[libvirt] [PATCH v3 0/8] Support qemu-system-arm vexpress-a9

[Richard W.M. Jones]

I tried this patchset and it works at least as far as being able to
get the libguestfs appliance up and running on ARM (with KVM) using
the libvirt backend.  Virtio-scsi & virtio-serial work.

Some issues however:

 - Why is arch="armv7l"?  Why not just "arm", or "armv7hl"?

 - I had to force the <emulator> to be /usr/bin/qemu-system-arm.
   Otherwise libvirt tries to run /usr/bin/qemu-kvm.  May be related
   to RHBZ#1005581.

 - I had to add -machine kernel_irqchip=off (for KVM):

 - Setting <cpu mode="host-model"/> confuses libvirt completely.
