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:

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.

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!

Please select the "virtio" video device model.

(Also, the kvmarm list is not appropriate for discussing this; please
use  or

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.

use vnc in arm-kvm

2018-05-16 Thread lizhuoyao 
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

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!
