[libvirt] [PATCH 0/3] start of patches to support VFIO device assignment
by Laine Stump 26 Apr '13

26 Apr '13

This work isn't finished, but since there's a freeze coming up in a few days, I thought I should send these patches that *are* finished to get them out of the way before the last minute rush. Patch 1 is trivial. Patch 2 is longer, but completely mechanical (NOTE: there may be some uses of that struct living in code that I lack the environment to compile for, so test builds by people with odd platforms would be appreciated!) Patch 3 is standard parser/formatter/RNG/docs for the new XML. I haven't added any test cases, because lacking backend functionality I could only test xml-to-xml, which would require adding yet another test xml file, and I'd rather wait until the backend commandline-building code is in place, then simply add the new element to a few existing test XML files. In email awhile ago, danpb had suggested <driver name='vfio|qemu'/> I've used <driver name='kvm'/> because, unlike vhost-net where <driver name='qemu'/> indicates that the driver used is in the usermode qemu process (and *not* in the kernel), in this case <driver name='kvm'/> indicates that the driver used is in the kernel (and I've seen it referenced in several places as being "done by KVM", but never as "done by QEMU" (makes sense, since qemu is all in userland) Laine Stump (3): qemu: detect vfio-pci device assignment support conf: put hostdev pci address in a struct conf: formatter/parser/RNG/docs for hostdev <driver name='kvm|vfio'/> docs/formatdomain.html.in | 42 ++++++++++++++++++++- docs/formatnetwork.html.in | 15 ++++++++ docs/schemas/domaincommon.rng | 79 ++++++++++++++++++++++++++-------------- docs/schemas/network.rng | 11 ++++++ src/conf/domain_audit.c | 8 ++-- src/conf/domain_conf.c | 48 +++++++++++++++++++++--- src/conf/domain_conf.h | 15 +++++++- src/network/bridge_driver.c | 24 ++++++------ src/qemu/qemu_capabilities.c | 3 ++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 34 ++++++++--------- src/qemu/qemu_hostdev.c | 42 ++++++++++----------- src/qemu/qemu_hotplug.c | 14 +++---- src/security/security_apparmor.c | 8 ++-- src/security/security_dac.c | 16 ++++---- src/security/security_selinux.c | 16 ++++---- src/security/virt-aa-helper.c | 10 ++--- src/xen/xend_internal.c | 10 ++--- src/xenxs/xen_sxpr.c | 16 ++++---- src/xenxs/xen_xm.c | 16 ++++---- 20 files changed, 286 insertions(+), 142 deletions(-) -- 1.7.11.7

[libvirt] [PATCH] build: avoid unsafe functions in libgen.h
by Eric Blake 25 Apr '13

25 Apr '13

POSIX says that both basename() and dirname() may return static storage (aka they are not thread-safe); and that they may but not must modify their input argument. Furthermore, <libgen.h> is not available on all platforms. For these reasons, you should never use these functions in a multi-threaded library. Gnulib instead recommends a way to avoid the portability nightmare: gnulib's "dirname.h" provides useful counterparts. The obvious dir_name() and base_name() are GPL (because they malloc(), but call exit() on failure) so we can't use them; but the LGPL variants mdir_name() (malloc's or returns NULL) and last_component (always points into the incoming string without modifying it, differing from basename semantics only on corner cases like the empty string that we shouldn't be hitting in the first place) are already in use in libvirt. This finishes the swap over to the safe functions. * cfg.mk (sc_prohibit_libgen): New rule. * src/util/vircgroup.c: Fix offenders. * src/parallels/parallels_storage.c (parallelsPoolAddByDomain): Likewise. * src/parallels/parallels_network.c (parallelsGetBridgedNetInfo): Likewise. * src/node_device/node_device_udev.c (udevProcessSCSIHost) (udevProcessSCSIDevice): Likewise. * src/storage/storage_backend_disk.c (virStorageBackendDiskDeleteVol): Likewise. * src/util/virpci.c (virPCIGetDeviceAddressFromSysfsLink): Likewise. * src/util/virstoragefile.h (_virStorageFileMetadata): Avoid false positive.

Hello, In "Memory Ballon" ( http://www.libvirt.org/formatdomain.html#elementsMemBalloon ) section, the second XML exemple has an error. Effectively, the documentation shows the following : ... <devices> <watchdog model='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </devices> </domain> but it should be ... <devices> <memballoon model='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </memballoon> </devices> </domain> Best regards,

[libvirt] [PATCH] Fix usb master startport parsing
by Martin Kletzander 25 Apr '13

25 Apr '13

When all usb controllers connected to the same bus have <master startport='x'/> specified, none of them have 'id=usb' assigned and thus qemu fails due to invalid masterport specification (we use 'usb' for that purpose). Adding a check that at least one of the controllers is specified without <master startport='x'/> and in case this happens, don't error out, just emit a warning and fix it within the first such controller found. This makes UX better by not forcing them to fix controller definition after removing the only non-master usb controller.

by Michal Privoznik 25 Apr '13

[libvirt] Virtual machine using the encrypted image fail to migrate by libvirt
by yongcheng.wu＠i-soft.com.cn 25 Apr '13

25 Apr '13

The qemu-kvm and libvirt migration process is as follows: e.g: migrate from VM1 to VM2 (1)virtual machine migration process by qemu-kvm (qemu-kvm-0.12.1.2-2.209.el6)is as follows: ==>VM1 1.set password 2.continue ==>VM2 3.start and wait for migration(--incoming) ==>VM1 4.migrating 5.migrate finish 6.close VM1 ==>VM2 7.clear password 8.set password 9.continue (2)virtual machine migration process by libvirt is as follows: ==>VM1 1.set password 2.continue ==>VM2 3.start (--incoming) 4.set password 5.wait for migration ==>VM1 6.migrating 7.migrate finish 8.close VM1 ==>VM2 9.clear password (here we lost the password !!) 10.continue The migration process by libvirt will cause the migrate fail, because qemu-kvm will clear password before it continues. So, I move step 4 just before step 10.

[libvirt] [PATCH v5 1/2] Add NVRAM device
by Li Zhang 25 Apr '13

25 Apr '13

From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> For pSeries guest in QEMU, NVRAM is one kind of spapr-vio device. Users are allowed to specify spapr-vio devices'address. But NVRAM is not supported in libvirt. So this patch is to add NVRAM device to allow users to specify its address. In QEMU, NVRAM device's address is specified by "-global spapr-nvram.reg=xxxxx". In libvirt, XML file is defined as the following: <nvram> <address type='spapr-vio' reg='0x3000'/> </nvram> Signed-off-by: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> --- v5 -> v4: * Add NVRAM capability suggested by Osier Yang. * Define macros for VIO device address. * Define qemuBuildNVRAMDevStr as static func. * Correct several error messages. * Add xml2xml test case v4 -> v3: * Seperate NVRAM definition from qemu command line parser. v3 -> v2: * Add NVRAM in domaincommon.rng and formatdomain.xml.in suggested by Daniel P.Berrange * Add NVRAM test cases suggested by Daniel P.Berrange * Remove nvram allocation when it is not specified suggested by Daniel P.Berrange * Add several error reports suggested by Daniel P.Berrange v2 -> v1: * Add NVRAM parameters parsing in qemuParseCommandLine docs/formatdomain.html.in | 35 +++++++++++++++++++ docs/schemas/domaincommon.rng | 10 ++++++ src/conf/domain_conf.c | 81 +++++++++++++++++++++++++++++++++++++++++++ src/conf/domain_conf.h | 10 ++++++ 4 files changed, 136 insertions(+) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 0cc56d9..4a7a66f 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -4502,6 +4502,41 @@ qemu-kvm -net nic,model=? /dev/null </dd> </dl> + <h4><a name="elementsNVRAM">NVRAM device</a></h4> + <p> + One NVRAM device is always added to pSeries guests on PPC64. + And on PPC64, NVRAM devices' address type are VIO which + allows users to change.<code>nvram</code> element in XML file + is provided to specify its address. + Currently, libvirt only considers configuration for pSeries guests. + </p> + <p> + Example: usage of NVRAM configuration + </p> +<pre> + ... + <devices> + <nvram> + <address type='spapr-vio' reg='0x3000'/> + </nvram> + </devices> + ... +</pre> + <dl> + <dt><code>spapr-vio</code></dt> + <dd> + <p> + VIO device address type, this is only for PPC64. + </p> + </dd> + <dt><code>reg</code></dt> + <dd> + <p> + Devices' address + </p> + </dd> + </dl> + <h3><a name="seclabel">Security label</a></h3> <p> diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index 3976b82..86ef540 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -2793,6 +2793,13 @@ </optional> </element> </define> + <define name="nvram"> + <element name="nvram"> + <optional> + <ref name="address"/> + </optional> + </element> + </define> <define name="memballoon"> <element name="memballoon"> <attribute name="model"> @@ -3280,6 +3287,9 @@ <optional> <ref name="memballoon"/> </optional> + <optional> + <ref name="nvram"/> + </optional> </interleave> </element> </define> diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 1643f30..acaec20 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -194,6 +194,7 @@ VIR_ENUM_IMPL(virDomainDevice, VIR_DOMAIN_DEVICE_LAST, "smartcard", "chr", "memballoon", + "nvram", "rng") VIR_ENUM_IMPL(virDomainDeviceAddress, VIR_DOMAIN_DEVICE_ADDRESS_TYPE_LAST, @@ -1560,6 +1561,16 @@ void virDomainMemballoonDefFree(virDomainMemballoonDefPtr def) VIR_FREE(def);

[libvirt] virNodeDevice APIs and VFIO
by Laine Stump 24 Apr '13

24 Apr '13

Yesterday for the first time I consciously noticed the virNodeDeviceDettach and virNodeDeviceReAttach APIs, and found that they are hardcoded to bind to/unbind from the pci-stub driver for qemu, and the "pciback" driver for Xen. If we want these APIs to be useful for VFIO, they will need to bind to the vfio driver instead, but there is currently no method in those APIs to specify which driver to bind to. I guess we could do this with new virNodeDeviceDetachFlags() and virNodeDeviceReAttachFlags() APIs which have a flag to indicate vfio, but before going to that trouble I'd like to know if these APIs are actually used or if they are deprecated (they don't seem to be of any use if the hostdev devices you're assigning have "managed='yes'" - as far as I can see, setting managed='yes' just makes the bind/unbind from the stub driver an automatic part of assigning/un-assigning the device to a guest). (Beyond that, this would be exposing a lower level of detail in the APIs than the original functions, and I'm not sure if it's appropriate - the choice of stub driver was previously hidden in each hypervisor driver).

[libvirt] [PATCH 0/6] Cleanup of internal API naming conventions
by Daniel P. Berrange 24 Apr '13

24 Apr '13

The naming conventions used for APIs in both src/driver.h and src/remote/remote_protocol.x should follow the public API naming, but there are a great many violations of this. This series fixes them all, and adds some tests which will help prevent regressions.

[libvirt] [PATCH] qemu: Generate agent socket path if missing

[libvirt] Using leases with virtlockd
by Jim Fehlig 24 Apr '13

24 Apr '13

Nearly a question for the users list, but I might be encountering a bug too. I'm using virtlockd with 'auto_disk_leases = 0' and struggle with the correct configuration for a lease in the domXML. Using <lease> <lockspace>test-ls</lockspace> <key>test-lock</key> <target path='/var/lib/libvirt/lockd'/> </lease> results in the following error when starting the domain internal error Lockspace for path /var/lib/libvirt/lockd/test-ls It appears the path attribute + lockspace are used as the Lockspace for this lease. But I'm not sure what "Lockspace" means in this context. Is it a directory? A file? I assume the latter since it is just flock()ed when the domain is started, right? I'll be happy to provide patches to fix any bugs that might exist here (docs included), but need understand the correct configuration of leases with virtlockd first :). BTW, nice piece of work Daniel! Regards, Jim

[libvirt] [PATCH] Use camelCase for XML attribute numQueues

In commit d4bf0a9, we used num_queues for an attribute in the XML, but the consensus is that we use camelCase for that.

That is correct, setting the native vlan changes how an untagged packet is handled when it enters the port. The difference between the 'tagged' and 'untagged' modes is in how packets on the native vlan are processed before exiting the port. > And what happens when native_mode='yes' but there is no native_tag? In that case you configuration is invalid, and will get an error. > (that's what I was trying to describe with <tag id='123' > native='untagged'/>, but I don't even know if that makes sense, because > I don't know exactly what is the native vlan tag and what is done with > it :-) That arrangement would make sense, I chose the arrangement I did for two main reasons. There can only be one native vlan on a port, making it an attribute of the 'vlan' tag enforces this. Also, I wanted to keep the validation and processing separate rather than add 'if native' branches to the loops that operate on the vlan id list. I can see the advantage of having a single setting to configure the native vlan, rather than the two attributes I proposed. If the new suggestion is preferred I can rework my patch to use that format. > Also, is it valid to have a native_mode/native_tag if trunk='no'? (right > now trunk is automatically set to 'yes' if there is more than one vlan tag) It isn't valid to have trunk='no' and the native settings. Therefore "<vlan trunk='no' native_mode='tagged' native_tag='123'>" will get an error if you try to enter it. If no "trunk" attribute is set explicitly then it will be set to 'yes'. This means "<vlan native_mode='tagged' native_tag='123'>" is equivalent to "<vlan trunk='yes' native_mode='tagged' native_tag='123'>". > > > </network> > > diff --git a/tests/networkxml2xmlout/openvswitch-net.xml > > b/tests/networkxml2xmlout/openvswitch-net.xml > > index a3d82b1..ab3d797 100644 > > --- a/tests/networkxml2xmlout/openvswitch-net.xml > > +++ b/tests/networkxml2xmlout/openvswitch-net.xml > > @@ -21,4 +21,13 @@ > > <parameters profileid='alice-profile'/> > > </virtualport> > > </portgroup> > > + <portgroup name='tagged'> > > + <vlan trunk='yes' native_mode='tagged' native_tag='123'> > > + <tag id='555'/> > > + <tag id='444'/> > > + </vlan> > > + <virtualport> > > + <parameters profileid='tagged-profile'/> > > + </virtualport> > > + </portgroup> > > </network> > > > Protected by Websense Hosted Email Security -- www.websense.com

[libvirt] [PATCH] qemu: Fix setting of memory tunables
by Peter Krempa 22 Apr '13

22 Apr '13

Refactoring done in 19c6ad9ac7e7eb2fd3c8262bff5f087b508ad07f didn't correctly take into account the order cgroup limit modification needs to be done in. This resulted into errors when decreasing the limits. The operations need to take place in this order: decrease hard limit change swap hard limit or change swap hard limit increase hard limit This patch also fixes the check if the hard_limit is less than swap_hard_limit to print better error messages. For this purpose I introduced a helper function virCompareLimitUlong to compare limit values where value of 0 is equal to unlimited. Additionally the check is now applied also when the user does not provide all of the tunables through the API and in that case the currently set values are used.

[libvirt] [PATCH] rng: tighten up domain <controller> schema
by Laine Stump 22 Apr '13

22 Apr '13

The rng schema for <controller> had been non-specific about which types of controllers allowed which models, and also allowed the num_queues attribute (since that hasn't been released yet, should we rename it to "numQueues"?) and <master> subelement to be included for any controller type.

[libvirt] [PATCH 0/5] qemu: invoke qemu-bridge-helper from libvirtd
by Paolo Bonzini 19 Apr '13

19 Apr '13

The <interface type='bridge'> is working mostly because of a bad design decision in Linux. Ideally, QEMU would run with an empty capability bounding set and would not be able to do any privileged operation (not even by running a helper program). This is not the case because dropping capabilities from the bounding set requires a capability of its own, CAP_SETPCAP; thus QEMU does *not* run with an empty bounding set if invoked via qemu:///session. This series lets libvirtd invoke the privileged helper program on its own, which is a cleaner design that would work even if the above Linux bug was not there. Also, this adds a <target dev='tap0'/> element to the XML of an active domain using <interface type='bridge'>. libvirt now needs to know the path to the helper (patch 3), and must not set permitted/effective capabilities on children when running unprivileged (patches 1/2). Apart from this, the recvfd and virCommand APIs make the task almost trivial. Paolo Bonzini (5): util: simplify virSetUIDGIDWithCaps util: allow using virCommandAllowCap with setuid helpers qemu_conf: add new configuration key bridge_helper virnetdevtap: add virNetDevTapGetName qemu: launch bridge helper from libvirtd src/libvirt_private.syms | 1 + src/qemu/libvirtd_qemu.aug | 1 + src/qemu/qemu.conf | 8 +++ src/qemu/qemu_command.c | 133 +++++++++++++++++++++++++++---------- src/qemu/qemu_command.h | 1 - src/qemu/qemu_conf.c | 3 + src/qemu/qemu_conf.h | 1 + src/qemu/qemu_hotplug.c | 25 +++---- src/qemu/test_libvirtd_qemu.aug.in | 1 + src/util/virnetdevtap.c | 33 +++++++++ src/util/virnetdevtap.h | 3 + src/util/virutil.c | 36 +++++++--- 12 files changed, 183 insertions(+), 63 deletions(-) -- 1.8.1.4

[libvirt] [PATCH] audit: properly encode device path in cgroup audit
by Eric Blake 19 Apr '13

19 Apr '13

https://bugzilla.redhat.com/show_bug.cgi?id=922186 Commit d04916fa introduced a regression in audit quality - even though the code was computing the proper escaped name for a path, it wasn't feeding that escaped name on to the audit message. As a result, /var/log/audit/audit.log would mention a field path=/dev/hpet instead of the intended path="/dev/hpet", which in turn caused ausearch to format the audit log as path=(null). * src/conf/domain_audit.c (virDomainAuditCgroupPath): Use constructed encoding.

[libvirt] [PATCH] qemu: Enable the capability bit for -no-kvm-pit-reinjection on x86 only
by Viktor Mihajlovski 19 Apr '13

19 Apr '13

From: Boris Fiuczynski <fiuczy(a)linux.vnet.ibm.com> On architectures not supporting the Intel specific programmable interval timer, like e.g. S390, starting a domain with a clock definition containing a pit timer results in the error "Option no-kvm-pit-reinjection not supported for this target". By moving the capability enablement for -no-kvm-pit-reinjection from the InitQMPBasic section into the x86_64 and i686 only enablement section all other architectures are no longer automatically enabled. In addition architecture related capabilities enablements were refactored into a new architecture bound capabilities initialization function.

This patch adds support for loading status files of transient networks (that already were generated) so that the status isn't lost. This patch chops up virNetworkObjUpdateParseFile and turns it into virNetworkLoadState and a few friends that will help us to load status XMLs and refactors the functions that are loading the configs to use them. --- Notes: Version 2: - renamed confDir to statusDir - clarified comment about goto - removed check if bridge name is present in XML - switched removal of inactive transient networks to while loop to avoid re-iteration src/conf/network_conf.c | 207 ++++++++++++++++++++++++++++---------------- src/conf/network_conf.h | 10 ++- src/libvirt_private.syms | 2 +- src/network/bridge_driver.c | 51 ++++++----- 4 files changed, 171 insertions(+), 99 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 75584a0..18a7d57 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -1967,81 +1967,6 @@ cleanup: return def; } -int -virNetworkObjUpdateParseFile(const char *filename, - virNetworkObjPtr net) -{ - int ret = -1; - xmlDocPtr xml = NULL; - xmlNodePtr node = NULL; - virNetworkDefPtr tmp = NULL; - xmlXPathContextPtr ctxt = NULL; - - xml = virXMLParse(filename, NULL, _("(network status)")); - if (!xml) - return -1; - - ctxt = xmlXPathNewContext(xml); - if (ctxt == NULL) { - virReportOOMError(); - goto cleanup; - } - - node = xmlDocGetRootElement(xml); - if (xmlStrEqual(node->name, BAD_CAST "networkstatus")) { - /* Newer network status file.

[libvirt] [PATCH v4 1/2 RESEND] Add NVRAM device
by Li Zhang 19 Apr '13

19 Apr '13

From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> For pSeries guest in QEMU, NVRAM is one kind of spapr-vio device. Users are allowed to specify spapr-vio devices'address. But NVRAM is not supported in libvirt. So this patch is to add NVRAM device to allow users to specify its address. In QEMU, NVRAM device's address is specified by "-global spapr-nvram.reg=xxxxx". In libvirt, XML file is defined as the following: <nvram> <address type='spapr-vio' reg='0x3000'/> </nvram> Signed-off-by: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> --- v4 -> v3: * Sperate NVRAM definition from qemu command line parser. v3 -> v2: * Add NVRAM in domaincommon.rng and formatdomain.xml.in suggested by Daniel P.Berrange * Add NVRAM test cases suggested by Daniel P.Berrange * Remove nvram allocation when it is not specified suggested by Daniel P.Berrange * Add several error reports suggested by Daniel P.Berrange v2 -> v1: * Add NVRAM parameters parsing in qemuParseCommandLine docs/formatdomain.html.in | 35 ++++++++++++++++++++ docs/schemas/domaincommon.rng | 10 ++++++ src/conf/domain_conf.c | 76 +++++++++++++++++++++++++++++++++++++++++++ src/conf/domain_conf.h | 10 ++++++ 4 files changed, 131 insertions(+) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index d400e35..f590304 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -4415,6 +4415,41 @@ qemu-kvm -net nic,model=? /dev/null </dl> + <h4><a name="elementsNVRAM">NVRAM device</a></h4> + <p> + One NVRAM device is always added to pSeries guests on PPC64. + And on PPC64, NVRAM devices' address type are VIO which + allows users to change.<code>nvram</code> element in XML file + is provided to specify its address. + Currently, libvirt only considers configuration for pSeries guests. + </p> + <p> + Example: usage of NVRAM configuration + </p> +<pre> + ... + <devices> + <nvram> + <address type='spapr-vio' reg='0x3000'/> + </nvram> + </devices> + ... +</pre> + <dl> + <dt><code>spapr-vio</code></dt> + <dd> + <p> + VIO device address type, this is only for PPC64. + </p> + </dd> + <dt><code>reg</code></dt> + <dd> + <p> + Devices' address + </p> + </dd> + </dl> + <h3><a name="seclabel">Security label</a></h3> <p> diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index 2c31f76..2b58d95 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -2764,6 +2764,13 @@ </optional> </element> </define> + <define name="nvram"> + <element name="nvram"> + <optional> + <ref name="address"/> + </optional> + </element> + </define> <define name="memballoon"> <element name="memballoon"> <attribute name="model"> @@ -3208,6 +3215,9 @@ <optional> <ref name="memballoon"/> </optional> + <optional> + <ref name="nvram"/> + </optional> </interleave> </element> </define> diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 36a46da..3a5e59a 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -193,6 +193,7 @@ VIR_ENUM_IMPL(virDomainDevice, VIR_DOMAIN_DEVICE_LAST, "smartcard", "chr", "memballoon", + "nvram", "rng") VIR_ENUM_IMPL(virDomainDeviceAddress, VIR_DOMAIN_DEVICE_ADDRESS_TYPE_LAST, @@ -1552,6 +1553,16 @@ void virDomainMemballoonDefFree(virDomainMemballoonDefPtr def) VIR_FREE(def);

[libvirt] QEMU/KVM support for non zero PCI domain
by Charles Peri 18 Apr '13

18 Apr '13

Hi, I am trying to run Virt-Manager, using KVM on a SGIUV100 system with RHEL 6.1. I am trying to enable PCI pass-thorugh for the Mellanox, but the PCI domain for the device is 0001. 0001:01:00.0 Ethernet controller: Mellanox Technologies MT26448 [ConnectX EN 10GigE, PCIe 2.0 5GT/s] (rev b0) 0001:02:00.0 InfiniBand: Mellanox Technologies MT26428 [ConnectX VPI PCIe 2.0 5GT/s - IB QDR / 10GigE] (rev b0) When I try to add the device, I get an error stating that "Can't assign device inside non- zero PCI segment, as this KVM module doesn't support it". Is there a version of KVM module that supports non zero PCI segment? Sorry, if this is not the right email list to ask this question, I checked on the KVM IRC, but haven't got any answer. Thanks, Charles

[libvirt] [PATCHv3] Support for static routes on a virtual bridge
by Gene Czarcinski 18 Apr '13

18 Apr '13

This patch adds support for adding a static route for a network. The "gateway" sub-element specifies the gateway's IP address. Both IPv4 and IPv6 static routes are supported although it is expected that this functionality will have more use with IPv6. This updates add the <route> element to define a static route. The gateway= subelement species the gateway address which is to receive the packets forwarded to the network specified on the <route> definition. Tests are done to validate that the input definitions are correct. For example, for a static route ip definition, the address must be a network address and not a host address. Additional checks are added to ensure that the specified gateway has a network defined on this bridge. Whan a static route is added to a bridge, there is a slight possibility that the gateway address will be incorrect. If this is handled as an error, that bridge becomes unusable and can only be recovered by rebooting. If the error is ignored, then that network can be destroyed and the network definition file edited to correct the problem. Unfortunately, the error message only appears in syslog. However, with the checks performed when the network definition file is parsed, it is unlikely that this condition will ever occur. The command used is of the following form: ip route add <address>/<prefix> via <gateway> dev <virbr-bridge> \ proto static metric 1 .

[libvirt] need help: what should be supported?
by Gene Czarcinski 18 Apr '13

18 Apr '13

I need some help/guidance as to what networking characteristics should be supported by libvirt. Mostly, I am asking what should be valid for a prefix. For IPv4: The prefix can theoretically range from 0 to 32. Typically, the values of 8, 16 or 24 is used. For an IP specification, should I be able to specify prefix=32 (netmask 255.255.255.255)? This is not a network specification but one for a specific guest-host ... but, what will the virtualization host have for the address on this interface? Proposed: prefix (or equivalent netmask) must be 8 < prefix < 29 For IPv6: Similar to IPv4 but the range is (theoretically) 0 to 128. However, DHCPv6 and RA will **ONLY** work for prefix=64 ... nothing greater and nothing less. For an network on an interface which is visible to the virtualization host, it must have an address for the host; therefore, prefix <127. I am not sure what an IP definition with prefix=0 means for a libvirt virtual network. Proposed: Prefix=64 for DHCPv6 and/or RA support. For other network addresses (such as static route), 7 < prefix <= 64. Most IPv6 software does not appear to handle subnets where prefix > 64 except for prefix=128 for a specific host address. That is not to say that prefix <64 prefix < 128 could not have a meaning and be useful. But, if supported, how should it be specified so that user problems are minimized ... or do we just support it and what happens is a user problem? Comments? Suggestions?? Gene

[libvirt] [libvirt-designer 0/9] Handle more devices in GVirDesignerDomain
by Christophe Fergeau 18 Apr '13

18 Apr '13

This series builds on the previous one (the one adding gvir_designer_domain_get_supported_devices()). It adds methods to add more devices disks/network interfaces to GVirDesignDomain. Some parts like 'Automatically add SPICE channel with SPICE graphics' may not be what we want, but I've tried to make the external API as easy as possible. Christophe

[libvirt] Improve disk bus type generation
by Christophe Fergeau 18 Apr '13

18 Apr '13

This is mostly an excuse to add a _get_supported_devices() method used in fallback cases (when the deployment does not specify a disk driver to be used) as this will be useful later. The list of supported devices is generated with - devices supported both by the OS and the platform (hypervisor) - devices for which we have a OS driver, and which are supported by the platform When doing this work, I realized a few things were missing from libosinfo: - to properly guess the bus to use for a disk (sata, ide, scsi, ...) from a libosinfo device, we'd need to have the PCI subclass in libosinfo. This will probably need to be added at some point - something that would be nice for easier fallback when the deployment does not specify a device would be a way for OS/platforms to indicate that their preferred disk device is virtio-disk, then sata device XXX, ... I also think deployments would be more flexible if a deployment meant for qemu-1.2.0 could be used with qemu-1.3.0. Currently, osinfo_db_find_deployment does not follow 'upgrades' relations on platforms, but I think it would be more convenient if it did. Christophe

[libvirt] [libvirt-designer PATCHv2] Add support for floppies and CDROMs
by Christophe Fergeau 18 Apr '13

18 Apr '13

This mirrors disk_file/disk_device API so that it's possible to add CDROMs and floppies to a GVirDesignerDomain. This also adds the corresponding -C/-F options to virtxml --- Here is a reworked version of my patch to add support for CDROMs which does not override the 'format' parameter this time.

Re: [libvirt] [PATCH 2/3][ocaml] Add event callback implementation based on virConnectDomainEventRegisterAny
by David Scott 18 Apr '13

18 Apr '13

Hi, I just spotted a flaw in my OCaml event callback patch. I was hoping to ensure the ocaml bindings build against libvirt 0.9.1 and later. For functions, I remembered to include the usual symbol detection magic. However I forgot that there are also some enums which were added later than 0.9.1 i.e. all of these: On Wed, Apr 17, 2013 at 11:16 AM, David Scott <scott.dj(a)gmail.com> wrote: [snip] > + case VIR_DOMAIN_EVENT_ID_IO_ERROR_REASON: > + cb = VIR_DOMAIN_EVENT_CALLBACK(s_s_i_s_callback); > + break; > + case VIR_DOMAIN_EVENT_ID_CONTROL_ERROR: > + cb = VIR_DOMAIN_EVENT_CALLBACK(u_callback); > + break; > + case VIR_DOMAIN_EVENT_ID_BLOCK_JOB: > + cb = VIR_DOMAIN_EVENT_CALLBACK(s_i_i_callback); > + break; > + case VIR_DOMAIN_EVENT_ID_DISK_CHANGE: > + cb = VIR_DOMAIN_EVENT_CALLBACK(s_s_s_i_callback); > + break; > + case VIR_DOMAIN_EVENT_ID_TRAY_CHANGE: > + cb = VIR_DOMAIN_EVENT_CALLBACK(s_i_callback); > + break; > + case VIR_DOMAIN_EVENT_ID_PMWAKEUP: > + cb = VIR_DOMAIN_EVENT_CALLBACK(i_callback); > + break; > + case VIR_DOMAIN_EVENT_ID_PMSUSPEND: > + cb = VIR_DOMAIN_EVENT_CALLBACK(i_callback); > + break; > + case VIR_DOMAIN_EVENT_ID_BALLOON_CHANGE: > + cb = VIR_DOMAIN_EVENT_CALLBACK(i64_callback); > + break; > + case VIR_DOMAIN_EVENT_ID_PMSUSPEND_DISK: > + cb = VIR_DOMAIN_EVENT_CALLBACK(i_callback); > + break; > These currently cause the build to break against older libvirts. I'll rework this and resubmit once I've verified it definitely does work against an older version. Sorry for the noise! Cheers, Dave

[libvirt] [PATCH] Change default resource partition to /machine
by Daniel P. Berrange 18 Apr '13

18 Apr '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> After discussions with systemd developers it was decided that a better default policy for resource partitions is to have 3 default partitions at the top level /system - system services /machine - virtual machines / containers /user - user login session This ensures that the default policy isolates guest from user login sessions & system services, so a mis-behaving guest can't consume 100% of CPU usage if other things are contending for it. Thus we change the default partition from /system to /machine Signed-off-by: Daniel P.

[libvirt] [PATCH 0/3] Speeding up the wait for session daemon
by Martin Kletzander 18 Apr '13

18 Apr '13

When the session daemon is spawned and ends with an error before the spawning process notices, it becomes waiting for Godot (fortunately with a timeout of about 20 seconds). With this series, there is pidfile created for the spawned daemon and the pid is being checked for to make sure we are not wasting precious time. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=927369 Martin Kletzander (3): Add missing error reporting Move daemonPidFilePath into virutil.c Speed up waiting for the session daemon daemon/libvirtd.c | 43 +++---------------------------------------- src/libvirt_private.syms | 1 + src/rpc/virnetsocket.c | 41 +++++++++++++++++++++++++++++++++++------ src/util/virutil.c | 45 ++++++++++++++++++++++++++++++++++++++++++++- src/util/virutil.h | 4 ++++ 5 files changed, 87 insertions(+), 47 deletions(-) -- 1.8.1.5

[libvirt] libvirt-1.0.3 vs qemu-1.4
by Yin Olivia-R63875 18 Apr '13

18 Apr '13

Hi guys, I used to go through libvirt (1.0.3) use cases with qemu-1.0 + linux-3.0.43. Recently I tried Linux-3.8.4 + qemu-1.4. But it can't start qemu domain. --------------------------------- root@p1022ds:~# virsh version Compiled against library: libvirt 1.0.3 Using library: libvirt 1.0.3 Using API: QEMU 1.0.3 Running hypervisor: QEMU 1.4.0 root@p1022ds:~# cat test.args /usr/bin/qemu-system-ppc -name test -M mpc8544ds -enable-kvm -m 256 -nographic -kernel /media/ram/uImage -initrd /media/ram/ramdisk -append "root=/dev/ram rw console=ttyS0,115200" -serial pty root@p1022ds:~# virsh domxml-from-native qemu-argv test.args >test.xml root@p1022ds:~# virsh define test.xml Domain test defined from test.xml root@p1022ds:~# virsh start test error: Failed to start domain test error: internal error no assigned pty for device charserial0 --------------------------------- I don't know if it depends on qemu version or kernel config. Do you have any idea about this issue? Best Regards, Olivia

[libvirt] [PATCH] Switch to a more extensible annotation system for RPC protocols
by Daniel P. Berrange 18 Apr '13

[libvirt] doc: write separate module for hostdev passthrough and in-use tracking
by Chunyan Liu 18 Apr '13

Hi, List, As the mail I've sent a week before: https://www.redhat.com/archives/libvir-list/2013-March/msg00730.html I'm willing to push this work forward so that the passthrough APIs could be reused by qemu driver and libxl driver (which doesn't support pci passthrough yet and tries to add this function recently), or other drivers. But since this work affacts a lot, I'm not sure if I can control it in a correct way. I write a draft to describe what I'm considering how to do, as in the following and in attachment. Hope to get your review, comment and guidence to improve the work before start coding. Any feedback will be very appreciated! Thanks! Chunyan ------------------------ DRAFT: Write separate module for hostdev passthrough 1. Purposes: * Move hostdev passthrough APIs from qemu_hostdev.ch to separate module so that they could be reused by other hypervisors too * Maintain global in-use state of hostdevs 2. Module design (draft): * New module name: hostdev_driver * New module files: hostdev_driver.ch hostdev_conf.ch * New Definitions: ## [src/driver.h] typedef struct _virHostdevDriver virHostdevDriver; typedef virHostdevDriver *virHostdevDriverPtr; struct _virHosedevDriver { const char *name; virDrvOpen open; virDrvClose close; virDrvPrepareHostdevs prepareHostdevs; virDrvPreparePciHostdevs preparePciHostdevs; virDrvprepareUsbHostdevs prepareUsbHostdevs; virDrvReattachHostdevs reattachHostdevs; virDrvReattachPciHostdevs reattachPciHostdevs; virDrvReattachUsbHostdevs reattachUsbHostdevs; virDrvGetActivePciHostdevList getActivePciHostdevList; virDrvGetActiveUsbHostdevList getActiveUsbHostdevList; virDrvGetDomainActivePciHostdevList getDomainActivePciHostdevList; virDrvGetDomainActiveUsbHostdevList getDomainActiveUsbHostdevList; }; ## [src/hostdev/hostdev_conf.h] typedef struct _virHostdevDriverState virHostdevDriverState; typedef virHostdevDriverState *virHostdevDriverStatePtr; struct _virHostdevDriverState { virMutex lock; virPCIDeviceListPtr activePciHostdevs; virPCIDeviceListPtr inactivePciHostdevs; virUSBDeviceListPtr activeUsbHostdevs;

static virStateDriver hostdevStateDriver = { .name = "hostdev", .initialize = hostdevDriverStartup, .cleanup = hostdevDriverCleanup, .reload = hostdevDriverReload, }; * Changed Definitions: struct _virPCIDevice { ...... --- const char *used_by;

Use the module * Register hostdev driver - define 'virHostdevDriverTab' and 'virHostdevDriverTabCount' - add hostdev driver register work in libvirtd.c daemonInitialize() * add hostdev driver areas to _virConnect struct _virConnect { ....... virNWFilterDriverPtr nwfilterDriver; +++ virHostdevDriverPtr hostdevDriver; ....... void * nwfilterPrivateData; +++ void * hostdevPrivateData; ....... } * add conn->hostdevDriver parser in libvirt.c: do_open() Then hypervisor drivers can get use of hostdev driver APIs. * moments that could be affacted: - domain start/shutoff - attach/detach hostdev to domain --------------------------------------------

[libvirt] [PATCH v4 1/2] Add NVRAM device
by Li Zhang 18 Apr '13

18 Apr '13

From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> For pSeries guest in QEMU, NVRAM is one kind of spapr-vio device. Users are allowed to specify spapr-vio devices'address. But NVRAM is not supported in libvirt. So this patch is to add NVRAM device to allow users to specify its address. In QEMU, NVRAM device's address is specified by "-global spapr-nvram.reg=xxxxx". In libvirt, XML file is defined as the following: <nvram> <address type='spapr-vio' reg='0x3000'/> </nvram> Signed-off-by: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> --- v4 -> v3: * Sperate NVRAM definition from qemu command line parser. v3 -> v2: * Add NVRAM in domaincommon.rng and formatdomain.xml.in suggested by Daniel P.Berrange * Add NVRAM test cases suggested by Daniel P.Berrange * Remove nvram allocation when it is not specified suggested by Daniel P.Berrange * Add several error reports suggested by Daniel P.Berrange v2 -> v1: * Add NVRAM parameters parsing in qemuParseCommandLine docs/formatdomain.html.in | 35 ++++++++++++++++++++ docs/schemas/domaincommon.rng | 10 ++++++ src/conf/domain_conf.c | 76 +++++++++++++++++++++++++++++++++++++++++++ src/conf/domain_conf.h | 10 ++++++ 4 files changed, 131 insertions(+) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index d400e35..f590304 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -4415,6 +4415,41 @@ qemu-kvm -net nic,model=? /dev/null </dl> + <h4><a name="elementsNVRAM">NVRAM device</a></h4> + <p> + One NVRAM device is always added to pSeries guests on PPC64. + And on PPC64, NVRAM devices' address type are VIO which + allows users to change.<code>nvram</code> element in XML file + is provided to specify its address. + Currently, libvirt only considers configuration for pSeries guests. + </p> + <p> + Example: usage of NVRAM configuration + </p> +<pre> + ... + <devices> + <nvram> + <address type='spapr-vio' reg='0x3000'/> + </nvram> + </devices> + ... +</pre> + <dl> + <dt><code>spapr-vio</code></dt> + <dd> + <p> + VIO device address type, this is only for PPC64. + </p> + </dd> + <dt><code>reg</code></dt> + <dd> + <p> + Devices' address + </p> + </dd> + </dl> + <h3><a name="seclabel">Security label</a></h3> <p> diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index 2c31f76..2b58d95 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -2764,6 +2764,13 @@ </optional> </element> </define> + <define name="nvram"> + <element name="nvram"> + <optional> + <ref name="address"/> + </optional> + </element> + </define> <define name="memballoon"> <element name="memballoon"> <attribute name="model"> @@ -3208,6 +3215,9 @@ <optional> <ref name="memballoon"/> </optional> + <optional> + <ref name="nvram"/> + </optional> </interleave> </element> </define> diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 36a46da..3a5e59a 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -193,6 +193,7 @@ VIR_ENUM_IMPL(virDomainDevice, VIR_DOMAIN_DEVICE_LAST, "smartcard", "chr", "memballoon", + "nvram", "rng") VIR_ENUM_IMPL(virDomainDeviceAddress, VIR_DOMAIN_DEVICE_ADDRESS_TYPE_LAST, @@ -1552,6 +1553,16 @@ void virDomainMemballoonDefFree(virDomainMemballoonDefPtr def) VIR_FREE(def);
