If you install the VM using virt-manager, you can check the device controller options directly. For disks and network interfaces, the "virtio" option will generally give the best performance. As regards the network, the virt-manager defaults should just work, but for other stuff my personal notes say this: Libvirt creates VMs in the libvirt firewall zone, so services must be added there: For NFS: # firewall-cmd --add-service mountd --zone=libvirt # firewall-cmd --permanent --add-service mountd --zone=libvirt # firewall-cmd --add-service nfs --zone=libvirt # firewall-cmd --permanent --add-service nfs --zone=libvirt # firewall-cmd --add-service nfs3 --zone=libvirt # firewall-cmd --permanent --add-service nfs3 --zone=libvirt # firewall-cmd --add-service rpc-bind --zone=libvirt # firewall-cmd --permanent --add-service rpc-bind --zone=libvirt For Samba: # firewall-cmd --add-service samba --zone=libvirt # firewall-cmd --permanent --add-service samba --zone=libvirt # firewall-cmd --add-service samba-client --zone=libvirt # firewall-cmd --permanent --add-service samba-client --zone=libvirt poc _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
