TROUBLESHOOTING:
If vms don't come up maybe because a vagrant destroy was interrupted, this is a drastic solution that tends to work: 

virsh list --all
virsh destroy <THE_MACHINE> 
virsh undefine <THE_MACHINE> --snapshots-metadata --managed-save
virsh vol-list default
virsh vol-delete --pool default <THE_VOLUME>
rm -f /var/lib/libvirt/images/* 
systemctl restart libvirtd

vagrant up
vagrant ssh vmx-vcp-01

TROUBLESHOOTING AUTOMATED DRAFT:

virsh list --all  | egrep -v "Name|------" | awk '{print $2}' > /var/tmp/temp
while read -r line; do echo "virsh destroy $line" ; done < /var/tmp/temp
while read -r line; do echo "virsh undefine $line --snapshots-metadata   --managed-save" ; done < /var/tmp/temp
virsh vol-list default | egrep "^ " | egrep -v Name | cut -d' ' -f 2 > /var/tmp/temp2
while read -r line; do echo "virsh vol-delete --pool default $line" ; done < /var/tmp/temp2
rm -f /var/lib/libvirt/images/*
systemctl restart libvirtd
