[libvirt] [PATCH] pci: properly handle out-of-order SRIOV virtual functions
by Laine Stump 06 Nov '13

06 Nov '13

This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1025397 When libvirt creates the list of an SRIOV Physical Function's (PF) Virtual Functions (VF), it assumes that the order of "virtfn*" links returned by readdir() from the PF's sysfs directory is already in the correct order. Experience has shown that this is not always the case. This results in 1) incorrect assumptions made by consumers of the output of the virt_functions list of virsh nodedev-dumpxml, and 2) setting MAC address and vlan tag on the wrong VF (since libvirt uses netlink to set mac address and vlan tag, netlink requires the VF#, and the function virPCIGetVirtualFunctionIndex() returns the wrong index due to the improperly ordered VF list). See the bugzilla report for an example of this improper behavior. The solution provided by this patch is for virPCIGetVirtualFunctions to first gather all the "virtfn*" names from the PFs sysfs directory, then allocate a virtual_functions array large enough to hold all entries, and finally to create a device entry for each virtfn* name and place it into the virtual_functions array at the proper index (based on interpreting the value following "virtfn" in the name). Checks are introduced to ensure that 1) the virtfn list given in sysfs is not sparse (ie, there are no indexes larger than the length of the list), and that no two virtfn* entries decode to the same index. --- I briefly debated solving this problem by changing the virtual_functions array from being just a list of PCI device addresses into being an array of new objects that have both a PCI address and a virtual function index. I decided against it because it would have modified the XML format and required more substantial changes to other parts of the code (and anyway is unnecessary, since the virtual function array is never "sparse", so it can be appropriately represented by implying the virtual function index from a device's position in the list). src/util/virpci.c | 91 ++++++++++++++++++++++++++++++++++++++++--------------- 1 file changed, 66 insertions(+), 25 deletions(-) diff --git a/src/util/virpci.c b/src/util/virpci.c index 148631f..e70fa3d 100644 --- a/src/util/virpci.c +++ b/src/util/virpci.c @@ -2379,6 +2379,8 @@ virPCIGetPhysicalFunction(const char *vf_sysfs_path, return ret; } +static const char *virtfnPrefix = "virtfn"; + /* * Returns virtual functions of a physical function */ @@ -2393,6 +2395,8 @@ virPCIGetVirtualFunctions(const char *sysfs_path, struct dirent *entry = NULL; char *device_link = NULL; char errbuf[64]; + char **virtfnNames = NULL; + size_t nVirtfnNames = 0; VIR_DEBUG("Attempting to get SR IOV virtual functions for device" "with sysfs path '%s'", sysfs_path); @@ -2411,51 +2415,88 @@ virPCIGetVirtualFunctions(const char *sysfs_path, while ((entry = readdir(dir))) { if (STRPREFIX(entry->d_name, "virtfn")) { - virPCIDeviceAddress *config_addr = NULL; + char *tempName; - if (virBuildPath(&device_link, sysfs_path, entry->d_name) == -1) { - virReportOOMError(); + /* save these to sort into virtual_functions array */ + if (VIR_STRDUP(tempName, entry->d_name) < 0) + goto error; + if (VIR_APPEND_ELEMENT(virtfnNames, nVirtfnNames, tempName) < 0) { + VIR_FREE(tempName); goto error; } + } + } - VIR_DEBUG("Number of virtual functions: %d", - *num_virtual_functions); + /* pre-allocate because we will be filling in out of order */ + if (nVirtfnNames && VIR_ALLOC_N(*virtual_functions, nVirtfnNames) < 0) + goto error; + *num_virtual_functions = nVirtfnNames; - if (virPCIGetDeviceAddressFromSysfsLink(device_link, - &config_addr) != - SRIOV_FOUND) { - VIR_WARN("Failed to get SRIOV function from device " - "link '%s'", device_link); - VIR_FREE(device_link); - continue; - } + for (i = 0; i < nVirtfnNames; i++) { + virPCIDeviceAddress *config_addr = NULL; + unsigned int virtfnIndex; - if (VIR_REALLOC_N(*virtual_functions, - *num_virtual_functions + 1) < 0) { - VIR_FREE(config_addr); - goto error; - } + if (virBuildPath(&device_link, sysfs_path, virtfnNames[i]) < 0) { + virReportOOMError(); + goto error; + } + + if (virStrToLong_ui(virtfnNames[i] + strlen(virtfnPrefix), + 0, 10, &virtfnIndex) < 0) { + virReportError(VIR_ERR_INTERNAL_ERROR, + _("Invalid virtual function link name '%s' " + "in physical function directory '%s'"), + virtfnNames[i], sysfs_path); + goto error; + } + + if (virtfnIndex >= nVirtfnNames) { + virReportError(VIR_ERR_INTERNAL_ERROR, + _("Virtual function link name '%s' larger than " + "total count of virtual functions %zu " + "in physical function directory '%s'"), + virtfnNames[i], nVirtfnNames, sysfs_path); + goto error; + } - (*virtual_functions)[*num_virtual_functions] = config_addr; - (*num_virtual_functions)++; + if ((*virtual_functions)[virtfnIndex]) { + virReportError(VIR_ERR_INTERNAL_ERROR, + _("Virtual function link name '%s' " + "generates duplicate index %zu " + "in physical function directory '%s'"), + virtfnNames[i], nVirtfnNames, sysfs_path); + goto error; + } + + if (virPCIGetDeviceAddressFromSysfsLink(device_link, &config_addr) != + SRIOV_FOUND) { + VIR_WARN("Failed to get SRIOV function from device link '%s'", + device_link); VIR_FREE(device_link); + continue; } + + VIR_DEBUG("Found virtual function %d", virtfnIndex); + (*virtual_functions)[virtfnIndex] = config_addr; + VIR_FREE(device_link); } + VIR_DEBUG("Number of virtual functions: %d", *num_virtual_functions); ret = 0; cleanup: + for (i = 0; i < nVirtfnNames; i++) + VIR_FREE(virtfnNames[i]); + VIR_FREE(virtfnNames); VIR_FREE(device_link); if (dir) closedir(dir); return ret; error: - if (*virtual_functions) { - for (i = 0; i < *num_virtual_functions; i++) - VIR_FREE((*virtual_functions)[i]); - VIR_FREE(*virtual_functions); - } + for (i = 0; i < *num_virtual_functions; i++) + VIR_FREE((*virtual_functions)[i]); + VIR_FREE(*virtual_functions); goto cleanup; } -- 1.8.3.1

[libvirt] Live migration for containers - Was "RE: libvirt support for LXC"
by Christian Benvenuti (benve) 06 Nov '13

06 Nov '13

Hello, based on the 3D below, it seems that the most logical way to add support for container live migration to libvirt is to integrate the latter with CRIU. If I understand it correctly, Daniel's suggestion below would be that of - 1st converting CRIU to a library - 2nd making libvirt use that library to C/R the container/s CRIU has recently announced support for CRIU as a service and the reason why they opted for a service instead of a library [1] seems to be associated with a use case they had: ability for an application to invoke a self-dump C/R In Libvirt's case it would not be the container to ask for a self dump, but it would be libvirt itself to orchestrate it. In light of the new CRIU as a service feature, is libvirt's preference still that of using a library? Would a service be equally good? Is there anyone actively working or looking at this (libvirt+CRIU)?

[libvirt] [PATCH] virpcitst: Introduce testVirPCIDeviceReset
by Michal Privoznik 06 Nov '13

06 Nov '13

This addition, however, requires some refactoring to be done. First of all, to match the best practice we should detach the device prior resetting it. That's why testVirPCIDeviceDetach is detaching all devices within 0000:00:01.0 and 0000:00:03.0 range. Then, the brand new test will reset the 0000:00:02.0 device, so the last testVirPCIDeviceReattach can reattach all the devices back. In order to perform a PCI device reset, the dummy config file is not sufficient anymore and must be replaced with real PCI config (binary mess). Such config files are to be stored under tests/virpcitestdata/ and ought to have '.config' suffix.

[libvirt] GenericVmConfigFault - Unable to allocate a PCI SCSI adapter. Too many PCI devices are already configured.
by Andrew Holway 06 Nov '13

Hello, I am trying to create virtual machines on a VMware ESXi 5.5.0 build-1331820 with Virsh 1.1.4 on Fedora 19. I see the following. Can anyone show me where I am going wrong or perhaps suggest a more sensible way of spawning virtual machines on ESXi with libvirt.
