hi everyone:
currently, I meet a problem about qemu.Use virt-install order to create a domain, return a failed:
order: virt-install -n centos-gg -r 1024 --disk centos-gg.img,format=qcow2,size=10 --cdrom /home/Centos-7-aarch64-Everything.iso --graphics vnc, listen=0.0.0.0
failed: this QEMU does not support 'cirrus' video device
This issue only happen in arm,and it's ok in x86. I get some message in the internet that VGA is a (more or less) x86-specific standard, not available on ARM. Right?
tool: qemu-2.12.0 libvirt-3.2.0
Thanks!

VGA, or rather the way it is used in the Linux kernel cannot be
realistically supported on ARM at the moment. But if you want a
graphical display, why not using virtio-gpu?
It works well enough for me, although I do not use libvirt, and stick
to just qemu. For the record, this is the relevant section of my command
line:
-device virtio-gpu-pci -display sdl -device virtio-tablet-pci -device
usb-ehci,id=ehci -device usb-kbd
I've just checked with VNC:
-device virtio-gpu-pci -display vnc=127.0.0.1:0,to=100 -device
virtio-tablet-pci -device usb-ehci,id=ehci -device usb-kbd
and although it is much slower (not surprising), it seems to work just
as well.
Hope this helps,
M.

Please select the "virtio" video device model.
(Also, the kvmarm list is not appropriate for discussing this; please
use <https://www.redhat.com/mailman/listinfo/virt-tools-list> or
<https://www.redhat.com/mailman/listinfo/libvirt-users> instead.)
Thanks

select virtio video also failed.
order：virt-install -n centos-gg -r 1024 --disk centos-gg.img,format=qcow2,size=10 --cdrom /home/lzy/CentOs-7-aarch64-Everything.iso --video virtio
failed: PCI controller at index 1 (0x01) has bus='0x01',but index must be larger than bus.
(I have tryed in other mail list....)

you said VGA cannot be realistically supported on ARM at the moment,then wrote it's ok checked with VNC.Did you experiment in x86 or arm?
There is likely no -device(--device) parameter in "virt-install -h". Sorry, I'm not familiar with virt-install much. Can you show the order you use?
Thanks!

What would be the point in trying an x86 box, as we both know that it
works? I checked using virtio-gpu, on an arm64 machine (rk3399 based
chromebook). Not x86, not VGA.

OK, you simply haven't read my email. I said:

>> my command line:
To repeat: I don't use libvirt, but QEMU directly. If you have libvirt
questions, please do as Laszlo suggested and ask the question on the
libvirt mailing list.
