[libvirt] [PATCH V2] tests: xmconfigtest: add tests for cmdline formating
by Jim Fehlig 05 Jun '18

05 Jun '18

Commit 656151bf fixed formatting of the <cmdline> element. Perhaps it would have been noticed and fixed earlier if we had a test. With this change, all possible cases of formating <cmdline> from xmconfig are covered 1. no 'extra=' or 'root=' in xm.cfg 2. 'extra=' but no 'root=' in xm.cfg 3. 'root=' but no 'extra=' in xm.cfg 4. both 'root=' and 'extra=' in xm.cfg Case 1 is covered by all existing paravirt tests since they have no 'extra=' or 'root='. Case 2 is covered by adding 'extra=' to a few of the existing paravirt tests. Cases 3 and 4 are covered by new tests that only test conversion of xm.cfg to xml.

[libvirt] [PATCH] nwfilter: directly use poll to wait for packets instead of pcap_next
by Daniel P. Berrangé 04 Jun '18

04 Jun '18

When a QEMU VM shuts down its TAP device gets deleted while nwfilter IP address learning thread is still capturing packets. It is seen that with TPACKET_V3 support in libcap, the pcap_next() call will not always exit its poll() when the NIC is removed. This prevents the learning thread from exiting which blocks the rest of libvirtd waiting on mutex acquisition. By switching to do poll() in libvirt code, we can ensure that we always exit the poll() at a time that is right for libvirt. Signed-off-by: Daniel P.

[libvirt] Release of libvirt-4.4.0
by Daniel Veillard 04 Jun '18

04 Jun '18

It's finally out, tagged in git, with signed tarball and rpms at the usual place: ftp://libvirt.org/libvirt/ I also made a 4.4.0 release for the python bindings that one can find at ftp://libvirt.org/libvirt/python/ There is apparently more new features than improvements, and no bug fix in this release, I would just guess that people don't feel like updating news.xml on bug fixes, rather than no bug needing fixes for a full month. It may still be a good idea to update to this release and not just for the fun of testing new features ! New features: bhyve: Support locking guest memory Bhyve's guest memory may be wired using the <memoryBacking><locked/></memoryBacking> element. qemu: Provide VFIO channel I/O passthrough support Support passthrough devices that use channel I/O based mechanism in a QEMU virtual machine. qemu: Add support for migration of VMs with non-shared storage over TLS It's now possible to use the VIR_MIGRATE_TLS flag together with VIR_MIGRATE_NON_SHARED_DISK. The connection is then secured using the TLS environment which is setup for the migration connection. Add support for VM Generation ID The VM Generatation ID exposes a 128-bit, cryptographically random, integer value identifier, referred to as a Globally Unique Identifier (GUID) to the guest in order to notify the guest operating system when the virtual machine is executed with a different configuration. Add a new domain XML processing and a domain capabilities feature. Introduce virDomainDetachDeviceAlias This new API enables users to detach device using only its alias. Introduce new virConnectCompareHypervisorCPU and virConnectBaselineHypervisorCPU APIs Unlike the old virConnectCompareCPU and virConnectBaselineCPU APIs, both new APIs consider capabilities of a specific hypervisor. Introduce SCSI persistent reservations support The QEMU driver gained support for qemu-pr-helper which enables guests to issue SCSI commands for persistent reservation. qemu: Implement multiple screen support for virDomainScreenshot While the virDomainScreenshot API supported multihead video cards, the implementation was missing. But now that QEMU implemented it libvirt has done as well. qemu: add support for vhost-vsock-device A new vsock device was introduced, allowing communication between the guest and the host via the AF_VSOCK family. Improvements: qemu: Add suport for OpenGL rendering with SDL Domains using SDL as a graphics backend will now be able to use OpenGL accelerated rendering. qemu: Add support for 'output' audio codec Support QEMU's 'hda-output' codec advertising only a line-out for ich6 and ich9 sound devices. virsh: Enhance event name completion Implement event name completion for some commands (e.g. event, secret-event, pool-event and nodedev-event) Thanks for everybody who contributed to that feature rich release, be it with code, ideas, reviews etc ... Hopefully it won't crash and burn, Enjoy and Banzai !

[libvirt] [PATCH] qemu: check for QEMU_CAPS_DEVICE_VHOST_VSOCK
by Ján Tomko 04 Jun '18

04 Jun '18

My commit b8b42ca added support for formatting the vsock command line without actually checking if it's supported. Add it to the per-device validation function. https://bugzilla.redhat.com/show_bug.cgi?id=1291851 Reported-by: John Ferlan <jferlan(a)redhat.com> Signed-off-by: Ján Tomko <jtomko(a)redhat.com> --- src/qemu/qemu_domain.c | 20 +++++++++++++++++++- tests/qemuxml2xmltest.c | 4 ++-- 2 files changed, 21 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index 2c51e4c0d8..474bef0ec9 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -5283,6 +5283,21 @@ qemuDomainDeviceDefValidateMemory(const virDomainMemoryDef *memory ATTRIBUTE_UNU } +static int +qemuDomainDeviceDefValidateVsock(const virDomainVsockDef *vsock ATTRIBUTE_UNUSED, + virQEMUCapsPtr qemuCaps) +{ + if (!virQEMUCapsGet(qemuCaps, QEMU_CAPS_DEVICE_VHOST_VSOCK)) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("vsock device is not supported " + "with this QEMU binary")); + return -1; + } + + return 0; +} + + static int qemuDomainDeviceDefValidate(const virDomainDeviceDef *dev, const virDomainDef *def, @@ -5342,6 +5357,10 @@ qemuDomainDeviceDefValidate(const virDomainDeviceDef *dev, ret = qemuDomainDeviceDefValidateMemory(dev->data.memory, def); break; + case VIR_DOMAIN_DEVICE_VSOCK: + ret = qemuDomainDeviceDefValidateVsock(dev->data.vsock, qemuCaps); + break; + case VIR_DOMAIN_DEVICE_LEASE: case VIR_DOMAIN_DEVICE_FS: case VIR_DOMAIN_DEVICE_INPUT: @@ -5354,7 +5373,6 @@ qemuDomainDeviceDefValidate(const virDomainDeviceDef *dev, case VIR_DOMAIN_DEVICE_TPM: case VIR_DOMAIN_DEVICE_PANIC: case VIR_DOMAIN_DEVICE_IOMMU: - case VIR_DOMAIN_DEVICE_VSOCK: case VIR_DOMAIN_DEVICE_NONE: case VIR_DOMAIN_DEVICE_LAST: break; diff --git a/tests/qemuxml2xmltest.c b/tests/qemuxml2xmltest.c index 5671114de0..fdb3d2946b 100644 --- a/tests/qemuxml2xmltest.c +++ b/tests/qemuxml2xmltest.c @@ -1212,8 +1212,8 @@ mymain(void) DO_TEST_STATUS("migration-out-params"); DO_TEST_STATUS("migration-out-nbd-tls"); - DO_TEST("vhost-vsock", NONE); - DO_TEST("vhost-vsock-auto", NONE); + DO_TEST("vhost-vsock", QEMU_CAPS_DEVICE_VHOST_VSOCK); + DO_TEST("vhost-vsock-auto", QEMU_CAPS_DEVICE_VHOST_VSOCK); if (getenv("LIBVIRT_SKIP_CLEANUP") == NULL) virFileDeleteTree(fakerootdir); -- 2.16.1
