Hi Daniel, thanks for the quick reply we did try to override SMBIOS host_uuid_source = "machine-id" and it didn't work even that nodes have different [root@modi01 kubevirt]# ./cluster-up/ssh.sh kind-1.17.0-worker root@kind-1:/# cat /etc/machine-id [root@modi01 kubevirt]# ./cluster-up/ssh.sh kind-1.17.0-control-plane root@kind-1:/# cat /etc/machine-id

Hi, I've seen that in the past, libvirt couldn't start VMs when the disk image was stored on a file system that doesn't support direct I/O having the 'cache=none' configuration [0]. On the KubeVirt project, we have some storage tests on a particular provider which does just that - try to create / start a VM whose disk is on tmpfs and whose definition features

Hi, In kubevirt we are running into a strange permission problem on libvirt-5.0. We see transient "Permission Denied" errors when "virAuditSend" wants to send an audit log. [1] shows the logs of one of these containers. Here an example: {"component":"virt-launcher","level":"warning","msg":"Failed to send audit message

KubeVirt is a custom resource (a kind of plugin) for Kubernetes which adds support for running virtual machines. As part of this they have the same problems as everyone else of how to import large disk images into the system for pets, templates, etc. As part of the project they've defined a format for embedding a disk image into a container (unclear why? perhaps so these can be distributed

Hello, On KubeVirt, we are trying to pre-create a tap device, then instruct libvirt to consume it (via the type=ethernet , managed='no' attributes). It works as expected, **unless** when we create a multi-queue tap device. The difference when creating the tap device is that we set the multi-queue flag; libvirt throws the following error when consuming it: ``` LibvirtError(Code=38,

Hi, We are updating KubeVirt to libvirt 5.6.0. Before that we were running on 5.0.0. It seems like something regarding setting xattrs on files has changed, because with libvirt 5.6.0 we are getting the following error: ``` Unable to set XATTR trusted.libvirt.security.dac on /var/lib/libvirt/qemu/domain-410-default_vmi-fedora: Operation not permitted') ``` The main problem is for us is that

Fixes some of the more egregious problems with v1, and also applies properly to the head of git without needing any other patches. Rich.

Hi, In kubevirt, we discovered [1] that whenever e1000 is used for vNIC, link on the interface becomes ready several seconds after 'ifup' is executed, which for some buggy images like cirros may slow down boot process for up to 1 minute [2]. If we switch from e1000 to virtio, the link is brought up and ready almost immediately. For the record, I am using the following versions: - L0

Hi all, I'm aware that it is possible to plug pre-created macvtap devices to libvirt guests - tracked in RFE [0]. My interpretation of the wording in [1] and [2] is that it is also possible to plug pre-created tap devices into libvirt guests - that would be a requirement to allow kubevirt to run with less capabilities in the pods that encapsulate the VMs. I took a look at the libvirt code

https://github.com/kubevirt/containerized-data-importer/issues/1520 Hi Eric, We had a question from the Kubevirt team related to the above issue. The question is roughly if it's possible to calculate the checksum of an image as an nbdkit filter and/or in the qemu block layer. Supplemental #1: could qemu-img convert calculate a checksum as it goes along? Supplemental #2: could we detect
