kubevirt: virt-handler fails to start on alpine 3.16 k3s cluster

What happened: virt-handler does not start on alpine 3.16 k3s cluster

What you expected to happen: I expect all pods of kubevirt started.

How to reproduce it (as minimally and precisely as possible):

1. I installed k3s cluster on three nodes, one master and other two agents. curl -sfL https://get.k3s.io | sh -

Pramod-node1:~/.kube# kubectl get nodes -o wide NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME pramod-node3 Ready <none> 16m v1.24.6+k3s1 147.75.71.91 <none> Alpine Linux v3.16 5.15.47-0-lts containerd://1.6.8-k3s1 pramod-node2 Ready <none> 16m v1.24.6+k3s1 147.75.49.193 <none> Alpine Linux v3.16 5.15.47-0-lts containerd://1.6.8-k3s1 pramod-node1 Ready control-plane,master 20m v1.24.6+k3s1 139.178.89.1 <none> Alpine Linux v3.16 5.15.47-0-lts containerd://1.6.8-k3s1

1. Then installed KubeVirt

export RELEASE=$(curl https://storage.googleapis.com/kubevirt-prow/release/kubevirt/kubevirt/stable.txt) kubectl apply -f https://github.com/kubevirt/kubevirt/releases/download/${RELEASE}/kubevirt-operator.yaml kubectl apply -f https://github.com/kubevirt/kubevirt/releases/download/${RELEASE}/kubevirt-cr.yaml

Pramod-node1:~/.kube# kubectl logs -n kubevirt virt-handler-w2ldj -c virt-launcher error: failed to get emulator capabilities error: internal error: Failed to start QEMU binary /usr/libexec/qemu-kvm for probing:

Those ^^^ are the only messages I see in the logs

My CPU is AMD EPYC 7402P 24-Core Processor which supports HW virtualization I did check kvm modules are loaded.
