[libvirt] [PATCH] lxc: Don't crash by forgetting to ref transient domains
by Martin Kletzander 22 Jul '16

22 Jul '16

So commit 306b3a8504 tried mimicking behaviour of commit 540c339a25, but added a virObjectRef(vm) only after virDomainObjListAdd() in lxcDomainDefineXMLFlags() and not in lxcDomainCreateXMLWithFiles(). That way undefining a domain that was started with different XML than defined will leave the domain object in a state with not enough references to then remove it. Hence any lxcDomainDestroyFlags() called afterwards crashes the daemon.

[libvirt] [PATCH RFC 0/5] lxc: Add save/restore support to lxc driver
by Katerina Koukiou 22 Jul '16

22 Jul '16

This patch series adds support for saving an running lxc domain's state into files with lxcDomainSave and restore afterwards from files with lxcDomainRestore. Usage: virsh save [domain-name] [domain-id or domain-uuid] [directory name] I use CRIU tool (https://criu.org/Main_Page) that offers checkpoint/restore functionality for containers in userspace. For the time, I have tried successfully the C/R procedure for simple sh containers and OS containers. I'll mention some notes/issues here: *I have working C/R only for non systemd hosts (on systemd host I was facing problems with CRIU). *I have not done anything for container networking. Thats should be done with --veth-pair IN=OUT option in CRIU. *In new distros, where efivars mountpoint exists, CRIU dump fails. *The only tty restored is /dev/tty1. I'll fix this in another patch, to allow more ttys. *Currently for things to work, I have slightly modified criu source. That is in criu master I have the following diff: diff --git a/criu/tty.c b/criu/tty.c index 302dd54..2226484 100644 --- a/criu/tty.c +++ b/criu/tty.c @@ -1394,8 +1394,10 @@ static int verify_info(struct tty_info *info) */ if (term_opts_missing_any(info)) { if (tty_is_master(info)) { + /* pr_err("Corrupted master peer %x\n", info->tfe->id); return -1; + */ } else if (!term_opts_missing_all(info)) { pr_err("Corrupted slave peer %x\n", info->tfe->id); return -1; Lastly, I have ready a patch that adds support for migration but I wait for feedback on this series, and I'll send the migration one later. Anyway, any comments here are more than welcome. ps: That is a work in terms of my GSoC 2016 project.

[libvirt] [PATCH v2] qemuhotplugtest: Add tests for ccw devices
by Tomasz Flendrich 21 Jul '16

21 Jul '16

There's a plan to rework the address handling, so testcases that verify hotplugging ccw devices will help in avoiding regression. In this commit, some device files are duplicated because of the way qemuhotplug.c calculates the expected xml filenames. I plan on changing that to explicitly stating the basis domain xml, the device xml, and the expected xml. --- Changes in v2: * the target dev in the first attachment is changed from vde2 to hda, so the device is now something hopefully valid and there are no duplicated aliases * the target dev in the second attachment is changed from vde to hdb, so now it's different than the device that was previously under this address. I did it to make sure that it's a completely new device. tests/qemuhotplugtest.c | 37 +++++++++++ .../qemuhotplug-ccw-virtio-1-explicit.xml | 8 +++ .../qemuhotplug-ccw-virtio-1-reverse.xml | 7 +++ .../qemuhotplug-ccw-virtio-2-explicit.xml | 8 +++ .../qemuhotplug-ccw-virtio-2.xml | 8 +++ .../qemuhotplug-ccw-virtio.xml | 8 +++ .../qemuhotplug-base-ccw-live+ccw-virtio.xml | 63 +++++++++++++++++++ ...ive-with-2-ccw-virtio+ccw-virtio-1-explicit.xml | 73 ++++++++++++++++++++++ ...live-with-2-ccw-virtio+ccw-virtio-1-reverse.xml | 73 ++++++++++++++++++++++ ...qemuhotplug-base-ccw-live-with-2-ccw-virtio.xml | 63 +++++++++++++++++++ ...-live-with-ccw-virtio+ccw-virtio-2-explicit.xml | 73 ++++++++++++++++++++++ ...-base-ccw-live-with-ccw-virtio+ccw-virtio-2.xml | 73 ++++++++++++++++++++++ .../qemuhotplug-base-ccw-live-with-ccw-virtio.xml | 63 +++++++++++++++++++ .../qemuhotplug-base-ccw-live.xml | 53 ++++++++++++++++ 14 files changed, 610 insertions(+) create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-1-explicit.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-1-reverse.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-2-explicit.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-2.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live+ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-2-ccw-virtio+ccw-virtio-1-explicit.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-2-ccw-virtio+ccw-virtio-1-reverse.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-2-ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-ccw-virtio+ccw-virtio-2-explicit.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-ccw-virtio+ccw-virtio-2.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live.xml diff --git a/tests/qemuhotplugtest.c b/tests/qemuhotplugtest.c index f2e7567..0a5f068 100644 --- a/tests/qemuhotplugtest.c +++ b/tests/qemuhotplugtest.c @@ -73,6 +73,7 @@ qemuHotplugCreateObjects(virDomainXMLOptionPtr xmlopt, virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_VIRTIO_SCSI); virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_DEVICE_USB_STORAGE); + virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_VIRTIO_CCW); if (event) virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_DEVICE_DEL_EVENT); @@ -523,6 +524,42 @@ mymain(void) "device_del", QMP_OK, "chardev-remove", QMP_OK); + DO_TEST_ATTACH("base-ccw-live", "ccw-virtio", false, true, + "human-monitor-command", HMP("OK\\r\\n"), + "device_add", QMP_OK); + DO_TEST_DETACH("base-ccw-live", "ccw-virtio", false, false, + "device_del", QMP_OK, + "human-monitor-command", HMP("")); + + DO_TEST_ATTACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2", false, true, + "human-monitor-command", HMP("OK\\r\\n"), + "device_add", QMP_OK); + + DO_TEST_DETACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2", false, false, + "device_del", QMP_OK, + "human-monitor-command", HMP("")); + + DO_TEST_ATTACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2-explicit", false, true, + "human-monitor-command", HMP("OK\\r\\n"), + "device_add", QMP_OK); + + DO_TEST_DETACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2-explicit", false, false, + "device_del", QMP_OK, + "human-monitor-command", HMP("")); + + /* Attach a second device, then detach the first one.

[libvirt] [RFC PATCH 0/2] nodeinfo: PPC64: Fix topology and siblings info on capabilities and nodeinfo
by Shivaprasad G Bhat 21 Jul '16

21 Jul '16

The nodeinfo output was fixed earlier to reflect the actual cpus available in KVM mode on PPC64. The earlier fixes covered the aspect of not making a host look overcommitted when its not. The current fixes are aimed at helping the users make better decisions on the kind of guest cpu topology that can be supported on the given sucore_per_core setting of KVM host and also hint the way to pin the guest vcpus efficiently. I am planning to add some test cases once the approach is accepted. With respect to Patch 2: The second patch adds a new element to the cpus tag and I need your inputs on if that is okay. Also if there is a better way. I am not sure if the existing clients have RNG checks that might fail with the approach. Or if the checks are not enoforced on the elements but only on the tags. With my approach if the rng checks pass, the new element "capacity" even if ignored by many clients would have no impact except for PPC64. To the extent I looked at code, the siblings changes dont affect existing libvirt functionality. Please do let me know otherwise. --- Shivaprasad G Bhat (2): nodeinfo: Reflect guest usable host topology on PPC64 Introduce capacity to virCapsHostNUMACellCPU to help vcpu pinning decisions src/conf/capabilities.c | 3 + src/conf/capabilities.h | 1 src/nodeinfo.c | 51 ++++++++++++++++++++++-- tests/vircaps2xmldata/vircaps-basic-4-4-2G.xml | 32 ++++++++------- tests/vircaps2xmltest.c | 1 5 files changed, 67 insertions(+), 21 deletions(-) -- Signature

[libvirt] [PATCH] Remove code duplication in domain_addr.c
by Tomasz Flendrich 21 Jul '16

21 Jul '16

Two functions, virDomainValidateDevicePCISlotsQ35 and virDomainValidateDevicePCISlotsPIIX3, had almost exactly the same code for verifying the PCI address of the primary video device. The only difference between them was the slot number. To avoid code duplication, I moved it to a new function: virDomainValidateVideoDevice. --- src/conf/domain_addr.c | 218 +++++++++++++++++++++---------------------------- 1 file changed, 94 insertions(+), 124 deletions(-) diff --git a/src/conf/domain_addr.c b/src/conf/domain_addr.c index 7abe44c..9a6f977 100644 --- a/src/conf/domain_addr.c +++ b/src/conf/domain_addr.c @@ -1391,6 +1391,82 @@ virDomainMachineIsI440FX(const virDomainDef *def) static int +virDomainValidateVideoDevice(virDomainDefPtr def, + virDomainPCIAddressSetPtr addrs, + virDomainPCIConnectFlags flags, + bool videoPrimaryEnabled, + unsigned int slot) +{ + int ret = -1;

[libvirt] RFC: disk tray opened event and changing media API cooperation
by Nikolay Shirokovskiy 21 Jul '16

21 Jul '16

Hi, all. I want to remove media if disk is ejected from guest. I can leverage tray opened event for it but this event generated if i change media thru API call too. Thus I can't just remove media on any such event. However it would be possible if libvirt do not propagate tray opened event that originates from qemuDomainUpdateDeviceFlags actions. On this way we need also to close tray back if it was originally closed so state visible to client is in sync with actual. I can imagine other cases when closing tray at the end of qemuDomainUpdateDeviceFlags will be useful. Say implementing a kind of changer in mgmt layer so that if guest ejects disk mgmt insert next media from some playlist. In this case tray should be closed so that guest will see that media is changed. In short I suggest: 1. close tray at the end of chaning/ejecting media 2. if tray is opened during the operation than mask this event from client Nikolay

I'm seeing this compilation warning on Fedora 24, with wireshark-devel-2.1.0-3.fc24.x86_64 which has the header file fix that was previously breaking compilation: CC wireshark/src/wireshark_src_libvirt_la-packet-libvirt.lo CC wireshark/src/wireshark_src_libvirt_la-plugin.lo CCLD nss/libnss_libvirt.la wireshark/src/packet-libvirt.c: In function 'proto_reg_handoff_libvirt': wireshark/src/packet-libvirt.c:548:46: warning: passing argument 1 of 'create_dissector_handle' from incompatible pointer type [-Wincompatible-pointer-types] libvirt_handle = create_dissector_handle(dissect_libvirt, proto_libvirt); ^~~~~~~~~~~~~~~ In file included from wireshark/src/packet-libvirt.c:28:0: /usr/include/wireshark/epan/packet.h:525:68: note: expected 'dissector_t {aka int (*)(struct tvbuff *, struct _packet_info *, struct _proto_node *, void *)}' but argument is of type 'void (*)(tvbuff_t *, packet_info *, proto_tree *) {aka void (*)(struct tvbuff *, struct _packet_info *, struct _proto_node *)}' WS_DLL_PUBLIC dissector_handle_t create_dissector_handle(dissector_t dissector, I can't even find the definition of dissect_libvirt so I assume there's some weird magic going on here... Thanks, Cole
