[libvirt PATCH] qemu: format 'ramfb' attribute for mediated devices
by Jonathon Jongsma 23 Jun '20

23 Jun '20

It's possible to use ramfb as the boot display of an assigned vgpu device. This was introduced in 4b95738c, but unfortunately the attribute was not formatted into the xml output for such a device. This patch fixes that oversight and adds a xml2xml test to verify proper behavior. https://bugzilla.redhat.com/show_bug.cgi?id=1847791 Signed-off-by: Jonathon Jongsma <jjongsma(a)redhat.com> --- src/conf/domain_conf.c | 3 ++ ...stdev-mdev-display-ramfb.x86_64-latest.xml | 44 +++++++++++++++++++ .../hostdev-mdev-display-ramfb.xml | 33 ++++++++++++++ tests/qemuxml2xmltest.c | 1 + 4 files changed, 81 insertions(+) create mode 100644 tests/qemuxml2xmloutdata/hostdev-mdev-display-ramfb.x86_64-latest.xml create mode 100644 tests/qemuxml2xmloutdata/hostdev-mdev-display-ramfb.xml diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index e9336fd72d..e942dc41ae 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -28312,6 +28312,9 @@ virDomainHostdevDefFormat(virBufferPtr buf, if (mdevsrc->display != VIR_TRISTATE_SWITCH_ABSENT) virBufferAsprintf(buf, " display='%s'", virTristateSwitchTypeToString(mdevsrc->display)); + if (mdevsrc->ramfb != VIR_TRISTATE_SWITCH_ABSENT) + virBufferAsprintf(buf, " ramfb='%s'", + virTristateSwitchTypeToString(mdevsrc->display)); } } diff --git a/tests/qemuxml2xmloutdata/hostdev-mdev-display-ramfb.x86_64-latest.xml b/tests/qemuxml2xmloutdata/hostdev-mdev-display-ramfb.x86_64-latest.xml new file mode 100644 index 0000000000..c134400486 --- /dev/null +++ b/tests/qemuxml2xmloutdata/hostdev-mdev-display-ramfb.x86_64-latest.xml @@ -0,0 +1,44 @@ +<domain type='qemu'> + <name>QEMUGuest2</name> + <uuid>c7a5fdbd-edaf-9455-926a-d65c16db1809</uuid> + <memory unit='KiB'>219136</memory> + <currentMemory unit='KiB'>219136</currentMemory> + <vcpu placement='static'>1</vcpu> + <os> + <type arch='i686' machine='pc'>hvm</type> + <boot dev='hd'/> + </os> + <cpu mode='custom' match='exact' check='none'> + <model fallback='forbid'>qemu64</model> + </cpu> + <clock offset='utc'/> + <on_poweroff>destroy</on_poweroff> + <on_reboot>restart</on_reboot> + <on_crash>destroy</on_crash> + <devices> + <emulator>/usr/bin/qemu-system-i386</emulator> + <controller type='usb' index='0' model='piix3-uhci'> + <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x2'/> + </controller> + <controller type='pci' index='0' model='pci-root'/> + <controller type='ide' index='0'> + <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> + </controller> + <input type='mouse' bus='ps2'/> + <input type='keyboard' bus='ps2'/> + <graphics type='vnc' port='-1' autoport='yes'> + <listen type='address'/> + </graphics> + <video> + <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1' primary='yes'/> + <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> + </video> + <hostdev mode='subsystem' type='mdev' managed='no' model='vfio-pci' display='on' ramfb='on'> + <source> + <address uuid='53764d0e-85a0-42b4-af5c-2046b460b1dc'/> + </source> + <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> + </hostdev> + <memballoon model='none'/> + </devices> +</domain> diff --git a/tests/qemuxml2xmloutdata/hostdev-mdev-display-ramfb.xml b/tests/qemuxml2xmloutdata/hostdev-mdev-display-ramfb.xml new file mode 100644 index 0000000000..6fdc477ca2 --- /dev/null +++ b/tests/qemuxml2xmloutdata/hostdev-mdev-display-ramfb.xml @@ -0,0 +1,33 @@ +<domain type='qemu'> + <name>QEMUGuest2</name> + <uuid>c7a5fdbd-edaf-9455-926a-d65c16db1809</uuid> + <memory unit='KiB'>219136</memory> + <currentMemory unit='KiB'>219136</currentMemory> + <vcpu placement='static'>1</vcpu> + <os> + <type arch='i686' machine='pc'>hvm</type> + <boot dev='hd'/> + </os> + <clock offset='utc'/> + <on_poweroff>destroy</on_poweroff> + <on_reboot>restart</on_reboot> + <on_crash>destroy</on_crash> + <devices> + <emulator>/usr/bin/qemu-system-i386</emulator> + <controller type='usb' index='0'> + </controller> + <controller type='pci' index='0' model='pci-root'/> + <controller type='ide' index='0'> + </controller> + <graphics type='vnc'/> + <hostdev mode='subsystem' type='mdev' model='vfio-pci' display='on' ramfb='on'> + <source> + <address uuid='53764d0e-85a0-42b4-af5c-2046b460b1dc'/> + </source> + </hostdev> + <video> + <model type='qxl' heads='1'/> + </video> + <memballoon model='none'/> + </devices> +</domain> diff --git a/tests/qemuxml2xmltest.c b/tests/qemuxml2xmltest.c index 022f6786b9..e3919821af 100644 --- a/tests/qemuxml2xmltest.c +++ b/tests/qemuxml2xmltest.c @@ -529,6 +529,7 @@ mymain(void) QEMU_CAPS_VFIO_PCI_DISPLAY, QEMU_CAPS_DEVICE_VFIO_PCI, QEMU_CAPS_VNC); + DO_TEST_CAPS_LATEST("hostdev-mdev-display-ramfb"); DO_TEST("pci-rom", NONE); DO_TEST("pci-rom-disabled", NONE); DO_TEST("pci-rom-disabled-invalid", NONE); -- 2.21.3

[libvirt PATCH 00/23] remove use of terms 'whitelist'/'blacklist' and 'master'/'slave'
by Daniel P. Berrangé 23 Jun '20

23 Jun '20

The terms "whitelist" / "blacklist" perpetuate the notion that white is good and black is bad[1]. Their usage is trivially eliminated from libvirt with a variety of alternative terms. The replacements are more applicable to the usage context in most cases. The only exceptions are • Libvirt needs to keep "seccomp-blacklist" back compat for running guest capabilities on upgrade • kmod uses "blacklist" for modprobe config file key The terms "master" / "slave" have inescapable historical context that makes them a bad choice for metaphors in software[1]. Again there are a variety of alternatives that can be used, many of which are more applicable to the usage context. Eliminating all usage though is not practical, due to libvirt's need to interface with external systems, where the terminology is part of the formal API. The unfixable exceptions are: • Libvirt uses slave=NNN master=NNN in XML schema for FreeBSD nmdm devs • Linux kernel sysfs uses "slave_$NIC" for bonding NIC members • Linux kernel mount options MS_SLAVE for mount propagation • QEMU uses "slave" in many device/property names • Jenkins website calls the libvirt plugin "libvirt-slave" • VirtualBox uses 'Slave' in many config file attributes Note, this doesn't attempt to remove cases of the word "master" which are used in isolation, only those paired with usage of the word "slave". Remaining usage of "master" needs evaluating, as some of these contexts are none the less implicitly associated with the "master/slave" concept. Nothing in the po/ directory is updated. This will be updated when we refresh translations at time of freeze. There should be no functional change in any of these patches with the exception of the patch tweaking matching for NICs in the interface driver. [1] There are many docs on the web covering this in detail, with one fairly clear description being: https://tools.ietf.org/id/draft-knodel-terminology-00.html Daniel P.

[libvirt PATCH] qemu: don't continue loading caps if outdated
by Daniel P. Berrangé 22 Jun '20

22 Jun '20

The XML format used for QEMU capabilities is not required to be stable across releases, as we invalidate the cache whenever the libvirt binary changes. We none the less always try to parse te entire XML file before we do any validity checks. Thus if we change the format of any part of the data, or change permitted values for enums, then libvirtd logs will be spammed with errors. These are not in fact errors, but an expected scenario. This change makes the loading code validate the cache timestamp against the libvirtd timestamp immediately. If they don't match then we stop loading the rest of the XML file. Signed-off-by: Daniel P.

For panel discussions, all panelists will receive a complimentary event pass. TECHNICAL TALKS A good technical talk should not just report on what has happened over the last year; it should present a concrete problem and how it impacts the user and/or developer community. Whenever applicable, focus on work that needs to be done, difficulties that haven't yet been solved, and on decisions that other developers should be aware of. Summarizing recent developments is okay but it should not be more than a small portion of the overall talk. END-USER TALKS One of the big challenges as developers is to know what, where and how people actually use our software. We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using KVM in production you are encouraged submit a speaking proposal. Simply mark it as an end-user talk. As an end user, this is a unique opportunity to get your input to developers. PANEL DISCUSSIONS If you are proposing a panel discussion, please make sure that you list all of your potential panelists in your the abstract. We will request full biographies if a panel is accepted. HANDS-ON / BOF SESSIONS We will reserve some time for people to get together and discuss strategic decisions as well as other topics that are best solved within smaller groups. These sessions will be announced during the event. If you are interested in organizing such a session, please add it to the list at http://www.linux-kvm.org/page/KVM_Forum_2020_BOF Let people you think who might be interested know about your BOF, and encourage them to add their names to the wiki page as well. Please add your ideas to the list before KVM Forum starts. HOTEL / TRAVEL -------------- This year's event will take place at the Conference Center Dublin. For information on hotels close to the conference, please visit https://events.linuxfoundation.org/kvm-forum/attend/venue-travel/. Information on conference hotel blocks will be available later in Spring 2020.

[PATCH 00/32] qemu: backup: Rewrite/simplify internals and document semantics
by Peter Krempa 22 Jun '20

22 Jun '20

Simplify how we approach bitmap handling to increase robustness and understanding of the code. Additionally document intricacies of how we approach handling of bitmaps so that in cases when users decide to do snapshots outside of libvirt they can re-create the bitmaps so that they will still work with backups (requires new qemu-img). I'll also follow up documenting implicationsof blockjobs on bitmaps later. To fetch this including a commit which allows testing: git fetch https://gitlab.com/pipo.sk/libvirt.git checkpoint-rewrite-and-document This doesn't require any special qemu patches. Note that this shares many patches from my previous posting which tried to make use of 'block-dirty-bitmap-populate', but keeps explicit bitmap tracking for now. We'll be able to revisit use of the blockjob if the qemu work will continue somehow.

[libvirt PATCH] ci: Use fedora image for code style checking

Centos does not have the cppi package, so some code style checks are skipped. Switch to a fedora image to do the code style checks.

[RFC PATCH 00/41] qemu: Rewrite checkpoint code for 'block-dirty-bitmap-populate'
by Peter Krempa 22 Jun '20

22 Jun '20

Use 'block-dirty-bitmap-populate' and change how we create bitmaps corresponding to checkpoints to simplify the code and also properly integrate with backing chain images created outside of libvirt. This patchset changes how we approach checkpoints by keeping one bitmap per checkpoint and disk and not propagating the bitmaps into overlays on snapshots. This massively simplifies the code handling all the operations during blockjobs and backups. While the change isn't compatible with checkpoints created previously, we didn't yet enable the support for checkpoints/backups. Note that 'block-dirty-bitmap-populate' is _not_ in finished state in qemu yet, so I'm posting this as RFC and as reference for qemu developers of the usefulnes of it. The changes can be fetched by: git fetch https://gitlab.com/pipo.sk/libvirt.git checkpoint-bitmap-populate Note that the above branch also contains a commit enabling incremental backup for simpler testing. I've pushed the appropriate qemu patches for convenience here: git fetch https://gitlab.com/pipo.sk/qemu.git block-dirty-bitmap-populate Peter Krempa (41): virErrorPreserveLast: Return the saved error object in addition to storing it util: error: Introduce VIR_ERROR_AUTOPRESERVE_LAST macro qemuBackupDiskDataCleanup: Use VIR_ERROR_AUTO_PRESERVE_LAST qemu: backup: Split up code traversing checkpoint list looking for bitmaps qemu: backup: Fix backup of disk skipped in an intermediate checkpoint conf: backup: Store incremental backup checkpoint name per-disk qemu: backup: Move fetching of checkpoint list for incremental backup qemublocktest: Add 'empty' test case for bitmaps qemublocktest: Add 'empty' case for incremental backup test qemublocktest: Add 'empty' case for checkpoint deletion qemublocktest: Add 'empty' case for blockcopy bitmap handling test qemublocktest: Add 'empty' case for checkpoint bitmap handling qemublocktest: Disable testcases for all bitmap handling qemublocktest: Delete 'synthetic' bitmap test cases qemublocktest: Extract printing of nodename list qemu: checkpoint: Don't chain bitmaps for checkpoints qemublocktest: Replace 'basic' bitmap detection test case data qemu: snapshot: Don't propagate bitmaps to upper layers qemublocktest: Replace 'snapshots' bitmap detection test case data qemuBlockBitmapChainIsValid: Adjust to new semantics of bitmaps qemublocktest: Re-add bitmap validation for 'basic' and 'snapshots' cases qemublocktest: Add new 'synthetic' bitmap detection and validation test case qemu: checkpoint: Don't merge checkpoints during deletion qemublocktest: Rename TEST_CHECKPOINT_DELETE_MERGE to TEST_CHECKPOINT_DELETE qemublocktest: Re-introduce testing of checkpoint deletion qemucapabilitiestest: Bump qemu-5.1 caps on x86_64 for 'dirty-bitmap-populate' qemu: monitor: Add support for 'block-dirty-bitmap-populate' transaction member qemuDomainStorageSourcePrivate: Add per-source private blockjob qemu: blockjob: Introduce 'populate' blockjob qemu: domain: Introduce helper for always fetching virStorageSource private data qemu: block: Add helper to add temporary block bitmaps from allocation maps qemu: block: Add universal helper for merging dirty bitmaps for all scenarios qemu: backup: Rewrite backup bitmap handling to the new bitmap semantics qemublocktest: Add 'basic' tests for backup bitmap handling qemublocktest: Add 'snapshots' tests for backup bitmap handling qemu: Rewrite bitmap handling for block commit qemublocktest: Add 'basic' tests for commit bitmap handling qemublocktest: Add 'snapshots' tests for block commit bitmap handling qemu: blockjob: Remove 'disabledBitmapsBase' field from commit job private data qemu: Rewrite bitmap handling for block copy qemublocktest: Add test cases for handling bitmaps during block-copy src/conf/backup_conf.c | 8 + src/conf/backup_conf.h | 1 + src/qemu/qemu_backup.c | 221 +- src/qemu/qemu_backup.h | 13 +- src/qemu/qemu_block.c | 674 ++-- src/qemu/qemu_block.h | 35 +- src/qemu/qemu_blockjob.c | 182 +- src/qemu/qemu_blockjob.h | 16 +- src/qemu/qemu_checkpoint.c | 174 +- src/qemu/qemu_checkpoint.h | 1 -
