-) -- 2.13.3

[libvirt] [PATCH] Remove bogus warning about vir$OBJECTGetConnect functions
by Daniel P. Berrange 07 Aug '17

07 Aug '17

The API docs for the various vir$OBJECTGetConnect functions contain a warning WARNING: When writing libvirt bindings in other languages, do not use this function. Instead, store the connection and the domain object together. There is no reason why language bindings should not use this method, and indeed the Perl, Python, and Go bindings all use these methods. This warning was originally added back in commit 3edb4bc9fb1b451599df58420d61ffd73633cead Author: Daniel Veillard <veillard(a)redhat.com> Date: Tue Jul 24 15:32:55 2007 +0000 * libvirt.spec.in NEWS docs/* po/*: preparing release 0.3.1 * src/libvirt.c python/generator.py: some cleanup and warnings from Richard W.M. Jones IIUC, the rational was that these APIs do not need to be directly exposed to the non-C language, as the language can expose the same concept itself by storing the original virConnectPtr object alongside the virDomainPtr. There's no reason to mandate such an approach though - it is valid for languages to expose this directly if that suits their needs better. Signed-off-by: Daniel P.

[libvirt] [PATCH v2] bhyve: Add support for VNC autoport
by Roman Bogorodskiy 06 Aug '17

06 Aug '17

From: Alexander Nusov <alexander.nusov(a)nfvexpress.com> This patch adds support for automatic VNC port assignment for bhyve guests. --- Changes from v1: * Call virPortAllocatorRelease() in virBhyveProcessStop() to release VNC port; that's done unconditionally of using autoport * Call virPortAllocatorSetUsed(.., true) in virBhyveProcessReconnect() to reserve already used VNC ports after daemon restart * Call virPortAllocatorSetUsed(.., true) in bhyveBuildGraphicsArgStr() for domains that don't use autoport so allocator didn't try to use ports allocated by these domains * In dryRun mode (i.e. for domxml-to-native) don't allocate any ports * Add a couple of unit tests Note 1: while adding tests I noticed that port allocator will actually skip already bound ports, so I'm wondering if it makes any sense to use virPortAllocatorSetUsed(.., true)? Right now I cannot come up with any case to trigger this except probably some races when spawning guests simultaneously, but that's hard to reproduce. Note 2: there are still some cases where resources allocated during command preparation are not properly cleaned up; that's not only VNC ports, but also TAP devices. I plan to add proper cleanup routines separately. src/bhyve/bhyve_command.c | 25 +++++++++++-- src/bhyve/bhyve_driver.c | 5 +++ src/bhyve/bhyve_process.c | 20 +++++++++++ src/bhyve/bhyve_utils.h | 3 ++ .../bhyvexml2argv-vnc-autoport.args | 12 +++++++ .../bhyvexml2argv-vnc-autoport.ldargs | 1 + .../bhyvexml2argv-vnc-autoport.xml | 26 ++++++++++++++ tests/bhyvexml2argvtest.c | 7 ++++ .../bhyvexml2xmlout-vnc-autoport.xml | 41 ++++++++++++++++++++++ tests/bhyvexml2xmltest.c | 1 + 10 files changed, 138 insertions(+), 3 deletions(-) create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-vnc-autoport.args create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-vnc-autoport.ldargs create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-vnc-autoport.xml create mode 100644 tests/bhyvexml2xmloutdata/bhyvexml2xmlout-vnc-autoport.xml diff --git a/src/bhyve/bhyve_command.c b/src/bhyve/bhyve_command.c index eae5cb3ca..e62b5df66 100644 --- a/src/bhyve/bhyve_command.c +++ b/src/bhyve/bhyve_command.c @@ -330,15 +330,19 @@ bhyveBuildLPCArgStr(const virDomainDef *def ATTRIBUTE_UNUSED, } static int -bhyveBuildGraphicsArgStr(const virDomainDef *def ATTRIBUTE_UNUSED, +bhyveBuildGraphicsArgStr(const virDomainDef *def, virDomainGraphicsDefPtr graphics, virDomainVideoDefPtr video, virConnectPtr conn, - virCommandPtr cmd) + virCommandPtr cmd, + bool dryRun) { virBuffer opt = VIR_BUFFER_INITIALIZER;
