Building a VM with virt-install

Introduction
|
|
|
|
|
|
|
|
|
|
This assumes that the network will be used in "macvtap" mode. This is
|
|
|
|
|
the preferred method, as it is faster than a regular bridge and
|
|
|
|
|
does not need any additional network configuration on the host.
|
|
|
|
|
|
|
|
|
|
The disadvantage of macvtap is that host-to-vm and vm-to-host
|
|
|
|
|
communication is blocked. This can be worked around with an
|
|
|
|
|
"internal" switch, or by having the macvtap connection bind to a
|
|
|
|
|
second interface.

Creating the VM
|
|
|
|
|
|
|
|
|
|
The following command assumes the OS is "rhel9.1" and the network
|
|
|
|
|
card is "eno1". It should be run as the root user or with sudo, and
|
|
|
|
|
should be run inside tmux for safety.
|
|
|
|
|
|
|
|
|
|
virt-install --name rhel9 \
|
|
|
|
|
--osinfo rhel9.1 \
|
|
|
|
|
--cdrom /var/lib/libvirt/isos/rhel-baseos-9.1-x86_64-dvd.iso \
|
|
|
|
|
--disk path=/var/lib/libvirt/images/rhel9.qcow2,size=20 \
|
|
|
|
|
--network type=direct,source=eno1,source_mode=bridge \
|
|
|
|
|
--boot uefi \
|
|
|
|
|
--vnc
|
|
|
|
|
|
|
|
|
|
Paths and names should be changed as appropriate. The VNC port can be
|
|
|
|
|
found for this example by running "virsh vncdisplay rhel9" from
|
|
|
|
|
another SSH/console session.

For a virtio network card on Windows machines, add ",model=virtio" to
|
|
|
|
|
the --network option. Other useful options are "--ram 4096" for 4 GB
|
|
|
|
|
RAM, and "--vcpus 2" for a dual-CPU guest.
