virsh get disk location of all VMs in a Array

for i in $(virsh list --all | awk '{print $2}'|grep -v Name);
  do
    virsh domblklist $i --details | awk '{print $4}'|grep -v Source;
  done

I get

/sdc/kvm_strage/vm1.qcow2
/sdc/kvm_strage/vm1_1.qcow2
-


/sdc/kvm_strage/vm2.qcow2
-


/sdc/kvm_strage/vm3.qcow2
/sdc/kvm_strage/vm3_1.qcow2
-

But I want to get the path in a array and exclude the "-" like

my_array=(/sdc/kvm_strage/vm1.qcow2 /sdc/kvm_strage/vm1_1.qcow2 /sdc/kvm_strage/vm2.qcow2 /sdc/kvm_strage/vm3.qcow2 /sdc/kvm_strage/vm3_1.qcow2)

How to do that?

Solution

  • Here is an alternative way:

    declare -a my_array=($(for vm in $(virsh list --all --name); do
    virsh domblklist $vm --details | awk '/disk/{print $4}'
done))

    EDIT: I just noticed I missed a pair of parenthesis when setting the value of my_array.
