oh well, it turns out to be actually related, it turns out
virt-aa-helper is skipping the code file of ovmf:

Title:
Initialization of device cfi.pflash01 failed: Block node is read-only
Status in libvirt:
New
Status in QEMU:
Invalid
Bug description:
Hi,
I have several vms defined in libvirt using ovmf for uefi, since a later
update of my server I'm unable to start any of the domains defined. This is
an example of the output given:
# virsh start os-1
error: Failed to start domain os-1
error: internal error: qemu unexpectedly closed the monitor:

where /var/lib/libvirt/qemu/nvram/os-1-ovmf.fd is a copy of
/usr/share/edk2-ovmf/OVMF_VARS.fd. An the extract from my
/etc/libvirt/qemu.conf to define ovmf:
...
# Location of master nvram file
#
# When a domain is configured to use UEFI instead of standard
# BIOS it may use a separate storage for UEFI variables. If
# that's the case libvirt creates the variable store per domain
# using this master file as image. Each UEFI firmware can,
# however, have different variables store. Therefore the nvram is
# a list of strings when a single item is in form of:
# ${PATH_TO_UEFI_FW}:${PATH_TO_UEFI_VARS}.
# Later, when libvirt creates per domain variable store, this list is
# searched for the master image. The UEFI firmware can be called
# differently for different guest architectures. For instance, it's OVMF
# for x86_64 and i686, but it's AAVMF for aarch64. The libvirt default
# follows this scheme.
nvram = [
"/usr/share/edk2-ovmf/OVMF_CODE.fd:/usr/share/edk2-ovmf/OVMF_VARS.fd",
]
...
This setup used to work one month ago, now it's setup with:
QEMU emulator version 3.1.0
libvirt-5.0.0
linux-4.19.20
Any help appreciated.
Best regards.
José
