[libvirt] [PATCH v3] security: Rename DomainSetDirLabel to DomainSetPathLabel
by Martin Kletzander 18 Apr '16

18 Apr '16

[libvirt] [PATCH v4 0/2] persistent live migration with specified XML
by Dmitry Andreev 18 Apr '16

18 Apr '16

v4: wrong param name in commit msg v3: - use shorter name for param and rename args - move qemuMigrationCookieAddPersistent out from qemuMigrationBakeCookie - rebase to master v2: reimplemented with new migration param Libvirt doesn't allow to specify destination persistent domain configuration. VIR_MIGRATE_PARAM_DEST_XML migration param is used for active configuration and persistent configuration is taken from source domain. The problem is mentioned in this bug: https://bugzilla.redhat.com/show_bug.cgi?id=835300 This patch-set introduces new migration param VIR_MIGRATE_PARAM_PERSIST_XML and implements its support in qemu driver.

[libvirt] [PATCH] qemu: reject min_guarantee at parse time
by Cole Robinson 18 Apr '16

18 Apr '16

min_guarantee isn't implemented for qemu, and an explicit check was added in june 2014 to reject the VM at qemu startup time. It's a weird place to do XML validation, so move it to the post parse area where we have similar checks. Also drop a validation check against min_guarantee in the command line building; it will never see min_guarantee there. --- src/qemu/qemu_command.c | 1 - src/qemu/qemu_domain.c | 7 +++++++ src/qemu/qemu_process.c | 7 ------- 3 files changed, 7 insertions(+), 8 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 26c19ff..2fb967a 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -9143,7 +9143,6 @@ qemuBuildCommandLineValidate(virQEMUDriverPtr driver, if (virMemoryLimitIsSet(def->mem.hard_limit) || virMemoryLimitIsSet(def->mem.soft_limit) || - def->mem.min_guarantee || virMemoryLimitIsSet(def->mem.swap_hard_limit)) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", _("Memory tuning is not available in session mode")); diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index 73187ce..f5fafc8 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -1690,6 +1690,13 @@ qemuDomainDefPostParse(virDomainDefPtr def, return ret; } + if (def->mem.min_guarantee) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("Parameter 'min_guarantee' " + "not supported by QEMU.")); + return -1; + } + if (def->os.loader && def->os.loader->type == VIR_DOMAIN_LOADER_TYPE_PFLASH && def->os.loader->readonly == VIR_TRISTATE_SWITCH_ON && diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 81d86c2..387aff5 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -4550,13 +4550,6 @@ qemuProcessStartValidate(virQEMUDriverPtr driver, virDomainDefCheckDuplicateDiskInfo(vm->def) < 0) return -1; - if (vm->def->mem.min_guarantee) { - virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", - _("Parameter 'min_guarantee' " - "not supported by QEMU.")); - return -1; - } - VIR_DEBUG("Checking for any possible (non-fatal) issues"); /* -- 2.7.3

[libvirt] [libvirt-glib v2] spec: Add verification of the tarball GPG signature

[libvirt] [PATCH] tests: Fix syntax in iSCSI auth/secret tests
by John Ferlan 18 Apr '16

18 Apr '16

While working on the tests for the secret initialization vector, I found that the existing iSCSI tests were lacking in how they defined the IQN. Many had IQN's of just 'iqn.1992-01.com.example' for one disk while using 'iqn.1992-01.com.example/1' for the second disk (same for hostdevs - guess how they were copied/generated). Typically (and documented this way), IQN's would include be of the form 'iqn.1992-01.com.example:storage/1' indicating an IQN using "storage" for naming authority specific string and "/1" for the iSCSI LUN. So modify the input XML's to use the more proper format - this of course has a ripple effect on the output XML and the args. Also note that the "%3A" is generated by the virURIFormat/xmlSaveUri to represent the colon.

[libvirt] [PATCH] ZFS: Support sparse volumes
by Richard Laager 17 Apr '16

17 Apr '16

By default, `zfs create -V ...` reserves space for the entire volsize, plus some extra (which attempts to account for overhead). If `zfs create -s -V ...` is used instead, zvols are (fully) sparse. A middle ground (partial allocation) can be achieved with `zfs create -s -o refreservation=... -V ...`. Both libvirt and ZFS support this approach, so the ZFS storage backend should support it.

Look at the code for createVport() - see the 'parent_hoststr' description. When you did a pool-{create|define} for the "poolhba_name", you provided some XML which would search the existing 'scsi_host#' for one that's capable of supporting a vHBA. What that create is supposed to do (at least it does it on the systems I used) is create another 'scsi_host#'. That scsi_host# is then the vHBA - it's *parent* is supposed to be 'scsi_host2' - see my example. On your host perhaps scsi_host3 or scsi_host4. Do either one of those two have the wwnn/wwpn that's in your poolhba_name: <adapter type='fc_host' managed='yes' wwnn='20000120fa8f1271' wwpn='10000090fa8f1271'/> I'm really not quite sure what's happening on your host/environment. Perhaps you could follow how createVport generates things and report back. You can always 'create' another vHBA using a different wwnn/wwpn John
