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!

Have a good day

Right? > tool: qemu-2.12.0 libvirt-3.2.0__ 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. -- Jazz is not dead.

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. > 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? OK, you simply haven't read my email. I said: >> 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: 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. M. -- Jazz is not dead.
