[libvirt] [PATCH] networkGetDHCPLeases: Don't always report error if unable to read leases file
by Michal Privoznik 26 Jul '18

26 Jul '18

https://bugzilla.redhat.com/show_bug.cgi?id=1600468 If we are unable to read leases file (no matter what the reason is), we return 0 - just like if there were no leases. However, because we use virFileReadAll() an error is printed into the log. Note that not all networks have leases file - only those for which we start dnsmasq.

[libvirt] [PATCH] nwfilter: Resolve SEGV for NWFilter Snoop processing
by John Ferlan 25 Jul '18

25 Jul '18

https://bugzilla.redhat.com/show_bug.cgi?id=1599973 Commit id fca9afa08 changed the @req->ifname to use @req->binding->portdevname fillingin the @req->binding in a similar way that @req->ifname would have been filled in during virNWFilterDHCPSnoopReq processing. However, in doing so it did not take into account some code paths where the @req->binding should be checked instead of @req->binding->portdevname. These checks led to SEGVs in some cases during libvirtd reload processing in virNWFilterSnoopRemAllReqIter (for stop during nwfilterStateCleanup processing) and virNWFilterSnoopReqLeaseDel (for start during nwfilterStateInitialize processing). In particular, when reading the nwfilter.leases file a new @req is created, but the @req->binding is not filled in. That's left to virNWFilterDHCPSnoopReq processing which checks if the @req already exists in the @virNWFilterSnoopState.snoopReqs hash table after adding a virNWFilterSnoopState.ifnameToKey entry for the @req->binding->portdevname by a @ref->ikey value. NB: virNWFilterSnoopIPLeaseInstallRule and virNWFilterDHCPSnoopThread do not need the req->binding check since they can only be called after the filter->binding is created/assigned.

[libvirt] interactions between virDomainSetVcpusFlags and NUMA/pinning?
by Chris Friesen 25 Jul '18

25 Jul '18

Hi, Just wondering about interactions between virDomainSetVcpusFlags() and virDomainPinVcpuFlags() and the domain XML. 1) If I add a vCPU to a domain, do I need to pin it after or does it respect the vCPU-to-pCPU mapping specified in the domain XML? 2) Are vCPUs added/removed in strict numerical order such that at any given time the active vCPUs are numbered 0-(N-1) where N is the number of active vCPUs? 3) Will the newly-added vCPUs respect the NUMA topology specified in the domain XML? Thanks, Chris

[libvirt] [PATCH v3 0/3] Alter qemu live/cold device attach algorithm
by John Ferlan 25 Jul '18

25 Jul '18

v2: https://www.redhat.com/archives/libvir-list/2018-July/msg00361.html Differences to v2: Patch1: NEW - As a result of code review the suggestion was to utilize the virDomainDefCompatibleDevice in order to make the check more generic to include <disk>'s which were also afflicted with the same problem that I was trying to solve with the former patch1 just for <hostdev>'s. However, this led me down into the abyss of more changes since <disk>'s have multiple <address type='drive'...> target bus types (IDE and SCSI). That means we need to have a mechanism to pass the target bus along so that a SCSI drive address doesn't inadvertently match an IDE drive address. All that is complicated by the way virDomainDefHasDeviceAddress iterates through all the device lists. Whether there are more similar devices I'm assuming will fall out of code review. Patch2: This moves the virDomainDefHasDeviceAddress into the more common config checking virDomainDefCompatibleDevice method, but now needs to also account for the disk bus issue. This theoretically could be combined with Patch1, but keeping them separate I would hope makes for simpler code review. I could also move code out of virDomainDefHasDeviceAddressIterator into patch2, but if just felt better in patch1. Patch3: No changes were made (amazingly so). In the end quite a bit more complicated John Ferlan (3): conf: Add @target_bus to virDomainDefHasDeviceAddress qemu: Check for existing address when cold attach device qemu: Use the correct vm def on cold attach src/conf/domain_conf.c | 54 +++++++++++++++++++++++++++++++++++--- src/conf/domain_conf.h | 3 ++- src/qemu/qemu_driver.c | 59 ++++++++++++++++-------------------------- 3 files changed, 75 insertions(+), 41 deletions(-) -- 2.17.1

[libvirt] [PATCH v3 0/2] Support network stats for VF representor interface
by Jai Singh Rana 25 Jul '18

25 Jul '18

With availability of switchdev model in linux, it is possible to capture stats for SR-IOV device with interface_type as 'hostdev' provided device supports VF represontor in switchdev mode[1] on host. These stats are supported by adding helper APIs for getting/verifying VF representor name based on PCI Bus:Device:Function information in domains 'hostdev' structure and querying required net sysfs directory and file entries on host according to switchdev model. These helper APIs are then used in qemu/conf to get the interface stats for VF representor on host of pci SR-IOV device.
