[libvirt] [PATCHv3] Add invariant TSC cpu flag

by Ján Tomko

Add suport for invariant TSC flag (CPUID 0x80000007, bit 8 of EDX). If this flag is enabled, the TSC ticks at a constant rate across all ACPI P-, C- and T-states. This can be enabled by adding: <feature name='invtsc'/> to the <cpu> element. Migration and saving the domain does not work with this flag. QEMU support for this is not merged yet: https://lists.gnu.org/archive/html/qemu-devel/2014-04/msg05024.html The feature name "invtsc" differs from the name "" used by the linux kernel: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch... --- v1: https://www.redhat.com/archives/libvir-list/2014-May/msg00183.html v2: https://www.redhat.com/archives/libvir-list/2014-May/msg00297.html add it as a cpu flag instead of a timer v3: check if the feature wasn't filtered out on domain startup src/cpu/cpu_map.xml | 5 +++++ src/qemu/qemu_migration.c | 14 ++++++++++++++ src/qemu/qemu_process.c | 15 +++++++++++++++ 3 files changed, 34 insertions(+) diff --git a/src/cpu/cpu_map.xml b/src/cpu/cpu_map.xml index 7d34d40..ffaeb92 100644 --- a/src/cpu/cpu_map.xml +++ b/src/cpu/cpu_map.xml @@ -327,6 +327,11 @@ <cpuid function='0x00000007' ebx='0x00100000'/> </feature> +  + <feature name='invtsc'> + <cpuid function='0x80000007' edx='0x00000100'/> + </feature> +  <model name='486'> <feature name='fpu'/> diff --git a/src/qemu/qemu_migration.c b/src/qemu/qemu_migration.c index f0df1a6..7504a38 100644 --- a/src/qemu/qemu_migration.c +++ b/src/qemu/qemu_migration.c @@ -1513,6 +1513,20 @@ qemuMigrationIsAllowed(virQEMUDriverPtr driver, virDomainObjPtr vm, return false; } + for (i = 0; i < def->cpu->nfeatures; i++) { + virCPUFeatureDefPtr feature = &def->cpu->features[i]; + + if (feature->policy != VIR_CPU_FEATURE_REQUIRE) + continue; + + if (STREQ(feature->name, "invtsc")) { + virReportError(VIR_ERR_OPERATION_INVALID, + _("domain has CPU feature: %s"), + feature->name); + return false; + } + } + return true; } diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index a83780f..0824afe 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -3568,6 +3568,7 @@ qemuProcessVerifyGuestCPU(virQEMUDriverPtr driver, virDomainObjPtr vm) qemuDomainObjPrivatePtr priv = vm->privateData; int rc; bool ret = false; + size_t i; switch (arch) { case VIR_ARCH_I686: @@ -3590,6 +3591,20 @@ qemuProcessVerifyGuestCPU(virQEMUDriverPtr driver, virDomainObjPtr vm) goto cleanup; } } + + for (i = 0; i < def->cpu->nfeatures; i++) { + virCPUFeatureDefPtr feature = &def->cpu->features[i]; + + if (feature->policy != VIR_CPU_FEATURE_REQUIRE) + continue; + + if (STREQ(feature->name, "invtsc") && + !cpuHasFeature(guestcpu, feature->name)) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("host doesn't support invariant TSC")); + goto cleanup; + } + } break; default: -- 1.8.3.2

[libvirt] [PATCH 00/12] Couple of host info getting improvements

[libvirt] [PATCH] Increase the size of REMOTE_MIGRATE_COOKIE_MAX to REMOTE_STRING_MAX

by Shivaprasad G Bhat

During guest migration, if the domain xml is bigger than 16384 which is easily possible for a guest with good number of disks, message encode fails for xdr_remote_domain_migrate_perform3_ret(). So, Increase the COOKIE_MAX to STRING_MAX value.

[libvirt] storage conf: Add key-value options to storage pools

by Wido den Hollander

This series of patches adds the ability to pass down options to the storage pool drivers. In the case of NFS users can specify mount options and in the case of RBD users can specify options for librados to influence some behavior. All options and values are checked on input validity to prevent injection of malicious commands. -- Wido den Hollander

[libvirt] [PATCHv3 00/36] Network backed backing chains and block jobs

by Peter Krempa

First 7 patches of v2 are already pushed. First ~6 patches of this series were already ACKed, but can't be pushed due to the freeze and rebase conflicts of changing order of the patches. Thus I'm reposting them. Peter Krempa (36): storage: backend: Add unique id retrieval API storage: Add API to check accessibility of storage volumes storage: Move virStorageFileGetMetadata to the storage driver storage: Determine the local storage type right away test: storage: Initialize storage source to correct type storage: backend: Add possibility to suppress errors from backend lookup storage: Switch metadata crawler to use storage driver to get unique path storage: Switch metadata crawler to use storage driver to read headers storage: Switch metadata crawler to use storage driver file access check storage: Add infrastructure to parse remote network backing names storage: Change to new backing store parser storage: Traverse backing chains of network disks util: string: Return element count from virStringSplit util: string: Add helper to free non-NULL terminated string arrays util: storagefile: Add helper to resolve "../", "./" and "////" in paths util: storage: Add helper to resolve relative path difference util: storagefile: Add canonicalization to virStorageFileSimplifyPath storage: gluster: Add backend to return unique storage file path qemu: json: Add format strings for optional command arguments tests: storagetest: Unify and reformat storage chain format string tests: virstoragetest: Remove "expBackingStore" field tests: virstoragetest: Fix output when hitting errors storage: Store relative path only for relatively backed storage tests: virstoragetest: Remove now unused pathAbs util: storage: Remove now redundant backingRelative from virStorageSource tests: virstoragetest: Don't test relative start of backing chains tests: virstoragetest: Remove unneeded relative test plumbing storage: Don't canonicalize paths unnecessarily storage: Don't store parent directory of an image explicitly qemu: monitor: Add argument for specifying backing name for block commit qemu: monitor: Add support for backing name specification for block-stream lib: Introduce flag VIR_DOMAIN_BLOCK_COMMIT_RELATIVE lib: Introduce flag VIR_DOMAIN_BLOCK_REBASE_RELATIVE qemu: caps: Add capability for change-backing-file command qemu: Add support for networked disks for block commit qemu: Add support for networked disks for block pull/block rebase cfg.mk | 2 +- include/libvirt/libvirt.h.in | 6 + src/Makefile.am | 2 + src/libvirt_private.syms | 7 +- src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_domain.c | 10 +- src/qemu/qemu_driver.c | 79 +++- src/qemu/qemu_migration.c | 6 +- src/qemu/qemu_monitor.c | 21 +- src/qemu/qemu_monitor.h | 4 +- src/qemu/qemu_monitor_json.c | 139 ++++-- src/qemu/qemu_monitor_json.h | 2 + src/security/virt-aa-helper.c | 2 + src/storage/storage_backend.c | 16 +- src/storage/storage_backend.h | 12 +- src/storage/storage_backend_fs.c | 62 +++ src/storage/storage_backend_gluster.c | 92 ++++ src/storage/storage_driver.c | 212 +++++++++ src/storage/storage_driver.h | 7 + src/util/virstoragefile.c | 822 +++++++++++++++++++++++----------- src/util/virstoragefile.h | 34 +- src/util/virstring.c | 44 +- src/util/virstring.h | 7 + tests/Makefile.am | 8 +- tests/qemumonitorjsontest.c | 2 +- tests/virstoragetest.c | 491 +++++++++++++------- tests/virstringtest.c | 14 +- tools/virsh-domain.c | 29 +- tools/virsh.pod | 10 +- 30 files changed, 1633 insertions(+), 512 deletions(-) -- 1.9.3
