Libvirt(since 9.4.0) allows to control this attribute for virtio-{mem,pmem}.
Now add it into virt-install.
Example:
virt-install \
--name test \
--os-variant opensusetumbleweed \
--cdrom /isos/openSUSE-Tumbleweed-DVD-x86_64-Current.iso \
--disk /vms/tw/disk0.qcow2 \
--vcpu 2 \
--cpu cell0.cpus=0,cell0.memory=4194304,\
cell1.cpus=1,cell1.memory=4194304 \
--memory maxMemory=65536,maxMemory.slots=8 \
--memdev model=virtio-mem,\
target.node=0,\
target.block=2048,\
target.size=8192,\
target.requested=2097152,\
target.address_base=0x280000000 \
--memdev model=virtio-pmem,\
source.path=/tmp/virtio_pmem,\
target.size=4096,\
target.address_base=0x480000000
It results in the following domain XML snippet:
<memory model='virtio-mem'>
<target>
<size unit='KiB'>8388608</size>
<node>0</node>
<block unit='KiB'>2048</block>
<requested unit='KiB'>2097152</requested>
<current unit='KiB'>0</current>
<address base='0x280000000'/>
</target>
<alias name='virtiomem0'/>
<address type='pci' domain='0x0000' bus='0x07' slot='0x00' function='0x0'/>
</memory>
<memory model='virtio-pmem' access='shared'>
<source>
<path>/tmp/virtio_pmem</path>
</source>
<target>
<size unit='KiB'>2097152</size>
<address base='0x480000000'/>
</target>
<alias name='virtiopmem0'/>
<address type='pci' domain='0x0000' bus='0x08' slot='0x00' function='0x0'/>
</memory>
