[libvirt] [PATCH] domtop: Properly free cpu status
by Michal Privoznik 20 Apr '15

20 Apr '15

So, in the example the cpu stats are collected within a function called do_top. At the beginning of the function we ask the daemon for how much vCPUs can we get stats, and how many stats for a vCPU can we get. This is because it's how our API works - users are required to preallocate a chunk of memory for the results. Now, at the end, we try to free the allocated array, but we are not doing it correctly. There's this virTypedParamsFree() function which gets a pointer to the array and the length of the array. However, if there was an error in getting vCPU stats we pass a negative number instead of the originally computed value. This flaw results in SIGSEGV: libvirt: QEMU Driver error : Requested operation is not valid: domain is not running ERROR do_top:333 : Unable to get cpu stats ==29201== Invalid read of size 4 ==29201== at 0x4F1DF8B: virTypedParamsClear (virtypedparam.c:1145) ==29201== by 0x4F1DFEB: virTypedParamsFree (virtypedparam.c:1165) ==29201== by 0x4023C3: do_top (domtop.c:349) ==29201== by 0x40260B: main (domtop.c:386) ==29201== Address 0x131cd7c0 is 16 bytes after a block of size 768 alloc'd ==29201== at 0x4C2C070: calloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==29201== by 0x401FF1: do_top (domtop.c:295) ==29201== by 0x40260B: main (domtop.c:386) Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- examples/domtop/domtop.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/examples/domtop/domtop.c b/examples/domtop/domtop.c index e50988e..2283994 100644 --- a/examples/domtop/domtop.c +++ b/examples/domtop/domtop.c @@ -346,8 +346,8 @@ do_top(virConnectPtr conn, ret = 0; cleanup: - virTypedParamsFree(now_params, now_nparams * max_id); - virTypedParamsFree(then_params, then_nparams * max_id); + virTypedParamsFree(now_params, nparams * max_id); + virTypedParamsFree(then_params, nparams * max_id); if (dom) virDomainFree(dom); return ret; -- 2.0.5

[libvirt] [PATCH 0/5] Add vmport feature (v3)
by Marc-André Lureau 20 Apr '15

20 Apr '15

Hi, The QEMU machine vmport option allows to set the VMWare IO port emulation. This emulation is useful for absolute pointer input when the guest has vmware input drivers, and is enabled by default for kvm. However it is unnecessary for Spice-enabled VM, since the agent already handles absolute pointer and multi-monitors. Furthermore, it prevents Spice from switching to relative input since the regular ps/2 pointer driver is replaced by the vmware driver. It is thus advised to disable vmport when using a Spice VM. This will permit the Spice client to switch from absolute to relative pointer, as it may be required for certain games or applications. The following patch series allows to configure the vmport feature. The first version sent used a domain attribute, Daniel Berrange suggested to use a feature instead. I sent a second version that didn't receive reviews. Hopefully this one will stand more chances! cheers Marc-André Lureau (5): docs: add domain vmport feature domain/conf: add VIR_DOMAIN_FEATURE_VMPORT qemu: add QEMU_CAPS_MACHINE_VMPORT_OPT qemu: add machine vmport argument tests: add machine-vmport-opt qemu test docs/formatdomain.html.in | 6 +++++ docs/schemas/domaincommon.rng | 9 +++++++ src/conf/domain_conf.c | 5 +++- src/conf/domain_conf.h | 1 + src/qemu/qemu_capabilities.c | 6 +++++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 14 +++++++++++ .../qemuxml2argv-machine-vmport-opt.args | 6 +++++ .../qemuxml2argv-machine-vmport-opt.xml | 28 ++++++++++++++++++++++ tests/qemuxml2argvtest.c | 2 ++ 10 files changed, 77 insertions(+), 1 deletion(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-machine-vmport-opt.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-machine-vmport-opt.xml -- 2.1.0

[libvirt] Building libvirt under Windows
by Pavel Fedin 20 Apr '15

20 Apr '15

Hello! I am currently building libvirt under Windows64, and i would like to ask for correct way to do it. The first thing to resolve is absence of RPC XDR library. From configure source i figured out that portablexdr library may help. I have downloaded it, but it comes with a different RPC code generator named portable-rpcgen. I managed to use it, but i had to patch both libvirt (in order to recognize this generator and handle it properly) and portable-rpcgen (in order to correctly work under Windows, as well as get rid of some crashes). Initially i wanted to upstream portablexdr fixes and emailed the author. But the author replied that he is not going to fix portablexdr because it's now deprecated, since original XDR code comes under free license now. So, i have all necessary fixes in my own fork. He suggested me to come here to ask about these things. So, guys, how do you do it ? I cannot find any rpcgen package usable under Windows (MinGW, not Cygwin). Kind regards, Pavel Fedin Expert Engineer Samsung Electronics Research center Russia

Re: [libvirt] [libvirt-php] memory overflow when using libvirt_list_networks

I did learn last night, the difference between my two systems that is relevant is that the overflow system ran Gentoo while the "working" system ran Debian. I was missing a USE flag for "virt-network" on the Gentoo machine. It is a development environment that I am attempting to create a supported configuration with, so these kinds of missing USE flags and other things are just facts of life I must accept. Unfortunately, it was kind-of difficult to get this information or even workaround it without rebuilding libvirt on the Gentoo machine, which means I won't be able to give a proper error message to users who encounter this problem as well. It's a problem in libvirt-php to overflow when requesting libvirt_networks_list on a machine without networking support compiled in. The PHP bindings should error out properly, not memory overflow and put errors in httpd log with cryptic results in the interpreter :-) I do like the PHP bindings but they appear to be lacking attention. Am I the only one using it? ;-) Kash Pande Jentu Technologies, Inc http://jentu-networks.com

[libvirt] [PATCH v4 0/9] qemu: Add quorum support to libvirt
by Matthias Gatto 20 Apr '15

20 Apr '15

The purpose of these patches is to introduce quorum for libvirt I've try to follow this proposal: http://www.redhat.com/archives/libvir-list/2014-May/msg00533.html This feature ask for 6 task: 1) Allow a _virStorageSource to contain more than one backing store. Because all the actual libvirt code use the backingStore field as a pointer and we needs want to change that, I've decide to encapsulate the backingStore field to simplifie the array manipulation. 2) Add the missing field a quorum need in _virStorageSource and the VIR_STORAGE_TYPE_QUORUM and VIR_STORAGE_FILE_QUORUM in their respectives enums. 3) Parse and format the xml Because a quorum allows to have more than one backing store at the same level we need to change virDomainDiskDefFormat and virDomainDiskDefParseXML to call virDomainDiskBackingStoreFormat and virDomainDiskBackingStoreParse in a loop. virDomainDiskBackingStoreFormat and virDomainDiskBackingStoreParse can call themself recursively in a loop because a quorum can contain another quorum 4) Add nodename We need to add nodename support in _virStorageSource because qemu use them for their child. 5) Build qemu string As for the xml, we have to call the function which create quorum recursively. But this task have the problem explained here: http://www.redhat.com/archives/libvir-list/2014-October/msg00529.html The _virStorageSource missing some informations that can be passed to a child, and therefore this version of quorum is incomplet. 6) Allow to hotplug/change a disk in a quorum This part is not present in these patches because for this task we have to use blockdev-add, and currently libvirt use device_add for hotpluging that doesn't allow to hotplug quorum childs. There is 3 way to handle this problem: 1) create a virDomainBlockDevAdd function in libvirt witch call blockdev-add. 2) use blockdev-add instead of device_add in qemuMonitorJSONAddDevice 3) write a hack which uses blockdev-add when only attaching quorum (but i'm pretty sure this solution is not the good one) V2: -Rebase on master -Add Documentation V3: -Transforme the backingStore field in virStorageSource into an array of pointer instead of a pointer -Modify virStorageSourceSetBackingStore to allow it to expand the backingStore size. V4: -Rebase on master Matthias Gatto (9): virstoragefile: Add virStorageSourceGetBackingStore virstoragefile: Always use virStorageSourceGetBackingStore to get backing store virstoragefile: Add virStorageSourceSetBackingStore virstoragefile: Always use virStorageSourceSetBackingStore to set backing store virstoragefile: change backingStore to backingStores. virstoragefile: Add quorum in virstoragefile domain_conf: Read and Write quorum config qemu: Add quorum support in qemuBuildDriveDevStr virstoragefile: Add node-name docs/formatdomain.html.in | 27 ++++- docs/schemas/domaincommon.rng | 95 +++++++++++------ docs/schemas/storagecommon.rng | 1 + docs/schemas/storagevol.rng | 1 + src/conf/domain_conf.c | 195 ++++++++++++++++++++++++++-------- src/conf/storage_conf.c | 22 ++-- src/libvirt_private.syms | 2 + src/qemu/qemu_cgroup.c | 4 +- src/qemu/qemu_command.c | 114 ++++++++++++++++++++ src/qemu/qemu_domain.c | 2 +- src/qemu/qemu_driver.c | 30 +++--- src/qemu/qemu_migration.c | 1 + src/security/security_dac.c | 2 +- src/security/security_selinux.c | 4 +- src/security/virt-aa-helper.c | 2 +- src/storage/storage_backend.c | 35 +++--- src/storage/storage_backend_fs.c | 37 ++++--- src/storage/storage_backend_gluster.c | 10 +- src/storage/storage_backend_logical.c | 15 ++- src/storage/storage_driver.c | 2 +- src/util/virstoragefile.c | 116 +++++++++++++++++--- src/util/virstoragefile.h | 13 ++- tests/virstoragetest.c | 18 ++-- 23 files changed, 573 insertions(+), 175 deletions(-) -- 1.8.3.1

[libvirt] [PATCH] rng: Forbid to validate mismatched <disk> 'device' and 'type' attributes
by Erik Skultety 20 Apr '15

20 Apr '15

According to docs, using 'lun' as a value for device attribute is only valid with disk types 'block' and 'network'. However current RNG schema also allows a combination type='file' device='lun' which results in a successfull xml validation, but fails at qemuBuildCommandLine. Besides fixing the RNG schema, this patch also adds a qemuxml2argvtest for this case. https://bugzilla.redhat.com/show_bug.cgi?id=1210669 --- docs/schemas/domaincommon.rng | 42 ++++++++++++++-------- .../qemuxml2argv-disk-device-lun-type-invalid.xml | 28 +++++++++++++++ tests/qemuxml2argvtest.c | 2 ++ 3 files changed, 58 insertions(+), 14 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-device-lun-type-invalid.xml diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index 03fd541..ee32b73 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -1316,37 +1316,43 @@ </choice> </attribute> </optional> + <interleave> + <ref name="diskSource"/> + <ref name="diskSpecsExtra"/> + </interleave> </group> <group> <attribute name="device"> - <choice> - <value>lun</value> - </choice> + <value>lun</value> </attribute> <optional> <ref name="rawIO"/> </optional> <optional> - <attribute name="sgio"> - <choice> - <value>filtered</value> - <value>unfiltered</value> - </choice> - </attribute> + <ref name="sgIO"/> </optional> + <interleave> + <choice> + <ref name="diskSourceNetwork"/> + <ref name="diskSourceBlock"/> + </choice> + <ref name="diskSpecsExtra"/> + </interleave> </group> </choice> <optional> <ref name="snapshot"/> </optional> - <interleave> - <ref name="diskSource"/> - <ref name="storageSourceExtra"/> - <ref name="diskBackingChain"/> - </interleave> </element> </define> + <define name="diskSpecsExtra"> + <interleave> + <ref name="storageSourceExtra"/> + <ref name="diskBackingChain"/> + </interleave> + </define> + <define name="diskBackingChain"> <choice> <ref name="diskBackingStore"/> @@ -5315,4 +5321,12 @@ <ref name="virYesNo"/> </attribute> </define> + <define name="sgIO"> + <attribute name="sgio"> + <choice> + <value>filtered</value> + <value>unfiltered</value> + </choice> + </attribute> + </define> </grammar> diff --git a/tests/qemuxml2argvdata/qemuxml2argv-disk-device-lun-type-invalid.xml b/tests/qemuxml2argvdata/qemuxml2argv-disk-device-lun-type-invalid.xml new file mode 100644 index 0000000..ed3c89e --- /dev/null +++ b/tests/qemuxml2argvdata/qemuxml2argv-disk-device-lun-type-invalid.xml @@ -0,0 +1,28 @@ +<domain type='qemu'> + <name>QEMUGuest1</name> + <uuid>c7a5fdbd-edaf-9455-926a-d65c16db1809</uuid> + <memory unit='KiB'>219100</memory> + <currentMemory unit='KiB'>219100</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/bin/qemu</emulator> + <disk type='file' device='lun' rawio='yes'> + <driver name='qemu' type='qcow2'/> + <source file='/dev/HostVG/QEMUGuest1'/> + <target dev='vda' bus='virtio'/> + <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> + </disk> + <controller type='usb' index='0'/> + <controller type='ide' index='0'/> + <controller type='pci' index='0' model='pci-root'/> + <memballoon model='virtio'/> + </devices> +</domain> diff --git a/tests/qemuxml2argvtest.c b/tests/qemuxml2argvtest.c index 8d0a4aa..63bf6ff 100644 --- a/tests/qemuxml2argvtest.c +++ b/tests/qemuxml2argvtest.c @@ -817,6 +817,8 @@ mymain(void) QEMU_CAPS_DRIVE, QEMU_CAPS_DRIVE_FORMAT); DO_TEST("disk-drive-no-boot", QEMU_CAPS_DRIVE, QEMU_CAPS_DEVICE, QEMU_CAPS_BOOTINDEX); + DO_TEST_FAILURE("disk-device-lun-type-invalid", + QEMU_CAPS_DRIVE, QEMU_CAPS_DEVICE, QEMU_CAPS_VIRTIO_SCSI); DO_TEST("disk-usb", NONE); DO_TEST("disk-usb-device", QEMU_CAPS_DRIVE, QEMU_CAPS_DEVICE, QEMU_CAPS_DEVICE_USB_STORAGE, -- 1.9.3

[libvirt] [PATCH] qemu: lifecycle: guest get rebooted after reboot and shutdown
by zhang bo 20 Apr '15

20 Apr '15

Steps: 1 virsh reboot guest1 --mode=acpi 2 virsh shutdown guest1 --mode=agent Expected result: As the SHUTDOWN job is after REBOOT, we expected the guest to be *shutoff*. Exacted result: After the 2 steps above, the guest got *rebooted*. The reason to this problem: 1 in qemuDomainReboot(mode acpi), it sets priv->fakeReboot to 1. 2 after shutdown/reboot, qemu monitor IO trigged qemuProcessHandleShutdown(), which finds that priv->fakeReboot is 1, and reboot the guest. Root Cause of the problem: After further look into the problem, We found that the design of acpi/agent shutdown/reboot seems a little chaotic. ----------------------------------- sheet1 who sets fakeReboot ----------------------------------- shutdown reboot acpi Y(0) Y(1) agent N N It's apparently, *acpi-mode* jobs set fakeReboot. ----------------------------------- sheet2 who needs to check fakeReboot(qemuProcessHandleShutdown()) ----------------------------------- shutdown reboot acpi Y Y agent *Y* *N* Things become a little odd here. only agent-mode reboot doesn't check fakeReboot. We can tell from the above 2 sheets, that they're not consistent. *Agent-mode shutdown checks fakeReboot(trigger by SHUTDOWN monitorIO event), while it didn't set it before.* The chaos is not caused by libvirtd, it's a systematic problem, including guest os and qemu. (guest os writes ACPI, triggers qemu, qemu then triggers libvirtd) Solution: A simple solution is to make the 1st sheet consistent to the 2nd sheet, which is: ----------------------------------- sheet3 who should set fakeReboot: ----------------------------------- shutdown reboot acpi Y(0) Y(1) agent *Y(0)* N ----------------------------------- we let agent-mode shutdown set fakeReboot to 0.

[libvirt] Selective block device migration implementation
by Pavel Boldin 18 Apr '15

18 Apr '15

Dear Libvirt Developers, I'm working to implement feature request [1]. The feature request proposes to enhance `libvirt' code so the API caller can specify which block devices are to be migrated using e.g. parameters in the `virDomainMigrateToURI3' call. There is the following issues: 1. It is obvious to identify devices to be migrated using the `device_name'. However, these need to be serialized in either 1) a comma-separated string or in 2) a set of values named like `blockdevice%d' with `blockdevice' value holding amount of block devices to migrate. What is the desired approach here? Can block device name contain commas or should I neglect this possibility? 2. `libvirt' behavior in block devices migration was copied from the `QEMU' implementation that ignores read-only devices as well. So, `libvirt' code will need to pass this list to `QEMU' `migrate' QMP command and this argument should be implemented in the `QEMU'. Is there any implementation advices from your side?

Rework of unpushed patches from series: http://www.redhat.com/archives/libvir-list/2015-April/msg00050.html Details: Patch 1 - Split out the non /dev/* checks into their own to start satisfying Jan's comment in his review of the former patch 3: http://www.redhat.com/archives/libvir-list/2015-April/msg00100.html Patch 2 - New - Flip the logic from assume success, change status to failure, and return to assume failure and only have success when everything completes successfully Patch 3 - Adjustments for previous patch 3 to make use of patch 1's split of the checking for using the /dev path. If we find that the /dev/* is not in use for the pool, then force an error earlier. This makes the check later on not need to compare the returned path to the generated 'devpath' to compensate for the logic in virStorageBackendStablePath which will strdup the incoming target path if something goes wrong in looking up the directory. Since both paths will use the new virStorageBackendPoolUseDevPath slightly differently, if devpath is the same as vol->target.path, then we know it's not because the pool target path was to blame. Patch 4 - Is the former patch 5, but now since patch 3 returns a failure in virStorageBackendSCSINewLun for that bad path, we can use it to be the error arbiter and bug fixer. Former patch 6 - no longer necessary, although it would circumvent any of the above patches being necessary to solve the bug...

[libvirt] [PATCH] libxl: include a XLU_Config in _libxlDriverConfig
by Olaf Hering 17 Apr '15

17 Apr '15

Upcoming changes for vscsi will use libxlutil.so to prepare the configuration for libxl. The helpers needs a xlu struct for logging. Provide one and reuse the existing output as log target.

[libvirt] [PATCH] domcaps: Check for architecture more wisely
by Michal Privoznik 17 Apr '15

17 Apr '15

https://bugzilla.redhat.com/show_bug.cgi?id=1209948 So we have this bug. The virConnectGetDomainCapabilities() API performs a couple of checks before it produces any result. One of the checks is if the architecture requested by user can be run by the binary (again user provided). However, the check is pretty dumb. It merely compares if the default binary architecture matches the one provided by user. However, a qemu binary can run multiple architectures. For instance: qemu-system-ppc64 can run: ppc, ppcle, ppc64, ppc64le and ppcemb. The default is ppc64, so if user requested something else, like ppc64le, the check would have failed without obvious reason.

[libvirt] libvirtd live-locking on CTX_LOCK when doing 'virsh <domid> save /tmp/blah' with guest corrupting memory (on purpose).
by Konrad Rzeszutek Wilk 17 Apr '15

17 Apr '15

Hey Jim, Andrew, and Ian, This is libvirt v1.2.14 + three patches: c82a59b libxl: drop virDomainObj lock when destroying a domain a1c9d30 libxl: acquire a job when destroying a domain 5bd5406 libxl: Move job acquisition in libxlDomainStart to callers For fun I've set up an guest with PCI passthrough and tried to save it (HAHAH) with an disastrous result (xc_save_helper was stuck). Probably due to outstanding DMA operations wreaking havoc. I will shortly send an patch to disallow 'save' with hosted devices but this scenario exposed an interesting livelock that can happen without passthrough if things go wrong. I have not dug entirely in the code so my observation and theory are most likely incorrect. CC-ing Ian and Andrew. The full dump is below, the end result is that libvirtd is locked. Doing 'libvirt list' or any other commands ends with such command hanged. libvirtd itself locks to be deadlocked on CTX_LOCK. On one thread it has received an event (libxl_osevent_occurred_fd) and tries to take the CTX_LOCK, while another thread (number 10) is stuck in eventloop_iteration which holds the CTX_LOCK. It looks like thread #10 is blocking in libxl_read_exactly waiting for 'libxl-save-helper'. Said application (see below) has dispatched an message through helper_getreply and is blocking on __read_nocancel. I presume the message it has dispatched is the same message the 'libxl_osevent_occurred_fd' is trying to get. In other words, one thread has taken the lock, and is blocked waiting for 'libxl-save-helper'. While 'libxl-save-helper' is blocked waiting for its message to be replied to - which another libvirtd thread tries to do but it cannot as the lock has been already taken. Since I did not dig completely in the code I am probably very wrong about this. Would appreciate thoughts whether this is possible and where I've gotten it wrong. Sorry about the control characters and such.

[libvirt] util: log: How about online change logLevel?
by zhang bo 17 Apr '15

17 Apr '15

Sometimes, when we encounter with a problem, we need to set libvirtd log level to DEBUG to dig detailed information. But changing log level requires us to *restart* libvirtd. 1) #vim /etc/libvirt/libvirtd.conf log_level = 1 2) *service libvirtd restart* We think that it makes sense to develop an API to *online* change log level, without restarting libvirtd. What's your opinion? If it's necessary, I'd like to post a patch here.

[libvirt] request for backwards compatibility
by Kash Pande 17 Apr '15

17 Apr '15

Hi there, I've been trying to use libvirt-php to bring libvirt support to jentu which runs on mostly Debian Wheezy machines. I've had a few bugs setting network devices as active with the released (0.4.8) version: PHP Warning: libvirt_network_get_information(): Invalid XPath node for network gateway IP address in /var/www/libjentu-virt.php on line 54 PHP Warning: libvirt_network_set_active() expects exactly 2 parameters, 1 given in /var/www/libjentu-virt.php on line 55 PHP Warning: libvirt_network_set_active(): Invalid arguments in /var/www/libjentu-virt.php on line 55 Building the latest Git repository results in: gcc -g -O2 -Wall -fpic -DCOMPILE_DL_LIBVIRT=1 -I/usr/include/php5 -I/usr/include/php5/main -I/usr/include/php5/TSRM -I/usr/include/php5/Zend -I/usr/include/php5/ext -I/usr/include/php5/ext/date/lib -c -o libvirt-php.o libvirt-php.c -I/usr/include/libxml2 -DHAVE_CONFIG_H libvirt-php.c: In function ‘zm_startup_libvirt’: libvirt-php.c:1179:2: error: ‘VIR_DOMAIN_VCPU_GUEST’ undeclared (first use in this function) libvirt-php.c:1179:2: note: each undeclared identifier is reported only once for each function it appears in libvirt-php.c: In function ‘get_next_free_numeric_value’: libvirt-php.c:2719:6: warning: format ‘%x’ expects argument of type ‘unsigned int *’, but argument 3 has type ‘long int *’ [-Wformat] make[2]: *** [build] Error 1 And this is because debian wheezy has an old version of libvirt that does not have this declared. The proper solution looks like it'd be a configure-time check and enable or disable the new VCPU guest modifiers if they are not available because I'm not so sure wheezy will ever get a newer version of libvirt. Thanks, Kash Pande Jentu Technologies, Inc. http://jentu-networks.com
