[libvirt] Questions on libvirt storage internals
by Shehjar Tikoo 12 Jul '11

12 Jul '11

Hi All I am working on integrating GlusterFS with OpenStack so that VM volumes can be placed on shared GlusterFS volumes. I would highly appreciate if you please help me find the answers to some questions: 1. Whats the difference between a storage driver and a storage backend driver? 2. Why does virDomainAttachDevice code path call the corresponding domainAttach function in the hypervisor driver and not the volume or pool creation method if a disk is being attached? Does it assume that the volume has already been created before this call? 3. Which part of libvirtd source handles receiving messages from the libvirt client? Thanks -Shehjar

[libvirt] [PATCH] Add domain type checking
by Matthias Bolte 12 Jul '11

12 Jul '11

The drivers were accepting domain configs without checking if those were actually meant for them. For example the LXC driver happily accepts configs with type QEMU. For convenience add an optional check for the domain type for the virDomainDefParse* functions. It's optional because in some places virDomainDefParse* is used to parse a config without caring about it's type. Also the QEMU driver has to accept 4 different types and does this checking own it's own. --- src/conf/domain_conf.c | 48 ++++++++++++++++++++++++++++++---------- src/conf/domain_conf.h | 5 ++++ src/esx/esx_driver.c | 5 ++- src/libxl/libxl_driver.c | 14 ++++++----- src/lxc/lxc_controller.c | 2 +- src/lxc/lxc_driver.c | 13 ++++++----- src/openvz/openvz_driver.c | 2 + src/phyp/phyp_driver.c | 1 + src/qemu/qemu_domain.c | 26 ++++++++++++++++++++- src/qemu/qemu_domain.h | 8 +++++- src/qemu/qemu_driver.c | 34 ++++++++++++++++++++-------- src/qemu/qemu_migration.c | 12 +++++----- src/security/virt-aa-helper.c | 2 +- src/test/test_driver.c | 11 ++++++-- src/uml/uml_driver.c | 8 +++--- src/vbox/vbox_tmpl.c | 2 +- src/vmware/vmware_driver.c | 2 + src/xen/xen_driver.c | 5 +-- src/xen/xend_internal.c | 5 ++- src/xen/xm_internal.c | 2 +- src/xenapi/xenapi_driver.c | 7 ++++- tests/define-dev-segfault | 2 +- tests/qemuxml2argvtest.c | 11 ++++++++- tests/qemuxml2xmltest.c | 13 +++++++++- tests/xmconfigtest.c | 2 +- tests/xml2sexprtest.c | 2 +- tests/xml2vmxtest.c | 3 +- 27 files changed, 176 insertions(+), 71 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 7bcdcaf..69200ee 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -1257,7 +1257,7 @@ virDomainObjSetDefTransient(virCapsPtr caps, if (!(xml = virDomainDefFormat(domain->def, VIR_DOMAIN_XML_WRITE_FLAGS))) goto out;

I'm seeing: /usr/bin/ld: libvirt_lxc-domain_conf.o: undefined reference to symbol 'log2@@GLIBC_2.2.5' when building the git HEAD just now.

[libvirt] [RFC] exporting KVM host power saving capabilities through libvirt
by Vaidyanathan Srinivasan 11 Jul '11

11 Jul '11

Hi, Linux host systems running KVM support various power management capabilities. Most of the features like DVFS and sleep states can be independently exploited by the host system itself based on system utilisation subject to policies set by the administrator. However, system-wide low power states like S3 and S4 would require external communication and interaction with the systems management stack in order to be used. The first steps in this direction would be to allow systems management stack to discover host power saving capabilities like S3 and S4 along with various other host CPU capabilities. Libvirt seems to be the main glue layer between the platform and the systems-management stack. Adding host power savings capabilities as part of libvirt host discovery mechanism seems to be one possible approach without addition of any new APIs or agents. libvirt has virConnectGetCapabilities() that would export an XML file describing the capabilities of the host platform and guest features. KVM hypervisor's capability to support S3 can be exported as a host feature in the XML as follows: <host> <uuid>94a3492f-2635-2491-8c87-8de976fad119</uuid> <cpu> <arch>x86_64</arch> <features> <<<=== New host feature fields <S3/> <S4/> </features> <model>Westmere</model> <vendor>Intel</vendor> <topology sockets='1' cores='2' threads='2'/> <feature name='rdtscp'/> <feature name='xtpr'/> <feature name='tm2'/> <feature name='est'/> <feature name='vmx'/> <<<= These are host CPU features System management software that works through libvirt, already queries this capabilities XML file and hence no new API is needed. As simple discovery mechanism can be added to libvirt as follows: Index: libvirt-0.9.0/src/qemu/qemu_capabilities.c =================================================================== --- libvirt-0.9.0.orig/src/qemu/qemu_capabilities.c +++ libvirt-0.9.0/src/qemu/qemu_capabilities.c @@ -738,6 +738,14 @@ virCapsPtr qemuCapsInit(virCapsPtr old_c virCapabilitiesAddHostMigrateTransport(caps, "tcp"); + /* Add host energy management host capabilities */ + + /* if "pm-is-supported --suspend" == 0 */ + virCapabilitiesAddHostFeature(caps, "S3"); + + /* if "pm-is-supported --hibernate" == 0 */ + virCapabilitiesAddHostFeature(caps, "S4"); + /* First the pure HVM guests */ for (i = 0 ; i < ARRAY_CARDINALITY(arch_info_hvm) ; i++) if (qemuCapsInitGuest(caps, old_caps, Please let me know your comments, I will code a working prototype shortly and post for review/discussion.

[libvirt] [PATCH] Skip some xen tests if xend is not running
by Jim Fehlig 11 Jul '11

11 Jul '11

Currently, the xen statstest and reconnect tests are only compiled if xend is running. Compile them unconditionally if xen headers are present, but skip the tests at runtime if xend is not running.
