search docs on www.libvirt.org
by Wolfgang Rohdewald
Hi,
your website allows to search Docs. This automatically uses Google.
IMHO it is very unfriendly not to warn people that an external data harvester
is involved in your local search.
Please consider adding a warning.
BTW your website massively violates EU data privacy rights. You have
no Impressum and no info about your privacy policy. Your website does
not even have a contact address.

Shared memory usage
by Sánta, Márton (ext)
Dear Users,
I tried out shared memory using libvirt. When I configure it in the XML (ivshmem-plain), I have to provide a name for it and after starting the VM I can see the appropriate file on the host in the /dev/shm/ directory. My problem is that I could not find any official documentation about the usage of that shared memory. On the guest side, I have found the PCI device related to it, but I do not know how to use it. Is there any available command line tool to read from or write to this memory or is it only possible with a user application? Could you provide my what is the most common solution for this?
Thank you in advance for your reply and help!
Best regards,
Márton Sánta

a VM with secure boot does not survive a reset
by lejeczek
Hi guys.
A VM created with:
-> $ virt-install --boot uefi --name=client-efi-secureboot
--os-variant centos-stream9 --memory $((4*1024))
--graphics=vnc,listen=0.0.0.0 --accelerate --cpuset 2 --cpu
host-model --pxe --disk=/00-VMsy/client-efi-secureboot.qcow2
--network network=10_3_1,,model=virtio
when *virsh reset* while running will power off, instead of
*restart*. Whereas:
-> $ virt-install --boot
uefi,firmware.feature0.name=secure-boot,firmware.feature0.enabled=no
--name=client-efi-no-secureboot --os-variant centos-stream9
--memory $((4*1024)) --graphics=vnc,listen=0.0.0.0
--accelerate --cpuset 2 --cpu host-model --pxe
--disk=/00-VMsy/client-efi-no-secureboot.qcow2 --network
network=10_3_1,,model=virtio
does behave as expected when *reset*.
libvirt-libs-9.5.0-6.el9.x86_64
BTW. Where should bug reports go to theses days - I'm trying
Redhat's Jira but cannot file a BZ in _RHEL_ category. I get
no errors nor warnings but Jira won't let me file anything
there, but I can in Centos category.
thanks, L.

pxe efi boot - bdsdxe boot0002 access denied
by lejeczek
Hi guys
I have VMs which fail to boot with error as per the subject.
I suspect this is due to:
<os firmware='efi'>
<type arch='x86_64' machine='pc-q35-rhel9.2.0'>hvm</type>
<firmware>
<feature enabled='yes' name='enrolled-keys'/> <--- HERE
<feature enabled='yes' name='secure-boot'/> <---- HERE ?
</firmware>
<loader readonly='yes' secure='yes'
type='pflash'>/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd</loader>
<nvram
template='/usr/share/edk2/ovmf/OVMF_VARS.secboot.fd'>/var/lib/libvirt/qemu/nvram/centos-efi_VARS.fd</nvram>
<boot dev='network'/>
<boot dev='hd'/>
</os>
Would you have any thoughts on how to fix, to work around it?
many thanks, L.
