[PATCH v2] i386: Deprecate the -no-hpet QEMU command line option
by Thomas Huth 03 Jan '23

03 Jan '23

The HPET setting has been turned into a machine property a while ago already, so we should finally do the next step and deprecate the legacy CLI option, too. Signed-off-by: Thomas Huth <thuth(a)redhat.com> --- v2: - Rebased to current version from master branch / adjusted version info - Dropped the descrpition in hw/i386/pc.c (already done via another patch) Note: The "hpet" property should now show up in the output of the "query-command-line-options" QMP command since commit 2f129fc107b4a, so it should be feasible for libvirt now to properly probe for the property . docs/about/deprecated.rst | 6 ++++++ softmmu/vl.c | 1 + qemu-options.hx | 2 +- 3 files changed, 8 insertions(+), 1 deletion(-) diff --git a/docs/about/deprecated.rst b/docs/about/deprecated.rst index 93affe3669..2ae6a79b21 100644 --- a/docs/about/deprecated.rst +++ b/docs/about/deprecated.rst @@ -114,6 +114,12 @@ form is preferred.

[PATCH V3 0/7] qemu: support updating device's bootindex
by Jiang Jiacheng 24 Dec '22

24 Dec '22

Support updating device's(support cdrom, disk and network) bootindex online in virDomainUpdateDeviceFlags. The new bootindex will take effect after guest rebooting. Enable bootindex can be set to 0, it means cancel the device's bootindex. To use this feature, we need to get the device's xml first and modify the boot order in the xml, then use 'virsh update-device <domain> <xml> --flag' to update the bootindex. Note that the flag should be --config or --persistent if the vm is running. Jiang Jiacheng (7): qemu: Introduce qemuDomainChangeBootIndex to update device's bootindex qemu: Marking a device's bootindex can be changed qemu: check the bootIndex could be changed or not qemu: Support update disk's bootindex qemu: Support update net's bootindex qemu: Support set bootindex to 0 to cancel bootindex setting test: add a test for bootIndex = 0 provided by the user diff to v2: * improve function description and commit message * move functions in qemu_conf.c to qemu_domain.c * add a test for bootindex = 0 provided by user * fix a bug in logical of checking bootindex src/conf/device_conf.h | 3 + src/conf/domain_conf.c | 10 ++- src/conf/domain_postparse.c | 8 ++- src/conf/schemas/domaincommon.rng | 2 +- src/qemu/qemu_conf.c | 41 +++++++++++ src/qemu/qemu_conf.h | 5 ++ src/qemu/qemu_domain.c | 69 +++++++++++++++++- src/qemu/qemu_domain.h | 9 +++ src/qemu/qemu_driver.c | 32 +++++++++ src/qemu/qemu_hotplug.c | 17 +++-- src/qemu/qemu_monitor.c | 12 ++++ src/qemu/qemu_monitor.h | 6 ++ src/qemu/qemu_monitor_json.c | 22 ++++++ src/qemu/qemu_monitor_json.h | 6 ++ tests/qemuxml2argvdata/boot-order-set-0.xml | 72 +++++++++++++++++++ tests/qemuxml2xmloutdata/boot-order-set-0.xml | 72 +++++++++++++++++++ tests/qemuxml2xmltest.c | 1 + 17 files changed, 376 insertions(+), 11 deletions(-) create mode 100644 tests/qemuxml2argvdata/boot-order-set-0.xml create mode 100644 tests/qemuxml2xmloutdata/boot-order-set-0.xml -- 2.33.0

[PATCH] qemu: implement QEMU NBD source reconnect delay attribute
by Christian Nautze 23 Dec '22

23 Dec '22

Currently it's only possible to set this parameter during domain creation via QEMU commandline passthrough feature. With the new delay attribute it's also possible to set this parameter if you want to attach a new NBD disk using "virsh attach-device domain device.xml" e.g.: <disk type='network' device='disk'> <driver name='qemu' type='raw'/> <source protocol='nbd' name='foo'> <host name='example.org' port='6000'/> <reconnect enabled='yes' delay='10'/> </source> <target dev='vdb' bus='virtio'/> </disk> Signed-off-by: Christian Nautze <christian.nautze(a)exoscale.ch> --- docs/formatdomain.rst | 10 ++++++-- src/conf/domain_conf.c | 19 +++++++++++++++ src/conf/schemas/domaincommon.rng | 3 +++ src/conf/schemas/storagecommon.rng | 5 ++++ src/conf/storage_source_conf.c | 1 + src/conf/storage_source_conf.h | 4 ++++ src/qemu/qemu_block.c | 4 +++- src/qemu/qemu_domain.c | 9 ++++++++ .../disk-network-nbd.x86_64-latest.args | 23 +++++++++++-------- tests/qemuxml2argvdata/disk-network-nbd.xml | 8 +++++++ tests/qemuxml2xmloutdata/disk-network-nbd.xml | 9 ++++++++ 11 files changed, 82 insertions(+), 13 deletions(-) diff --git a/docs/formatdomain.rst b/docs/formatdomain.rst index d7fffc6e0b..3fbeba644a 100644 --- a/docs/formatdomain.rst +++ b/docs/formatdomain.rst @@ -2938,13 +2938,19 @@ paravirtualized driver is specified via the ``disk`` element. are intended to be default, then the entire element may be omitted. ``reconnect`` For disk type ``vhostuser`` configures reconnect timeout if the connection - is lost.

Whiles working on Hyper-V patches I've posted yesterday I ran domaincapstest occasionally and was puzzled for a moment that qemu-7.2.0 wasn't tested. Well it is, but it's harder to see immediately because individual test cases are in 'random' order: 11) qemu_7.2.0.x86_64 ... OK .... 46) qemu_5.1.0.sparc ... OK 47) qemu_6.1.0.x86_64 ... OK 48) qemu_6.1.0-q35.x86_64 ... OK 49) qemu_6.1.0-tcg.x86_64 ... OK 50) qemu_7.0.0.ppc64 ... OK 51) qemu_6.2.0.x86_64 ... OK 52) qemu_6.2.0-q35.x86_64 ... OK 53) qemu_6.2.0-tcg.x86_64 ... OK Huge thanks to Martin, who helped me realize (in 2/3) that 'struct dirent' while declared as 'char d_name[256]' is rather peculiar and a little dance is needed to copy it properly.

[PATCH] virQEMUDriverGetDomainCapabilities: Validate machine type
by Michal Privoznik 22 Dec '22

22 Dec '22

When calling virConnectGetDomainCapabilities() (exposed as virsh domcapabilities) users have option to specify whatever sub-set of { emulatorbin, arch, machine, virttype } they want. Then we have a logic (hidden in virQEMUCapsCacheLookupDefault()) that picks qemuCaps that satisfy values passed by user. And whatever was not specified is then set to the default value as specified by picked qemuCaps. For instance: if no machine type was provided but emulatorbin was, then the machine type is set to the default one as defined by the emulatorbin. Or, when just virttype was set then the remaining three values are set to their respective defaults. Except, we have a crasher in this case: # virsh domcapabilities --virttype hvf error: Disconnected from qemu:///system due to end of file error: failed to get emulator capabilities error: End of file while reading data: Input/output error This is because for 'hvf' virttype (at least my) QEMU does not have any machine type. Therefore, @machine is set to NULL and the rest of the code does not expect that.

[RFC PATCH 0/1] secret: Inhibit shutdown for ephemeral secrets
by Michal Privoznik 20 Dec '22

20 Dec '22

I'm kind of convinced that we want to do this, but also it's a significant change in the behaviour of the daemon, hence RFC prefix. This stemmed from a discussion with a user who wants us to use something more secure than base64 encoded secret values stored on a disk. They suggested storing the values in TPM and while that might sound like a good idea, I suggested using ephemeral secrets for the time being. Well, because of '--timeout 120', ephemeral secrets are short lived, indeed. Meanwhile, let me see if there's a library we could use to talk to TPM.

Setting SELinux label on TPM state during migration
by Michal Prívozník 19 Dec '22

19 Dec '22

Stefan, as you saw, I'm trying to implement support for migration with TPM state on a shared volume. I mean, it is working when the shared volume is an NFS mount point because NFS does not really propagate SELinux labels, but rather has this 'virt_use_nfs' sebool which effectivelly allows all svirt_t processes to access NFS (thus including swtpm). But things get trickier when a distributed FS that knows SELinux properly (e.g. ceph) is used instead. What I am currently struggling with is - finding the sweet spot when the source swtpm has let go of the state and the destination has not accessed it (because if it did it would get EPERM). Bottom line - the SELinux label is generated dynamically on each guest startup (to ensure its uniqueness on the system). Therefore, the label on the destination is different to the one on the source. The behavior I'm seeing now is: 1) the source starts migration: {"execute":"migrate","arguments":{"detach":true,"resume":false,"uri":"fd:migrate"},"id":"libvirt-428"} 2) the destination does not touch the swtpm state right away, but when the TPM state comes in the migration stream, it is touched. Partial logs from the destination: -> {"execute":"migrate-incoming","arguments":{"uri":"tcp:[::]:49152"},"id":"libvirt-415"} <- {"timestamp": {"seconds": 1671449778, "microseconds": 500164}, "event": "MIGRATION", "data": {"status": "setup"}}] <- {"return": {}, "id": "libvirt-415"} <- {"timestamp": {"seconds": 1671449778, "microseconds": 732358}, "event": "MIGRATION", "data": {"status": "active"}} Now, before QEMU sends MIGRATION status:completed, I can see QEMU accessing the TPM state: Thread 1 "qemu-kvm" hit Breakpoint 1, tpm_emulator_set_state_blob (tpm_emu=0x5572af389cb0, type=1, tsb=0x5572af389db0, flags=0) at ../backends/tpm/tpm_emulator.c:796 796 { (gdb) bt #0 tpm_emulator_set_state_blob (tpm_emu=0x5572af389cb0, type=1, tsb=0x5572af389db0, flags=0) at ../backends/tpm/tpm_emulator.c:796 #1 0x00005572acf21fe5 in tpm_emulator_post_load (opaque=0x5572af389cb0, version_id=<optimized out>) at ../backends/tpm/tpm_emulator.c:868 #2 0x00005572acf25497 in vmstate_load_state (f=0x5572af512a10, vmsd=0x5572ad7743b8 <vmstate_tpm_emulator>, opaque=0x5572af389cb0, version_id=1) at ../migration/vmstate.c:162 #3 0x00005572acf45753 in qemu_loadvm_state_main (f=0x5572af512a10, mis=0x5572af39b4e0) at ../migration/savevm.c:876 #4 0x00005572acf47591 in qemu_loadvm_state (f=0x5572af512a10) at ../migration/savevm.c:2712 #5 0x00005572acf301f6 in process_incoming_migration_co (opaque=<optimized out>) at ../migration/migration.c:591 #6 0x00005572ad400976 in coroutine_trampoline (i0=<optimized out>, i1=<optimized out>) at ../util/coroutine-ucontext.c:177 #7 0x00007f64ca22a360 in ??

() This in turn means that swtpm on the destination is going to CMD_INIT itself while the source is still using it. I wonder what we can do about this. Perhaps - postpone init until the time the vCPUs on the destination are resumed? That way libvirt on the source could restore labels (effectively cut the source swtpm process off the TPM state), then libvirtd on the destination could set the label and 'cont'. If 'cont' fails for whatever reason then the source libvirtd would just set the label on the TPM state and everything is back to normal.

Libvirt support for qemu reconnect flag
by Miguel Ping 19 Dec '22

19 Dec '22

Hello, Qemu has support for reconnect-delay parameter, that allows for the qemu nbd client to retry failed NBD operations. This is useful if you are running a custom NBD server and want to update the server without failing requests. Unfortunately, the only way to supply these flags is at domain creation via qemu commandline passthrough feature [1]; there is no way to supply them when eg hotpluggin a disk via eg: "virsh attach-device ..." Is there interest in libvirt for a patch that supports qemu "reconnect delay" param? What would be the best way to move forward with such a patch? I think the param can be supported in either the device definition (eg: the <reconnect enabled='yes' timeout='10'/> option already exists for disk type="vhostuser"), or globally via the qemu.conf configuration file. Thank you for your time [1] https://libvirt.org/kbase/qemu-passthrough-security.html#xml-document-addit…

[libvirt PATCH 00/30] introduce external snapshot delete support

14 Dec '22

This implements virDomainSnapshotDelete API to support external snapshots.

[PATCH] virnuma: Allow multiple nodes for preferred policy
by Michal Privoznik 14 Dec '22

14 Dec '22

In the past, the preferred policy (VIR_DOMAIN_NUMATUNE_MEM_PREFERRED) required exactly one (host) NUMA node. This made sense because: 1) the libnuma API - numa_set_preferred() allowed exactly one node, because 2) corresponding kernel syscall (__NR_set_mempolicy) accepted exactly one node (for MPOL_PREFERRED mode). But things have changed since then. Firstly, kernel introduced new MPOL_PREFERRED_MANY mode (v5.15-rc1~107^2~21) which was then exposed in libnuma as numa_set_preferred_many() (v2.0.15~24). Fortunately, libnuma also exposes numa_has_preferred_many() which returns whether the kernel has support for the new mode (1) or not (0). Putting this all together, we can lift our check for sufficiently new kernel and libnuma.
