ubuntu guest on RHEL kvm *(x86_64) is failing

Question

I have a x86_64 m/c and i successfully installed Sles12 and RHEL7 guests on this m/c. But while creating a ubuntu guest (64 bit), this is failing.

virt-install --name=ubuntu1 --virt-type=kvm --boot cdrom,hd --network=default,model=virtio --disk /dev/dm-13,size=300,format=raw,bus=virtio,cache=none,sparse=true --memory=8192 --vcpu=2 --location=/home/suse/ubuntu-16.04-server-amd64.iso  --console pty,target_type=serial --graphics none --extra-args 'console=ttyS0,115200n8 serial'
Starting install...

While running with debug, this is expecting i386 ?

Can someone pls suggest?

Answer 1

From debug, it can be see it is indeed looking for i386, which is "default arch".

Exact same problem has been tackled in askubuntu q/a and has been patched to detect architecture from ISO name correctly.

Virt-manager with the patch does not have official release, so one would need to run virt-manager from sources or tinker with existing installation by changing and compiling /usr/share/virt-manager/virtinst/urlfetcher.py file.
