#Qemu options download
On the host, download the virtiofs QEMU tree by: Note: An alternative is to build the kernel on the host and pass the kernel on the QEMU command line Īlthough this can take some work to get initrd's to work right. Make -j 8 & make -j 8 modules & make -j 8 modules_install & make -j 8 installīoot the guest and ensure it boots normally.
#Qemu options install
The following config options are selected:īuild and install the kernel in the guest, on most distros this can be most However if you want access to development features, download the virtiofs kernelĬonfigure, build and install this kernel inside your guest VM, ensuring that Image to run under QEMU and a Linux host on which you can build and runĪn appropriately configured Linux 5.4 or later can be used for virtiofs, The instructions assume that you already have available a Linux guest The example virtiofs daemon (virtiofsd).In general it's easier to debug basic issues in this environment than inside Kata Containers.

Make sure you are committing changes to right HDD name, virtioa.qcow2, hda.qcow2. From the EVE CLI, locate the installed image and commit your changes to be used as default for further use in EVE-NG: cd /opt/unetlab/tmp/ 0/3491e0a7-25f8-46e1-b697-ccb4fc4088a2/ 8/ The Node ID can be obtained by right clicking the node on the topology. The Admin user uses POD number 0 by default. The POD number is assigned to your username, and can be found in the EVE GUI, Management/User Management. Find out the POD ID of your used and the Node ID of your newly installed node. On the left side-bar within the lab in the EVE Web-UI choose “Lab Details” to get your lab’s UUID details: In this example: Lab UUID: 3491e0a7-25f8-46e1-b697-ccb4fc4088a2Ĥ.
