[PATCH] Qemu: migration: Not bind RAM info with active migration status
by Keqian Zhu 07 Jan '21

07 Jan '21

For that Qemu supports returning incoming migration info since its commit 65ace0604551 (migration: add postcopy total blocktime into query-migrate), which may contains active status, but without RAM info. Drop this binding relationship check in libvirt.

[PATCH v2] conf: Add support for keeping TPM emulator state
by Eiichi Tsukata 07 Jan '21

07 Jan '21

Currently, swtpm TPM state file is removed when a transient domain is powered off or undefined. When we store TPM state on a shared storage such as NFS and use transient domain, TPM states should be kept as it is. Add per-TPM emulator option `persistent_sate` for keeping TPM state. This option only works for the emulator type backend and looks as follows: <tpm model='tpm-tis'> <backend type='emulator' persistent_state='yes'/> </tpm> Signed-off-by: Eiichi Tsukata <eiichi.tsukata(a)nutanix.com> Reviewed-by: Stefan Berger <stefanb(a)linux.ibm.com> --- docs/formatdomain.rst | 7 ++++ docs/schemas/domaincommon.rng | 12 ++++++ src/conf/domain_conf.c | 21 ++++++++++ src/conf/domain_conf.h | 1 + src/qemu/qemu_tpm.c | 3 +- ...pm-emulator-tpm2-pstate.x86_64-latest.args | 38 +++++++++++++++++++ .../tpm-emulator-tpm2-pstate.xml | 30 +++++++++++++++ tests/qemuxml2argvtest.c | 1 + ...tpm-emulator-tpm2-pstate.x86_64-latest.xml | 37 ++++++++++++++++++ tests/qemuxml2xmltest.c | 1 + 10 files changed, 150 insertions(+), 1 deletion(-) create mode 100644 tests/qemuxml2argvdata/tpm-emulator-tpm2-pstate.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/tpm-emulator-tpm2-pstate.xml create mode 100644 tests/qemuxml2xmloutdata/tpm-emulator-tpm2-pstate.x86_64-latest.xml diff --git a/docs/formatdomain.rst b/docs/formatdomain.rst index 512939679b..87bbd1a4f1 100644 --- a/docs/formatdomain.rst +++ b/docs/formatdomain.rst @@ -6986,6 +6986,13 @@ Example: usage of the TPM Emulator - '1.2' : creates a TPM 1.2 - '2.0' : creates a TPM 2.0 +``persistent_state`` + The ``persistent_state`` attribute indicates whether 'swtpm' TPM state is + kept or not when a transient domain is powered off or undefined.

[RFC] exposing 'nodedev assigned to domain' info to users
by Daniel Henrique Barboza 06 Jan '21

06 Jan '21

Hi, This is something I've been giving a thought after working in Gitlab issue #72 and decided to run through the ML before hitting the code. We don't have an easy way to retrieve the domain that is using an specific hostdev. Let's say that I want to know which domain is using the PCI card pci_0000_01_00_2. 'nodedev-dumpxml' will return the hardware/driver capabilities of the device, such as IOMMU group, driver and so on, but will not inform which domain is using the hostdev, if any. 'nodedev-list' will simply list all nodedev names known to Libvirt, without outputting any other information. IIUC, the only existing way I can reliably tell whether a hostdev is being used by domain, aside from having to register the information by myself during domain definition of course, is via 'virsh dumpxml <domain>' each existing running domain and matching the nodedev name with the source.address element of the XML. When we consider SR-IOV devices that can have 28+ VFs each (and have lots of fun caveats, like Github #72 showed us), the capability of hot plug/unplug hostdevs freely, and lots of running domains, it is clear that we're putting a considerable pressure in the upper layers (OVirt, or a poor human admin) to keep track of the nodedevs each running domain is using. An info that we already have internally and can just expose it. I have a few ideas to make this happen: 1 - upgrade 'nodedev-list' to add an extra 'assigned to' column This is the more straightforward way of exposing the info. A simple 'nodedev-list' call can retrieve which domain is using which nodedev. To preserve the existing usage we can add an "--show-assigned-domains" option to control whether we will display this info. 2 - add an '<assigned_to>' element in nodedev XML definition I'm not a fan of exposing this in this particular XML because we would mix host/hw related attributes with domain info. But it would be easier to pull this off comparing to (1), so I'm mentioning it for the record. I would start by exposing the info for HOSTDEV_SUBSYS_TYPE_PCI hostdevs (--cap pci in nodedev-list). Thanks, DHB
