consume existing tap device when libvirt / qemu run as different users
Hello,
I'm having some doubts about consuming an existing - already
configured - tap device from libvirt (with `managed='no' ` attribute
set).
In KubeVirt, we want to have the consumer side of the tap device run
without the NET_ADMIN capability, which requires the UID / GID of the
tap creator / opener to match, as per the kernel code in [0]. As such,
we create the tap device (with

Create VM w/ cache=none on tmpfs
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

consuming pre-created tap - with multiqueue
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:
```

I'm seeing the following issue when attempting to update the guest's

Transient permission denied errors when sending audit logs
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.

Getting "Unable to set XATTR" on libvirt 5.6.0 inside containers
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
