[libvirt] [PATCH v8 0/4] Introduce API to query IP addresses for given domain
by Nehal J Wani 06 Mar '15

06 Mar '15

This feature has been requested for a very long time. Since qemu guest agent and leaseshelper give us reliable results, now the wait is over. The RFC was first proposed by Michal Privoznik: http://www.redhat.com/archives/libvir-list/2012-February/msg00437.html A patch was submitted, using structs: https://www.redhat.com/archives/libvir-list/2012-June/msg00220.html Another patch was submitted, using XML: https://www.redhat.com/archives/libvir-list/2012-June/msg00904.html Neither of the patches were accepted, probably due to lack of extensibility and usability. Hence, we thought of using virTypedParameters for reporting list of interfaces along with their MAC address and IP addresses. The RFC can be found here: https://www.redhat.com/archives/libvir-list/2013-July/msg00084.html The idea of extensibility was rejected and rendered out of scope of libvirt. Hence, we were back to structs. This API is called virDomainInterfaceAddresses which returns a dynamically allocated array of virDomainInterface struct. The great disadvantage is once this gets released, it's written in stone and we cannot change or add an item into it. The virsh CLI supports two methods: * Return information (list of all associated interfaces with MAC address and IP addresses) of all of the domain interfaces by default (if no interface name is provided) * Return information for the specified interface (if an interface name is provided) v8: * qemuDomainInterfaceAddresses: redo logic related to flags * Make sure that NIC(s) on guest is/are using libvirt virtual network before querying leaseshelper * domifaddr: change --network option from VSH_OT_DATA to VSH_OT_STRING v7: * Enable support for DHCP lease file parsing method * http://www.redhat.com/archives/libvir-list/2014-December/msg00866.html v6: * Inclusion of flags, readonly check for guest agent connection * Correction of memory leaks, other small nits. * https://www.redhat.com/archives/libvir-list/2013-September/msg00350.html v5: * s/virDomainInterfacesAddresses/virDomainInterfaceAddresses. * Case for IP aliasing handled using virHashTable. * New test cases added, involving multiple and 0 IP addresse(s) per interface. * IP prefix changed from int to unsigned int. * Changes to practice libvirt habits. * https://www.redhat.com/archives/libvir-list/2013-September/msg00003.html v4: * Various style nits, indentation errors, memory leaks fixed. * https://www.redhat.com/archives/libvir-list/2013-August/msg01265.html v3: * Upper bounds to number of interfaces and addresses per interface introduced. * Change from array of structs to array of pointers * ifaces_count moved from function argument to return value * Changes in variable names * Test cases added for qemuAgentGetInterfaces. * https://www.redhat.com/archives/libvir-list/2013-August/msg01215.html v2: * Logical errors, memory leaks and few other errors fixed. * https://www.redhat.com/archives/libvir-list/2013-August/msg00631.html v1: * http://www.redhat.com/archives/libvir-list/2013-July/msg01553.html Nehal J Wani (4): domifaddr: Implement the public APIs domifaddr: Implement the remote protocol domifaddr: Implement the API for qemu domifaddr: Add virsh support daemon/remote.c | 134 ++++++++++++++++++++++++++ include/libvirt/libvirt-domain.h | 27 ++++++ src/driver-hypervisor.h | 5 + src/libvirt-domain.c | 129 +++++++++++++++++++++++++ src/libvirt_public.syms | 6 ++ src/qemu/qemu_agent.c | 202 +++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_agent.h | 4 + src/qemu/qemu_driver.c | 173 +++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 100 +++++++++++++++++++ src/remote/remote_protocol.x | 36 ++++++- src/remote_protocol-structs | 24 +++++ tests/qemuagenttest.c | 188 ++++++++++++++++++++++++++++++++++++ tools/virsh-domain-monitor.c | 141 +++++++++++++++++++++++++++ tools/virsh.pod | 16 ++++ 14 files changed, 1184 insertions(+), 1 deletion(-) -- 2.1.0

[libvirt] direct device assignment
by Raymond Durand 05 Mar '15

05 Mar '15

I read this in the context of direct device assignment: "All of the guest's memory must kept permanently in memory. This is because the guest may program the device with any address in its address space and the hypervisor has no way of handling a DMA page fault" is it still true? Thanks, Regards,

[libvirt] memory ballooning and nova
by Raymond Durand 05 Mar '15

Is Libvirt memory ballooning managed by nova in OpenStack Juno? Is Libvirt memory ballooning independent from the OpenStack "RAM allocation ratio"? and allow a VM to expand (page out) even though the overall RAM allocation ratio is already at his maximum? Thanks, Regards,

v2 here: http://www.redhat.com/archives/libvir-list/2015-February/msg00562.html Changes over v2: Patches 1-4 * Add "resources" and "nresources" in order to return the resources that are using an IOThread * Fixed memory leak - neglected to free the qemuMonitorIOThreadsInfoPtr 'iothreads' in patch 3 Patches 5-9 (NEW) * Patches 5 & 6 implement the API/remote protocol for virDomainSetIOThreads * Patch 7 implements a couple of helper function - copies of existing vcpupin functions * Patch 8 implements the qemu backend qemuDomainSetIOThreads in order to allow setting IOThread pin data either for live or config. Heavily lifted from existing vcpu code * Patch 9 implements the virsh command options in order to set the pinning on a specific thread. As a side effect/benefit one can now display just one IOThread if so desired.

[libvirt] [PATCH] domain_conf: Format <pvpanic/> without address correctly
by Michal Privoznik 05 Mar '15

05 Mar '15

We have something like pvpanic device. However, in some cases it does not have any address assigned, in which case we produce this ugly XML (still valid though): <devices> <emulator>/usr/bin/qemu</emulator> ... <panic> </panic> </devices> Lets format "<pvpanic/>" instead.

[libvirt] [PATCH 0/3] unify memtune value representation in libvirt
by Pavel Hrdina 05 Mar '15

05 Mar '15

The first patch rewrites virsh memtune command to accept 0 as valid value instead of ignoring it. In the second patch I'll introduce a simple helper to crop the *_limit values to VIR_DOMAIN_MEMORY_PARAM_UNLIMITED as its used several times while reading values from cgroups. The last patch actually changes the internal representation of unlimited memtune settings. More detailed description is in commit message. My motivation to change it completely is to prevent future bugs with those limits.

[libvirt] [PATCH v2] qemu: Allow spaces in disk serial
by Michal Privoznik 05 Mar '15

05 Mar '15

https://bugzilla.redhat.com/show_bug.cgi?id=1195660 There's been a bug report appearing on the qemu-devel list, that libvirt is unable to pass spaces in disk serial number [1]. Not only our RNG schema forbids that, the code is not prepared either. However, with a bit of escaping (if needed) we can allow spaces there. 1: https://lists.gnu.org/archive/html/qemu-devel/2015-02/msg04041.html Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- diff to v1: - Switch from virBufferEscapeShell to virBufferEscape docs/schemas/domaincommon.rng | 2 +- src/qemu/qemu_command.c | 5 ++-- .../qemuxml2argvdata/qemuxml2argv-disk-serial.args | 7 ++++++ .../qemuxml2argvdata/qemuxml2argv-disk-serial.xml | 27 ++++++++++++++++++++++ tests/qemuxml2argvtest.c | 5 ++++ 5 files changed, 43 insertions(+), 3 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index f41ca43..09bd921 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -5067,7 +5067,7 @@ </define> <define name="diskSerial"> <data type="string"> - <param name="pattern">[A-Za-z0-9_\.\+\-]+</param> + <param name="pattern">[A-Za-z0-9_\.\+\- ]+</param> </data> </define> <define name="bridgeMode"> diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index fb3d5ab..25b6499 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -2633,7 +2633,7 @@ qemuBuildIoEventFdStr(virBufferPtr buf, } #define QEMU_SERIAL_PARAM_ACCEPTED_CHARS \ - "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_" + "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_ " static int qemuSafeSerialParamValue(const char *value) @@ -3616,7 +3616,8 @@ qemuBuildDriveStr(virConnectPtr conn, virQEMUCapsGet(qemuCaps, QEMU_CAPS_DRIVE_SERIAL)) { if (qemuSafeSerialParamValue(disk->serial) < 0) goto error; - virBufferAsprintf(&opt, ",serial=%s", disk->serial); + virBufferAddLit(&opt, ",serial="); + virBufferEscape(&opt, '\\', " ", "%s", disk->serial); } if (disk->cachemode) { diff --git a/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args new file mode 100644 index 0000000..794b94b --- /dev/null +++ b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args @@ -0,0 +1,7 @@ +LC_ALL=C PATH=/bin HOME=/home/test USER=test LOGNAME=test QEMU_AUDIO_DRV=none \ +/usr/libexec/qemu-kvm -S -M pc -cpu qemu32 -m 214 -smp 1 -nographic -nodefaults \ +-monitor unix:/tmp/test-monitor,server,nowait -no-acpi -boot c -usb \ +-drive 'file=/dev/HostVG/QEMUGuest1,if=none,\ +id=drive-ide0-0-1,serial=\ \ WD-WMAP9A966149' \ +-device ide-drive,bus=ide.0,unit=1,drive=drive-ide0-0-1,id=ide0-0-1 \ +-device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3 diff --git a/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml new file mode 100644 index 0000000..0fe75f3 --- /dev/null +++ b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml @@ -0,0 +1,27 @@ +<domain type='kvm'> + <name>QEMUGuest1</name> + <uuid>c7a5fdbd-edaf-9455-926a-d65c16db1809</uuid> + <memory unit='KiB'>219136</memory> + <currentMemory unit='KiB'>219136</currentMemory> + <vcpu placement='static'>1</vcpu> + <os> + <type arch='i686' machine='pc'>hvm</type> + <boot dev='hd'/> + </os> + <clock offset='utc'/> + <on_poweroff>destroy</on_poweroff> + <on_reboot>restart</on_reboot> + <on_crash>destroy</on_crash> + <devices> + <emulator>/usr/libexec/qemu-kvm</emulator> + <disk type='block' device='disk'> + <source dev='/dev/HostVG/QEMUGuest1'/> + <target dev='hda' bus='ide'/> + <serial> WD-WMAP9A966149</serial> + <address type='drive' controller='0' bus='0' target='0' unit='1'/> + </disk> + <controller type='usb' index='0'/> + <controller type='ide' index='0'/> + <memballoon model='virtio'/> + </devices> +</domain> diff --git a/tests/qemuxml2argvtest.c b/tests/qemuxml2argvtest.c index 16f325e..3032d1b 100644 --- a/tests/qemuxml2argvtest.c +++ b/tests/qemuxml2argvtest.c @@ -904,6 +904,11 @@ mymain(void) QEMU_CAPS_DEVICE, QEMU_CAPS_SCSI_BLOCK, QEMU_CAPS_VIRTIO_BLK_SG_IO, QEMU_CAPS_SCSI_LSI, QEMU_CAPS_VIRTIO_SCSI); + DO_TEST("disk-serial", + QEMU_CAPS_KVM, + QEMU_CAPS_DEVICE, + QEMU_CAPS_DRIVE, + QEMU_CAPS_DRIVE_SERIAL); DO_TEST("graphics-vnc", QEMU_CAPS_VNC); DO_TEST("graphics-vnc-socket", QEMU_CAPS_VNC); -- 2.0.5

[libvirt] [PATCH v1 00/31] Drop network driver lock
by Michal Privoznik 05 Mar '15

05 Mar '15

The patchset starts slowly, with small patches, and small changes, accelerating towards the end, with big changes. I know that network driver is not used as intensely as domain drivers, but hey, if we remove 100 lines (and substitute some others) we get fine grained locking! And cleaner code, of course. Oh, and this is meant for next release, obviously :) Michal Privoznik (31): networkLookupByUUID: Improve error message bridge_driver: Don't check network active unlocked testNetworkUpdate: Unlock network at the end networkGetNetworkAddress: Drop empty 'error' label virNetworkObjIsDuplicate: s/@doms/@nets/ virNetworkObjListFree: Accept NULL virNetworkObjListExport: Pass virNetworkObjListPtr test_driver: s/virNetworkObjList/virNetworkObjListPtr/ parallels: s/virNetworkObjList/virNetworkObjListPtr/ bridge_driver: s/virNetworkObjList/virNetworkObjListPtr/ conf: s/virNetworkFindByUUID/virNetworkObjFindByUUID/ conf: s/virNetworkFindByUUID/virNetworkObjFindByUUID/ network_conf: Introduce virNetworkObjListForEach network_conf: Introduce virNetworkObjListGetNames network_conf: Introduce virNetworkObjListNumOfNetworks bridge_driver: Adapt to new virNetworkObjList accessors test_driver: Adapt to new virNetworkObjList accessors parallels_network: Adapt to new virNetworkObjList accessors network_conf: Turn virNetworkObjList into virObject network_conf: Turn struct _virNetworkObjList private network_conf: Make virNetworkObj actually virObject virNetworkObjList: Derive from virObjectLockableClass network_conf: Introduce virNetworkObjEndAPI bridge_driver: Use virNetworkObjEndAPI test_driver: Use virNetworkObjEndAPI parallels_network: Use virNetworkObjEndAPI virNetworkObjListPtr: Make APIs self-locking virNetworkObjFindBy*: Return an reference to found object bridge_driver: Drop networkDriverLock() from almost everywhere test_driver: Drop testDriverLock() from almost everywhere parallels_network: Drop parallelsDriverLock() from everywhere. cfg.mk | 3 - src/conf/network_conf.c | 372 +++++++++++++++++++------- src/conf/network_conf.h | 51 ++-- src/libvirt_private.syms | 14 +- src/network/bridge_driver.c | 502 ++++++++++++++--------------------- src/network/bridge_driver_platform.h | 2 +- src/parallels/parallels_driver.c | 5 +- src/parallels/parallels_network.c | 144 +++------- src/parallels/parallels_utils.h | 2 +- src/test/test_driver.c | 223 ++++------------ tests/networkxml2conftest.c | 4 +- tests/objectlocking.ml | 2 - 12 files changed, 612 insertions(+), 712 deletions(-) -- 2.0.5

[libvirt] [PATCH v2] qemu: snapshot: remove the redundant 'if' check

05 Mar '15

When the domain's source disk type is network, if source protocol is rbd or sheepdog, the 'if().. break' will end the current case, which lead to miss check the driver type is raw or qcow2. Libvirt will allow to create internal snapshot for a running domain with raw format disk which based on rbd storage.
