![]() I tried the same on 18.04 and 20.04 and both worked fine. To fix this, simply delete the VARS file so you could re-create the VM with the same name: $ rm /var/lib/libvirt/qemu/nvram/kubuntu-18.04.3-lts_VARS.fdįirst of all (you did already, but others finding this might wonder as it isn't auto-installed as dependency in 18.04 - it is on later releases) you need to install ovmf $ apt install ovmf Notice that the issue will not occur on other VMs you create with a different name. kubuntu-18.04.3-lts_VARS.fd): libvirtError: internal error: process exited while connecting to monitor: T22:17:50.165625Z qemu-system-x86_64: -drive file=/var/lib/libvirt/qemu/nvram/kubuntu-18.04.3-lts_VARS.fd,if=pflash,format=raw,unit=1: oversized backing file, pflash segments cannot be mapped under 00000000ff800000 It is complaining about the guest VM's VARS (.
