Hi guys.
I cannot start a domain - I wonder if the firmware, in xml,
have anything to do with it or issue is different?
Jul 17 11:07:41 virtqemud[5658]: Unable to read from
monitor: Connection reset by peer
Jul 17 11:07:41 virtqemud[5658]: internal error: QEMU
unexpectedly closed the monitor (vm='ubusrv2'):
2026-07-17T09:07:41.089484Z qemu-kvm: -blockdev

Above happens with:
<os firmware='efi'>
<type arch='x86_64' machine='pc-q35-rhel10.2.0'>hvm</type>
<firmware>
<feature enabled='no' name='enrolled-keys'/>
<feature enabled='yes' name='secure-boot'/>
</firmware>
<loader readonly='yes' type='pflash'
format='raw'>/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd</loader>
<nvram template='/usr/share/edk2/ovmf/OVMF_VARS.fd'
templateFormat='raw'
format='raw'>/var/lib/libvirt/qemu/nvram/ubusrv2_VARS.fd</nvram>
if I do not use EFI than domain starts, no above virtqemud
errors, but guest does not boot, expectedly I think - I used
to boot a ok.
qemu-img shows no issues.
Any thoughts?
many thanks, L.
