Libvirt NVME support
by Suraj Kasi 23 Nov '20

23 Nov '20

Hi, We wanted to check if it’s possible to specify a disk’s target as nvme (so that the disk shows up as a nvme disk to the guest VM). Per libvirt documentation it looks like (since Libvirt 6.0.0) we can specify the disk type as nvme and disks source as a nvme. But the documentation does not say anything about being specify the disk’s target as nvme. Is it possible to present the disk to the guest as a nvme disk, if so how? Example from Libvirt documentation (https://libvirt.org/formatdomain.html) ----- <disk type='nvme' device='disk'> <driver name='qemu' type='raw'/> <source type='pci' managed='yes' namespace='1'> <address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </source> <target dev='vde' bus='virtio'/> </disk> ----- But we want to do something similar to the following: two vNVMe controllers where the first one has one namespace and the second one has two namespaces ----- # first NVMe controller, one namespace <disk type='network' device='disk'> <driver name='qemu' type='raw'/> <source protocol='iscsi' name='iqn.2013-07.com.example:iscsi-nopool/123'> <host name='example.com' port='3260'/> <auth username='myuser'> <secret type='iscsi' usage='libvirtiscsi'/> </auth> </source> <target dev='nvme0' bus='nvme'/> </disk> # second NVMe controller, first namespace <disk type='network' device='disk'> <driver name='qemu' type='raw'/> <source protocol='iscsi' name='iqn.2013-07.com.example:iscsi-nopool/456'> <host name='example.com' port='3260'/> <auth username='myuser'> <secret type='iscsi' usage='libvirtiscsi'/> </auth> </source> <target dev='nvme1' namespace='1' bus='nvme'/> </disk> # second NVMe controller, first namespace <disk type='network' device='disk'> <driver name='qemu' type='raw'/> <source protocol='iscsi' name='iqn.2013-07.com.example:iscsi-nopool/789'> <host name='example.com' port='3260'/> <auth username='myuser'> <secret type='iscsi' usage='libvirtiscsi'/> </auth> </source> <target dev='nvme1' namespace='2' bus='nvme'/> </disk> ----- If in case this is not yet supported, would it be merged if we were to implement it? Thanks, Suraj

[libvirt PATCH 0/3] Add missing feature detection to sync tool in cpu_map
by Tim Wiederhake 23 Nov '20

23 Nov '20

sync_qemu_i386.py in src/cpu_map is a tool to sync CPU models from qemu with libvirt. It currently has no provisions for detecting new features that are not implemented in libvirt yet. This series changes that. See also https://www.redhat.com/archives/libvir-list/2020-November/msg00271.html. libvirt is currently missing three x86 CPU models: Denverton, KnightsMill, and Snowridge; and seven features: core-capability, fsrm, perfctr-core, split-lock-detect, vmx-eptp-switching, vmx-pml, and vmx-rdseed-exit. For the Snowridge CPU model and the core-capability and split-lock-detect features, see also https://www.redhat.com/archives/libvir-list/2020-November/msg00924.html. Tim Wiederhake (3): cpu_map: sync_qemu_i386: Detect features missing in translation table cpu_map: sync_qemu_i386: Add features missing in translation table cpu_map: sync_qemu_i386: Detect features missing in libvirt src/cpu_map/sync_qemu_i386.py | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) -- 2.26.2

[libvirt PATCH 0/8] Drop 'monitor' from modern x86 CPU models
by Jiri Denemark 23 Nov '20

23 Nov '20

Doing so would normally break migration to older libvirt, but most of the patches in this series prepare an infrastructure for removing features from existing CPU models while maintaining backward compatibility during migration.

[PATCH] virDomainAuthorizedSSHKeysSet: Use uint for @nkeys
by Michal Privoznik 23 Nov '20

23 Nov '20

When introducing the API I've mistakenly used 'int' type for @nkeys argument which does nothing more than tells the API how many items there are in @keys array. Obviously, negative values are not expected and therefore 'unsigned int' should have been used. Reported-by: Daniel P.
