Immediate "system reset" when booting UEFI?
by Lars Kellogg-Stedman
Hey folks,
I'm running libvirt 10.1.0/qemu-system-x86-core-9.0.1-1.fc40.x86_64 on Fedora
40. I'm trying to boot an Ubuntu image in UEFI mode, like this:
virt-install -r 2048 -n ubuntu.virt --os-variant ubuntu24.04 \
--disk pool=default,size=10,backing_store=mantic-server-cloudimg-amd64.img,backing_format=qcow2
\
--cloud-init root-ssh-key=$HOME/.ssh/id_ed25519.pub \
--boot uefi
This results in the domain booting up and then immediately resetting:
BdsDxe: loading Boot0001 "UEFI Misc Device" from
PciRoot(0x0)/Pci(0x2,0x3)/Pci(0x0,0x0)
BdsDxe: starting Boot0001 "UEFI Misc Device" from
PciRoot(0x0)/Pci(0x2,0x3)/Pci(0x0,0x0)
Reset System
Domain creation completed.
At this point, the machine is actually powered down and needs to be
restarted manually:
virsh start ubuntu.virt
This works fine, and the domain boots successfully, but now the cloud-init
metadata provided by the `--cloud-init` option to `virt-install` is no longer
available (because this is no longer the initial, virt-install managed boot of
the domain).
What is causing the firmware to reset the system when it first boots?

trustGuestRxFilters broken after upgrade to Debian 12
by Paul B. Henson
We've been running Debian 11 for a while, using sr-iov:
<network>
<name>sr-iov-intel-10G-1</name>
<uuid>6bdaa4c8-e720-4ea0-9a50-91cb7f2c83b1</uuid>
<forward mode='hostdev' managed='yes'>
<pf dev='eth2'/>
</forward>
</network>
and allocating vf's from the pool:
<interface type='network' trustGuestRxFilters='yes'>
<mac address='52:54:00:08:da:5b'/>
<source network='sr-iov-intel-10G-1'/>
<vlan>
<tag id='50'/>
</vlan>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
After upgrading to Debian 12, when I try to start any vm which uses the
trustGuestRxFilters option, it fails to start with the message:
error: internal error: unable to execute QEMU command 'query-rx-filter':
invalid net client name: hostdev0
If I remove the option, it starts fine (but of course is broken
functionality wise as the option wasn't there just for fun :) ).
Any thoughts on what's going on here? The Debian 12 versions are:
libvirt-daemon/stable,now 9.0.0-4
qemu-system-x86/stable,now 1:7.2+dfsg-7+deb12u3
I see Debian 12 backports has version 8.1.2+ds-1~bpo12+1 of qemu, but no
newer versions of libvirt. I haven't tried the backports version to
see if that resolves the problem.
Thanks much...
