Esxi deploy failed - maas 2.9

Hello everybody.
I trying to evaluate bare metall as a service with MAAS. I set up a testing environment in vmware, - maas server and some “target” vm.
First step - deploy of ubuntu from maas. It was ok, all as wrote in documentation.
Second step - deploy of custom debian image. With some patching and hacking it worked nice.
Last step - I try to deploy esxi vmvisor image. And here is a problem (problems).
Deploy finished with error:
ValueError: Did not find any filesystem on [‘sda’] that contained one of [‘curtin’, ‘system-data/var/lib/snapd’, ‘snaps’]
Did not find any filesystem on [‘sda’] that contained one of [‘curtin’, ‘system-data/var/lib/snapd’, ‘snaps’].
But esxi operation system was set on vm, and (if I disable pxe) it can boot from disk.
I tried to add “make /curtin” to KS, I tried to remove every lines from curtin-hook and add “echo 1” with intention to get zero exit code, and re-create esxi image, but no luck.

Please help me fix this.

If it can help with debug - earlier in log I see this:

mount: /tmp/tmp_6gfp16t: unknown filesystem type ‘VMFS_volume_member’.

@readthebook, did you ever figure this one out?
