Public bug reported:
For many years I've been able to create x86 VMs on an x86_64 host with a
command line like the following:
$ virt-install --connect=qemu:///system --name=sec-disco-i386
--arch=i386 --cpu=host-passthrough --ram=1280 --disk=path=.../sec-
disco-i386.qcow2,size=10,format=qcow2,sparse=true,bus=virtio --virt-
type=kvm --hvm --cdrom=.../ubuntu-19.04-mini-i386.iso --os-type=linux
--os-variant=generic --graphics=spice --input=tablet
--network=network=default,model=virtio --video=qxl --noreboot
but today on a 19.04 amd64 host when I tried it, I got:
ERROR Host does not support virtualization type 'hvm' for arch 'i386'
I checked 'virsh capabilities' and sure enough, <arch name='i386'> is
*not* listed as a guest, but <arch name='i686'> is. I then tried with
--arch=i686 and it worked.
I hadn't created an i386 VM in a while, so not sure when things stopped
working. I looked at an 18.04 host and saw it also does not have <arch
name='i386'>, but I and others have created VMs with --arch=i386 all the
time on 18.04. I'm not sure if an alias for i386 was dropped or
something....
