What were you trying to do that didn't work?
Booting the VM for the first time (only the first time) makes it hang, as the firmware refuses to run on a resolution lower than EFI spec mandates
GopNativeResolution: #0: 507x510 ... GraphicsConsole video resolution 507 x 510 ASSERT [GraphicsConsoleDxe] /builddir/build/BUILD/edk2-8736b8fdca/MdeModulePkg/Universal/Console/GraphicsConsoleDxe/GraphicsConsole.c(267): (MaxColumns >= 80) && (MaxRows >= 25)
Resettting the VM makes the problem go away, its only on first boot after VM creation, and not always.
Please provide the package NVR for which bug is seen:
edk2-aarch64-20231122-6.el9.noarch qemu-kvm-8.2.0-11.el9_4.3.aarch64
How reproducible:
Never in our labs, only on customer site.
Steps to reproduce:
On customer setup, the details are potentially irrelevant as it also reproduces via cockpit-machines:
# virt-install --connect qemu:///system --quiet --os-variant rhel9.4 --memory 8192 --name myvm --wait -1 --disk size=16,format=qcow2 --graphics vnc,listen=127.0.0.1 --print-xml=1 > /tmp/myvm.xml # virsh --connect qemu:///system define /tmp/myvm.xml # virsh --connect qemu:///system dumpxml myvm | grep -w mac <mac address='52:54:00:00:00:00'/> # virt-xml -c qemu:///system myvm --edit mac=52:54:00:00:00:00 --network mac=52:54:00:00:00:00,type=bridge,source=bridge0,model=virtio, Domain 'myvm' defined successfully. # virt-install --debug --connect qemu:///system --quiet --os-variant rhel9.4 --reinstall myvm --wait -1 --noautoconsole --cdrom /tmp/rhel-9.4-aarch64-boot.iso
Expected results
The VM boots
Actual results
The VM is stuck on that ASSERT on first boot.
There is no resolution set in the qemu-kvm command line for the virtio-gpu, nor in the libvirt XML.
After some investigation, I found that the resolution may be saved in some Platform Config option saved as EFI VAR somewhere. But we have double checked that:
- The system disk is empty, no EFI vars set there
- The RHEL 9.4 boot ISO also has nothing
- The NVRAM VARS is also the default, there are no resolution settings there.
- The firmware logs don't indicate it loading any config, it seems to just read that incorrect resolution from the virtio-gpu, but then working after a reset is weird.
- It is always 507x510, so its apparently not some random garbage that is read.
- qemu-kvm virtio-gpu device is created with the default resolution and the device properties look correct on the same run the assert is hit
