[libvirt] [PATCH/GSoC] Use virGetLastErrorMessage() rather than open code it

getting err using virGetLastError() and then retrieving message from err make developer have to test the value of err and err->message and default to self-defined unkown error message.

[libvirt] [PATCH v2] add func to set shared drivers after libvirtd init
by Mikhail Feoktistov 08 Apr '16

Diff from v1: Remove vz prefix from the title of this letter. Because this is the common case for all drivers in libvirt. Description: Built-in drivers in libvirt are initialized before libvirtd initialization. Libvirt loads shared drivers on libvirtd initialization step.

[libvirt] [PATCH v2] host-validate: Improve CPU flags processing
by Andrea Bolognani 07 Apr '16

07 Apr '16

Instead of relying on substring search, tokenize the input and process each CPU flag separately. This ensures CPU flag detection will continue to work correctly even if we start looking for CPU flags whose name might appear as part of other CPU flags' names. The result of processing is stored in a virBitmap, which means we don't have to parse /proc/cpuinfo in its entirety for each single CPU flag we want to check. Moreover, use of the newly-introduced virHostValidateCPUFlag enumeration ensures we don't go looking for random CPU flags which might actually be simple typos. --- Changes in v2: * use virStringSplitCount() and STRPREFIX() instead of strtok_r() and strcmp(), as suggested by Peter tools/virt-host-validate-common.c | 67 ++++++++++++++++++++++++++++++++------- tools/virt-host-validate-common.h | 13 +++++++- tools/virt-host-validate-qemu.c | 12 +++++-- 3 files changed, 77 insertions(+), 15 deletions(-) diff --git a/tools/virt-host-validate-common.c b/tools/virt-host-validate-common.c index 8ebf73e..3305a32 100644 --- a/tools/virt-host-validate-common.c +++ b/tools/virt-host-validate-common.c @@ -31,7 +31,6 @@ #endif /* HAVE_MNTENT_H */ #include <sys/stat.h> -#include "virutil.h" #include "viralloc.h" #include "virfile.h" #include "virt-host-validate-common.h" @@ -39,6 +38,10 @@ #define VIR_FROM_THIS VIR_FROM_NONE +VIR_ENUM_IMPL(virHostValidateCPUFlag, VIR_HOST_VALIDATE_CPU_FLAG_LAST, + "vmx", + "svm"); + static bool quiet; void virHostMsgSetQuiet(bool quietFlag) @@ -188,29 +191,64 @@ int virHostValidateNamespace(const char *hvname, } -bool virHostValidateHasCPUFlag(const char *name) +virBitmapPtr virHostValidateGetCPUFlags(void) { - FILE *fp = fopen("/proc/cpuinfo", "r"); - bool ret = false; + FILE *fp; + virBitmapPtr flags; - if (!fp) - return false; + if (!(fp = fopen("/proc/cpuinfo", "r"))) + return NULL; + + if (!(flags = virBitmapNewQuiet(VIR_HOST_VALIDATE_CPU_FLAG_LAST))) + return NULL; do { char line[1024]; + char *start; + char **tokens; + size_t ntokens; + size_t i; if (!fgets(line, sizeof(line), fp)) break; - if (strstr(line, name)) { - ret = true; - break; + /* The line we're interested in is marked either as "flags" or + * as "Features" depending on the architecture, so check both + * prefixes */ + if (!STRPREFIX(line, "flags") && !STRPREFIX(line, "Features")) + continue; + + /* fgets() includes the trailing newline in the output buffer, + * so we need to clean that up ourselves.

[libvirt] [PATCH v2 0/4] Add a domain masterKey secret for qemu,
by John Ferlan 06 Apr '16

06 Apr '16

v1: http://www.redhat.com/archives/libvir-list/2016-March/msg01206.html Patch 1 is already ACK'd. I assume this code won't go into 1.3.3, but would hopefully be early in 1.3.4 and I didn't want to break up the capability bits across releases... Differences to v1 - Patch 2 is new - it's taking the virUUIDGenerateRandomBytes and making it generic since we'll use it in Patch 3 (it already opens/reads from /dev/urandom, so I figured it'd be better to share than cut, copy, paste). - Patch 3 has changes from review: * Less comments in qemuDomainGetMasterKeyFilePath * Master key no longer base64 encoded to be written (or read). Instead the Write code will open, truncate, and write the secret directly. The Read code will read the secret directly * The fallback algorithm for key generation uses virGenerateRandomBytes * Changed 'masterKey' from "char *" to "uint8_t *" and added the masterKeyLen - Patch 4 changes in order to tell qemu the format of the file is 'raw'. Also affects test .args file Removed references to encode/decode, adjusted commit messages. Ran through Coverity checker... happy... Created a domain that would pass/read the file... Killed libvirtd, restarted and read the masterKey file properly. Also ensured the #else of the secret generation compiled...

[libvirt] [PATCH v5 0/6] storage:dir: ploop volumes support
by Olga Krishtal 06 Apr '16

06 Apr '16

This series of patches introduces the support of ploop volumes in storage pools (dir, fs, etc). Ploop volume is a disk loopback block device consists of root.hds (it is the image file) and DiskDescriptor.xml: https://openvz.org/Ploop/format. Due to this fact it can't be treated as file or any other volume type, moreover, in order to successfully manipulate with such volume, ploop tools should be installed. All callbacks except the wipeVol are supported. First patch introduces ploop volume type. This is a directory with two files inside. The name of the directory is the name of the volume. Patch 2 deals with creating an empty volume and cloning the existing one. Clone is done via simle cp operation. If any of this operation fails - directory will be deleted. Patch 3 deletes recursively ploop directory. Patch 4 uses ploop tool to resize volume. Patch 6 adapts all refreshing functions to work with ploop. To get information the directory is checked. The volume is treated as the ploops one only if it contains ploop files. Every time the pool is refreshed DiskDescriptor.xml is restored. This is necessary, because the content of the volume may have changed. Upload and download (patch 7) can't be done if the volume contains snapshots. v5: - added ploop volume type - there is no change in opening volume functions. Now reopening takes place is the volume is ploops one. - restore DiskDescriptor.xml every refresh pool - all information, except format is taken from header - forbidden upload and download ops for volume with snapshots - there is no separate function for deleting the volume - fixed identation and leaks v4: - fixed identation issues. - in case of .uploadVol, DiskDescriptor.xml is restored. - added check of ploops'accessibility v3: - no VIR_STORAGE_VOL_PLOOP type any more - adapted all patches according to previous change - fixed comments v2: - fixed memory leak - chenged the return value of all helper functions to 0/-1. Now check for success is smth like that: vir****Ploop() < 0 - fixed some identation issues.

[libvirt] [PATCH] spec: Include KVM support on RHEL 7 ppc64 and newer
by Andrea Bolognani 06 Apr '16

06 Apr '16

--- Definitely not an expert on spec files, but I did a test build on RHEL 7.2 ppc64le and it resulted in libvirt-daemon-driver-qemu-1.3.3-1.el7.ppc64le.rpm libvirt-daemon-kvm-1.3.3-1.el7.ppc64le.rpm libvirt-lock-sanlock-1.3.3-1.el7.ppc64le.rpm being built in addition to what was built even before, so it looks reasonable I guess?
