Lock VNC port behind KVM VM?

Question

linux

How can I fix the VNC port for a specific virtual machine so that after rebooting the server and restarting the virtual machines, the port numbering is preserved?

Answer 1

virsh edit --domain "имя виртуалки"
the xml config of the virtual machine opens, there is a graphics section with settings for vnc

Answer 2

if without libvirt, then simply
qemu-system-x86_64 ... -vnc 77 ...
with this parameter the VNC port 5977 will be assigned to this VM
