Or, more generally, if you are using libvirt and virt-manager then you
want to be looking online for tutorials/documentation involving libvirt,
virt-manager and perhaps virsh and not ones regarding xm/xl, since they
are different toolstacks with different approaches to configuration
management.

I don't know how to do things via the GUI but [0] suggests something
like:
        virsh attach-disk comlag dev/vg0/vm_osol xvda3
would be the virsh equivalent to the "xm block-attach comlag
phy:/dev/vg0/vm_osol /dev/xvda3 w" you mentioned at the start.
