Qubes R4.0rc4 - qvm-create's option --root-copy-from -> qubesd protocol error

[brenda...@gmail.com]

Hi folks,

Installed Qubes R4.0rc3, updated dom0/templates. Added the testing repository, updated dom0/templates so I am now at R4.0rc4 (qubes manager returns, huzzah!).

The problem is that I am trying to import a raw root.img file (converted from vmdk using qemu tools) while creating a new StandaloneVM from microsoft's Edge on Win10 OVA file for browser testing.

I am receiving an error in qubesd when calling qvm-create in dom0.

I invoke (with or without the --property kernel='' option):
sudo qvm-create win10 --class standalone --property kernel='' --root-copy-from /home/qubes-user/root.img --label green

The error is:
app: Error creating VM: Got empty response from qubesd. See journalctl in dom0 for details.

I ran journalctl -r and this is the head (of the tail, so reverse order, looks like the important bit is 'protocol error'):

Mea culpa and apologies to all: the properties for "--class" or "--c" are case sensitive.

Substituting 'StandaloneVM' for 'standalonevm' fixed the problem.

Thanks,
Brendan
