[libvirt] [PATCH] qemu: fix i6300esb watchdog hotplug on Q35
by Laine Stump 18 Jan '19

18 Jan '19

When commit 361c8dc17 added support for hotplugging the i6300esb watchdog device (first in libvirt-3.9.0), it accidentally contstructed the commandline for the device_add command before allocating a PCI address for the device. With no PCI address specified in the command, the watchdog would simply be placed at the lowest unused PCI slot. On a 440fx guest, this doesn't cause a problem, because libvirt's PCI address allocation algorithm would most likely give the same address anyway (usually a slot on pci-root), so nobody noticed the omission of address from the command. But on a Q35 guest, the lowest unused PCI slot is on pcie-root, which doesn't support hotplug; libvirt knows enough to assign a PCI address that is on a pcie-to-pci-bridge (because its slots *do* support hotplug), but qemu doesn't, so if there is no PCI address in the command, qemu just tries to plug the new device into pcie-root, and fails because it doesn't support hotplug, e.g.: error: Failed to attach device from watchdog.xml error: internal error: unable to execute QEMU command 'device_add': Bus 'pcie.0' does not support hotplugging The solution is simply to build the command string after assigning a PCI address, not before.

[libvirt] [PATCH v1 1/1] qemu_hotplug.c: assert disk->info.alias unique before hotplug
by Daniel Henrique Barboza 18 Jan '19

18 Jan '19

In a case where we want to hotplug the following disk: <disk type='file' device='disk'> (...) <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> In a QEMU guest that has a single OS disk, as follows: <disk type='file' device='disk'> (...) <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> What happens is that the existing guest disk will receive the ID 'scsi0-0-0-0' due to how Libvirt calculate the alias based on the address in qemu_alias.c, qemuAssignDeviceDiskAlias. When hotplugging a disk that happens to have the same address, Libvirt will calculate the same ID to it and attempt to device_add. QEMU will refuse it: $ virsh attach-device dhb hp-disk-dup.xml error: Failed to attach device from hp-disk-dup.xml error: internal error: unable to execute QEMU command 'device_add': Duplicate ID 'scsi0-0-0-0' for device And Libvirt follows it up with a cleanup code in qemuDomainAttachDiskGeneric that ends up removing what supposedly is a faulty hotplugged disk but, in this case, ends up being the original guest disk. This happens because Libvirt doesn't differentiate the error received by QMP device_add. An argument can be made for how QMP device_add should provide a different error code for this scenario. A quicker way to solve the problem is presented in this patch: let us check the generated alias against the aliases already presented in the disks in the VM definition. If a match happens, error out without calling device_add. After this patch, this is the result of the previous attach-device call: $ ./run tools/virsh attach-device dhb ~/hp-disk-dup.xml [sudo] password for danielhb: error: Failed to attach device from /home/danielhb/hp-disk-dup.xml error: operation failed: attached disk conflicts with existing device id 'scsi0-0-0-0' Reported-by: Srikanth Aithal <bssrikanth(a)in.ibm.com> Signed-off-by: Daniel Henrique Barboza <danielhb413(a)gmail.com> --- src/qemu/qemu_hotplug.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) diff --git a/src/qemu/qemu_hotplug.c b/src/qemu/qemu_hotplug.c index a1c3ca999b..7c770211ab 100644 --- a/src/qemu/qemu_hotplug.c +++ b/src/qemu/qemu_hotplug.c @@ -875,6 +875,27 @@ qemuDomainChangeEjectableMedia(virQEMUDriverPtr driver, } +/** + * qemuDomainDeviceAliasIsUnique: + * + * Searches the existing domain disks to check if a given alias is + * unique. */ +static bool +qemuDomainDeviceAliasIsUnique(virDomainDefPtr def, char *alias) +{ + int idx; + + for (idx = (def->ndisks - 1); idx >= 0; idx--) { + if (def->disks[idx]->info.alias && + (strcmp(def->disks[idx]->info.alias, alias) == 0)) { + + return false; + } + } + return true; +} + + /** * qemuDomainAttachDiskGeneric: * @@ -897,6 +918,13 @@ qemuDomainAttachDiskGeneric(virQEMUDriverPtr driver, if (qemuAssignDeviceDiskAlias(vm->def, disk, priv->qemuCaps) < 0) goto error; + if (!qemuDomainDeviceAliasIsUnique(vm->def, disk->info.alias)) { + virReportError(VIR_ERR_OPERATION_FAILED, + _("attached disk conflicts with existing " + "device id '%s'"), disk->info.alias); + goto error; + } + if (qemuDomainPrepareDiskSource(disk, priv, cfg) < 0) goto error; -- 2.20.1

[libvirt] [PATCH] rpc: virNetClientNew: fix socket leak on error path
by Nikolay Shirokovskiy 18 Jan '19

18 Jan '19

if virNetClientNew finishes with error before sock is set to client object then sock does not get unrefed. This is unexpected by function clients like virNetClientNewUNIX. Let's make sure sock gets unrefed on any error path. Next some clients like virNetClientNewLibSSH2 try to unref sock on virNetClientNew errors. This is not correct even before this patch because in some cases virNetClientNew unrefed sock on error path by itself. Let's give up sock managment to virNetClientNew entirely.

[libvirt] [PATCH] storage: More uniquely identify NPIV LUNs
by John Ferlan 18 Jan '19

18 Jan '19

https://bugzilla.redhat.com/show_bug.cgi?id=1657468 Commit be1bb6c95 changed the way volumes were stored from a forward linked list to a hash table. In doing so, it required that each vol object would have 3 unique values as keys into tables - key, name, and path. Due to how vHBA/NPIV LUNs are created/used this resulted in a failure to utilize all the LUN's found during processing. The virStorageBackendSCSINewLun uses virStorageBackendSCSISerial in order to read/return the unique serial number of the LUN to be used as a key for the volume. However, for NPIV based LUNs the logic results in usage of the same serial value for each path to the LUN. For example, $ lsscsi -tg ... [4:0:3:13] disk fc:0x207800c0ffd79b2a0xeb02ef /dev/sde /dev/sg16 [4:0:4:0] disk fc:0x50060169446021980xeb1f00 /dev/sdf /dev/sg17 [4:0:5:0] disk fc:0x50060161446021980xeb2000 /dev/sdg /dev/sg18 ... /lib/udev/scsi_id --replace-whitespace --whitelisted --device /dev/sde 3600c0ff000d7a2965c603e5401000000 /lib/udev/scsi_id --replace-whitespace --whitelisted --device /dev/sdf 350060160c460219850060160c4602198 /lib/udev/scsi_id --replace-whitespace --whitelisted --device /dev/sdg 350060160c460219850060160c4602198 The /dev/sdf and /dev/sdg although separate LUNs would end up with the same serial number used for the vol->key value. When attempting to add the LUN via virStoragePoolObjAddVol, the hash table code will indicate that we have a duplicate: virHashAddOrUpdateEntry:341 : internal error: Duplicate key and thus the LUN is not added to the pool. Digging deeper into the scsi_id output using the --export option one will find that the only difference between the two luns is: ID_TARGET_PORT=1 for /dev/sdf ID_TARGET_PORT=2 for /dev/sdg So, let's use the ID_TARGET_PORT string value along with the serial to generate a more unique key using "@serial_PORT@target_port", where @target_port is just the value of the ID_TARGET_PORT for the LUN.

Guestfish -N will now generate 1G disks instead of 100M disks by default. Virt-resize supports f2fs filesystems (Pino Toscano). libguestfs-test-tool now supports bash tab completion (Pino Toscano). The --machine-readable option now supports sending output to files or stdout/stderr. This works uniformly across most OCaml-based virt tools, specifically: virt-builder, virt-builder-repository, virt-dib, virt-get-kernel, virt-resize, virt-sparsify, and virt-v2v (Pino Toscano). Virt-builder --uninstall option now works on SUSE (Sebastian Meyer). Virt-builder now supports Windows. We are not able to ship Windows templates in the public respository for obvious licensing reasons, but if you are an MSDN subscriber you may build your own. See https://rwmj.wordpress.com/2018/09/13/creating-windows-templates-for-virt-b… Many tools now support a --key option allowing you to pass in decryption keys for filesystems stored in local files on the host rather than having to feed them in over stdin (Pino Toscano). virt-v2v and virt-p2v New -o rhv-upload mode for directly uploading images to RHV, bypassing the Export Storage Domain (Tomáš Golembiovský, Nir Soffer, Daniel Erez, Pino Toscano). New -o openstack mode for directly uploading images to OpenStack and Cinder using OpenStack APIs. Virt-v2v now has a general mechanism for input and output options: -io and -oo. Virt-v2v can now install the RHV tools or QEMU GA in guests (Tomáš Golembiovský). The huge manual has now been split into several smaller documents and is more focused on helping users to accomplish specific v2v tasks. Multiple improvements to the OVF metadata when converting to RHV (Tomáš Golembiovský, Pino Toscano, Arik Hadas). Virt-v2v can now convert Linux guests with split kernel packages, especially Ubuntu 18.04 (Pino Toscano). Virt-v2v old --password-file option has been replaced by -ip (the old option remains for backwards compatibility). Virt-v2v now preserves the VM Generation ID. Virt-v2v has a new --mac option allowing specific NICs to be mapped precisely to networks or bridges on the target. New virt-v2v --print-estimate option to estimate the size of data that virt-v2v will copy. Virt-v2v is now usually able to remove open-vm-tools and VMware Tools from the Linux guest during conversion (Pino Toscano). Virt-v2v can now support UEFI conversions to RHV (Tomáš Golembiovský). Virt-p2v now prefers you to shut down instead of rebooting the machine after conversion has finished (Pino Toscano). Virt-v2v now writes the libosinfo short ID to the libvirt metadata when using -o local and -o libvirt output modes (Martin Kletzander). Language bindings OpenJDK 10+ is supported (Pino Toscano). Java bindings fixed for Gentoo host (Martin Kletzander). Inspection Support Kali Linux (Pino Toscano). When inspecting mountpoints, look for /etc/mdadm/mdadm.conf as well as /etc/mdadm.conf (Nikolay Ivanets). Improved support for OpenSUSE Tumbleweed (Pino Toscano). Architectures and platforms Miscellaneous macOS build fixes (Adam Robinson). Other Multiple documentation typos fixed (Yuri Chornoivan). Security See also guestfs-security(1). CVE-2018-11806 Qemu's slirp (userspace networking) had several buffer overflows which could be triggered from the guest or network side. API New APIs "f2fs_expand" Expand an f2fs filesystem (Pino Toscano). "inspect_get_osinfo" Get the libosinfo short ID for the inspected guest (Pino Toscano). "lvm_scan" This rescans all PVs, VGs and LVs, optionally activating them. Other API changes "part_get_mbr_part_type" was reimplemented in OCaml (Nikolay Ivanets). "list_filesystems" now filters out MBR extended partitions (Nikolay Ivanets). "vgscan" has been deprecated. Use the new "lvm_scan" API in preference. Build changes The JSON library switched from yajl to Jansson ≥ 2.7 (Pino Toscano). Support for The Sleuth Kit 4.5 (Pino Toscano). Multiple improvements in the "./configure" script (Lin Ma). More out-of-tree build fixes (Hilko Bengen). Some work on reproducible builds (Bernhard M. Wiedemann). Internals lvmetad is now used unconditionally, and is started much earlier in the appliance boot process. This fixes support for certain PV types. On Debian, dash is installed inside the appliance and in virt-rescue (Pino Toscano). The amount of RAM assigned to the appliance has been increased from 500M to 768M (on x86_64, other architectures have different limits). This enables use of up to 255 disks when using recent Linux kernels. Virt-v2v now models the source machine type (eg. i440FX, Q35 or virt). Virt-p2v now generates configuration code automatically, also code for parsing the kernel command line. Use "LT_INIT" instead of "AC_PROG_LIBTOOL". The OCaml "JSON" code for parsing and serializing has been unified into a single abstract data type. Most OCaml tools are now built using the PIC runtime. This has a performance penalty on i686, but is relatively free on other architectures and has security benefits. The direct backend now queries the qemu binary for availability of KVM, instead of using a heuristic based on /dev/kvm (Andrea Bolognani). Our "clever" libxml2 writer macros are now used consistently across all parts of the code base. Qemu dropped -nodefconfig without telling us. The equivalent -no-user-config option is now used instead. Qemu also moved the "serial" option from -drive to -device, again without any notice, and this is also fixed.

[libvirt] [PATCH RFC 00/51] refactor block job handling and add support for new event/commands (blockdev-add saga)
by Peter Krempa 17 Jan '19

17 Jan '19

This series refactors how libvirt stores block job data and handles block job events in general. This is done in preparation for -blockdev support where we'll need to add support for the 'blockdev-create' job which is not associated to any frontend 'disk' in some cases. This series introduces a new structure and table of blockjobs currently running and implements handlers for the new even "JOB_STATUS_CHANGE". RFC status excuses: - the series needs much more testing than I did - the last few patches are true RFC - I didn't port/refactor the rest of the blockjob finishing code that I have for the individual job types after the big refactor so there aren't any examples for the -blockdev case yet. I'll post the link to a repo containing the patches some time later.

[libvirt] [PATCH 0/5] network: fix networking for firewalld+nftables
by Laine Stump 17 Jan '19

17 Jan '19

The detailed explanation of this is in Patch 4/5. Basically, when firewalld enables their new nftables backend, libvirt virtual networks lose all ability to forward packets from guests out to the physical network, and can only communicate with the host itself as much as firewalld's "public" zone will allow (which isn't much, and doesn't include DHCP or DNS). Laine Stump (5): docs: add forgotten mentions of forward mode "open" util: move all firewalld-specific stuff into its own file util: new function virFirewallDInterfaceSetZone() network: regain guest network connectivity after firewalld switch to nftables network: allow configuring firewalld zone for virtual network bridge device docs/formatnetwork.html.in | 21 ++- docs/news.xml | 40 ++++++ docs/schemas/basictypes.rng | 6 + docs/schemas/network.rng | 6 + include/libvirt/virterror.h | 1 + libvirt.spec.in | 16 +++ src/conf/network_conf.c | 14 +- src/conf/network_conf.h | 1 + src/libvirt_private.syms | 4 + src/network/Makefile.inc.am | 10 +- src/network/bridge_driver_linux.c | 25 ++++ src/network/libvirt.zone | 14 ++ src/util/Makefile.inc.am | 2 + src/util/virerror.c | 1 + src/util/virfirewall.c | 86 +----------- src/util/virfirewalld.c | 151 +++++++++++++++++++++ src/util/virfirewalld.h | 36 +++++ src/util/virfirewallpriv.h | 2 - tests/networkxml2xmlin/routed-network.xml | 2 +- tests/networkxml2xmlout/routed-network.xml | 2 +- tests/virfirewalltest.c | 1 + 21 files changed, 350 insertions(+), 91 deletions(-) create mode 100644 src/network/libvirt.zone create mode 100644 src/util/virfirewalld.c create mode 100644 src/util/virfirewalld.h -- 2.20.1

From: Li XueLei <li.xuelei1(a)zte.com.cn> During making disk snapshot in an active domain, sometimes we should update the domain's persistent definition.We must check if the domain is defined, before we update the persistent definition file.

[libvirt] [PATCH 0/6] RFC: qemu: virtio-{non-}transitional support
by Cole Robinson 16 Jan '19

16 Jan '19

This series adds the beginnings of support for virtio-transitional and virtio-non-transitional qemu devices. qemu patches, queued for qemu 4.0.0: https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg00923.html Previous libvirt discussion around this: https://www.redhat.com/archives/libvir-list/2018-August/msg01073.html Long story short we need to expose these options so apps have a usable way to support rhel6 + virtio + q35. This series only covers exposing the associated device models for disk and rng devices to make sure I'm on the right track. serial, net, scsi, input-host, balloon 9p, vsock, vhost-scsi still need to be implemented. Those should follow the rng example, except vhost-scsi may need to be a different approach. The main RFC bits here are: * The disk approach. danpb and I briefly discussed on IRC adding new bus= values vs a new model= attribute. We decided model= is the lesser of two evils, since bus= handling in apps is tied with target= generation, so adding new virtio-X bus= values will cause more work for apps. These patches add a <disk model=X/> attribute * The XML and naming. Previous discussions seemed to favor adding new model-style values rather than a 'transitional' attribute or similar. So these patches add model='virtio-transitional' and model='virtio-non-transitional' * The PCI address handling. I just mapped virtio-non-transitional to imply plain PCI addressing. I think that's all we need but I'm not positive so I'd appreciate a review of that approach.

[libvirt] [PATCH v2] util: audit: Fix logging an error when kernel lacks audit support
by Erik Skultety 16 Jan '19

16 Jan '19

Based on an upstream discussion, reporting the errno is useful for the user to know why audit isn't supported. Even though having an error in the logs might look concerning when 'audit_log=1', it also denotes that audit is only going to be used if it's available, continuing normally if it's unavailable for whatever reason.

[libvirt] [PULL v2 03/49] hw/misc/ivshmem: Remove deprecated "ivshmem" legacy device
by Michael S. Tsirkin 15 Jan '19

15 Jan '19

From: Thomas Huth <thuth(a)redhat.com> It's been marked as deprecated in QEMU v2.6.0 already, so really nobody should use the legacy "ivshmem" device anymore (but use ivshmem-plain or ivshmem-doorbell instead). Time to remove the deprecated device now. Belatedly also update a mention of the deprecated "ivshmem" in the file docs/specs/ivshmem-spec.txt to "ivshmem-doorbell". Missed in commit 5400c02b90b ("ivshmem: Split ivshmem-plain, ivshmem-doorbell off ivshmem").

[libvirt] Release of libvirt-5.0.0
by Daniel Veillard 15 Jan '19

15 Jan '19

Hi all, as planned I just tagged the new release in git, and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ I also pushed the python bindings, identical to 4.10 with just the versioning bump, you can find them at: ftp://libvirt.org/libvirt/python/ This release includes new features, but also remove the old apparently unused UML driver support. There is also a rather large set of improvements: New features: - Xen: Add support for openvswitch The libxl driver now supports virtual interfaces that connect to an openvswitch bridge, including interfaces with VLAN tagging and trunking configuration. - qemu: Report whether KVM nesting is available Running nested KVM guests requires specific configuration steps to be performed on the host; libvirt will now report in the host capabilities whether KVM nesting support is available. Removed features: - Drop UML driver The UML driver was unmaintained and not tested for quite some time now. Worse, there is a bug that causes it to deadlock on some very basic operations (e.g. dumping domain XML). These facts make us believe no one uses it. Improvements: - qemu: Add support for ARMv6l guests - Support more NVDIMM configuration options Introduce more configuration options. For the source element, add the 'alignsize' and 'pmem' subelements. For the target element, add the 'readonly' subelement. - cpu: Add support for "stibp" x86_64 feature Add cpu flag stibp (Single Thread Indirect Branch Predictors) to prevent indirect branch predictions from being controlled by the sibling Hyperthread. - libxl: Handle external domain destroy Historically, if a domain was destroyed using xl rather than through libvirt APIs, libvirt would not be aware of the fact and keep considering it as running. This is no longer the case. - Start selecting the first available DRI device for OpenGL operations If OpenGL support is needed (either with SPICE gl enabled or with egl-headless), libvirt is now able to pick the first available DRI device for the job. At the same time, this improvement is also a bugfix as it prevents permission-related issues with regards to our mount namespaces and the default DRI render node's permissions which would normally prevent QEMU from accessing such a device. - qemu: Add support for postcopy-requests migration statistics The virDomainJobInfo can get number page requests received from the destination host during post-copy migration. Bug fixes: - lxc: Don't forbid interfaces with type=direct Such interfaces are supported by lxc and should be allowed. - qemu: Fully clean up RNG devices on detach Some RNG device types, such as those using EGD, might need extra clean up on the host in addition to removing the guest-side device. Thanks everybody for your help toward this release, be it with patches reviews, bug description, documentation and localizations ! As a reminder, the next release is scheduled at the end of February, in the meantime, enjoy the new release !

[libvirt] [PULL 03/44] hw/misc/ivshmem: Remove deprecated "ivshmem" legacy device
by Michael S. Tsirkin 15 Jan '19

15 Jan '19

From: Thomas Huth <thuth(a)redhat.com> It's been marked as deprecated in QEMU v2.6.0 already, so really nobody should use the legacy "ivshmem" device anymore (but use ivshmem-plain or ivshmem-doorbell instead). Time to remove the deprecated device now. Belatedly also update a mention of the deprecated "ivshmem" in the file docs/specs/ivshmem-spec.txt to "ivshmem-doorbell". Missed in commit 5400c02b90b ("ivshmem: Split ivshmem-plain, ivshmem-doorbell off ivshmem").

[libvirt] [PATCH] util: make forgotten changes suggested during review of commit d40b820c

I had intended to make these changes to commit d40b820c before pushing, but forgot about it during the day between the initial review and ACK. Neither change is significant - just returning immediately when virNetDevGetName() faills (instead of logging a debug message first) and eliminating a comment that adds to confusion rather than eliminating it.

[libvirt] Entering freeze for libvirt-5.0.0
by Daniel Veillard 13 Jan '19

13 Jan '19

As planned I tagged the RC1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ I didn't see the 5 patches from Laine in git at that point but those seems to be bug + portability fixes anyway so it should still be possible to have them in say before rc2. Seems to be working fine in my limited testing, and CI seems to be mostly green excepot a few edge cases https://ci.centos.org/view/libvirt/ so that's looking good to me, but as usual it's good to exercice the RCs in various condition to make sure we didn't introdue regressions on some platforms. I plan on RC2 release during the week-end and then if everything goes well push 5.0.0 out on Tuesday for Jan 15 deadline, thanks in advance for giving it some testing !

[libvirt] [PATCH v5 00/36] BaselineHypervisorCPU using QEMU QMP exchanges
by Chris Venteicher 12 Jan '19

12 Jan '19

Some architectures (S390) depend on QEMU to compute baseline CPU model and expand a models feature set. Interacting with QEMU requires starting the QEMU process and completing one or more query-cpu-model-baseline QMP exchanges with QEMU in addition to a query-cpu-model-expansion QMP exchange to expand all features in the model. See "s390x CPU models: exposing features" patch set on Qemu-devel for discussion of QEMU aspects. This is part of resolution of: https://bugzilla.redhat.com/show_bug.cgi?id=1511999 ----- This patch set fixes all process code issues identified here: https://www.redhat.com/archives/libvir-list/2018-November/msg00349.html in patches 1-22 of the series. The remaining patches implement the BaselineHypervisorCPU changes using the non-domain qemu process code. The process changes (patches 1-22)... - Make the process code generic (not capabilities specific) for use by BaselineHypervisorCPU - Many of the process patches are simple code moves with implementation changes in other distinct patches - A thread safe library function creates a unique directory under libDir for each QEMU process (for QMP messaging) to decouple processes in terms of sockets and file system footprint. The BaselineHypervisorCPU changes (patches 22-36)... - Fix all issues raised in patch sets 1-4.

[libvirt] [PATCH] qemu: require reply from guest agent in qemuAgentGetInterfaces
by Ján Tomko 10 Jan '19

10 Jan '19

Since its introduction in commit 0977b8aa071 (released in v1.2.14) qemuAgentGetInterfaces calls qemuAgentCommand with needReply=false, which allows qemuAgentCommand to return 0 even when it did not get any reply from the agent. Set needReply to true, since we dereference it right after. This can be hit if libvirt is waiting for an event from the agent (e.g. shutdown) and the agent cannot reply in time (e.g. due to the guest being shut down), as reported in: https://bugzilla.redhat.com/show_bug.cgi?id=1663051 Signed-off-by: Ján Tomko <jtomko(a)redhat.com> --- src/qemu/qemu_agent.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/qemu/qemu_agent.c b/src/qemu/qemu_agent.c index 0f4dae37e3..80b789b5e0 100644 --- a/src/qemu/qemu_agent.c +++ b/src/qemu/qemu_agent.c @@ -2043,7 +2043,7 @@ qemuAgentGetInterfaces(qemuAgentPtr mon, if (!(cmd = qemuAgentMakeCommand("guest-network-get-interfaces", NULL))) goto cleanup; - if (qemuAgentCommand(mon, cmd, &reply, false, + if (qemuAgentCommand(mon, cmd, &reply, true, VIR_DOMAIN_QEMU_AGENT_COMMAND_BLOCK) < 0) goto cleanup; -- 2.20.1

[libvirt] [PATCH] cpu_map: Add support for arch-capabilities feature
by Jiri Denemark 10 Jan '19

10 Jan '19

The feature was added to QEMU in 3.1.0 and it is currently blocking migration, which is expected to change in the future. Luckily 3.1.0 is new enough to give us migratability hints on each feature via query-cpu-model-expension, which means we don't need to use the "migratable" attribute on the CPU map XML.

[libvirt] [RFC] UEFI and NVRAM store file format
by Nikolay Shirokovskiy 10 Jan '19

10 Jan '19

Hi, all. There is old patch series [1] to add file format to UEFI and NVRAM. It is not merged because I guess it is intended to be used with online internal snapshot and such snapshot have issues with nvram. First it can save VM state in nvram image. Second nvram is saved as part of VM state so one doesn't need to make nvram image snapshot as QEMU does. This is explained in greater details in [2]. But offline internal snapshots and disk only snapshots makes sense. So what about finally take the patch series.

Happy New Year everybody, as planned we should release 5.0.0 around Jan 15. This means that the best to meet that deadline would be to enter freeze tomorrow Thur, then have an RC2 over the w.e. and then if all goes well we can roll out the release next Tuesday. If there is no issue with this plan I will then release RC1 tomorrow probably in the evening european time, thanks, Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH v2] network: remove stale function
by Laine Stump 10 Jan '19

10 Jan '19

networkMigrateStateFiles was added nearly 5 years ago when the network state directory was moved from /var/lib/libvirt to /var/run/libvirt just prior to libvirt-1.2.4). It was only required to maintain proper state information for networks that were active during an upgrade that didn't involve rebooting the host. At this point the likelyhood of anyone upgrading their libvirt from pre-1.2.4 directly to 5.0.0 or later *without rebooting the host* is probably so close to 0 that no properly informed bookie would take *any* odds on it happening, so it seems appropriate to remove this pointless code.

[libvirt] [PATCH v2 0/6] Allow adding mountOpts to the storage pool mount command
by John Ferlan 09 Jan '19

09 Jan '19

v1: https://www.redhat.com/archives/libvir-list/2018-December/msg00558.html Kept the subject the same, but the concept has been adjusted to follow issues pointed out by jtomko vis-a-vis allowing arbitrary options via XML. This series adds both the NFS and the RBD adjustments that were essentially in the referenced series from review. Changes since v1: * Patch 1: (NEW) Implements a bare-bones infrastructure for storage pool XML namespace. Could be split again, but separately the patches were too small IMO. * Patch 2: (NEW) Implementation of providing XML Namespace functions. The details of the operation are in the subsequent patch. I could combine 2 and 3, but perhaps it's easier to review separated. * Patch 3: (REWORK) Rework the previous series patch1 in order to utilize the Storage Pool XML Namespace. Adjust the description of the configuration and modify the storagepoolxml2xmltest appropriately. * Patch 4: (REWORK) Utilize the XML Namespace data to generate the command line which doesn't change since v1. * Patch 5: (REWORK) Rework the virsh code in order to generate the proper syntax to utilize Storage Pool XML Namespaces. * Patch 6: (NEW) Well, new as in this series, but it's essentially a rework of what was posted in the series jtomko referenced. The code will "prove" (to a degree) that the concept can work for multiple pool types. The "downside" is that there's no (easy) way that I could find to generate output to show the commands are executed.

[libvirt] [PATCH 0/4] util: Fixing libvirt errors on cavium/thunder-nicvf
by Radoslaw Biernacki 09 Jan '19

09 Jan '19

ThunderX is Cavium SoC. This platform contain SRIOV NIC. Unlike other commonly known network devices it does not have VF functionality duplicated in its PF. PF is purely management device (on HW level). This creates several problems with existing libvirt code as in many places libvirt assumes that each VF netdev has PF netdev assigned. This patch series trying to address issues which can be easily fixed. (mostly bug fixes found while working on full featured solution) First patch in series is most important as it allows to unblock the netdev detection and use <hostdev> on this platform. More details about those issues can be found at: https://bugs.linaro.org/show_bug.cgi?id=3778 https://bugs.launchpad.net/charm-nova-compute/+bug/1771662 Radoslaw Biernacki (4): util: fixing wrong assumption that PF has to have netdev assigned util: Code simplification util: Fix for NULL dereference util: Fixing invalid error checking from virPCIGetNetname() src/qemu/qemu_domain_address.c | 11 ++--- src/util/virhostdev.c | 2 +- src/util/virnetdev.c | 50 ++++---------------- 3 files changed, 16 insertions(+), 47 deletions(-) -- 2.14.1

[libvirt] [PATCH 0/3] Fix examples/ under mingw
by Eric Blake 09 Jan '19

09 Jan '19

My recent patch to make all of the examples work independently of gnulib worked fine on Linux, but failed on mingw: https://travis-ci.org/libvirt/libvirt/jobs/476898635 The whole point of gnulib is to work around portability pitfalls so we don't have to bend over backwards thinking about it in our code; and it would be possible to fix this bug by linking the problematic example binaries against gnulib after all. But since the examples are still small and self-contained enough that using manual workarounds wasn't too daunting, that's the approach I took here. I'm pushing this series as a build-breaker fix in a couple of hours, or sooner if I get a review.

[libvirt] [PATCH] qemu: Use ULL instead of uint64_t for RDMA GID event
by Michal Privoznik 09 Jan '19

09 Jan '19

In the previous commit we are using uint64_t for storing subnet prefix and interface id that qemu reports in RDMA_GID_STATUS_CHANGED event. We also report them in some debug messages. This poses a problem because uint64_t can be UL or ULL depending on the host architecture and hence we wouldn't know which format to use. Switch to ULL which is big enough and doesn't suffer from the issue.

[libvirt] [PATCH v3 RESEND] qemu: Process RDMA GID state change event
by Yuval Shaia 09 Jan '19

09 Jan '19

This event is emitted on the monitor when a GID table in pvrdma device is modified and the change needs to be propagate to the backend RDMA device's GID table. The control over the RDMA device's GID table is done by updating the device's Ethernet function addresses. Usually the first GID entry is determine by the MAC address, the second by the first IPv6 address and the third by the IPv4 address. Other entries can be added by adding more IP addresses. The opposite is the same, i.e. whenever an address is removed, the corresponding GID entry is removed. The process is done by the network and RDMA stacks. Whenever an address is added the ib_core driver is notified and calls the device driver's add_gid function which in turn update the device. To support this in pvrdma device we need to hook into the create_bind and destroy_bind HW commands triggered by pvrdma driver in guest. Whenever a changed is made to the pvrdma device's GID table a special QMP messages is sent to be processed by libvirt to update the address of the backend Ethernet device.

I noticed from IRC that Travis has been failing builds since our Jan 1 update of gnulib. I'm not sure what changed in the gnulib files to trip up clang, and I'm not really set up to test that this fixes the problem seen by Travis (it works locally for me using gcc - but gcc wasn't seeing the failure), but the ideas in the patch make sense. So, unless there is an easy way to make Travis run on candidate patches, I'll wait for a review rather than pushing this as a build-breaker.

[libvirt] [PATCH 0/3] Rebase LXC network definition to support version 3.0

The series propose a new way to define NICs inside LXC native. It is needed because LXC version 3.X uses indexes to define NICs and the current algorithm is not able to support them.

[libvirt] [PATCH RFC] qemu: caps: invalidate kvm capable qemu binaries on every restart
by Nikolay Shirokovskiy 04 Jan '19

04 Jan '19

If qemu binary exposes kvm then caps depends heavily on host state. We are already check explicitly some host features - kernel version, microcode version, nested flag state. This won't nesserily help if somebody change CPU on host. Let's instead invalidate such caps on every daemon restart. This makes kernel version and microcode version check excessive but nested flag is still need to be checked. Cache invalidating on restart is archived by keeping list of binaries that whose caps cache was validated at least once. If binary in not yet validated and supports kvm then we need to invalidate it's caps cache.

[libvirt] configuration support to allow devices into cgroup devices devices.list inside libvirt_lxc container
by Mohan R 02 Jan '19

02 Jan '19

Hi, I was having trouble with losetup inside libvirt_lxc container. Then I found that <mknod state="on"> will provide CAP_MKNOD capability. Even after enabling CAP_MKNOD in my container, I was not able to do 'losetup' because cgroup's device.list for my container dont have 'rwm' flags for loop devices ('b 7:* rwm' in /sys/fs/cgroup/devices/machine.slice/machine- lxc*.scope/user/*/c1.session/devices.list) Currently I have to manually do echo "b 7:* rwm" into /sys/fs/cgroup/devices/machine.slice/machine-lxc*.scope/devices.allow file before I login into the container in order to use loop devices. It will be useful if we have a way to do this through domain xml rather than manually doing it like what I'm doing now. I looked into rng files, but I'm not able to find a way to define 'b 7:* rwm' in xml. I just want to check with the devs if this is possible already. Otherwise I'll file one improvement bug. I think lxc already have a way to do this through lxc.cgroup.devices.allow Thanks, Mohan R

[libvirt] [PATCH v2 RESEND] qemu: Process RDMA GID state change event
by Yuval Shaia 24 Dec '18

24 Dec '18

This event is emitted on the monitor when a GID table in pvrdma device is modified and the change needs to be propagate to the backend RDMA device's GID table. The control over the RDMA device's GID table is done by updating the device's Ethernet function addresses. Usually the first GID entry is determine by the MAC address, the second by the first IPv6 address and the third by the IPv4 address. Other entries can be added by adding more IP addresses. The opposite is the same, i.e. whenever an address is removed, the corresponding GID entry is removed. The process is done by the network and RDMA stacks. Whenever an address is added the ib_core driver is notified and calls the device driver's add_gid function which in turn update the device. To support this in pvrdma device we need to hook into the create_bind and destroy_bind HW commands triggered by pvrdma driver in guest. Whenever a changed is made to the pvrdma device's GID table a special QMP messages is sent to be processed by libvirt to update the address of the backend Ethernet device.

[libvirt] [PATCH v3] qemu: Process RDMA GID state change event
by Yuval Shaia 23 Dec '18

23 Dec '18

This event is emitted on the monitor when a GID table in pvrdma device is modified and the change needs to be propagate to the backend RDMA device's GID table. The control over the RDMA device's GID table is done by updating the device's Ethernet function addresses. Usually the first GID entry is determine by the MAC address, the second by the first IPv6 address and the third by the IPv4 address. Other entries can be added by adding more IP addresses. The opposite is the same, i.e. whenever an address is removed, the corresponding GID entry is removed. The process is done by the network and RDMA stacks. Whenever an address is added the ib_core driver is notified and calls the device driver's add_gid function which in turn update the device. To support this in pvrdma device we need to hook into the create_bind and destroy_bind HW commands triggered by pvrdma driver in guest. Whenever a changed is made to the pvrdma device's GID table a special QMP messages is sent to be processed by libvirt to update the address of the backend Ethernet device.

[libvirt] [PATCH v5 00/11] update NVDIMM support
by Luyao Zhong 22 Dec '18

22 Dec '18

Hi libvirt experts, There are some gaps between qemu and libvirt, libvirt has not supported several config options about NVDIMM memory while qemu has now, including 'align', 'pmem', 'unarmed'. So these three options is introduced in this patch set. The 'align' and 'unarmed' was renamed to 'alignsize' and 'readonly' in domain xml file for user-friendly definition. Regards, Luyao Zhong Luyao Zhong (11): nvdimm: introduce 'alignsize' element into xml for NVDIMM memory nvdimm: introduce 'pmem' element into xml for NVDIMM memory nvdimm: introduce 'readonly' element into xml for NVDIMM memory qemu_capabilities: introduce QEMU_CAPS_OBJECT_MEMORY_FILE_ALIGN qemu_capabilities: introduce QEMU_CAPS_OBJECT_MEMORY_FILE_PMEM qemu_capabilities: introduce QEMU_CAPS_DEVICE_NVDIMM_UNARMED nvdimm: use DO_TEST_CAPS_LATEST to do nvdimm qemuxml2argvdata test nvdimm: qemu command-line generating for align property nvdimm: qemu command-line generating for pmem property nvdimm: qemu command-line generating for unarmed property nvdimm: update news.xml docs/formatdomain.html.in | 80 +++++++++++++--- docs/news.xml | 9 ++ docs/schemas/domaincommon.rng | 23 ++++- src/conf/domain_conf.c | 57 ++++++++++-- src/conf/domain_conf.h | 3 + src/qemu/qemu_capabilities.c | 16 +++- src/qemu/qemu_capabilities.h | 5 + src/qemu/qemu_command.c | 44 ++++++++- src/qemu/qemu_command.h | 3 +- src/qemu/qemu_hotplug.c | 2 +- .../caps_2.10.0.x86_64.replies | 62 ++++++++----- tests/qemucapabilitiesdata/caps_2.10.0.x86_64.xml | 2 +- .../caps_2.11.0.x86_64.replies | 62 ++++++++----- tests/qemucapabilitiesdata/caps_2.11.0.x86_64.xml | 2 +- tests/qemucapabilitiesdata/caps_2.12.0.aarch64.xml | 1 + tests/qemucapabilitiesdata/caps_2.12.0.ppc64.xml | 1 + tests/qemucapabilitiesdata/caps_2.12.0.s390x.xml | 1 + .../caps_2.12.0.x86_64.replies | 78 ++++++++++------ tests/qemucapabilitiesdata/caps_2.12.0.x86_64.xml | 3 +- .../qemucapabilitiesdata/caps_2.6.0.x86_64.replies | 46 ++++++--- tests/qemucapabilitiesdata/caps_2.6.0.x86_64.xml | 2 +- .../qemucapabilitiesdata/caps_2.7.0.x86_64.replies | 46 ++++++--- tests/qemucapabilitiesdata/caps_2.7.0.x86_64.xml | 2 +- .../qemucapabilitiesdata/caps_2.8.0.x86_64.replies | 46 ++++++--- tests/qemucapabilitiesdata/caps_2.8.0.x86_64.xml | 2 +- .../qemucapabilitiesdata/caps_2.9.0.x86_64.replies | 62 ++++++++----- tests/qemucapabilitiesdata/caps_2.9.0.x86_64.xml | 2 +- tests/qemucapabilitiesdata/caps_3.0.0.ppc64.xml | 1 + tests/qemucapabilitiesdata/caps_3.0.0.riscv32.xml | 1 + tests/qemucapabilitiesdata/caps_3.0.0.riscv64.xml | 1 + tests/qemucapabilitiesdata/caps_3.0.0.s390x.xml | 1 + .../qemucapabilitiesdata/caps_3.0.0.x86_64.replies | 103 +++++++++++++++------ tests/qemucapabilitiesdata/caps_3.0.0.x86_64.xml | 4 +- tests/qemucapabilitiesdata/caps_3.1.0.ppc64.xml | 2 + .../qemucapabilitiesdata/caps_3.1.0.x86_64.replies | 102 ++++++++++++++------ tests/qemucapabilitiesdata/caps_3.1.0.x86_64.xml | 5 +- .../memory-hotplug-nvdimm-access.args | 31 ------- ...memory-hotplug-nvdimm-access.x86_64-latest.args | 36 +++++++ .../memory-hotplug-nvdimm-align.x86_64-latest.args | 36 +++++++ .../memory-hotplug-nvdimm-align.xml | 58 ++++++++++++ .../memory-hotplug-nvdimm-label.args | 31 ------- .../memory-hotplug-nvdimm-label.x86_64-latest.args | 36 +++++++ .../memory-hotplug-nvdimm-pmem.x86_64-latest.args | 36 +++++++ .../memory-hotplug-nvdimm-pmem.xml | 58 ++++++++++++ ...mory-hotplug-nvdimm-readonly.x86_64-latest.args | 36 +++++++ .../memory-hotplug-nvdimm-readonly.xml | 58 ++++++++++++ tests/qemuxml2argvdata/memory-hotplug-nvdimm.args | 31 ------- .../memory-hotplug-nvdimm.x86_64-latest.args | 36 +++++++ tests/qemuxml2argvtest.c | 15 ++- .../memory-hotplug-nvdimm-align.xml | 1 + .../memory-hotplug-nvdimm-pmem.xml | 1 + .../memory-hotplug-nvdimm-readonly.xml | 1 + tests/qemuxml2xmltest.c | 3 + 53 files changed, 1047 insertions(+), 339 deletions(-) delete mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-access.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-access.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-align.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-align.xml delete mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-label.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-label.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-pmem.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-pmem.xml create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-readonly.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-readonly.xml delete mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm.x86_64-latest.args create mode 120000 tests/qemuxml2xmloutdata/memory-hotplug-nvdimm-align.xml create mode 120000 tests/qemuxml2xmloutdata/memory-hotplug-nvdimm-pmem.xml create mode 120000 tests/qemuxml2xmloutdata/memory-hotplug-nvdimm-readonly.xml -- 2.7.4

[libvirt] [PATCH 0/9] qemu: sav/restore inactive persistent config
by Nikolay Shirokovskiy 21 Dec '18

21 Dec '18

This series address the same issue as seemingly abandomed patch series [1]. Implementation is written from scratch however as I don't see need to introduce new flags for the purpose of this patch series. However I read John's comments and addressed them where applied. The option for not reverting inactive config in case of restoring active persistent domain that Jiri suggested in [2] is new functionality actually and is left for future work. The purpuse of patch series is described in patch 3 "qemu: snapshot: save/restore inactive persistent config": In case of active persistent domain snapshot metadata is not complete. We save only active configuration and on restore use it both for active and inactive configuration. Let's fix it and save and restore both in this case.

[libvirt] [PATCH v2] qemu: Introduce caching whether /dev/kvm is accessible
by Marc Hartmayer 21 Dec '18

21 Dec '18

Introduce caching whether /dev/kvm is usable as the QEMU user:QEMU group. This reduces the overhead of the QEMU capabilities cache lookup. Before this patch there were many fork() calls used for checking whether /dev/kvm is accessible. Now we store the result whether /dev/kvm is accessible or not and we only need to re-run the virFileAccessibleAs check if the ctime of /dev/kvm has changed. Suggested-by: Daniel P.

[libvirt] [PATCH v2 0/2] qemu: fix misc noisy logs for optional storage sources
by Nikolay Shirokovskiy 21 Dec '18

21 Dec '18

John, I still did not add anything to formatdomain.html.in because when I gave this a thought it looks odd to add something like "we don't get stats for missing storage source" - it is obvious because such getting stats is simply not possible. It you feel there is need to add something to the docs then please help me formulate it and we include it in the patch(es) on pushing. Nikolay Diff from v1: ============ - add error logs examples to commit messages - add notices at INFO level of handling optional disks with missing sources in a special way - comment why handling such cases in a special manner in code - check for cold_boot flag in qemuProcessPrepareHostStorage Nikolay Shirokovskiy (2): qemu: don't log error for missing optional storage sources on stats qemu: don't log error for missing optional storage sources on start src/qemu/qemu_domain.c | 9 +++++++++ src/qemu/qemu_domain.h | 3 +++ src/qemu/qemu_driver.c | 14 ++++++++++++++ src/qemu/qemu_process.c | 10 +++++++++- 4 files changed, 35 insertions(+), 1 deletion(-) -- 1.8.3.1

[libvirt] CfP for VHPC ‘19: HPC Virtualization Paper Registration due January 25, 2019 - 14th Virtualization in High-Performance Cloud Computing Workshop@ISC
by VHPC 19 20 Dec '18

20 Dec '18

Please accept our apologies if you receive multiple copies of this Call for Papers ==================================================================== CALL FOR PAPERS 14th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '19) held in conjunction with the International Supercomputing Conference - High Performance, June 16-20, 2019, Frankfurt, Germany. (Springer LNCS Proceedings) ==================================================================== Date: June 20, 2019 Workshop URL: http://vhpc.org Abstract Submission Deadline: January 25, 2019 Springer LNCS, rolling abstract submission Abstract/Paper Submission Link: https://edas.info/newPaper.php?c=25685 Call for Papers Containers and virtualization technologies constitute key enabling factors for flexible resource management in modern data centers, and particularly in cloud environments. Cloud providers need to manage complex infrastructures in a seamless fashion to support the highly dynamic and heterogeneous workloads and hosted applications customers deploy. Similarly, HPC environments have been increasingly adopting techniques that enable flexible management of vast computing and networking resources, close to marginal provisioning cost, which is unprecedented in the history of scientific and commercial computing. Various virtualization-containerization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple underutilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization (i.e., containerization), with its capability to isolate multiple user-space environments and to allow for their coexistence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; lastly, unikernels provide for many virtualization benefits with a minimized OS/library surface. I/O Virtualization in turn allows physical network interfaces to take traffic from multiple VMs or containers; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology is furthermore enabling virtualization of HPC infrastructures. Publication Accepted papers will be published in a Springer LNCS proceedings volume. Topics of Interest The VHPC program committee solicits original, high-quality submissions related to virtualization across the entire software stack with a special focus on the intersection of HPC, containers-virtualization and the cloud.

From: Thomas Huth <thuth(a)redhat.com> They've been deprecated for two releases and nobody complained that they are still required anymore, so it's time to remove these now. And while we're at it, mark the other remaining old 0.x machine types as deprecated (since they can not properly be used for live-migration anyway).

This would make existing VMs that are runnable with pc-q35-3.1.0 not runnable by only updating the machine-type. The good news is that we can make this a non-issue by clearly documenting that QEMU needs a more recent kernel (just like we'll do for RDTSCP[1]).

[libvirt] [PATCH 0/2] AMD SEV: Relabel session data under /var/lib/libvirt
by Erik Skultety 19 Dec '18

19 Dec '18

If a user tries to pass the optional "dhCert" or "session" data to the SEV firmware, these are in form of a base64-encoded strings which libvirt then takes and creates files with those strings as content under /var/lib/libvirt/qemu/<domain>. Libvirt then puts paths to these files on to QEMU cmdline. QEMU then uses these files within its communication with SEV firmware, provided it has access to those files. https://bugzilla.redhat.com/show_bug.cgi?id=1658112 Erik Skultety (2): qemu: process: SEV: Assume libDir to be the directory to create files in qemu: process: SEV: Relabel guest owner's SEV files created before start src/qemu/qemu_process.c | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) -- 2.19.2
