Unable to Start VM

kvm: device requires 67108864 bytes, block backend provides 131072 bytes

Have tried resize disk
# qm resize 100 efidisk0 +256M

But keeps the same message

after a little change on script replacing Variable 'vmdk' to 'qcow2'
and execute a more precise EFIdisk space 'qm resize 100 efidisk0 +65408K'
I am able start the VM, BUT stays here :|

I get this often. Not sure why.
To get things going you can try this from the host machine:

# Make sure VM is disabled:
ha-manager set vm:<VMID> --state disabled
# Open GDISK to modify disk partition map
gdisk /dev/zvol/rpool/vm-<VMID>-disk-<DISK#>
# Once GDISK opens, then just use the W command to re-write the partiion map
# Re-enable (start) VM to verify the VM boots using the disk
ha-manager set vm:<VMID> --state enabled
